Our Verdict
Tax Rex is the clear choice for US e-commerce merchants seeking to automate sales tax compliance and reduce the risk of errors and penalties.

Unique Transactions Code is suitable only for a very specific niche: merchants who still rely on manual bank transfers and need a simple way to track payments. Most Shopify merchants will not need its functionality. Tax Rex delivers more value for a far larger user base.
