The Ecommerce market is gigantic and it is growing at exponential levels worldwide. As the number of online merchants grows, customers will have multiple options for purchasing products. Thus, they look for better options and experiences. With the ever-changing consumer behavior and demands, commerce merchants must go omnichannel to satisfy customers across various channels. The introduction of headless architecture took the Ecommerce market by storm. It completely revolutionized the Ecommerce industry and the ease with which websites are built. One step ahead, composable commerce is making its way to help Ecommerce businesses serve customers in the most unthinkable ways. This new approach will alter how commerce systems are created and emerge as the future of Ecommerce. Let’s learn more about composable commerce architecture:

What is Composable Commerce?

Composable commerce is selecting the best-of-breed Ecommerce components and combining them into a custom application for specific business needs. All this is made possible through Packaged Business Capabilities (PBC). Furthermore, composable exchange uses modern technologies like MACH and Comstock (JavaScript, APIs, and Markup) to adapt to the ever-changing market dynamics.

What are Packaged Business Capabilities (PBC)?

PBCs are the building blocks of composable Ecommerce. They offer simplified and agile solutions to business problems on demand. They help you quickly integrate new capabilities, maintain holistic analytics, and increase cross-functional collaboration. Here are some of the benefits of PBCs for large businesses:

  1. With PBCs, even complex systems are simplified. Each system here is self-contained, portable, and easily integrated with other systems.
  2. The increased agility provided by PBC architecture facilitates improved team collaboration. When there are new ideas, they can be quickly evaluated and deployed without affecting the existing systems.
  3. To get a competitive edge, you may design solution-oriented technologies and layer features on top of them. By controlling your back end autonomously, you may scale your business at any moment and increase stability.

The Significant Evolution of Ecommerce

1. Monolithic Ecommerce

The traditional and monolithic systems tie front-end and back-end infrastructure together. One wrong move can disrupt the whole system. The real challenge appears as the business grows. Web traffic increases and customizations get complex; agility is minimized and the business risks failing.

2. Headless Commerce

Headless Commerce developed a flexible system with independently working front-end and back-end systems to resolve the issues faced by an all-in-one platform and tightly coupled infrastructure. The decoupled systems enabled high customization, flexibility, portable back-end data, and improvised data structure. It helped developers to modify website content without disturbing the complex backend systems.


While headless commerce includes decoupled front-end and back-end systems, microservices architecture provides a completely decoupled platform from service-oriented design, allowing companies to combine the finest individual features for their enterprises.

M: Microservices

The microservices architecture allows software systems to be constructed by linking together multiple single apps. Each program is executed and scaled individually without affecting the others. The architecture offers a decentralized and independent approach to qualify specific business requirements.

A: API-first

API refers to an Application Programming Interface, which accommodates multiple software applications to communicate with one another seamlessly. API-first means you create software to solve a specific problem and then connect it to make it compatible with other services.

C: Cloud-Native

Cloud-Native computing takes advantage of SaaS technologies to let developers build, deploy and maintain modern software applications on cloud infrastructure.

H: Headless

Headless enables several customer touchpoints and ensures a seamless cross-channel customer experience through headless architecture.

The decoupled units within the MACH architecture encompass more than just the back-end and front-end systems. They refer to independent functional units or microservices that communicate with each other through APIs. In this approach, each component is separate, allowing you to select the most suitable solutions based on your client’s requirements.

4. Composable Commerce

Composable commerce is a new layer combining headless, Jamstack, and MACH features to develop future-proof Ecommerce systems. To summarize, it is a business-centric strategy that prioritizes business cases first, unlike other models that prioritize developer experiences.

Fundamental Principles of Composable Commerce


Composable Ecommerce has a modular structure–any component can be pluggable, scalable, and replaceable anytime. That means you can add, delete or modify each element without affecting the application’s other parts. If you want to change your website content or build an Ecommerce store, composable commerce makes it possible through interconnected components instead of a pre-packaged system.

Open System

An open ecosystem allows you to create best-of-breed solutions using several third-party applications and other best practices.


With Composable Commerce, you can create highly personalized solutions tailored to your clients. You can scale your application up or down and quickly adapt to changes in your environment.


Composable commerce solutions comprise all the necessary tools and capabilities for consumers and development teams offering complete control over the business process at a lower cost and risk.

Composable Commerce vs Headless

While both composable and headless commerce may seem similar, the key difference lies in their approach. Headless commerce is all about decoupled front-end and back-ends, whereas composable ecommerce is a collection of best-of-breed solutions operating independently.

How Composable Commerce Benefits Your Business

Composable Ecommerce provides cutting-edge benefits that aren’t available in the traditional model. Some of the benefits are:

1. Development-Friendly

Developers may use composable commerce to change functionality without impacting the entire system. Programs may run significantly quicker and be modified without the fear of the whole program failing.

2. Simplify Customer Journeys

The integrated APIs of composable commerce let you craft seamless customer journeys with multiple integrated on-platform touchpoints, including chatbots, reporting dashboards, self-service tools, etc.

3. Better Agility

“Agility” refers to a business’s ability to react to emerging challenges and market opportunities rapidly. Composable offers a flexible environment that allows businesses to deliver unique customer experiences without depending too much on technology.

4. Future-Proof Approach

The modular commerce solution is built to adapt to changing customer demands and expectations. You don’t have to wait for your platform’s “latest release” and updates; your business progresses on autopilot mode.

5. Faster Time To Market

Simple integrations allow your business to update its features whenever required, thus synchronizing with the market trends and consumer demands.

6. Lower TCO (Total Cost of Ownership)

With a monolithic structure, you will be subjected to a contract for a fixed amount of time. Breaching the contract or switching vendors is a costly and complicated affair. Due to the reduced cost of modular building, composable commerce has a lower total cost of ownership.


How do I get started with composable commerce? You might already be using this without knowing. If you follow the JamStack approach for web development and also use headless solutions, you are already using the composable commerce architecture. The move from monolithic to headless architecture has revolutionized web development. Learning how this composable commerce can take ecommerce to the next level will be interesting.
