This is one idea for zoning but open to suggestions. Zoning Zip Codes by Color Groups. If these five zip codes = Blue Work Orders on the Schedule board your call taker would be able to quickly see where to put call to minimize drive time on your tech. If you could fit one or two more calls in a day because you were able to minimize drive time, save on gas, and put that much more money in the bank; worth every penny. Zoning is needed so badly in Total Office Manager for call takers to easily see where to place callers. One way is to assign zip codes a color so when they show up on the schedule board, blue, yellow, red, etc. You know where to quickly find a spot that is near the customer you are on the phone with.
