I've been using AWIZ Paysite Manager for many years and can recommend it. I'm setting up more paysites and have purchased more copies of AWIZ. I've looked at other software and AWIZ does most things other programs can do for a lot less money.
Most importantly (for me anyway) it's a one off payment. There is no monthly payment as other programs cost $200+ a month which adds up over the years.
Support is extremely fast and competent and the latest version 6 manual was written by native English speakers and is very easy to understand.
I hope that helps
