We are thinking of invoicing our customers at the beginning of the year for the total amount due, but our customers pay on a monthly payment plan. Is there anyway to invoice, so that the invoice shows each month, but not due until that month. eg. The total amount is $3000 but they pay over 10 months ie $300 per month is owing.

I assume you could enter each invoice item and then change the description and the date, but that would take forever. Is there another way? We do not have the inventory or order entry module as this is a service that we are offering.
Thanks
