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.

Tax Rex has been a HUGE help in determining sales tax obligation with the 'Economic Nexus' laws. The app is very simple to use, have very clear reports for filing and is very inexpensive to use given the amount of time we save in reporting tax across several states.

Given the very limited Shopify Tax for non-Plus stores, this is a must have to streamline the tax back-end and stay in compliance.

Excellent app, excellent value and truly excellent and quick support!!
