Matching payments to orders: can someone point me in the right direction?

Matching payments to orders: can someone point me in the right direction?

Hi,

I work as a manufacturer's rep in the theatrical lighting industry.  I've successfully set up a Zoho database to handle the "front end" of my business, i.e. the constant stream of purchase orders in my territory (all identified by a unique order #).

Once a month, I get an Excel file of commission payments for that month (which also references the order #)

I'd like to be able to import the monthly report and have it automatically reconcile payments with orders, but I'm really lost as to the first step.  Can someone give me 1/2 a clue, or is this a good place to consider hiring a developer?

Thanks,

Doug
