Sage 100 Contractor Tip : Using 3-2 Menu Option for Percent Billing
If progress billing isn't required, you can still invoice by percentage by using the 3-2 Receivable Invoice menu. On the 3-2 window, before you enter in the information on the grid, select "Options" at the top of the window and select "Contract Summary".
From there, you can enter the percent and select "Calculate Amount to Bill from Percent Complete". Then select "Calculate" and if it looks good, select "Update Invoice". The grid will then be filled in.
