Keeping track of clients/customers?

[KandieMan101]

I run web design/programming business... and I currently keep users in an excel workbook (hehe...). When I started, it was made as a temporary solution, but unfortunately I never got the chance to switch to a "better" system.

My question is, what system do you use to keep track of your customers and everything?

Thanks!

How about something like a MySQL database? :)

Depending on what version of Excel (mabe all of them, but the newest for sure) you can export the workbook as a XML document where you can parse it by PHP or whatever you program in, and enter it into a database for better storing.
