Mandatory mentions to appear on your invoice
- Identification of the parties
It is crucial to include your contact details as well as those of your client on your invoice. Thus, your first and last name are essential, as they represent the business name of your enterprise as a self-employed entrepreneur. You must also include your postal address and your SIRET number.
Do not forget to include the name, first name, and other contact details of your client.
- The invoice number
Each issued invoice must have a number. The numbers used must follow sequentially while being preceded by the mention “Invoice No.” or “Credit Note No.” in the case of a credit note. It is important to note that chronology is very important to ensure the uniqueness of each invoice number.

- The billing date
The date of issuance of the invoice is also important. It often corresponds to the date of receipt of the product or the date on which the client benefits from your service.
- A table describing your services
Your invoice should include a table that outlines on each of its lines the date of the operation, the description of the product or service, the quantity, the unit price excluding tax, and the total price.
Discounts, rebates, or refunds, and especially the total amount excluding tax billed must appear in the last lines of the table.
- The VAT exemption
As a self-employed entrepreneur, you are required to indicate on your invoices the mention: “VAT not applicable, art. 293 B of the CGI”.
- Late payment penalties, discount conditions, and collection fees
Finally, your invoice must include the rate of penalties that you will apply in case of late payment and especially the collection fees that will automatically apply (€40, which is the amount set by law) as well as the discount rate in the case of early payment.
