Is there a way to have a $500 invoice yet only have $250 of it due now and the rest due later? I have a client that is an artist and only wants half due upfront to reserve the spot in his queue and the rest due after the first sketch. If this is possible, that would allow me to switch away from InvoiceNinja completely. InvoiceNinja is a bit slow and graphics don’t always load and you can’t customize it that well :< (for the self-hoested)
