Anything that does this?

I need something (preferable something that runs an a LAMP stack) that will keep track and help me with the following:


Accounts/Customers
Quotes/Invoices
Reminder to send recurring invoices
Support requests, specifically how many the customer has used so far (out of 10)

According to my uncle. Excel would do the trick.
