Cross-Border EU B2B Invoicing on Shopify: Mandatory Reverse Charge Rules
For an EU B2B order, check the invoice as well as the VAT validation. A successful lookup, an eligible exemption and a complete invoice are separate parts of the store’s setup.
This checklist explains where Wezy Tax Exempt fits. For the app’s settings and a complete test journey, use the agency setup guide, also available in French.
Check the invoice requirements for the transaction
The European Commission describes common EU invoice requirements and the role of national rules in its VAT invoicing guidance. Invoice details include the issue date, a sequential number, supplier and customer information, the items supplied and the applicable tax information. The customer’s VAT number is required when the customer is liable for the tax.
The wording depends on the transaction’s treatment. Reverse charge requires the words “reverse charge”; an exempt transaction needs the applicable exemption reference or another indication that it is exempt. Confirm the treatment and wording for the merchant’s actual supply before configuring the template.
Review the Shopify configuration first
Shopify Tax offers VAT validation and reverse-charge exemptions in supported journeys, with VAT invoice settings for the native flow. Check the tax service and invoicing setup already used by the store.
Wezy adds its own validation records and configurable invoice-line setup. It does not generate a complete PDF invoice or guarantee an automatic integration with every invoicing app.
Configure the Wezy invoice line
- In Settings > Seller Information, check the seller’s VAT number, company name, address and country.
- Choose Default language for the app’s reverse-charge text.
- Open Invoice Setup and follow its instructions to copy the line into the relevant order notification or invoice template.
- Place a qualifying test order and inspect the document the customer actually receives.
- Test an ordinary taxed order as well, so the template does not show an inappropriate exemption line.
If the client uses a separate invoicing tool, check its supported fields and template behavior directly. An order notification and a PDF invoice may use different templates.
Keep validation evidence distinct from invoice content
Wezy’s VAT Validations view provides the check result and stored VIES consultation proof. Review the record alongside the customer details and final order totals.
A consultation record supports the validation history. It is not, by itself, a complete invoice or proof that every condition for exemption is satisfied. Set document retention according to the merchant’s applicable rules; there is no universal retention period established by this app guide.
Leave a tested setup with the client
Record which template contains the line, where the validation history can be found, and which test orders demonstrate the expected result. Include the Tax Exempt guide in the client handover.
For a setup question, email the store’s plan, tax service, invoicing tool and test outcome to support@wezy.app.
