Very responsive team and easy to work with. This app has helped manage and simplify our monthly sales tax requirements immensely.

I don't know why I was trying to do it on my own. We operate in a single state (California) and their tax filings are horrible. Shopify tax was difficult to manually process, and their automated filings worked but wouldn't allow for companies that have to remit monthly tax filings. Tax Rex to the rescue! We are new with them, but communication is great and looks like we are good to go. What was a 1/2 day process trying to sort through reports is now automatic. Thank You!

Tax Rex has been a huge help for our Shopify store. The app itself works exactly as needed, but what really stands out is the customer service. Their team is incredibly patient, responsive, and thorough. Every question we’ve had — even the small, technical ones — has been handled quickly and clearly. They take the time to explain things in a way that actually makes sense, which is rare when dealing with tax-related tools. It’s clear they care about getting it right, not just closing tickets. Highly recommend if you’re looking for a reliable solution backed by a truly supportive team.
