When you're creating your Delivery Service from your Inventory, you can add Flat Rates based on City, State, or Zip.
Watch the magic happen!
As a note, delivery rates based on location will override your default delivery rates.
Let's take a look at a particular use case. Say you want to charge a delivery fee that applies after a specific mileage (e.g. a $375.00 flat fee plus $2.00 per mile after 20 miles).
You can do this by setting a specific rate for any county/zip code within 20 miles of your warehouse or home base. All other locations, without a specific rate, will default to the $375+$2/mile!
For example, if my warehouse is located in Carmel, CA, then I would add in a flat rate of $375.00 for cities within a 20-mile radius. This ensures that $375.00 is added as the delivery fee when any of these locations are added to a project. If I add a location outside of the 20-mile radius, my delivery fee will default to $375+$2/mile.
