Creating A Flat Rate Carrier


This article will walk you through creating a flat rate carrier to give a flat defined rate as an option for customers to select on the front end. You would use this carrier in a scenario where you only want one flat rate to show no matter how heavy an item is or how many of this item you have in the cart.


  1. In ShipperHQ under the Carriers tab, Click “Add New” to create a carrier.
  2. Validate that Carrier Type is set to “Custom Carrier”
  3. For the “Carrier” dropdown, select “Flat”
  4. Name your carrier to any desired name which you can change as needed at any time.
  5. Once you are on the Carrier Overview page, make sure you have selected an “Attached Origin” and given an appropriate Carrier Title that will be displayed on the front end.
  6. In the Shipping Rates tab is where you will set your Flat Rate Shipping amount like $5.95 for example.
    *Note: you can set this to apply per order, item or package.


If you are looking for other options like setting up a Shipping option where you can modify a flat rate based off of weight, price, or quantity then you will need to use the Custom Defined Carrier article and create a Custom Carrier to do this. If you are trying to get live rates with a specific carrier like FedEx or UPS or USPS then you can follow the documentation there to set up live rate carriers.
