I have a customer with a simple one entrance door counter, that sends the data to a wireless reciever which is connected to the server in the store. They use "Edge" as there POS software. I'm looking for a way to take the number of sales, and amount of sales from edge, and compare it to the number of people that came through the door, and come up with a closing ratio for there sales reps. Edge will export data, and the door counter exports the count data. Now I need something to make the calculations and report it. The door counter manufacturer recommends crystal reports. I'm open to any comments or suggestions. The key thing here is automation, the customer wants to do as little as possible to come up with the closing ratio.
