Set up per-activity invoicing

To invoice a customer recurrently and on a per-activity 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 field, 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; see: Configure a contract template for more information.
4. Initiate the contract in the way that suits your needs; now you can proceed with the contract fulfilment.
   For details, see: About contract setup and activation.
5. Invoice the contract according to its schedule.
