Estimates and Advance Invoices
You issue advance invoices for estimates that you have made. Preview your specified estimate and then click Create Advance Invoice in the top of the document.
You will be given three options:
% of the full amount
Gross amount
Issue Manually
When returned to the estimate you are permitted to close the transaction through issuing a final invoice. The final invoice will be totalled to be the sum less any advance invoice amounts.
