dealing with post dated cheques

dealing with post dated cheques

Hi, can you help me please the best way to deal with this

We sell an item of three months duration that is paid for with post dated cheques in monthly stages

example - item is sold £3000

Cheque 1 is for £1000 due at time of sale (say Sept)
cheque 2 is dated 25th of next month (Oct)
cheque 3 is dated 25th of next month +1 (Nov)

Now, with invoice number one it's simple - i send a standard invoice as usual

But with the other two here's what i want zoho to do

next month i want it to send an invoice on the 25th as paid
the month after i want to send an invoice on the 25th as paid

Thing is, if i create an invoice dated 25th Oct and one for Nov 25th and then apply payments to those invoices also dated 25th oct and nov it classes the invoices as closed.

Im guessing it won't send a closed invoice automatically and we would have to go in and manually send it

can anyone suggest the best and most efficient way of dealing with this as an automatic proceedure from the day the order is placed, so all we have to do is bank the cheques?

Thanks in advance
