As far as I have seen, ClassiPress bills each posting of an ad. That means, if a customer posts 50 ads, it ends in 50 bills.
Unfortunately this is uncomfortable for the customer but also for me. So is there a possibility to bill once for a several ads? Or is there a possibility to set up sellable couchers payable in advance, so that a customer can consume the value of the voucher?
Example: voucher at a value of EUR 100,- can be consumed by placing ads, each for EUR 2,-. So in this example the customer could place 50 ads with only one payment. This would be also interesting having an eye on costs for finance transactions.
