I want to set up a voucher system that customers can pre-pay for services at a discount or something like buy 5 and get one free (used on different days). Everytime the customer use the voucher to pay for services, we will deduct the purchased amount from the voucher balance.
Please show how it can be done.

Might not be the exact sample but may give an idea about the possibilities. I'll continue preparing documents about different uses in few days.
