Our Verdict
For Shopify merchants needing an all-in-one solution to manage finances, inventory, and operations across multiple channels and locations, Dynamics 365 Business Central might be a valuable option if the relatively low rating can be addressed with updates and support. However, smaller businesses or those prioritizing ease of use and a dedicated sales tax solution will find Tax Rex a better fit. Tax Rex's focus on automated filing and nexus alerts caters directly to the challenges of US sales tax compliance, making it the more compelling choice for those specific needs. The considerably higher rating and larger number of reviews also suggests a more positive user experience.
