Configure Carrier Rules to Select the Cheapest or Fastest Service

You can now include multiple shipping services in a carrier rule and configure Hopstack to automatically select the Cheapest or Fastest option. Services can belong to the same carrier, different carriers, or multiple carrier accounts.

For example, add USPS Ground Advantage and UPS Ground to a rule and select Cheapest to choose the lower-priced service whenever the rule is applied.


Step 1: Open a Carrier Rule

Go to Setup → Rule Engine → Carrier Rules. Create a new rule or edit an existing one, and configure its name and conditions.

When the rule is applied through Apply Shipping Rule Selection in the shipment plan or from the packing screen, Hopstack compares the available rates for the configured services and selects one based on your preference.

Note: Hopstack compares only the services included in the rule. Rules configured with a single service continue to work as before.
