Create a full Payroll report that includes:

Commission and tips (like current commission summary)
Total hours from time clock report
Bonus points for:
Method of tracking days off in the report (official days off, not just "days not scheduled")
area to add adjustments to pay before downloading the report. (for training, paying for discounted services, etc...)

This one report would be almost everything needed to enter into any payroll system with some basic formatting.
