Overview

Why stores use it

Business buyers across Europe now expect a structured e-invoice, not just a PDF. Germany requires every business to receive them since 2025 and to send them from 2027, Belgium switched to Peppol in 2026, and more countries follow. This plugin makes a valid XML e-invoice for every business order, on its own.

Add your seller details once. From then on, when a business order reaches Completed (or Processing, your choice), the plugin builds the e-invoice, checks it against the EN 16931 rules, gives it the next invoice number and attaches it to the order email. Refunds get a matching credit note.

Without the pluginRejected

  • A PDF no longer counts as the invoice
  • Buyers reject XML that fails the rules
  • Fixing invoices by hand burns numbers

With Peppol and XRechnung E-InvoicesCheck passed

  • Peppol and XRechnung for every business order
  • Checked before any number is used
  • Credit notes from refunds on their own

E-invoices are becoming the law across Europe. Get them right from the first order.

Latest release

Version 1.0.0Latest

  • NewFirst release.

Full changelog →Compatible with WC 8.0+

Does it send invoices over the Peppol network?

No. It creates the e-invoice file and emails it to the buyer. Sending through a Peppol access point needs an account with an access point provider.

Is the output valid?

The XML follows the official Peppol BIS 3.0 and XRechnung 3.0 UBL specifications and is checked against the main business rules before it is saved. Test invoices and credit notes made by the plugin pass the official Peppol BIS 3.0 and EN 16931 rule sets and the KoSIT XRechnung validator. Ask your tax adviser how the rules apply to your business.

Can I fix an invoice after it was created?

Fix the order, then press Recreate in the E-invoice box. The file is built again with the same number and date. For a change in amounts, make a refund so a credit note is issued, as invoice law expects.

What happens when the check fails?

The order gets a Check failed status, the problems are listed in plain words on the order screen and the store gets an email. No invoice number is used until the check passes.

Does it work with PDF invoice plugins?

Yes. It runs next to them. Turn on Use the PDF invoice number so both documents share the same number.

Does it work with the Checkout block?

Yes. The buyer fields are registered with the Checkout block and the classic checkout.

Are VAT numbers checked online?

No. Only the format and check digit are checked, on your own server.
