Composable commerce is an approach to building an eCommerce architecture from modular components (Packaged Business Capabilities, or PBCs) that interact via APIs.

Each component is a separate service (such as search, cart, payments, or analytics) that can be replaced or updated without impacting the entire system. It is a combination of headless commerce, microservices, API-first, and cloud-native approaches that makes digital commerce as adaptable as possible.

The composable commerce development market is growing rapidly: according to Precedence Research, its volume in 2023 exceeded $5.2 billion and is forecast to reach over $31 billion by 2034 with a CAGR of over 17%. 

That is why composable commerce development companies and headless commerce specialists are becoming key drivers of digital transformation, helping brands scale faster by integrating API-first solutions and modular services.

According to the Elastic Path – State of Composable Commerce 2024 report, more than 90% of brands have already adopted at least one component of composable eCommerce architecture, and many report a significant reduction in time-to-market for new products as a result of modular integration and API-first design.

For comparison, Statista records a steady growth of global eCommerce, creating a favorable environment for rapid scaling through composable commerce service providers and the integration of modern eCommerce software development and retail software solutions.

How top partners in composable commerce were chosen: selection criteria and key competencies

To compile the list of top composable commerce agencies, we applied a detailed set of transparent criteria that help businesses choose a reliable partner for complex projects.

First, we evaluated experience in eCommerce and retail, as it’s crucial that a company understands B2C, DTC, and omnichannel specifics and has successfully implemented projects in these sectors.

We also focused on expertise in MACH, API-first, microservices, and headless commerce, not just theoretical knowledge but proven implementations of custom headless and composable solutions.

Another key factor was the portfolio of integrations: leading partners can seamlessly connect PIM, CRM, OMS, analytics, and search tools into a holistic composable architecture. We also considered global presence and the ability to deliver software engineering services internationally, as well as ongoing post-launch development and innovation support.

Finally, transparency of pricing and cooperation models, together with verified reviews, ratings, and industry awards (Clutch, GoodFirms), confirmed each company’s reliability and quality of service.
