Progress billing involves billing your clients even if the time and expense entries are not approved or released for the project. Later you can tie them to the invoice so that the job costing is accurate. You can do that in the following way:
1. In Billing Review, select the project to be billed. You may not have all the time and expenses recorded against it or they may not yet be approved for billing.
2. You can change the Expense amount directly on the grid and generate a write-up/down for the time entries to get the invoice amount correct. Else, simply enter the desired Net Bill amount.

3. Process the billing record and generate the invoice as usual.
4. After all the time/expense entries have been entered and approved, use the Change feature of the respective screens to associate the entries with the existing invoice (generated above).

Note: This option is only available when viewing by Project and NOT Employee in Sheet View/Expense Log.
5. If required, you can recalculate any markups (on expenses) or write-up/down (on time entries) while associating the entries to the previously billed invoice.
