Invoicing a business client in France
I have registered a business under the auto-entrepreneur in France and have not had too many problems with the paperwork so far. I have to raise an invoice soon for work to be done for a business client and I am a bit concerned about the extra information that has to be shown on such an invoice. The specimen facture for client professionnel in the auto-entrepreneur guide shows what information is required (such as, penalty and rate for late-payment, discount conditions, etc.). Googling has taken me to many different sites, but each one seems to have a different answer.
It seems that there are legal obligations for things like the interest to be charged for late payment (for example). How should I go about making sure that I comply with the requirements, please?
