If you've never created an invoice through Pennylane before, or if you're using a new sandbox environment or a new account, chances are your account needs to be set-up. To do so, you need to use the invoice parameter page in our Pennylane app:

- Set up your address, contact information, bank account and logo and don't forget to validate
- Set up the numbering of your invoices. You are required by law to have a sequential numbering of invoices, we will therefore automatically generate the next invoice numbers !
You can also find a step-by-step guide (in French) in our Helpcenter.
