What is the best way to charge customers for their services


I want them to fill out a form of where they live, name, phone number, email, the plan they want, stuff like that...

I want to have a record of every customer that fills out a form. Then, I want them to go to a new forum that lets them choose method of payment, i.e. credit card, paypal, online check.... I also want a record (that attaches to the other record) of whether or not they paid.. and if they did, how much, and how long (1 month or 1year)

I want all these records just for bookkeeping purposes and stuff...

What is the best/most effecient way to go about this?

Hey,

We use mySQL database for storing our clients info and HostCharge for CC payments. There is lots of software packages that offer that sort of service.
like:
- www.phpmanager.com
- www.modernbill.com
- etc.
