What are some cost effective solutions that can provide secure billing/membership management for a SaaS with varying subscription options ? I am looking for something like aMember, but I think it's quite expensive.
I really would not like to store any type of CC data, and prefer to use the backend system of the payment processor.
In addition, what is your choice for credit card processing ? In the past, Paypal payments were easily reversed due to chargebacks, etc. Should Paypal still be accepted ? Anyone use AlertPay (I heard that they call to verify orders) ?
