I’m offering a client a 10% discount when buying 10 hours ahead. I was planning to enter this as a prepayment and then raise an invoice (with 10%) discount every time an hour is used.
However, how do I request the prepayment? Do I raise an invoice and then delete it and assign as a prepayment, or do I have to request it outside of QF? Or maybe there is a better way to do this completely?
