Our Verdict
For US-based Shopify merchants primarily concerned with US state sales tax compliance, especially those struggling with economic nexus and filing requirements, Tax Rex ‑ Sales Tax Automation is the clear choice. Its focused features address these pain points directly. However, if a merchant is already using Xero for accounting and needs a seamless integration between their Shopify store(s) and Xero, especially if they sell internationally and deal with multiple tax jurisdictions, Xero Connector by CarryTheOne is the more appropriate solution. Choosing the right tool depends on the merchant's specific needs and existing accounting infrastructure.
Common Questions
Does Tax Rex integrate with Xero?
The provided information does not state that Tax Rex integrates with Xero. It focuses on sales tax reporting and filing.
Can Xero Connector handle US sales tax?
Yes, Xero Connector supports US sales tax, including county and municipal levels. However, it doesn't provide the same level of automation for filing as Tax Rex.
Which app is easier to set up?
Without user reviews specifically addressing ease of setup, it's difficult to say definitively. Tax Rex's focus on a single task (sales tax) might suggest a simpler setup process compared to the broader accounting integration of Xero Connector. However, Xero connector is reported to have been around for 15 years suggesting maturity in their setup process.
Which app is better for a small business?
If the small business is only selling within the US and struggles with US sales tax, Tax Rex is likely the better choice. If they already use Xero and need an integration, Xero Connector is better. The better fit is heavily dependent on the existing tools and needs of the business.
Does Tax Rex support Canadian sales tax (GST/HST)?
No, Tax Rex is focused on US state sales tax. For Canadian sales tax support, Xero Connector is the better option.
