Adjust Billing Details
Adjust the billing details:
- Contract Start: The contract start is relevant for calculating cancellation periods and the earliest possible cancellation dates, in connection with the subscription terms.
- Billing Start: The billing start is the date when the subscription will be billed. By default, this corresponds to the contract start. However, if the subscription is being migrated from a legacy system, for example, this should be set to the date when the subscription should be billed next. The billing interval is determined from this date.
- Contract End: If it is already known at the beginning of the subscription when it should end, the contract end can be specified here. Otherwise, a subscription can be manually cancelled in the future.

Adjust the advanced billing details:
- Order Number / PO Number: Enter the order number or PO number to be assigned to the subscription. The PO number is always displayed on the invoice.

- Subscription Number: By default, the subscription number is automatically generated. However, you can enter a custom subscription number here.
- Custom Name: Enter a custom name for the subscription here. This name is displayed on the invoice and in the subscription overview. By default, the subscription number is used as the name.
