This FAQ answers the most common questions about the EU Tax Exemption App, based on real support requests.

If something doesn’t work as expected, it is almost always related to Shopify tax settings, market configuration, or pricing logic — not the VAT validation itself.

VAT validation & general behavior

Draft Order Logic vs Standard Checkout Logic

Shopify plans & checkout limitations

Markets, pricing & taxes

Cart & theme issues

Customers, emails & data

Translations & text

Compatibility & limitations

Still stuck?

If something still doesn’t work:

Double-check Markets and tax display settings
Verify pricing logic (inclusive vs exclusive)
Test with a real EU VAT number
Contact support with collaborator access

Final note

Most issues are configuration-related, not bugs.
Once set up correctly, the app runs reliably with no daily maintenance.
