Online payment

You can also pay by bank transfer. The IBAN can be found at the bottom of your invoice. 

Errors may appear when you attempt a payment, generally in the following cases

• There is an error on one or more digits, CCV or expiration date
• The CB does not have sufficient funds or the bank does not authorize the payment
• The email entered is invalid
• The amount is invalid (to insert an amount with decimal, use the period and not the comma)
• Unauthorized characters were used in the fields (example: &$€*£/?, etc.)
• Too long a delay occurred between page loading and payment

If the problem persists after checking all these points, open this page in a new browser (eg: Firefox if you were using Safari or Chrome, and vice versa) and try the payment again. If the problem persists, contact
