Use this screen to calculate retroactive billings.

You can generate bills using revised billing rates that are applied to direct cost amounts or labor hours for invoices previously submitted to your customers. Before running this screen, load labor rates for all of the subperiods that the billing rate has modified. There are several scenarios for which retroactive bills may be required. The first occurs when provisional indirect rates are modified on a project and the new rates must be applied to the direct amounts for previous invoices. This modification in rates may be the result of new negotiated billing rates that were in effect for prior invoices. Another case for which retroactive bills are required occurs when the loaded labor rates are modified on a project, and the new rates are applied to prior periods. These new, loaded labor rates are multiplied by the hours for invoices previously submitted to your customers. Retroactive billings are not required on projects that incur rate modifications on a prospective basis.

The retroactive process is used only for standard bills that were originally generated through the Calculate Standard Bills screen. It produces invoices that you can view and edit like regular bills on the Manage Standard Bills screen. To assist in the review of the retroactive bills, print a worksheet on the Print Retroactive Billing Worksheets screen. The printing and posting of retroactive bills are completed in the same way as regular bills on the Print Standard Bills and Post Standard Bills screens, respectively. For more information, see the "Retroactive Billings" topic.

Execute this process after you have entered your new provisional indirect rates or your new loaded labor rates. If you are using Loaded Labor Rates billing formulas, you must also run the Load Labor Rates screen before calculating retroactive bills. You must run this process for each subperiod for which the new labor rates apply.
