The short answer
BR-61 fails when a cac:PaymentMeans has code 30 (credit transfer) or 58 (SEPA credit transfer) and no cac:PayeeFinancialAccount/cbc:ID inside it. Add a cac:PayeeFinancialAccount to that payment means with the seller's account number, such as an IBAN, in cbc:ID.
If the account element is already there and only its cbc:ID is missing, BR-50 is reported as well. If the code itself is wrong and the buyer will not pay by transfer, change the code instead of adding an account.
What the rule checks
The rule runs on every cac:PaymentMeans. Once spaces around cbc:PaymentMeansCode are trimmed, a code of 30 or 58 requires the path cac:PayeeFinancialAccount/cbc:ID to exist; every other code passes.
Only existence is tested. An account cbc:ID that is empty or holds only spaces satisfied this rule when tried, and was then reported by BR-50 and PEPPOL-EN16931-R008.
An account number placed anywhere else does not count. With the account removed and an IBAN-shaped value in cbc:PaymentID, the rule still failed when tried.
The codes in scope are exactly 30 and 58. Code 42 (payment to bank account) and code 31 (debit transfer) both passed without any account when tried.
The two rules divide the cases like this: no account element gives BR-61 alone, as in the recorded example; an account element without cbc:ID gives BR-61 and BR-50; an empty cbc:ID gives BR-50 and PEPPOL-EN16931-R008.
| Term | Meaning | UBL element |
|---|---|---|
| BT-81 | Payment means type code | cac:PaymentMeans/cbc:PaymentMeansCode |
| BT-84 | Payment account identifier | cac:PaymentMeans/cac:PayeeFinancialAccount/cbc:ID |
How an integration ends up here
Possible causes, from the shape of the rule rather than from measured usage:
- Credit transfer is set as the payment means for every invoice, but bank details are only written when a setting is switched on for the seller entity.
- The seller holds accounts per currency and none is configured for the invoice currency, so the account block is left out.
- The account number is written only into the payment reference
cbc:PaymentIDor a free-text note. - The invoice will be paid by card or direct debit, but the payment means code is hard-coded to
30.
How to fix it
- Decide how the buyer will pay. For a transfer into the seller's account keep
30, or58for a SEPA transfer; for any other method use that method's code and stop here. - Take the account number from the seller's bank details for this entity and currency, never from the buyer's data.
- Add
cac:PayeeFinancialAccountinside thecac:PaymentMeans, aftercbc:PaymentIDas in the corrected invoice, with the account number as its first childcbc:ID. - Add the account name in
cbc:Nameand the bank identifier, such as a BIC, incac:FinancialInstitutionBranch/cbc:IDif you have them. When tried, an account holding only itscbc:IDpassed every layer.

</cac:PaymentTerms>The failing invoice has a code 30 payment means with a payment reference and nothing else; the corrected one adds the whole cac:PayeeFinancialAccount with identifier, name and branch. The failing document reports only BR-61. BR-50 stays silent because there is no account element for it to inspect.
What the validator reported

Where it applies
- Applies to UBL
InvoiceandCreditNotealike; a credit note with code30and no account reported this rule when tried. - This is an EN 16931 rule, and the Peppol layer passes in the recorded example.
- Each payment means is checked separately. A second
cac:PaymentMeanswith code30and no account was reported atcac:PaymentMeans[2]when tried. Had the second one used a different code,UBL-SR-47would also appear, because all payment means codes in a document must be equal. - A payment means code outside the list, such as
BACS, is reported byBR-CL-16and escapes this rule even with no account, so correcting that code to30can reveal this finding.

Scope and source
Written for Peppol BIS Billing 3.0.21 (May 2026), EN 16931 1.3.16, as applied to UBL 2.1 Invoice and CreditNote documents. Other profiles, syntaxes and releases can define this identifier differently. Guidance version 2026-09-24.1: source checked 2026-09-24, explanation last updated 2026-09-24.
The official definition of BR-61 carries the normative wording and test. This page is our explanation of it, not a copy.
Guidance does not change the engine verdict. Fixing this finding does not mean the document passes every layer, and validation does not certify legal or tax compliance or transmit a document over Peppol.
