At first glance, it may seem like a complex matter, which is why we have created the  Corner Model for you. This is the simplest way to explain the flow of a billing process through a service provider. 

From your perspective, you understand what happens and how to send your invoices to us. We provide security, legal compliance and personalization according to your needs. We also archive and identify them. Then you can see how we can send them directly to your customer or to your or their service provider, all with a track-and-trace feature so you are always aware of the status of your invoice.
