Im looking for advice on a very simple web interface (SIMPLE!) CRM solution for a Linux based web server, using PHP and MYSQL. Im a web developer with reasonable experience in PHP/MYSQL and dont have the time to develop this app myself. The client wants to track basic customer information (email, name, address, phone number) contact occurrences. Additionally, they have some product literature on the website (PDFs) that they want to protect to the extent of requiring a person to register before they have access.
They have no other needs presently like e-commerce.
So, were looking for a front end registration system for free stuff with a backend administration page for the office staff to gather sales leads. Free would be nice, too!
All of what Im looking at on Sourceforge is in alpha or beta, or is overkill for this simplistic need.
