When I was the Director of Logistics for a very large nursery, we used PC Miler to do routing for us. You simply input all of the stops, and then let the software auto re-route the loop.

I am not sure how much the software costs now, but it was very effective and they updated the maps several times a year. It would also give you total miles, just in case you are paid/charged that way. We would pay the miles based on PC Miler (avoiding small roads, or roads that are truck restricted).
