France CTC (FNFE) · validation rule

France CTC (FNFE)Warning

BT-23 carries the French billing frame — B1/S1/M1 for a straightforward invoice, B2/S2/M2 for one already paid, B4/S4/M4 for a final invoice after a deposit, and so on for goods (B), services (S) or mixed (M). It tells the platform which use case the document belongs to, so it is mandatory and cannot be an arbitrary string.

Who has to fix it: The sender

This is a property of the file you received, so it cannot be corrected on your side without changing the document — ask the supplier to reissue it.

Check your own invoice

Drop the file that failed. We parse it, run the official rule sets against it and list every finding with a fix — 20 invoices per day, no key, nothing stored.
