Hi there, i just expecting a little help from any of you.
i need to find a client management (PHP) software.
i don't know things about that,
i am doing a website about tourism over here, i am gonna put
small guest houses, small hotels, restaurent .etc in our area,
to our website.

*, these are ma requrments..
i need to install or copy some php codes to my server,
those codes must handle a MySQL database or someting like that.
that data base should keep information of my clients, and
remind me or send automated e mails when their AD or web pages
going to expire from my website. and its better if it can also
handle the billing part.

thats the main thing.

and it must be very simple

please let me know if any one know any PHP software for that.

thank you!
