What it means
When an invoice between a Danish seller and a Danish buyer uses payment means code 93 (FIK), the payment reference (BT-83) must be present and start with 71#, 73# or 75#, which is the type code (kortartskode). The account number in the payment details (BT-84), which for FIK is the creditor number, must be exactly 8 characters long.
Why it matters
The type code and the creditor number tell the bank's systems how to process a FIK payment. If either is missing or has the wrong form, the payment cannot be handled correctly, so the invoice is rejected.
How to fix it
In the payment details of your invoicing software, choose FIK (payment means 93). Begin the payment reference with 71#, 73# or 75#, and enter your creditor number as exactly 8 characters. For references starting with 71# or 75#, DK-R-011 also sets the length.
