Progress Invoicing

Is it possible to perform “Progress Invoicing” on an invoice? I am currently creating additional invoices for partial billing throughout the life cycle of an accepted quote that has been invoiced. It would be beneficial to partially bill an existing invoice.

Invoice 100
Progress invoice 1 - invoice 100-1
Progress invoice 2 - invoice 100-2
Final invoice - invoice 100-3


You could set the partial/deposit field 3 times to accept 4 payments on one invoice.

I have clients that require a unique invoice number for each payment

In that case maybe you can use a recurring invoice?

The recuring would not remove the amount paid from the initial invoice

Rather than create 4 invoices you could create one recurring invoice which sends 4 invoices.
