Set up per-case invoicing

To invoice a customer recurrently and on a per-case basis for time and overtime, perform the following steps:

1. By using the Non-stock items (IN202000) window, create a non-stock item of the Labour type to represent hours.
   For details, see: About non-stock item support.
2. In the Contract items (CT201000) window, create a contract item.
   In the Recurring item window, specify the non-stock item created in Step 1 as the one provisioned recurrently.
   Also, specify the recurring and extra usage prices of this item.
   Fill in other required parameters (and any optional ones) at your discretion. For details, see Configure a contract item.
3. By using the Contract templates (CT202000) window, create an active contract template with scheduled invoicing.
   Add the contract item created in Step 3 to the contract template.
   For more information, see Configure a contract item.
4. Initiate the contract in the way that suits your needs; now you can proceed with the contract fulfillment.
   See: About contract setup and activation for details.
5. Invoice the contract according to its schedule, as described in: About contract invoicing.
