Implementing Electronic Invoicing through Fonoa **Rating:** 4.5/5.0 stars **Reviewed by:** Dushan B. | Senior Legal Counsel, Mid-Market (51-1000 emp.) **Reviewed Date:** July 07, 2025 **What do you like best about Fonoa?** In our software, we utilize Fonoa for our Clients in the Billing module. I would like to highlight several aspects of Fonoa: - The technology is facilitating seamless integration. - Ul and API are intuitive and user-friendly - The Customer Support Team responds promptly to reported issues and proactively informs us about any changes or observations. **What do you dislike about Fonoa?** Areas for improvement: - Ul requires more features **What problems is Fonoa solving and how is that benefiting you?** Implementing Electronic Invoicing through Fonoa. Fonoa is solving one of the most complex challenges faced by global businesses — managing e-invoicing and tax compliance across multiple countries with constantly changing regulations. Traditionally, this required manual oversight, local expertise, and multiple systems, which increased both cost and risk. Fonoa centralizes these processes into a single, automated platform that ensures every transaction is compliant in real time, regardless of jurisdiction. **Official Response from Aubrey Harper:** > Thanks for sharing your experience. Love that the integration has been smooth and that the UI, API, and support have all contributed to a positive experience, just what we hope to hear! Appreciate the note on UI features as well—that kind of feedback helps guide where we focus next. Excited to keep supporting your e-invoicing journey. ### 2. Great partner for eCommerce tax validation **Rating:** 4.0/5.0 stars **Reviewed by:** Bjoernar S. | Senior EMEA eComm Platform Manager, Enterprise (> 1000 emp.) **Reviewed Date:** October 10, 2025 **What do you like best about Fonoa?** Fonoa is very easy to work with and brings a great deal of technical expertise. Support queries are handled promptly as well. For a multinational business, having a knowledgeable partner who simplifies the implementation of both country-specific and cross-border tax validations is essential. **What do you dislike about Fonoa?** I am not particularly satisfied with the pricing model, as I find it to be on the expensive side. The cost for lookups that exceed the agreed contract volume is also quite high. Since this is a new implementation, accurately estimating the required volume can be challenging. **What problems is Fonoa solving and how is that benefiting you?** The platform offers B2B VAT ID validation for eCommerce, as well as validation for individual tax numbers. This functionality is useful for ensuring the accuracy of tax information in business transactions. ### 3. Fonoa delivers on compliance and transparency **Rating:** 4.5/5.0 stars **Reviewed by:** Karen Y. | Product Manager, Mid-Market (51-1000 emp.) **Reviewed Date:** July 31, 2025 **What do you like best about Fonoa?** Fonoa provides a strong layer of confidence when it comes to invoicing compliance and reporting obligations across multiple countries. It uses a single API, which is amazing for scaling to multiple countries. One of the most valuable aspects is how it handles the connection to local tax authorities. This removes a huge operational and compliance burden from our internal teams. I also really appreciate the transparency it offers. We can easily track what has been reported, the reporting status, and view any potential issues that need attention. The country-specific integration guides are particularly helpful. They save a lot of time by summarizing the key technical and legal requirements in a clear and accessible way. Overall, Fonoa has made it significantly easier to scale operations into new markets without needing to build deep tax expertise in-house for each one. **What do you dislike about Fonoa?** The biggest challenge with Fonoa is its pricing model. While the product delivers clear value, especially in terms of compliance and automation, the cost can become quite high, particularly for businesses with growing transaction volumes, as pricing is tied to usage. This makes it somewhat difficult to forecast costs, and it can become a limiting factor when planning large-scale rollouts or onboarding new countries. That said, the product is solid overall, and we continue to rely on it for our most important compliance workflows. **What problems is Fonoa solving and how is that benefiting you?** Fonoa is helping us solve the complex and constantly evolving challenge of tax compliance across multiple countries. Specifically, it automates the generation and reporting of electronic invoices in markets with mandatory real-time reporting to local tax authorities, such as Hungary and Spain. This removes the need for manual processes, local integrations, or in-depth in-house expertise for each country's requirements. The benefit is twofold: operational efficiency and compliance risk reduction. We can expand into new countries faster and more confidently, knowing that we’re meeting local invoicing laws. It also gives our finance and compliance teams peace of mind, as they have visibility into what has been reported, what failed, and why. This reduces the risk of audit issues or regulatory fines. Overall, Fonoa enables us to scale compliantly, save internal resources, and operate with greater transparency in regulated markets. **Official Response from Aubrey Harper:** > Karen, thanks for such a comprehensive review. It’s great to hear that Fonoa has helped reduce the burden on your internal teams while giving you visibility and confidence across markets. That’s exactly the kind of impact we hope to make. We also appreciate your honest feedback on pricing. We understand that usage-based models can bring challenges when forecasting for growth, and that’s something we’re continuing to evaluate as we scale. Your input is incredibly valuable as we think about how to best support customers at every stage. Glad to be part of your compliance journey, and looking forward to helping you expand into even more markets. ### 4. Great to company to work together with and products are quickly improving on their end **Rating:** 4.0/5.0 stars **Reviewed by:** Kirsten B. | Global director of Indirect tax, Enterprise (> 1000 emp.) **Reviewed Date:** October 09, 2025 **What do you like best about Fonoa?** The team is highly responsive and always willing to help. FOnoa brings together strong expertise in both tax and IT, which is evident in their approach. Whenever issues arise, they are resolved promptly. About the Tax engine: the process of going live with new tax registrations is smooth and efficient. **What do you dislike about Fonoa?** Currently I cannot see the rules of my own individual Taxengine for the company.It would be very helpful to have greater visibility in this area, although I understand that this feature is planned for the future. **What problems is Fonoa solving and how is that benefiting you?** We currently use the Tax lookup tool, the tax engine, and the e-invoicing feature. It enables us much fast to raise compliant invoices in 100+ jurisdictions; especially in US ### 5. Expansion made easy, and few points to improve on **Rating:** 4.5/5.0 stars **Reviewed by:** Maret K. | Commerce Specialist, Enterprise (> 1000 emp.) **Reviewed Date:** July 29, 2025 **What do you like best about Fonoa?** From the initial integration to implementing new services, Fonoa team has been exceptional in providing the service and support to Bolt for expanding to new markets and being compliant in the existing ones. Once the API has been integrated, adding new markets to use the service, has been relatively easy. The country guides are clear and if there are corner cases due to the business logic, troubleshooting and support is a collaborative effort from both customer support, engineering and product teams. Fonoa is agile and in case we would like to expand to a market where they do not have presence yet, they work with. the customer to find a solution together. **What do you dislike about Fonoa?** While the products in general work very well, there have been cases where business has been disrupted due to changes in the error messages or API that was not communicated ahead of the change taking place. Self service dashboards have improved overtime but could still have few additional features that would make analysing the data easier. **What problems is Fonoa solving and how is that benefiting you?** Fonoa is helping us to stay compliant in the evolving Billing and Tax compliance world, by * validating the supplier and customer billing details * being the certified provider for sending e-invoices on behalf of our customers and doing live reporting to Tax Authorities * giving us insight to possible upcoming changes that their Tax Consultants have learned about **Official Response from Aubrey Harper:** > Thanks for the detailed feedback, Maret. We’re really happy to hear that working with our team has made expanding into new markets smoother and more collaborative for Bolt. It’s especially encouraging to know the guides, support, and flexibility have helped you stay compliant while scaling. We also appreciate the heads-up on where we can do better. Clearer communication around changes and continued improvement of our dashboards are both top of mind, and your input helps us get there faster. Thanks for your thoughts. ### 6. Great partner with custom tailored solutions, great care and high coverage **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Enterprise (> 1000 emp.) **Reviewed Date:** October 10, 2025 **What do you like best about Fonoa?** Fonoa's greatest strength lies in its ability to adapt to the unique business needs and models of its clients. Having collaborated with them on several projects, I have been consistently impressed by the flexibility of their centralized solutions. In various markets, Fonoa's tailored approaches have been essential for meeting compliance requirements that would have otherwise taken us much longer to address. This also reflects in ease of use and initial integration. The Fonoa team demonstrates a high level of professionalism and care, not only during the initial stages of collaboration but also in their ongoing support. They regularly conduct check-ins, monitor our business, and work to enhance the partnership. This proactive approach ensures that we receive timely solutions, especially when new compliance requirements arise. I also appreciate working with a team that is versatile and willing to take on diverse responsibilities. Fonoa does not restrict itself to tax compliance alone; they provide additional value through features related to identity, governance, and more. **What do you dislike about Fonoa?** For a while, Fonoa's most apparent area for improvement was its limited ability to adapt to the diverse needs of businesses across various industries—in other words, how legal requirements are applied in practice within different domains. However, over the past year or so, this aspect has improved significantly and has now become one of Fonoa's strongest features. They are now able to take into account a business's model, specific needs, and industry during implementation, which allows them to offer much more flexible solutions. **What problems is Fonoa solving and how is that benefiting you?** Fonoa serves as our partner, supporting us with reporting and compliance requirements across different markets. They provide solutions for e-invoicing, fiscalization, reporting, and identity management. ### 7. Excellent service **Rating:** 5.0/5.0 stars **Reviewed by:** Dawn W. | Senior Tax Accountant, Enterprise (> 1000 emp.) **Reviewed Date:** October 09, 2025 **What do you like best about Fonoa?** What I like best about Fonoa is their fantastic customer support. From the start of our onboarding, the team has been incredibly responsive and easy to work with. We’ve had regular check-ins with our account team, and they always make sure we’re supported and moving in the right direction. They’re also very committed to meeting deadlines and following through on what they promise, which has made the whole process smooth and stress-free. It really feels like they care about their customers and want to make sure everything goes right. Overall, Fonoa has been great to work with — reliable, communicative, and genuinely invested in our success. **What do you dislike about Fonoa?** Fonoa doesn’t yet have all the features we need in a sales tax engine, but the team has been very proactive and transparent about their roadmap. They’re clearly dedicated to building out the functionality we need and are receptive to feedback. It’s great to see how invested they are in meeting customer expectations and continuously improving the product. **What problems is Fonoa solving and how is that benefiting you?** Fonoa is helping us replace our internally maintained tax engine, which has significantly streamlined our tax determination process. By moving to Fonoa, we’re reducing the amount of manual work and maintenance required on our side, improving accuracy, and freeing up our internal teams to focus on higher-value projects. The automation and reliability Fonoa provides have made a big difference in simplifying our overall tax operations. ### 8. Review from the Client Project Manager’s Perspective **Rating:** 4.5/5.0 stars **Reviewed by:** Paula C. | Project Manager, Enterprise (> 1000 emp.) **Reviewed Date:** July 24, 2025 **What do you like best about Fonoa?** What I’d like to highlight about Fonoa, first from a team quality perspective, is their consistently positive attitude. They’ve always been open to constructive communication and have provided solid support as a vendor — making collaboration with Fonoa genuinely pleasant. I also value their agility and responsiveness. The team reacts quickly to issues and shows a flexible, solution-oriented mindset, which has been key to keeping momentum **What do you dislike about Fonoa?** One area of improvement for Fonoa, from my point of view, would be to ensure the agreed timelines are consistently met, in order to avoid delays. Additionally, providing closer support to local and tax teams throughout the different project phases would be valuable — helping ensure full coverage of functionalities, trainings, and other key elements, so we can anticipate and minimize potential risks. **What problems is Fonoa solving and how is that benefiting you?** More than a problem, as an organization we are committed to Fonoa to have a single fiscalization provider and to centralize processes, thereby creating synergy between teams and consequently, greater efficiency. **Official Response from Aubrey Harper:** > Thanks for sharing your perspective, Paula. It's great to hear that the collaboration has felt positive and that our team’s responsiveness and mindset have helped keep things moving. We also really appreciate the feedback around timelines and local support during project phases. Those are important areas, and your input helps us continue to raise the bar. We're glad to be part of your journey toward greater efficiency and centralized processes. ### 9. Comprehensive VAT software that ticks all the boxes! **Rating:** 4.5/5.0 stars **Reviewed by:** Chris A. | Financial Accountant, Enterprise (> 1000 emp.) **Reviewed Date:** July 17, 2025 **What do you like best about Fonoa?** The GITC VAT return software is very comprehensive and can handle our complicated VAT set up to include multiple entities within a VAT Group, partial exemption calculations, annual adjustments, reverse charge VAT etc. It has a detailed reporting suite that shows us a summary of VAT incurred and charged for the quarter that helps us analyse our income and expenditure. Their customer service is also extremely helpful. **What do you dislike about Fonoa?** Some of the menus and dashboard layouts can be a bit confusing for new users, but once you get used to them they're easy to use. I'd also like to be able to reset my password myself via a link on the log in page, rather than having to email the helpdesk and wait for a response. **What problems is Fonoa solving and how is that benefiting you?** Since Making Tax Digital (MTD) was introduced around 5-6 years ago we needed software that was linked to our Finance System and could handle multiple complex data sets, in order to produce a 9 box VAT return and submit to HMRC. Fonoa's GITC software does all this for us. **Official Response from Aubrey Harper:** > Thanks for the detailed feedback, Chris. It's great to hear that the GITC VAT software is handling your complex setup effectively and that the reporting features and support have been valuable. We appreciate the notes on usability and self-service options. Improving the user experience is a priority, and feedback like yours helps guide where we focus next. ### 10. e-Invoicing product through Fonoa **Rating:** 5.0/5.0 stars **Reviewed by:** Jakub M. | Product Lead, Mid-Market (51-1000 emp.) **Reviewed Date:** July 07, 2025 **What do you like best about Fonoa?** There are several key aspects I would like to highlight regarding Fonoa: Advanced API Design: The technology features a highly sophisticated API design, which facilitates straightforward and efficient integration. Intuitive User Interface and API: Both the user interface and the API are intuitive, contributing to a seamless user experience. Responsive Customer Support: The Customer Support Team responds promptly to reported issues and proactively communicates any changes or issues they observe. Expanding Country Coverage: The platform’s country coverage is continuously being expanded. **What do you dislike about Fonoa?** Areas for improvement Enhanced User Interface Functionality: The user interface would benefit from the addition of further features to better support diverse user needs and workflows. Comprehensive Business Case Coverage: While certain business cases are not yet fully addressed, the team diligently records all feedback and insights. They are actively working on implementing requested features in a timely and efficient manner. **What problems is Fonoa solving and how is that benefiting you?** e-invoicing is allowing our product to be compliant in crucial jurisdictions where our clients operate **Official Response from Aubrey Harper:** > Really appreciate you taking the time to share this. It's great to hear the API design, UI, and support have all contributed to a solid experience so far. And you're right—the expanding country coverage is something we're excited about too. Thanks as well for the constructive feedback. Adding more depth to the UI and covering more complex business cases are both important goals for us, and your input helps guide where we go next. We're glad to be building this with you. ### 11. Developer and User friendly, the best of both worlds **Rating:** 5.0/5.0 stars **Reviewed by:** Alexander M. | Software Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** July 03, 2025 **What do you like best about Fonoa?** From start to finish, integrating with Fonoa was significantly less painful than with other providers. We received a ton of support from start to finish and the documentation was well structured and easy to follow. The Fonoa team constantly checked in to see how we were doing and to make sure that no issues arose. Since integrating, we have been very happy with both the performance of Fonoa and the support. **What do you dislike about Fonoa?** My only complaint would be some minor bugs we faced with validations and the UI. These were resolved rather quickly however, but at the time it was a little frustrating. **What problems is Fonoa solving and how is that benefiting you?** Fonoa is helping us e-invoice at scale. We do not need to concern ourselves with the deeper reporting implications of expanding operations to new countries, as we simply have to extend the same code we wrote for any other country Fonoa supports. This saves us an immense amount of time, since ~90% of the work is easily transferrable, while the other 10% can vary between countries. **Official Response from Aubrey Harper:** > Thanks for sharing your experience. It’s great to hear the integration went smoothly and that the documentation and support helped make things easier along the way. Appreciate you calling out the early bugs too—glad we could resolve them quickly, but we know even small hiccups can be frustrating in the moment so we hope to learn from them always. Really happy to hear that invoicing at scale is now more manageable for your team. That kind of flexibility and time savings is exactly what we aim to deliver. ### 12. Great Support and Seamless Integration **Rating:** 4.5/5.0 stars **Reviewed by:** Omar Q. | VAT analyst, Enterprise (> 1000 emp.) **Reviewed Date:** July 02, 2025 **What do you like best about Fonoa?** What I liked best about Fonoa was how intuitive and easy the tool was to use from day one. The user interface is clean, modern, and well-organized, which made navigating and managing tasks straightforward and efficient. Additionally, the team behind the product was fantastic to work with—always responsive, knowledgeable, and genuinely committed to helping us succeed. Their support made the entire experience smooth and enjoyable. **What do you dislike about Fonoa?** There’s nothing I particularly dislike about Fonoa at the moment. Like with any software, minor hiccups do occur occasionally, but they’re typically addressed and resolved promptly by the support team, which makes a big difference. **What problems is Fonoa solving and how is that benefiting you?** Fonoa is helping us streamline EU VAT number validation, which used to be a time-consuming and error-prone process. Their tool integrates seamlessly into our workflow and ensures that validations are accurate and efficient. This has significantly improved our compliance processes and saved our team valuable time. **Official Response from Aubrey Harper:** > Really appreciate you sharing this. It’s great to hear Lookup felt easy to use from day one and that integration has been smooth. Also delighted to hear the shoutout to the support team, we'll definitely pass along. They put a lot into making things feel simple and seamless, so we're very happy to hear it’s coming through on your side. Sounds like VAT validation is running more efficiently now and saving your team valuable time—that's what we aim for! ### 13. Fonoa’s suite of tax automation services **Rating:** 5.0/5.0 stars **Reviewed by:** Niranjan B. | Project Manager, Enterprise (> 1000 emp.) **Reviewed Date:** August 08, 2025 **What do you like best about Fonoa?** We’ve been using Fonoa’s suite of tax automation services — including the Tax Engine, TIN Validation, Booking Report Transaction, and Fetch Invoice services — and our experience so far has been very positive. Very easy to use and implement their developer friendly services. Exception customer support and timey response. The documentation helps in quick and easy integration f their services. Overall very happy with their services. **What do you dislike about Fonoa?** All good so far. There have been some outages but the TAT was pretty quick with agreed SLOs. **What problems is Fonoa solving and how is that benefiting you?** Fonoa is helping us solve two critical tax compliance challenges: accurate tax ID (TIN) validation and real-time tax calculation across multiple jurisdictions. With TIN validation, we’re able to verify taxpayer identities across numerous countries using official databases. This ensures we collect valid tax IDs during onboarding or invoicing, reducing the risk of VAT exposure, non-compliance, and audit penalties. It also supports DAC7 and similar regulatory frameworks, enabling us to operate confidently in regulated markets. The Tax Engine provides real-time, automated tax calculations for VAT, GST, and sales tax. It factors in location, thresholds, exemptions, and business-specific rules, helping us apply the correct tax treatment on every transaction. This has eliminated the need for manual tax logic and reduced the risk of incorrect tax rates being charged or missed. Together, these services have improved our tax accuracy, reduced compliance risk, and accelerated our ability to scale into new markets—while saving time and effort for our internal teams. **Official Response from Aubrey Harper:** > Hi Niranjan, thanks for sharing your experience. We’re so happy to hear the services have been easy to work with, well-documented, and backed by a team that’s there when you need us. It’s also great to know the quick turnaround during outages has been felt on your side. We’ll keep building on that reliability while making sure the tools continue to help you stay compliant and grow with confidence. Looking forward to continue partnering together. ### 14. Focuses on authenticity of user experiences **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Leisure, Travel & Tourism | Enterprise (> 1000 emp.) **Reviewed Date:** July 30, 2025 **What do you like best about Fonoa?** We have been working with Fonoa to integrate their invoice generation and report transaction APIs for various tax authorities. One of the things we appreciate most about Fonoa is the comprehensive set of APIs they provide, which makes it straightforward to comply with the specific requirements of each country. The documentation is clear, and the integration process is smooth. Fonoa’s support team stands out for their responsiveness and expertise. Whenever we encounter issues or have questions, they are quick to assist and provide effective solutions. Additionally, when we have new onboarding requirements for additional countries, Fonoa is proactive in guiding us through the process and ensuring everything is set up correctly. Overall, Fonoa has been a reliable partner, helping us streamline our invoicing processes across multiple jurisdictions and making it much easier to stay compliant with local tax regulations. **What do you dislike about Fonoa?** While our overall experience has been very positive, there is certain area where we see room for improvement. As the platform continues to expand to new countries, there can be a learning curve with understanding the nuances of each integration. Recently Fonoa has shared about upgrade of their architecture which will improve the efficiency of new country onboarding. It is a very positive decision being made, we look forward to continuing our collaboration and seeing further enhancements to the platform. **What problems is Fonoa solving and how is that benefiting you?** Fonoa is addressing a significant challenge for businesses operating internationally: the complexity of complying with diverse tax regulations and electronic invoicing requirements across different countries. Each jurisdiction, such as Spain, Portugal, and Hungary, has its own specific rules and technical standards, which can make integration and ongoing compliance both time-consuming and resource-intensive. By providing a unified set of APIs for invoice generation and tax compliance, Fonoa streamlines this process for us. Instead of building and maintaining separate solutions for each country, we can rely on Fonoa’s platform to handle the technical and regulatory differences. This not only saves us considerable development effort but also reduces the risk of errors and non-compliance. Another major benefit is the support Fonoa offers. Their team is responsive and knowledgeable, helping us quickly resolve any issues and guiding us through onboarding for new countries. This partnership allows us to expand our operations more confidently and efficiently, knowing that we have a reliable solution in place for our invoicing and tax compliance needs. **Official Response from Aubrey Harper:** > Thanks for the detailed feedback. It’s great to hear the APIs and documentation have made integration straightforward, and that the support team has been a strong partner throughout. You’re absolutely right that every new country brings its own complexity, and we appreciate your patience as we continue scaling. The architecture upgrades we're planning are just one step toward making onboarding smoother, and we’re excited to keep improving that experience alongside you. ### 15. Fonoa has put the right foot forward **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Online Media | Enterprise (> 1000 emp.) **Reviewed Date:** July 29, 2025 **What do you like best about Fonoa?** I think many businesses will come to realise that Fonoa has several great propositions that can help meet the requirements legislated for both now in the coming months and years. We use their solution for e-invoicing and TIN Validation. E-Invoicing Thoughts: The API solution is a great way of ensuring that you can have a consistent data set across multiple countries to be compliant with e-invoicing that is consistent across each country - something that I know competitors were slow to catch up to from previous experience. The documentation that Fonoa has available over and above their online API is also helpful and should you have any issues their support team is on hand to help. If you want to make use of the API endpoints, it will either require some technical experience or involvement with the IT team. However, once it is implemented and up and running it is easy to use and capable of being used seamlessly. TIN Lookup With the arrival of DAC7 and a requirement to undertake due diligence on all customers, Fonoa's API driven solution to TIN lookup across a multi-jurisdiction single platform is pretty unique and makes our customer onboarding solution much easier to handle. Fonoa has a strong capable team and its support model is only getting stronger. I would strongly recommend them. **What do you dislike about Fonoa?** I sometimes think they can be too quick out of the gate to try and corner the market. The DAC7 software to produce a compliant DAC7 file was not polished enough for release in year 1, but they recognised this and sought to improve its capabilities in year 2. **What problems is Fonoa solving and how is that benefiting you?** Compliance driven by tax authorities is Fonoa's reason for existence and they are developing solutions that means this process is effortless. **Official Response from Aubrey Harper:** > Thanks for such a thoughtful review. It's great to hear that both our E-Invoicing and Lookup solutions have helped simplify compliance across multiple jurisdictions. We also appreciate your honest note about DAC7. We're glad you’ve seen how much progress has been made since our first iteration, and we're committed to building with long-term impact in mind. Feedback like yours helps us keep moving in the right direction, so thank you. ### 16. Reliable and Supportive E-Invoicing Solution with Promising Growth Potential **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Enterprise (> 1000 emp.) **Reviewed Date:** July 17, 2025 **What do you like best about Fonoa?** What I like best about Fonoa is the combination of a solid core product and an outstanding support team. The e-invoicing solution is well-suited for companies operating in major markets, with a strong focus on compliance and simplicity of integration. Their API is thoughtfully designed, and the documentation, although occasionally lacking in certain edge-case details, is generally clear and developer-friendly. What truly stands out is the responsiveness and dedication of the Fonoa team assigned to our integration. They are not only highly cooperative but also proactive in resolving issues and providing guidance, making the entire onboarding and implementation process much smoother. **What do you dislike about Fonoa?** While my overall experience with Fonoa has been positive, there are a few areas that could be improved. The product is still in its growth phase, which means some features, particularly those related to postpaid invoice handling, are either limited or not yet available. The platform is primarily designed with the prepaid model in mind, so adapting it to more complex postpaid workflows can require workarounds or additional support. Additionally, although the documentation is generally well-structured and helpful, it sometimes lacks deeper detail in more advanced or country-specific scenarios, which can slow down implementation. Another limitation is that Fonoa does not yet offer full coverage for all countries. While many key markets are supported, some jurisdictions are still pending implementation. This appears to be due to a roadmap that prioritizes features based on the needs of major clients, a perfectly understandable approach, but one that may affect companies operating in less common or emerging markets. That said, the impression I’ve gotten is that Fonoa is genuinely committed to achieving global coverage, and their team is actively working toward that goal. **What problems is Fonoa solving and how is that benefiting you?** As a global company operating across many jurisdictions, our primary challenge has been maintaining compliance with constantly evolving local e-invoicing regulations. Invoicing and regulatory compliance are not our core competencies, so we needed a reliable partner to help bridge that gap and ensure our systems meet each country’s legal requirements. Fonoa is helping us solve exactly that. Their solution acts as a central integration layer between our invoicing systems and the various government platforms, allowing us to offload the complexity of managing country-specific compliance rules. This greatly reduces our internal effort, risk of non-compliance, and the time we would otherwise spend keeping up with regulatory changes. Their focus on seamless integration and strong support makes it easier for us to scale and expand to new markets with confidence. **Official Response from Aubrey Harper:** > Thanks so much for sharing this. We're really glad the combination of a strong core product and hands-on support made your onboarding and implementation experience smoother. Appreciate the thoughtful feedback around postpaid handling, documentation depth, and country coverage as well. You’re absolutely right, this is a growing platform, and your insights help shape how we prioritize and evolve. We’re committed to building a product that scales with our customers, and it means a lot to know you see the potential in that journey. ### 17. Promp and proactive **Rating:** 4.5/5.0 stars **Reviewed by:** Alina N. | EMEA lead and Budget lead for Women in Green, Enterprise (> 1000 emp.) **Reviewed Date:** July 02, 2025 **What do you like best about Fonoa?** Working with Ralph van Coevorden, in this capacity of Head of Solution Architects, gave me the best experience. He is always very prompt and also with a "can do" attitude. The best part is that he is actually doing it in a very efficient way. From implementations to easiness that it makes it look like. I am working with Fonoa for the past 3 years and i will continue doing it **What do you dislike about Fonoa?** i do not have a thing in particular up to this moment **What problems is Fonoa solving and how is that benefiting you?** we are using the VAT number check integrated in our ERP and gives us the comfort of correct data when applying for VAT exemptions or VAT deduction of the input VAT **Official Response from Aubrey Harper:** > Thank you for the kind words and for being with us these past three years. We’re so glad Ralph’s support has made a real impact for you. He’s great at turning complex things into simple, smooth experiences (though we might be a bit biased 😄).

A standout vendor for Global tax compliance – Great tech and even better people **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Enterprise (> 1000 emp.) **Reviewed Date:** July 03, 2025 **What do you like best about Fonoa?** What really sets Fonoa apart is their incredible global coverage and how fast they’re scaling their offering : from tax ID validation to tax determination, e-invoicing and e-reporting... For us, using their tax ID validation tool has brought peace of mind around VAT compliance in jurisdictions where rules are particularly strict for non-resident digital service providers. Equally important, the experience with their technical team and account executive has been excellent , highly knowledgeable, responsive, and proactive. You don’t often come across vendors who combine solid tech with such a strong service mindset. Big kudos to Phil Reid , David Pevec! **What do you dislike about Fonoa?** It's not so much a dislike, but a wish to see further expansion in the future. Specifically, it would be great to have tax ID validation for Canadian provinces and for Fonoa to implement Philippines tax ID validation as soon as possible to comply with the new non-resident VAT mandate there. We believe these enhancements would make Fonoa an even more complete solution for global compliance. **What problems is Fonoa solving and how is that benefiting you?** Fonoa is helping us address a critical compliance challenge: validating customer tax IDs across multiple jurisdictions where we operate under non-resident VAT rules. With the global shift toward digital VAT enforcement, especially for B2C transactions, ensuring tax ID accuracy is essential for charging tax correctly and avoiding unnecessary exposure or audit risks. Their tool allows us to automate this validation process at scale, reducing manual workload and increasing confidence in our tax determination logic. This directly supports our ability to remain compliant, efficient, and audit-ready as we expand globally. **Official Response from Aubrey Harper:** > Thanks for sharing such thoughtful feedback. It means a lot to hear that our global coverage and scaling efforts are making a real difference for your team. We’re especially happy to hear your experience with Phil and David has stood out. They bring a lot of care and expertise to their work, and it’s great to see that reflected. We also really appreciate the input on future coverage. We love hearing that you want to use us in even more regions, and feedback like this helps us prioritize where to go next. We're aligned on what it takes to build a truly global solution. Thanks again for the partnership. We’re excited to keep building alongside you. ### 19. Fonoa as an enabler for growing invoicing requirements **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Enterprise (> 1000 emp.) **Reviewed Date:** July 17, 2025 **What do you like best about Fonoa?** The best thing about Fonoa is certainly the concept of integration, especially when portfolio consists of dozens of companies in different countries (globally!), with different requirements and e-invoicing specifics. This is one of the reasons why we chose Fonoa, to avoid investing significant internal resources in both development and maintenance. **What do you dislike about Fonoa?** Since e-invoicing requirements are accelerating recently, in combination with some specifics of customer portfolio, it might cause some hiccups in the implementation phase. This is something to be considered more carefully in the analysis phase from both Fonoa and customer side, to make implementation even smoother. However, Customer support is responsive and solutions are provided in the acceptable period of time. **What problems is Fonoa solving and how is that benefiting you?** Managing e-invoicing requirements globally, decreases investment of internal resources, minimizes the risk of non compliance. **Official Response from Aubrey Harper:** > Thanks for sharing this. It's great to hear that the integration model has helped you manage invoicing needs across a complex global portfolio without placing extra burden on internal teams. We appreciate the note on implementation challenges and agree that early alignment during the analysis phase is key to a smoother rollout. Glad to hear support has been responsive when it counts. Looking forward to continuing the work together. ### 20.
