"Zamp Makes Sales Tax Easy"
5/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

"Effortless Tax Compliance and Peace of Mind"
5/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

"Responsive, Expert Support for State Sales Tax and Reporting"
4.5/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

"Efficient Tax Management with Stellar Support"
4/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

"Effortless Tax Management with Excellent Support"
5/5
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. Review collected by and hosted on G2.com.

"Efficient Tax Compliance with Great Support"
4/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

"Streamlined Our Sales Tax Management with Exceptional Support"
4.5/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

"Best Sales Tax Agency!"
5/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

"Zamp Took Sales Tax Off Our Plate Completely"
5/5
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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.
