Calculating Invoice Amounts for Milestones or Progress

When you complete a milestone for a contract, you must enter the date in the Actual Complete Date field for the billing event. At this time, the system updates the Complete Yes field to Y. You can then invoice for the milestone at the percentage that you have specified.

When you generate invoices, the system compares the cutoff date for the invoice generation with the actual completion date. If the generation date is the same or later, the system processes the billing event for the milestone billing line. At this point in the billing process, you cannot change the billing amount.

After the system invoices for an event, it updates the Billed Yes field to Y. At this point, the billing event is protected and you can no longer change the information for the event.
