I was just wondering if I made a system that you could sign up for and you could redirect customers with a link or I could build it into your site layout that your that your customers could login to would u sign up for it for a tiny fee. In this system your customers could see payments they owe, payed invoices, dates that services were on, next service date, they could pay on paypal or they can print up an invoice and send a check to your mailing address. This system them would have an admin system where the owners of these companies coudl input all this data. Thsi would all be done in php. Please write any feedback.
