Zamp is a dream as a customer. We’re a subscription dog food brand selling in every state, and they handle all of our sales tax registrations and filings so it’s completely off my plate. The team is fast, detail-oriented, and follows up at exactly the right cadence, so nothing slips through the cracks. Even the automated emails are genuinely useful, and when you reply you always get a real, capable person. Way easier to use than Avalara. Highly recommend for any Shopify brand.
The folks at Zamp have been great to work with! Helped us understand how sales tax works and their processes allow us to be almost completely hands off when it comes to registrations & remittances per state. Very easy onboarding process and the support staff are very responsive. Highly recommend!
