When you create an account for Mollie, you have to create a website profile where the website's web address must be entered. If you use an invoicing system and the payments do not go through your website, then still enter your own website and provide a clear description of the products and/or services that you are offering. If you do not have your own website, then please enter the website of the invoicing system that you use with a description of how this system works. We can then check your profile faster. In the comments you can indicate you want to use Mollie for the payments of invoices.
