Multiple Delivery Calculations – Sitecore Commerce

While working with one of the clients recently, we had to implement a product-specific delivery calculation. Certain products sold online, are delivered by the company itself and they have fix delivery charges for each region. While certain products(depending on the size/nature) are delivered through other courier services. Since the delivery charges can differ depending on the courier service, we have to calculate/fetch delivery charges for particular products.

Let’s say a customer adds two products to the cart

  1. Bluetooth Speaker
  2. Baby Cart

Since speakers are delivered by the company itself, we use the internal delivery fee using a delivery fee book. For baby-cart, we integrate to the external courier delivery fee service. For the sake of this article, I am calling Speaker as Internal product while baby-cart as external product.


In commerce engine solution we have a feature called fulfilment, this feature has CalculateCartDeliveryBlock which calculates the delivery fee for internal products. This block is configured inside ICalculateCartPipeline of Sitecore. ConfigureSitecore.cs below


We also extended this CalculateCartDeliveryBlock in a way that it calls either internal calculation for a product or calls the external API to get the delivery fee depending on the nature of the product.

This is how the block code looks like. The actual code is little different, I made it simpler to demonstrate how we can achieve this.

Few facts about the code which are not obvious here

  1. We add up all the delivery fee for all the products and show it to the customer
  2. GetExternalDeliveryFeeCommand calls the external API to get the delivery fee


Putting together all the pieces
