Deliverables with fixed price

These deliverables have a fixed price for the customer, which is shown top left on the deliverable.

The fixed price can be invoiced in stages by adding billing periods in an invoicing schedule. Add an invoicing schedule under the options of the deliverable.

Calculations of time and material can be added to deliverables with a fixed price. These calculations will not be billed to the customer, but are for internal administration.
