Espatial, maptive and efficient logistics

I use TCF but want to optimize my route more.
Here’s what I’m thinking:
I have my area (Las Vegas) divided into 6 zones.
When a client schedules for a given date, the goal is for my scheduler to fill the day from that zone if at all possible. The problem is that we may drive 15-30 minutes within the zone for other appointments.

I reviewed this year and we wasted a great deal of time driving back and forth. What I am looking for is software that I can insert my client’s addresses and then call the closest neighbor to a scheduled appointment and so on, optimizing the logistics. I’ve found espatial, mapline and maptive and want to know if any of you have used them or have another software that may sync with @TheCustomerFactor.
Thank you all.
