The purpose of flat rate shipping is to offer to customers a way of standardizing their shipping costs, controlling for the large variations that can occur due to dimensional weight, shipping distance, and seasonal peaks. This makes flat rate shipping a highly useful shipping method for online sellers who are looking to optimize their shipping strategy. 

This module allows you to restrict it to certain customers’ groups, countries, and website pages (for example, checkout and backend) as well as specify the shipping module names both in the backend and on the front end according to the required language and enable tracking.

It is also possible to:

  • specify the shipping cost for all orders, 
  • use the certain tax class on the shipping cost (for example, EU - 20% or none), 
  • assign this shipping method to the certain shipping zone (for example, All World or EU),
  • set up the preferred delivery date rules,
  • specify the sort order of display. 


This module is used in the backend and on the front end and its settings can be found under Modules and Shipping tabs.

Shipping method widget is added to the checkout page.
