More about PEPPOL-EN16931-R010

XRechnung requires the buyer's electronic address, the address the invoice is delivered to electronically. Like the seller's, it carries a scheme saying what kind of address it is.

For German public bodies this is usually their Leitweg-ID with scheme 0204, the same code as in the buyer reference. For businesses it's typically the email address they gave for invoices (scheme EM), or their Peppol ID if they receive invoices through Peppol. If you're unsure, ask the customer which address they receive e-invoices at.

The fields involved

BT-49 Buyer electronic address: CII ram:BuyerTradeParty/ram:URIUniversalCommunication/ram:URIID; UBL cac:AccountingCustomerParty/cac:Party/cbc:EndpointID

Typical situations

The customer record has an email for correspondence but none marked for invoices.
The Leitweg-ID was entered as buyer reference only, not also as electronic address.

Example

A public buyer's electronic address (CII):

<ram:BuyerTradeParty>
  ...
  <ram:URIUniversalCommunication>
    <ram:URIID schemeID="0204">04011000-12345-03</ram:URIID>
  </ram:URIUniversalCommunication>
</ram:BuyerTradeParty>
