Headless Commerce vs. Composable Commerce? Or is it?

  • Posted by: Recode

There has been a tremendous shift from traditional monolithic eCommerce architectures to more flexible ones like headless and composable commerce. Platforms like Elastic Path, Shopify, Kibo, commercetools, etc., are only adding to the movement. Overall, this bodes well for the eCommerce ecosystem that needs to be nimble, agile, and responsive to trends.

In this article, we will look closely at headless commerce and composable commerce and if there are any worthwhile differences that businesses should know before they go for either of them.
What Is Headless Commerce?
It was Dirk Hoerig, the co-founder of commercetools, who first coined the term headless commerce in 2013. Fast forward to today, and headless commerce has been soaring through the ranks. Estimates suggest that the headless CMS software market will reach a value of $1.6 billion by 2027, up from $605 million reported in 2022.

Simply put, headless commerce refers to an architectural approach that separates the front-end (UI layer) from the back-end (logic layer) commerce functionality. This means that businesses can edit all the UI elements, like the homepage, landing page, product pages, etc., without actually interfering with the back-end.

What Are Its Benefits?
Well, it allows businesses to:
Be flexible in leveraging the front-end technology of their choice to create seamless and desired customer experiences.
Stay ahead when it comes to personalizing user experiences. Since front-end and back-end functionalities are decoupled, enterprises can make changes to the customer-facing end of the eCommerce website in support of personalization elements.
Pave the way for content-rich storefronts that are not only intuitive but also engaging. In fact, headless commerce can help improve page load times. This directly translates into better use experiences.

All in all, a headless commerce solution results in a more effective workflow, shorter time to market, and quicker development timelines for new features and updates.

But There Are Drawbacks as Well
Businesses might feel that they have less control over the site’s functionality since they aren’t interacting with the back-end.
Headless commerce implementation can be technically complex as well as time-consuming if not done right.
The usability of the site depends on speed and performance, and while you can have a high-performing headless site, it’s not a guarantee.
What Is Composable Commerce? ‘
Composable commerce can be thought of as a more advanced version of headless commerce. While headless commerce decouples the front-end and back-end, composable commerce does the same and, on top of that, introduces modularity to the system. It makes the website components independent from each other, meaning that enterprises have even more flexibility in creating the desired experiences by using the desired technologies and solutions.

Modularity, flexibility, and configurability are the three core principles of a composable commerce approach. It makes use of microservices, API, headless, JavaScript, etc., to help businesses customize their commerce experiences to the desired level.

What Are Its Benefits?
Businesses can choose the best components for each part of their eCommerce solution thanks to composable commerce. Their particular needs can be better served this way.
Depending on how crucial it is, each element of the eCommerce system may have a different internal policy regarding deployment and security. As a result, processes for non-critical components can be made lighter.
Enterprises can facilitate omnichannel customer experiences by customizing and personalizing interactions across various channels and devices.
Much like headless commerce, composable commerce also lends itself well to better and faster web experiences.

But There Are Drawbacks as Well
The complexity of composable commerce is related to the existence of multiple integrations and parallel processing. It might be more difficult to efficiently manage and coordinate microservices when more of them are introduced to the architecture.
At times, businesses might find themselves struggling with functionality overkill, since they might be equipped with resources and functionality that doesn’t add much value.
Multiple vendors in the process can mean multiple dependencies and an increased cognitive load for managing relationships.

While there are many advantages to composable commerce, firms must carefully assess their unique requirements and objectives before starting a composable commerce program.
Headless vs. Composable Commerce: How Are They Different?
Although the notions of composable and headless commerce are related, they are not the same. Yes, both guarantee the separation of the front-end and back-end. The fundamental distinction between both techniques is that headless commerce does not necessarily imply a modular approach to architecture.

Flexibility and Customization
A headless design allows for the autonomous development and deployment of each requisite component by separating the front-end display layer from the back-end. Because developers can pick the best technology for each layer, the user experience can be more specifically designed, allowing for greater personalization.

Composable architecture places a focus on the integration of pre-made, modular components into a seamless solution. By allowing quick creation through the use of pre-existing components and avoiding the need to reinvent the wheel, this strategy enables flexibility. Customization is accomplished by choosing and integrating particular modules that adhere to the project’s specifications.

Integration and Agility
Composable architecture places a strong emphasis on modularization, disassembling complex systems into simpler, reusable parts or services. This improves agility by letting teams easily put together and alter apps using pre-built components. As components are created to function harmoniously with one another, this strategy enhances integration and fosters a more consistent user experience.

The same cannot be said for a headless architecture. While there’s a lot of flexibility on the presentation layer front, a headless solution doesn’t offer the level of independence that a composable solution does. Plus, the customizability comes out to be relatively feeble.

Because modifications to one layer don’t always affect the other, headless architecture can simplify maintenance. However, managing different codebases and ensuring seamless front-to-back connectivity might present difficulties and potentially increase maintenance workloads.

The focus of composable architecture is on creating applications from reusable, modular components or services. This can reduce duplication and encourage code reuse, which helps speed up maintenance. The danger of unwanted side effects can be reduced by isolating and testing updates or changes to a particular component.
Headless Commerce vs. Composable Commerce: Are There Any Similarities?
Besides decoupling that we have already talked about, it’s clear that both headless and composable commerce offer utter flexibility, especially when keeping them relative to traditional eCommerce architectures that entailed back-end provisioning.

Another similarity is that businesses can pursue best-of-breed solutions to facilitate top-notch and personalized eCommerce experiences. They can choose the front-end technology based on their needs.

Finally, both headless and composable commerce offer scalability in supporting the fluctuating demands and user traffic.

At the end of the day, choosing headless and composable commerce implementations should rest on factors such as technical complexity, scalability needed, integration effort, customizations required, etc. Interested in learning more? Get in touch today!
