Lexware Office (lexoffice) vs Tax Rex ‑ Sales Tax Automationfor Shopify (2026)
Lexware Office (formerly lexoffice) and Tax Rex - Sales Tax Automation are both Shopify apps in the Finances category, but they address different accounting needs. Lexware Office focuses on comprehensive accounting, primarily catering to European businesses requiring automated invoice creation, payment synchronization, and VAT compliance (including OSS). It aims to streamline the entire bookkeeping process, integrating directly with Shopify orders and various payment gateways. In contrast, Tax Rex specializes in US sales tax automation, providing tools for generating accurate reports, timely filings, and managing economic nexus across US states. It’s targeted towards businesses selling in the US market that need assistance with sales tax compliance. Lexware Office is an all-encompassing solution, handling invoice generation, payment processing integration, and various accounting needs related to tax declarations, and GoBD-compliance. Tax Rex is specific to the US market and addresses only the complex needs of sales tax collection, reporting, and filing. While Lexware Office automates processes for VAT returns (in Europe), Tax Rex provides a solution to navigate the various state tax rules of the US. Businesses using marketplace such as Amazon or Ebay can ignore those sales when using Tax Rex which is another advantage for some merchants.

Our Verdict
For Shopify merchants operating primarily in Europe and needing a comprehensive accounting solution covering invoicing, payment synchronization, and VAT compliance, Lexware Office is the better choice. Its features extend beyond basic tax reporting, offering a full-fledged accounting platform. However, if a merchant's primary concern is navigating the complexities of US sales tax, including nexus management and filing requirements, then Tax Rex ‑ Sales Tax Automation is the superior option. Its specialized features cater specifically to the nuances of US sales tax laws. The higher rating of Tax Rex, despite fewer reviews, suggests higher customer satisfaction regarding sales tax automation specifically.
Common Questions
Which app is easier to set up?

Can Lexware Office handle US sales tax?
The description of Lexware Office primarily mentions features relevant to European VAT regulations and makes no specific claims about handling US sales tax. Therefore, it is not suitable for US sales tax compliance.
Does Tax Rex integrate with accounting software?
The provided description for Tax Rex focuses solely on US sales tax reporting and filing. It does not mention integration with broader accounting software packages.
Which app offers better value for money for a small business?
Value for money depends on the specific needs. If the business requires a full accounting solution with European VAT compliance, Lexware Office offers more comprehensive functionality. If the business only needs help with US sales tax, Tax Rex is likely more cost-effective.
Can I use both apps together?
