What is SE-R-013?

SE-R-013 is a fatal validation rule defined in the Peppol BIS 3.0 specification. It validates the CompanyID element under Party > PartyLegalEntity in the UBL invoice XML.

When this rule fires, the invoice is non-compliant and will be rejected by Peppol access points and national validation services. The sending system receives a rejection response and the invoice does not reach the buyer.

Why This Error Matters

Invoice will be rejected by Swedish validation. Organization number must pass Luhn checksum.

SE-R-013 is a hard failure. Invoices that trigger this rule are rejected at the access point and never reach the recipient. In Peppol networks, this means your sending system receives an MLR (Message Level Response) with a rejection status. The invoice must be corrected and re-sent, adding delay to your payment cycle.

Invoice Navigator can automatically correct this error in your pipeline. The fix is applied with full audit evidence, so your compliance trail remains intact.

How to Fix It

Check your registration certificate

Find your company's registreringsbevis from Bolagsverket. The org number is printed as XXXXXX-XXXX (6 digits, hyphen, 4 digits).

Verify the number

Remove the hyphen. You should have exactly 10 digits. The last digit is the check digit.

Update your invoicing software

Correct the organisation number in your ERP or invoicing software settings. A single wrong digit will cause this error on every invoice you send.
