Go to Clients, then Attendance
Click the "edit"
icon beside an existing delivery route.
Add and remove clients until you have completed your delivery route.
Click on the "Reorder"
Click on the "Optimize with Google"
This will automatically re-sort your list in the order of the best possible route based on the client addresses. Any households that have undisclosed addresses will be at the bottom of the list.
Once the list order has been optimized, click on "Update Route"
to save your changes.
The Google tool can only optimize 25 addresses at a time.
