I work on a lot of computers and I am looking for a CMS that I can keep track of clients and what computers they have. So the client part needs to be very customizable so that I can put in type of computer, speed, RAM, etc. I then would like to be able to create invoice/quotes under their client file. If the clients could view their invoice and pay online that would be a plus. Any suggesting would be greatly appreciated.
Here's a Free OpenSource custom computer builder script that might help with custom building features & billing at least. I've never tried it, but the reviews are pretty good on it http://sourceforge.net/projects/computerbuilder . Hope it helps, Good luck!
I looked at computer builder and it was pretty good but it did not have anything for keeping track of clients. I think what I am looking for is a web based pos system that runs on unix php and mysql and has a customizable client database.
