PEPPOL-EN16931-R010: Your customer's electronic address is missing. How to fix it

What the rule checks

The rule checks that the invoice contains an electronic address for the buyer, the field "Buyer electronic address" (BT-49). This is an identifier at which your customer receives electronic invoices, such as an email address or a Leitweg-ID, together with a scheme that says what kind of identifier it is. The rule comes from the Peppol rule set; XRechnung validation runs it as well. It checks only that the address is present.

Why files fail it

• An email address is held for the customer, but your software writes it only into the contact details. The electronic address is a separate field with its own scheme; adding another email address to the contact block does not change that.
• The customer record has a field for the electronic address, but it was never filled because no invoice needed it until now.
• For an authority, the Leitweg-ID was entered only as the buyer reference (BT-10), on the assumption that it covered the electronic address too. They are two separate fields.

How to fix it

1. 1Enter your customer's electronic address. The field is "Buyer electronic address" (BT-49) in the standard, and it has two parts: the address itself and the scheme.
2. 2For an email address the scheme is EM; for a Leitweg-ID it is 0204. Only your customer can tell you which address they expect; do not invent one.
3. 3Address and scheme belong together. If the address is in the file without a scheme, the validator reports BR-63.
4. 4In our form the "Email" field under "Customer details" is mandatory. We write that address into the file as your customer's electronic address with the scheme EM, so this message cannot arise on an invoice made here.
