DE-R-031

Layer peppol·Checked against Peppol BIS Billing 3.0 2026.5

What does DE-R-031 mean? If both supplier and customer are located in Germany, and if the group "DIRECT DEBIT" (BG-19) is delivered, the element "Debited account identifier" (BT-91) shall be provided.

Why did my invoice fail DE-R-031?

On domestic German invoices, if the DIRECT DEBIT group (BG-19) is provided, it must include the Debited account identifier (BT-91) — the buyer's account from which the payment will be collected. A direct-debit instruction without the debited account is not executable. In UBL BT-91 is cac:PaymentMeans/cac:PaymentMandate/cac:PayerFinancialAccount/cbc:ID.

Official rule text

If both supplier and customer are located in Germany, and if the group "DIRECT DEBIT" (BG-19) is delivered, the element "Debited account identifier" (BT-91) shall be provided.

Common causes

• cac:PaymentMandate present with a mandate ID but no cac:PayerFinancialAccount
• Buyer IBAN not collected when the mandate was set up
• Account identifier placed in the payee account element instead of the payer account
