I posted this under sales and figured it wouldn't hurt to leave it there even though it belongs here--
When a deposit is applied to an invoice at the time of posting, the invoice prints with a subtotal of line items, then tax and freight, then deposit applied, and a total for the invoice.  My AR person won't use the apply deposit in the post because she wants a grand total for the invoice, including taxes and freight, to show before the deposit is applied.  I would like to see a total field added that would subtotal all charges, and then apply the deposit, followed by an invoice balance.
 I was hoping I could modify my form, but apparently we cannot add total fields to the form.  Is it possible to make that possible?
