How much does it cost to create a micro-enterprise?

Creating a micro-enterprise is completely free. Registration is done online via the INPI one-stop shop (procedures.inpi.fr). Beware of paid sites that offer to do the process for you.

How long does it take to receive your SIRET?

Generally, you receive your SIRET number between 1 and 3 weeks after registration on the one-stop shop. If your file is incomplete, it may take longer. You can check progress on procedures.inpi.fr.

Can you create a micro-enterprise while being employed?

Yes, combining employment and micro-enterprise is possible provided you respect your non-compete clause and loyalty obligation to your employer. Check your employment contract and collective agreement.
