Custom Shopping Cart Development with a Microservices Approach

Within 17 years in ecommerce development, Smart Softwareprovides consultancy on implementation of custom ecommerce solutions.


A shopping cart (also referred to as an ecommerce website or a webstore) is a web application used for digital commerce. A microservices approach to shopping cart development is applied when one needs flexibility in designing business logic and user experience for their online presence. A custom-built solution with decoupled microservices architecture is easier to evolve in the long run.


At its core, a microservices-based solution is a number of loosely coupled services interacting via a communication protocol and each responsible for a separate function. A custom shopping cart is built by putting each piece of ecommerce functionality into a separate service. These functional blocks connect to customer-facing digital touchpoints via APIs.


You obtain a shopping cart solution attractive for customers and returning the best value for investment when you secure fundamental ecommerce functionality and add advanced capabilities for a competitive edge.
