Our Verdict
Both Sidr and Tax Rex offer comprehensive solutions for sales tax automation, catering to Shopify merchants needing help with compliance. Sidr might be preferred by merchants who value a US-based company with direct chat and email support and are willing to prioritize that aspect. Tax Rex, with more reviews and the ability to exclude marketplace orders, could be a better choice for merchants with a diverse sales channel strategy that includes platforms like Amazon and eBay, and for whom number of reviews is an indicator of trust and robust functionality. The choice ultimately depends on whether marketplace order exclusion and a larger user base are crucial versus prioritizing USA-based service and direct chat support.
