Our Verdict
For Shopify merchants primarily focused on selling to other businesses (B2B) within the EU, OO ‑ EU Tax exemption offers a direct and valuable solution by automating the VAT validation and exemption process. Its seamless integration into the checkout is a significant advantage for improving customer experience and compliance. However, for Shopify merchants needing robust accounting integrations, especially those already using QuickBooks Desktop, QuickBooks Desktop by Parex is the clear choice. It provides a straightforward way to synchronize sales data, making reconciliation easier and providing a clearer picture of financial performance within QuickBooks.
Therefore, if a merchant is primarily selling B2B in the EU, the OO app wins. If a merchant's main problem is integrating with QuickBooks Desktop, the Parex app is the winner. They both solve drastically different problems.
