MamaSuds review for Tax Rex ‑ Sales Tax Automation

Feb. 12, 2026

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.
