I've metioned in another thread that I am thinking about going into web host reselling. As I work another job, I am trying to automate as much of the process as I can. Does anyone know of any good payment processors that would be able to automatically send some type of response when paid, so that an invoice could be marked paid in a database so that I dont have to check manually? (I'm kind of ignorant of payment processors and how they work.)

How do others process their payments? Also I have heard there are some resellers that will process payment for you as part of their service - anyone know of any company that will do that?

Thanks
