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 rejected by Peppol access points and never reaches 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 — the invoice must be corrected and re-sent before it can reach the recipient.
Invoices with an incorrect Swedish organisation number will be rejected. Swedish tax authorities and Peppol Access Points validate this number. If the check digit is wrong, the receiver cannot verify your company identity.
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.
