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.

Worry-free compliance, amazing technology checked by super knowledgable human experts, great customer service,

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.
