DOUBLON: Duplicate invoice
What it means
French e-invoicing reason DOUBLON means the invoice is a duplicate, already issued or received: same number, same seller and same year of invoice date.
The usual cause
The same invoice was sent twice, or two invoices share a number.
How to fix it
Check whether the first invoice is being processed. If this one is different, give it a new number.
