Which rules does the validator check?

The document goes through the same check the Peppol network performs on delivery: the European standard EN 16931 (invoice semantics) and the Peppol BIS Billing 3.0 Schematron (business rules BR-… and PEPPOL-…). We use the same validation engine as our certified access point.

What does a code such as BR-CO-15 mean?

BR-… codes are business rules of the EN 16931 standard (e.g. BR-CO-15 = the document totals must add up), PEPPOL-… codes are the additional rules of the Peppol network. For every error we also show the text of the rule; the most common cases are explained in the guide.

Do you store uploaded invoices?

No. The document is used solely for a one-off validation and is not stored anywhere.

The invoice is valid. Does that mean I can deliver it?

Validity is the first condition. The second is that the customer is registered in the Peppol network; you can check that with our Peppol company lookup. If both conditions are met, you can deliver the invoice, for example through our portal.
