expenses and timesheet script

[Homer]

I need to include a script on my company web-site that will allow employees to submit expenses and timesheets on-line, each employee will have access to their details via a user name and password.

I do not have a budget for this as my boss is a scrooge so preferably the scripts I am looking for will have to be free, or nearly free. My site is hosted on a Unix server with Perl scripts and MySQL.

Any ideas or if you can direct me to any scripts of this type and I will be very grateful.

Regards

Homer
