Enterprise billing is already used when a customer has decided on a subscription. A modern enterprise billing system can use the details of the contract to plan when the first invoice must be issued and what the amount will be. Corresponding gateways are used for this purpose.

Enterprise billing software simplifies the process considerably. For example, the payment intervals and the selected payment method are stored accordingly. Recurring billing can be automated. Sales are realized and all data can be evaluated in the accounting system.
