Sales: Show a deposit amount on the invoice

[MiMPhotography]

I do not sell items as a photographer I sell a service. I need to be able to create an invoice that shows the full amount invoiced but not the full amount due. I need it to show the deposit only as being due now or in 48 hours or 1 week. Thereafter the outstanding amount is to show as due and the normal process of adding payments applies. The reason for this is that most of the time photograohers are booked 1 to 2 years in advance.

This program is not really geared for photographers
