Hi. We have some costumers who do prepayments from a sale order, but who do not want invoice. They expect a final invoice with the total amount of the project as base, plus taxes, minus the prepayments.

   I have tried to create a payment, associate it with the analytical account, etc. but i does not work when the final invoice is created considering paydowns.

   Anyone has a similar problem with any solution?

   Thanks in advance
