I've been using www.landscapebilling.com
for years, and at first I thought maybe you were doing something similiar to what they have. But from looking at your site, you dont provide any customer account management abilities? So if Suzy Q. is my customer, will she have an account that I set up using your program, that I can create invoices to, and track her account balances? Or are you simply a "paypal" type program, just being a middle man for money, with no customer account management abilities?
