Phenomenal, Responsive Support That Simplifies Taxes **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Construction | Small-Business (50 or fewer emp.) **Reviewed Date:** January 30, 2026 **What do you like best about Zamp?** The customer service is phenomenal!! Caroline Cassell is extremely responsive, knowledgeable, patient, and professional. Before acquiring ZAMP services, I was apprehensive about our taxes and realized I needed a professional to assist me. In the few months I have worked with ZAMP and Caroline, my concerns have been eased and I am much more confident in our filings, etc. I am very impressed with ZAMP's tax knowledge and expertise, and I am very grateful they can simplify it for those of us who are less proficient. I am delighted to be working with ZAMP!! **What do you dislike about Zamp?** I absolutely have no dislikes about Zamp. They are a perfect service to meet my needs. **What problems is Zamp solving and how is that benefiting you?** ZAMP is handling our sales & use tax filings, and they are monitoring to determine nexus. When determined, they establish / register on our behalf. Also, ZAMP handles all communications that relate to the taxes handled on our behalf. ### 3. Zamp Has Tremendous value and Service **Rating:** 5.0/5.0 stars **Reviewed by:** Mark P. | Owner/Founder, Small-Business (50 or fewer emp.) **Reviewed Date:** January 22, 2026 **What do you like best about Zamp?** My controller's due diligence chose Zamp as our sales tax platform. I trusted her analysis and we onboarded. We were pleasantly surprised at the service and competency of Zamp. Everything went smoothly. Registrations, filings, accounting. Then I sold my business. It was time for me to de-register all the accounts that had been created by Zamp. The process seemed difficult as each state had a different system and all the logon 2FA emails were going back to Zamp. I called the published number. I did not wait and was not put on hold. I was connected to an excellent technician who walked me through the process, state by state. It was a long call, and she was never in a hurry. We deregistered all but one of the accounts. The next day I got an email confirmation that she had gone ahead and figured out the last state de-registration. This was not service to GET my business. This was service to help me END my use of Zamp. (Luckily for Zamp, the new owners signed on because of our recommendation!). I'd rate them 11 out of 10. Rarely have I seen this level of service from a SaaS provider. Bravo! **What do you dislike about Zamp?** We didn’t see any real downside. Cost is always a consideration, but based on our calculations, Zamp ended up being more efficient than handling it ourselves. **What problems is Zamp solving and how is that benefiting you?** The state-by-state sales tax jungle is mind-numbing for a small business. Zamp makes it easy and onboarding was fast and efficient. ### 4. Streamlined State Tax Filings but Needs Automatic Approvals **Rating:** 3.5/5.0 stars **Reviewed by:** Will S. **Reviewed Date:** December 29, 2025 **What do you like best about Zamp?** I love that Zamp emails me for approvals before filing for each month or quarter depending on state requirements. It's useful because I can always ensure we have the correct amount of money available in our specific business checking account to cover the necessary sales taxes. The initial setup was easy. **What do you dislike about Zamp?** I think we could use an automatic approval system for approving sales tax in scenarios where we are unable or forget to approve specific months or quarters. Not currently. Looking into other sales tax companies due to the cost point - other companies seemingly can handle the sales tax for misc. states with less cost. It was easy, however it would have been nicer if Zamp handled direct mail too. **What problems is Zamp solving and how is that benefiting you?** Zamp solves the problem of figuring out where and how to file state sales tax. It sends email approvals before filing, ensuring I have enough money ready in my business account. ### 5. Supportive and Reliable Partner **Rating:** 5.0/5.0 stars **Reviewed by:** ANGIE L. | Controller, Small-Business (50 or fewer emp.) **Reviewed Date:** September 19, 2025 **What do you like best about Zamp?** Zamp has been extremely supportive throughout our sales tax process. From the start, Matt was very helpful in explaining the service clearly and guiding us in making the decision to work with Zamp. The onboarding process was smooth and efficient, and Carson, in particular, has always been quick to respond and willing to go the extra mile. Their team makes what could be a complicated area feel simple and manageable, and their responsiveness gives us confidence that we are in good hands. **What do you dislike about Zamp?** We truly appreciate their service and hope Zamp continues to keep up the excellent work! **What problems is Zamp solving and how is that benefiting you?** Our business operates in nearly all U.S. states, so sales tax registration and compliance could easily become overwhelming. One of the biggest benefits of Zamp is that registration is included in their package, which removes a major burden from our team and was a key reason we chose Zamp over Avalara. Having everything bundled together and handled by the same supportive team makes the process simple and efficient. Unlike Avalara, where responsibilities are split across different people and services, Zamp provides a streamlined, one-team experience that saves us time, reduces confusion, and gives us confidence that compliance is fully taken care of. ### 6. Zamp Makes Sales Tax Easy **Rating:** 5.0/5.0 stars **Reviewed by:** Ethan S. | Senior Director of Accounting, Small-Business (50 or fewer emp.) **Reviewed Date:** August 27, 2025 **What do you like best about Zamp?** We onboarded Zamp after canceling our renewal with Avalara, and were under a bit of a time crunch to make sure we didn't miss a filing deadline, and Zamp made the process easy as possible with daily calls to ensure that all of our i's were dotted and t's were crossed. Zamp is super responsive to questions and provides helpful context for any notices that we receive, most of which are already being taken care of. Zamp helps take the burden of sales tax off of my plate as a Controller of an e-commerce startup. **What do you dislike about Zamp?** I cannot think of any downsides to using Zamp. Managing sales tax is a tedious and burdensome task for any e-commerce company, especially startups with limited resources, and products like Avalara sometimes only make things more complicated. Zamp seems to have solved for that problem with a more personal touch and fast responsiveness. **What problems is Zamp solving and how is that benefiting you?** Filing Sales tax returns. ### 7. Effortless Tax Compliance and Peace of Mind **Rating:** 5.0/5.0 stars **Reviewed by:** Ana P. | Small-Business (50 or fewer emp.) **Reviewed Date:** October 27, 2023 **What do you like best about Zamp?** I love how Zamp provides us with peace of mind by taking charge of our sales tax registration in every state where we are qualified to pay. Their proactive approach ensures that we are always compliant and keeps us informed if we need to activate sa State on Shopify. They manage the complex task of paying our sales taxes, a process that was previously cumbersome and annoying for our small company. What I appreciate most is their large, experienced team and fast responses to our questions. It's comforting to know that knowledgeable professionals are handling our financial operations, ensuring nothing critical is overlooked that could impact our business. The ease of setup with Zamp was impressive as they guided us through smoothly, making the transition effortless. **What do you dislike about Zamp?** I sometimes find it challenging when making changes related to company statuses, especially when we recently updated our company title from LLC to incorporated. There are certain changes that Zamp couldn't handle because these require the company itself to make the modifications directly. This limitation seems to be dependent on state regulations, which appears to restrict companies like Zamp from executing such changes for us. **What problems is Zamp solving and how is that benefiting you?** I use Zamp to handle sales tax payments, registration in multiple states, and ensure compliance, saving us time and relieving the burden of managing tax processes as a small company. ### 8. Responsive, Expert Support for State Sales Tax and Reporting **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Computer Games | Mid-Market (51-1000 emp.) **Reviewed Date:** March 04, 2026 **What do you like best about Zamp?** Zamp is responsive whenever we have questions about state sales tax issues. They support us with sales tax reporting, and their deliverables are consistently punctual and handled with expertise. **What do you dislike about Zamp?** Zamp asks us to provide the information needed for tax reporting as early as one month before the reporting deadline. Sometimes that information simply can’t be provided that far in advance, so the process doesn’t feel very flexible. **What problems is Zamp solving and how is that benefiting you?** Zamp helped us audit the closure of our sales tax accounts across various states. They provided complete clarity and confirmation that all of our sales tax accounts had been closed. Zamp also supported us with Washington B&O tax reporting and settlement. As a result, we feel relieved of much of the administrative burden involved in tax reporting and settlement. ### 9. Efficient Tax Management with Stellar Support **Rating:** 4.0/5.0 stars **Reviewed by:** Jessica O. **Reviewed Date:** October 26, 2025 **What do you like best about Zamp?** I have been using Zamp for our newly established US entity and have found it incredibly helpful for preparing and submitting state tax returns, especially given that our finance team is based in another country. The setup process was very straightforward, involving quick contract and costing discussions, and the portal integrated well with our e-commerce platform, Big Commerce. I particularly appreciate Zamp's ability to calculate county-specific taxes and provide live tracking of nexus and reporting obligations, which are crucial for our operations. The service has significantly saved time for my team in calculating and reporting sales tax, which justifies the investment in Zamp. Furthermore, the team at Zamp is outstanding, always providing excellent support and troubleshooting any issues that arise effectively. **What do you dislike about Zamp?** I occasionally experience integration issues with Zamp but the team is very helpful and has fixed the problems. It would be beneficial if integrations were more seamless to enhance overall usability. **What problems is Zamp solving and how is that benefiting you?** Zamp simplifies tax calculations and reporting for my new US entity, saving my team significant time and helping manage county-specific taxation and nexus obligations effectively. ### 10. Effortless Tax Management with Excellent Support **Rating:** 5.0/5.0 stars **Reviewed by:** Geoffrey C. **Reviewed Date:** October 22, 2025 **What do you like best about Zamp?** I found the setup process for Zamp to be extremely easy. The onboarding team provided a step-by-step guide and followed up on action items, ensuring a smooth transition to becoming a client. Zamp effectively solves the problem of filing state sales tax across multiple states, saving us significant time compared to monitoring and setting up each state separately. This efficiency has been a major benefit for our team. I find Zamp's ability to track and file state sales taxes, whether monthly, quarterly, or semiannually, particularly useful. The ease of use and the supportive team behind the scenes make the experience positive. Additionally, the cost of the service is very reasonable, adding to its attractiveness. My overall satisfaction is reflected in my high likelihood to recommend Zamp, giving it a perfect score of 10. **What do you dislike about Zamp?** Nothing, Zamp met all of our needs. **What problems is Zamp solving and how is that benefiting you?** I use Zamp for filing state sales tax across multiple states, saving time by avoiding manual monitoring and setup for each state. ### 11. Efficient Tax Compliance with Great Support **Rating:** 4.0/5.0 stars **Reviewed by:** Niccola G. **Reviewed Date:** October 21, 2025 **What do you like best about Zamp?** I find zamp valuable in keeping us compliant with state taxes and ensuring that we are aware of our nexus status, which is crucial for our business operations. The online system is easy to access and allows me to view past filings per state, providing a great way to cross-reference information from multiple sources like Shopify. The integration with platforms like Shopify and Amazon has been seamless, which simplifies our workflow considerably. Furthermore, the major advantage for me is the ability to reach out and communicate with a real person anytime something goes wrong, without having to rely solely on submitting support tickets. This access to prompt, personalized customer support makes solving any issue quick and direct, which I really appreciate. The straightforward setup process, despite some initial hurdles with double-factor authentication, was manageable, and efficiently importing data from previous vendors made the transition to zamp hassle-free. **What do you dislike about Zamp?** I find that Zamp is limited to handling only sales tax. It would be beneficial if it also covered other areas like entity tax or excise tax. Right now, it's focused narrowly on sales tax services, which limits its full utility for users who may need a broader range of tax-related services. **What problems is Zamp solving and how is that benefiting you?** I use Zamp to stay compliant with sales tax, track our nexus, and get notified of registration needs, benefiting us by ensuring timely tax payments and avoiding compliance issues. ### 12. Streamlined Our Sales Tax Management with Exceptional Support **Rating:** 4.5/5.0 stars **Reviewed by:** Kate S. **Reviewed Date:** October 21, 2025 **What do you like best about Zamp?** I love that Zamp has streamlined the sales tax process for our ecommerce business, turning it into a 'set it and forget it' system. Their quick monthly emails for review simplify our operations, allowing me to spot-check a few states before approving their plans for filing and remittance. The pricing structure is another highlight, providing a tiered system based on the number of states, which simplifies budgeting compared to our previous provider, TaxJar. I also appreciate their customer service immensely; they are incredibly responsive, often replying to my queries within the same day. This makes Zamp feel very supportive and attentive to our needs. Furthermore, their willingness to work with us on pricing for renewal, despite our initial thoughts of exploring cheaper alternatives, demonstrates their commitment to customer satisfaction. Finally, their reliability in filing and resolving any issues quickly makes me feel confident in their service, which is why I strongly recommend them. **What do you dislike about Zamp?** I can't really think of anything! **What problems is Zamp solving and how is that benefiting you?** I find Zamp simplifies sales tax handling, making it a set-and-forget process. Monthly emails allow easy reviews, and their tiered pricing is clear and beneficial. Their service saves time from manual state registrations, and their customer support is incredibly responsive. ### 13. CEO & Founder **Rating:** 4.5/5.0 stars **Reviewed by:** Sam C. | CEO & Founder, Small-Business (50 or fewer emp.) **Reviewed Date:** October 15, 2025 **What do you like best about Zamp?** What I appreciate most about Zamp is how hands-off it is. It’s super automated and just takes the guesswork out of everything. We’re not sitting around trying to figure out how much we owe or scrambling to file - they just handle it. **What do you dislike about Zamp?** What I dislike about Zamp is that they continue to email us about which date to apply the payments, even though by now they should be familiar with the appropriate dates. It feels repetitive, as we've already gone through this process multiple times. Another point of frustration is that the state filing letters are still sent directly to us instead of to Zamp, and setting things up with each jurisdiction can be somewhat cumbersome and frustrating. But overall, I would still rate Zamp a 9 out of 10. **What problems is Zamp solving and how is that benefiting you?** Zamp has eliminated the major hassle of handling sales tax in multiple states. Before, we were always scrambling to determine what needed to be filed, when it was due, and in which state, making the whole process feel uncertain and overwhelming. Now, what was once a stressful and time-consuming task has become almost entirely hands-off. I no longer have to stress about missing deadlines or doing any calculations—everything is simply taken care of. ### 14. Best Sales Tax Agency! **Rating:** 5.0/5.0 stars **Reviewed by:** Chelsea V. | Chief Operating Officer, Small-Business (50 or fewer emp.) **Reviewed Date:** July 31, 2025 **What do you like best about Zamp?** Switching to Zamp from Avalara has been a game changer. The difference has been night and day—what used to be a constant source of stress and uncertainty is now a seamless, worry-free process. Their team has taken the headache out of sales and use tax compliance. We finally feel confident that our remittances are accurate and nexus reports are on point. The trust we have in Zamp has made all the difference, and we truly appreciate the clarity and peace of mind they’ve brought to our operations. **What do you dislike about Zamp?** One area for improvement is the lack of a native integration with Shopify for real-time sales tax calculations at checkout. It would be a huge value-add if Zamp could sync directly with our storefront to automate tax calculations on the front end, rather than relying solely on post-sale reporting or using another third party application. This would close the loop and make the experience even more seamless for both our team and our customers. **What problems is Zamp solving and how is that benefiting you?** Zamp is solving the complexity and uncertainty around sales and use tax compliance. From managing remittances to tracking evolving nexus obligations, they've taken a time-consuming, error-prone process off our plate and replaced it with a streamlined, accurate system we can trust. The visuals on the nexus dashboard are especially helpful—they make it easy to quickly understand where we have obligations and why. And the upcoming direct integration with QuickBooks Online (QBO) will be a major win, reducing manual steps and ensuring our records stay in sync with our filings. Overall, Zamp has brought confidence, clarity, and significant time savings to our tax process. ### 15. Zamp Took Sales Tax Off Our Plate Completely **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer Software | Small-Business (50 or fewer emp.) **Reviewed Date:** October 09, 2025 **What do you like best about Zamp?** Zamp takes the hassle out of sales tax by managing the entire process for you, from registration and nexus tracking to filing and remittance. Its smooth integration with Stripe means that self-serve customers from any state have taxes automatically withheld, filed, and remitted. With the addition of responsive human support, you can feel confident that your registrations, thresholds, and deadlines are always handled properly. **What do you dislike about Zamp?** Because Zamp fully manages compliance, you lose some visibility and flexibility — filings, dashboards, and reporting follow their flow, and expanding into new states can still trigger requirements needing your input. It’s also a premium service, so costs can feel high for low-exposure states, and you remain dependent on their responsiveness and accuracy. **What problems is Zamp solving and how is that benefiting you?** Zamp takes the entire sales tax burden off our plate by managing calculations, registrations, nexus tracking, filings, and remittances across every state where our customers buy through Stripe. What used to be a confusing, time-consuming, and risky process is now handled end-to-end with accuracy and responsiveness, giving us peace of mind. The biggest benefit is the time and focus we’ve gained back to grow the business instead of worrying about compliance. ### 16.

The ability to get in touch with a support member when needed is a breath of fresh air.

Being an international company and having a trusted team file, review and provide insight into all aspects of US Sales Tax is a relief for our small team to not have to manage on our own. ### 17.

They have spoken to me many times and it is not hard to get in touch with customer care at ZAMP. Their pricing is extremely fair. Sales tax compliance was getting VERY expensive and for my business and I needed to find a better solution. I was sick of calling and sick of never getting calls back from my previous sales tax automation provider. And to add insult to injury the previous sales tax automation provider went up on rates almost double. This is when I found ZAMP. I can honestly say they saved me tons of stress and the video meetings helped establish a good relationship. The onboarding experience was pretty great and implementation of adding different sales tax agencies was super easy. They have made business personable again! YEAH FOR ZAMP! Thank you Zamp for making it much easier to run my business! **What do you dislike about Zamp?** When I first signed up their online platform was not robust.

It's a little tricky to see multiple states deduct from the bank account vs. one simple debit, however that is a small thing vs. their great service. **What problems is Zamp solving and how is that benefiting you?** They are providing a white glove service for multi-state sales and use tax, which is a very cumbersome process. Christine has given top notch customer service. ### 25. Effortless Setup and Outstanding Support from Zamp **Rating:** 5.0/5.0 stars **Reviewed by:** Jonathan M. | Head of Finance, Small-Business (50 or fewer emp.) **Reviewed Date:** October 21, 2025 **What do you like best about Zamp?** Ease of setup. The Zamp team handled all of our registrations and the communication has been top notch. **What do you dislike about Zamp?** Very little.

A worry-free complete sales tax compliance package with the best customer service ever! **Rating:** 5.0/5.0 stars **Reviewed by:** Gilles M. | Founder and CEO, Information Technology and Services, Small-Business (50 or fewer emp.) **Reviewed Date:** April 06, 2025 **What do you like best about Zamp?** Sales Tax compliance is a complex issue, even more so if you have multiple sales channels. Zamp took full responsibility of the entire setup for all my channels. I was among the first to use their WooCommerce integration plugin. Although my product catalog is small, it uses advanced settings and Zamp was able to quickly enhance their plugin to make it work for me. Zamp's tax team also verified all the tax codes for my products and services. The entire team responds quickly to requests. The onboarding process was smooth and easy. Their complete managed service is flawless so far and saves me a significant amount of time managing and monitoring sales tax (filings, nexus, compliance). The clear and all-inclusive pricing model is also a big plus! **What do you dislike about Zamp?** Nothing to say here. My original hesitation was that Zamp is not as established as some of the "big guys" in the space. But I firmly believe that I made the right decision to work with Zamp. **What problems is Zamp solving and how is that benefiting you?** Worry-free sales tax compliance is what I was looking for, and what I got. ### 27. More than Software - Updated **Rating:** 5.0/5.0 stars **Reviewed by:** Aman A. | CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** July 19, 2024 **What do you like best about Zamp?** Our partenership is now 'years' mature - and the intensity of their support has not slowed. Typically a partner like this will ease up after the sale is closed, or the honeymoon phase is over - but they doubled down and have stayed strong through the entirety of our relationship. **What do you dislike about Zamp?** Help to decommission states where we may not need to file anymore. **What problems is Zamp solving and how is that benefiting you?** Zamp files our taxes, communicates with states, previews payments, adjusts as needed, and suggests opportunities for efficiency and change. ### 28. Great support and a transparent approach to pricing **Rating:** 5.0/5.0 stars **Reviewed by:** Marijan M. | Logistics & Operations Specialist, Small-Business (50 or fewer emp.) **Reviewed Date:** May 16, 2025 **What do you like best about Zamp?** What impressed me the most was how responsive and professional the team was — especially Amelia and Ashley, who handled our case. The communication was fast, clear, and friendly. They offered transparent pricing options tailored to our situation and helped us resolve everything smoothly. It felt like we were genuinely supported instead of just being another client in the system. **What do you dislike about Zamp?** There’s not much to dislike, but if I had to point something out — the pricing structure can feel a bit rigid until you actually talk to someone from the team. Luckily, once we engaged with their team, things were quickly clarified and resolved. **What problems is Zamp solving and how is that benefiting you?** Zamp is helping us streamline and automate sales tax compliance across multiple states without needing a dedicated internal tax team. It saves us hours of manual work, reduces the risk of errors or penalties, and gives us peace of mind knowing we’re staying compliant. The platform is easy to use and the support team is extremely responsive, which makes the entire experience smooth and reliable. ### 29.

I also really like their platform, which securely stores sales tax information relevant to our business. **What do you dislike about Zamp?** Zamp is expensive but I will say I do like that it's subscription pricing so it's a predictable cost. **What problems is Zamp solving and how is that benefiting you?** Zamp is a sales tax solution, so they handle sales tax processes for us such as determining nexus and submitting recurring filings. They give me time back in not having to worry about sales tax filings and they give me confidence that filings are being done correctly and that we're compliant for now and the future. ### 30. Worry-Free Compliance and Great Support **Rating:** 5.0/5.0 stars **Reviewed by:** Isabelle C. | VP of Operations & Finance, Small-Business (50 or fewer emp.) **Reviewed Date:** October 23, 2025 **What do you like best about Zamp?** Worry-free compliance, amazing technology checked by super knowledgable human experts, great customer service, **What do you dislike about Zamp?** Honestly nothing. We've been so happy with Zamp. **What problems is Zamp solving and how is that benefiting you?** They're automating sales tax remittance compliance for brands selling online, which is a wildly complex problem with different taxation requirements by product and sometimes zip code. They're staying up to date on filing requirements for all jurisdictions, and guranteeing all returns they file for their customers. ### 31. Exceptional Service **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Online Media | Small-Business (50 or fewer emp.) **Reviewed Date:** October 01, 2025 **What do you like best about Zamp?** I appreciate how easy it is to communicate with Zamp and how smoothly their interface connects with our account.

Unmatched Customer Service and a Breath of Fresh Air **Rating:** 5.0/5.0 stars **Reviewed by:** David W. | Founder and CEO, Small-Business (50 or fewer emp.) **Reviewed Date:** December 18, 2024 **What do you like best about Zamp?** Their customer service is second-to-none. They respond quickly, are personable, and domestically based. I appreciate their care and attention to detail. We used to be with "the big competitor" in the space, and they were awful, with terrible responsiveness and unhelpful customer support. It was the best switch my company could have made. Their onboarding team worked on my behalf to assist us. Honestly, I cannot say enough good things about them. They cleaned up the mess my last bookkeeper left, and they worked after hours to help. Integrating with Zamp was as straightforward as the competition. Additionally, I actually prefer their Quickbooks integration as the sales tax for Quickbooks invoices is calculated on the "sales tax" line and not a line in the invoice (as done by their competition). Their pricing is fair as well. SWITCH from the "big guys" to them. You will not regret it. **What do you dislike about Zamp?** Their platform is still growing, so there might be a few rough edges, but honestly, nothing worth fretting over. If there are rough edges, the team will assist manually. It has not been a problem for us at all. They do ratchet the speed of their API, but you would be needing to do hundreds of transactions a minute to run into issues. Please note: they do not support SST. We had to move from SST to "traditional" sales tax to use Zamp. **What problems is Zamp solving and how is that benefiting you?** Zamp's tax compliance package does just what I need, and when combined with their amazing support, you simply cannot beat them. They do everything companies that are much larger do, but provide better pricing and exceptional service. ### 33. Outstanding Service **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Retail | Small-Business (50 or fewer emp.) **Reviewed Date:** May 01, 2025 **What do you like best about Zamp?** ZAMP has been an outstanding partner for handling our sales tax filings nationwide.

I like best that I don't have to worry about these things anymore. **What do you dislike about Zamp?** I guess the cost?
