Read our Free Composable Commerce Guide and see what the top considerations are for evaluating & composing your unique eCommerce solution with Elastic Path


What is Composable Commerce?


Composable commerce is the modern approach by which eCommerce teams are empowered to select and assemble various “best of breed” commerce solutions and compose them to satisfy their exact business requirements.

Instead of trying to force-fit standard “out-of-the-box” eCommerce functionality to fit your needs, composable commerce leverages modern technologies and approaches like MACH (microservices, APIs, Cloud, and Headless) and JAMstack (JavaScript, APIs, & Markup) architectures to adapt to the rapidly changing market dynamics now and in the future.

Traditional platforms: Why are we shifting away from them?


A traditional commerce platform comes equipped with a set of pre-existing functionality, bundled together as an “all-in-one” solution, from a single vendor. The platform approach has been largely positive, as businesses ventured down the path of doing business online for the first time and consumer expectations, at the time, drove the requirement for mostly simple, standardized commerce experiences.

Virtual Shopping

1) Consumer expectations for modern, engaging experiences have skyrocketed over the past several years, mostly as a result of the leading internet giants raising the bar in terms of what consumers expect. We are more hyper-connected than ever before, and customers expect to be able to buy goods and services whenever and wherever they are. This has forced commerce businesses to rethink the tech stack used to power their online businesses so they can keep pace, let alone innovate and differentiate, in a saturated B2C market.


2) Gone are the days when customers only expected eCommerce experiences from B2C companies. B2B focused companies are trying to embrace this new era but are coming upon roadblocks to deliver experiences as seamlessly as B2C companies have done in the past. Most B2B instances are more complex by nature and are therefore struggling to launch profitable eCommerce initiatives with traditional commerce platforms, because they just can’t support their complex business requirements.

No “One Vendor” can provide the best functionality for all applications you need for running your eCommerce experience. So, by going with this option you stand the risk of having basic capabilities of your complete tech stack; losing the ability to control and customize the functionality of your eCommerce Platform; and trying to fit your business requirements to their architecture.



Composable Commerce: How is it changing eCommerce experiences?


The Composable Commerce design principle leverages "best-in-class" commerce services, to deliver all the functionality you would have previously gotten exclusively from one eCommerce platform. This new approach utilizes the various vendors that provide much more robust functionality for the one thing they do, rather than relying on one vendor to produce standard functionality fit for everyone. Gartner also explains of how Composable Commerce is for the future.

Composable Commerce embraces uniqueness, differentiation and understands that “functionality fit for everyone” will not be enough. The composability technique empowers you to literally select and assemble functionality for your specific business requirements. Let this not be confused with being left alone on an empty canvas with just a bunch of vendors. This new approach is designed to be a web of vendor-supported technologies that emphasizes round the clock and assured support, reliability and security from a vendor like Elastic Path.

An example of a typical composable commerce stack would include best-in-class services covering all the capabilities commonly included in a traditional eCommerce Platform, such as order management, inventory, Salsify product information management (PIM), TaxJar for tax, shipping, fulfillment, Contentful for the content management system (CMS), and Stripe for the payment gateway, just to name a few. There is a healthy balance of functionality from your supported vendor and external expert commerce services within the stack, which eliminates the possibility of compromising for certain functionality for your commerce experience. This architecture caters to both your business and technical needs.

Composable Commerce FAQs


MACH Architecture



A dynamic arrangement of loosely coupled units that each draw from their own data and capable of functioning individually, as well as coherently with each other. The decoupled nature increases speed and productivity, while its flexibility in program languages usage, increases scalability and autonomy across cross-functional teams.

API- First

The customizable API-First approach is responsible for composing multiple services into a commerce stack that allows you to choose what’s needed for your precise business requirements; be it technology stack, integrations, or feature requirements. This eliminates the bloat of the platform and unnecessary complexity and rigidity that comes with standardized plugins, without compromising on the design or consumer experience.


The cloud native architecture provides insurmountable scalability to launch fast and reliable experiences to a large consumer base. There's no need to miss a beat during peak traffic instances due to seasonal business, as the platform will automatically scale for your needs. Launch across all channels of your choice with assured speed, performance monitoring and data security. 


The headless approach fosters infinite flexibility to design, iterate and launch differentiating experiences on the front-end, independently at your own pace without risk of tampering with old experiences. This level of flexibility enables you to support any and all touch points to ensure a seamless experience for consumers to finish their purchase on any device at their convenience.
