In accounting it is essential to establish an invoice number for each transaction carried out. A business subject to billing must follow a series of rules to comply with the law. These rules are established by both the General Tax Code and the Commercial Code. In the event of a tax audit, failure to comply with these rules can be very costly. In addition, a well-managed accounting requires an invoice numbering system, simply to be oriented.

What are the obligations related to invoice numbers?

When it comes to billing, there are two essential rules. Each invoice must have a unique number and must be issued in a continuous chronological sequence.

As all the invoices are centralized in the same software, you are guaranteed not to make any mistakes in the numbering of the invoices.

Regarding numbering, there are three mandatory data that you must respect to comply with tax regulations:

The invoice number must be mentioned on all issued invoices.

Invoice numbers must be given continuously and without interruption.

The invoices are numbered one after the other according to their date of issue.

Billing: mistakes not to make

To avoid creating problems in your accounting, here is a list of mistakes that you absolutely must avoid:

Delete an invoice and reuse the number for a new invoice;

Use the same invoice number twice for two separate invoices;

Back up an invoice;

Leave spaces between invoice numbers or use the same invoice number twice.

How to correctly number an invoice?

To correctly number your invoices, you can adopt several strategies.

Among the frequent invoice numbering methods, you can opt in particular for:

A simple series of numbers (invoice number 001, 002, 003, etc.).

A continuous chronological sequence followed by a sequence of numbers. For example, invoice numbered 202109-001 which would correspond to the time prefix of the month of September (09) of 2021, invoice number 1.

A sequence of numbers and letters that makes sense for your business. For example, use a prefix like PAR01, PAR02, or MAR01, MAR02 if you have two billing sites, one in Paris and one in Marseille.

You can take many methods, for example based on customer categories or billing sites. One constant must be adhered to: your invoices must be established in a logical sequence. Both for you and for an accountant or the French tax authorities.

The same logic applies to other types of invoices, for example in the case of a deposit invoice.

Tips to correctly number your invoices: use an invoice numbering software

To avoid potentially costly tax audits, you can use auto-dial billing software. It can be very useful, especially if you have to process a large volume of invoices.

Finally, using billing software is the easiest way to reconcile payments. Bank reconciliation is an often daunting task that can quickly turn into a headache if your accounting is not well managed.
