Invoicing a fixed-price project involves a payment plan and the actual invoicing procedure.
Payment plan
You can invoice fixed-price projects on the basis of a payment plan. The payment plan is set up on the project in the form.
The payment plan can be set up with an optional number of milestone payments. Each milestone payment must be entered as one entry in the form.
Example
The payment plan could be set up as follows:
-
20% on signature of project contract.
-
30% on first delivery.
-
15% on second delivery.
-
35% on final delivery
Invoicing procedure
When the milestone payments are ready to be invoiced, you apply the procedure for invoicing on-account amounts.
