QuickBooks Sync by MyWorks vs Tax Rex ‑ Sales Tax Automationfor Shopify (2026)
QuickBooks Sync by MyWorks and Tax Rex are both Shopify apps in the Finances category, but they address distinct accounting needs. QuickBooks Sync by MyWorks focuses on comprehensive accounting integration between Shopify and QuickBooks Online (with another app for QuickBooks Desktop). It targets merchants seeking to automate their bookkeeping and ensure accurate financial data across platforms, offering features like bi-directional syncing of orders, inventory, and customer data. The value proposition centers on time savings and improved data accuracy for overall business management. Tax Rex, on the other hand, is laser-focused on US state sales tax compliance. It automates sales tax return reports, filing, and provides economic nexus alerts, catering to merchants who need help navigating the complexities of US sales tax regulations. Its value lies in simplifying compliance, preventing penalties, and saving time on tax-related tasks. The primary difference lies in their scope. QuickBooks Sync is a broad accounting automation tool, connecting Shopify to a complete accounting system. Tax Rex is a niche solution designed specifically for US sales tax management. A merchant would choose QuickBooks Sync if they needed to manage all aspects of their accounting within QuickBooks, while Tax Rex is the right choice for merchants primarily concerned with simplifying and automating their US sales tax compliance. Although Tax Rex generates reports based on Shopify taxes collected, it does not provide an overall bookkeeping function like QuickBooks Sync.

Our Verdict
For merchants who rely on QuickBooks for their accounting and need a seamless integration with Shopify, QuickBooks Sync by MyWorks is the clear choice. Its bi-directional syncing and comprehensive features will automate their bookkeeping and reduce manual data entry. The 1:1 setup calls offer personalized support, which is valuable for getting started.
However, if a merchant's main concern is navigating the complexities of US sales tax and ensuring compliance, Tax Rex is the more suitable option. Its features specifically address sales tax reporting, filing, and economic nexus monitoring, providing a focused solution for this particular challenge. While it relies on existing tax collections within Shopify, it automates the process of reporting and filing to various states, saving significant time and effort.
Common Questions
Can QuickBooks Sync handle sales tax?
QuickBooks Sync synchronizes sales data with QuickBooks, including sales tax collected in Shopify. However, it doesn't automate sales tax return filings.
Does Tax Rex integrate with QuickBooks?
Tax Rex focuses primarily on generating sales tax reports and filing returns. It does not directly integrate with QuickBooks for broader accounting purposes.
Which app is easier to set up?
QuickBooks Sync mentions 1:1 setup calls, suggesting a potentially more guided initial setup. Tax Rex does not explicitly mention dedicated setup support, but its focus on sales tax might imply a simpler initial configuration given its narrower functionality.
Which app is best for a small business owner with limited accounting knowledge?
Tax Rex, with its focus on sales tax compliance, might be initially less daunting for a small business owner with limited accounting knowledge. However, a business aiming for a full accounting solution may benefit more from setting up QuickBooks Sync for the long run.
What kind of business might prefer Tax Rex over QuickBooks Sync?
A business that sells online in multiple US states, collecting sales tax in each, might prefer Tax Rex. The automated sales tax reporting and filing features will save significant time and effort compared to manually managing those tasks. This is particularly beneficial if the business doesn't otherwise need the full accounting synchronization offered by QuickBooks Sync.
