The invoice is a document that details the services or goods sold and precisely identifies the beneficiary.
To generate an invoice, your sale must necessarily be linked to a customer AND an invoice address.
The invoice can be printed in the 'Payment' section of the sale by clicking on the 'PDF A4' button.
The invoice can also be sent via email or retrieved using a QR code.

If the sale is not assigned to any customer or is linked to a customer without an invoice address, the generated document will be a RECEIPT.
If the sale has not yet been closed, the document will include the mention 'PROFORMA', indicating that it is a draft document.

Once the sale is closed, it is no longer possible to modify the invoice address.
In case of an omission or error, the sale must be canceled and re-entered.

In 'Settings/Users/Access Management', you can enable the right: 'Pre-select automatically the customer invoice address'.
This allows the sale to be automatically linked to the customer's default address when the customer is added to the sale.

To configure your invoices, go to 'Settings/Printing/PDF A4 Invoice'. More information.
The invoice must comply with specific formal requirements including mandatory mentions, which can be found on your tax administration's website.
You must ensure that these mentions are present on the documents you issue.
