Delivery Zones
From FloristWiki
You can mantain your delivery zones within Mercury Delivery. (Those customers who do not use Mercury Delivery can use the Delivery Zone screen in Mercury Administration to maintain your delivery zones. Changes made to zones in the Mercury Delivery application are copied to Delivery Zone option in Mercury Administration, and vice versa.)
IMPORTANT: You cannot delete a delivery zone on non-canceled orders for the current date or future date. Inactive zones are visible in Mercury Delivery, but cannot be used in delivery routes. Inactive zones do not appear in Order Entry or Point of Sale.
There are three ways that you can create delivery zones in the Mercury Delivery application: by map, ZIP/postal code, or address. In each case, a map is displayed on the screen to help you create your delivery zone. Your store address is also pinpointed on the map. You can also remove unused delivery zones.
