Composable commerce is all the rage nowadays, and it’s not just a passing trend. This innovative approach is poised to redefine how we do e-commerce, possibly for good. 

 In the ever-changing digital commerce landscape, buzzwords come and go. But composable commerce isn’t just another fleeting fad. The service-oriented approach isn’t new but reaches new heights when paired with MACH architecture’s core principles.

What is Composable Commerce? 

Composable commerce is a modern approach to e-commerce architecture that emphasises flexibility, agility, and modularity. Unlike traditional monolithic systems & breaks down functionality into smaller, independent components.

“Composable building blocks,” can be easily assembled and orchestrated to create tailored commerce experiences that meet specific business needs.

Real Life Example

For instance, a well-known UK-based business that has adopted composable commerce principles is ASOS, an online fashion and beauty retailer. In addition to product management, inventory tracking, and payment processing, ASOS has a highly modular architecture utilizing microservices. By embracing composable commerce, ASOS can swiftly adapt to changing fashion trends. Furthermore, it offers personalised shopping experiences and efficiently scales its platform to meet growing demand. 

UK-based businesses like and use composable commerce strategies to improve their e-commerce capabilities.

Composable commerce principles help businesses stay competitive in the digital marketplace.

The Evolution of Composable Commerce  

Think of composable commerce as the evolution of how we build software systems. It’s like moving from constructing a single, massive building to assembling a collection of modular, interchangeable components. 

Consider a traditional software application as a monolithic structure – all the code tightly bundled together, making it difficult to modify or scale. Imagine breaking down this monolith into smaller, independent services, each responsible for a specific function. These services, known as microservices, act like individual building blocks that can be assembled and rearranged to create custom solutions tailored to specific business needs. 

This approach draws heavily from the success of microservices architecture, which has revolutionised software development by enabling greater scalability, resilience, and innovation. Microservices allow developers to focus on building smaller, more manageable units of code, which can then be easily combined to create complex systems. 

Composable commerce

Instead of just breaking down the backend infrastructure into microservices, it extends modularity to every aspect of the e-commerce ecosystem – from frontend interfaces to third-party integrations

For instance, imagine an online retailer that wants to add a new payment gateway to its checkout process. With a composable commerce approach, the retailer can simply plug in a pre-built payment microservice, rather than having to rewrite the entire checkout system. This modularity not only streamlines development but also enhances agility, allowing businesses to adapt quickly to changing market conditions and customer demands. 

In summary, E- commerce builds upon the principles of modularisation and decoupling within software development, leveraging microservices architecture to create flexible, adaptable e-commerce solutions. By breaking down complex systems into smaller, interchangeable components, businesses can achieve greater scalability, resilience, and innovation in the ever-evolving digital landscape.

What are the benefits of composable commerce? 

  • Flexibility: Composable architecture enables businesses to swiftly adapt to changing market conditions and customer preferences.
  • Scalability: Breaking down monolithic systems into smaller, reusable components allows for seamless scalability without compromising performance. Example: A retail website experiences a surge in traffic during a holiday sale.
  • Innovation: Composable architecture fosters innovation by empowering developers to experiment, iterate, and deploy new features independently. Example: A software company utilising commerce continuously releases new features and updates to its e-commerce platform, such as AI-driven product recommendations or chatbot customer support, enhancing the overall customer experience. 
  • Personalisation: Businesses can create highly personalised customer experiences by assembling tailored solutions from a variety of best-of-breed components.  
  • Cost Efficiency: Leveraging modular components and cloud-based services, commerce helps reduce development costs and time-to-market. Example: A startup launching an e-commerce platform utilises composable commerce to access pre-built microservices for essential functionalities like user authentication, payment processing, and inventory management, reducing development time and infrastructure costs.

In summary, composable commerce offers businesses in the UK the flexibility to adapt, scale, innovate, personalise, and operate cost-effectively in the dynamic digital marketplace, ultimately driving growth and customer satisfaction.  

 Challenges of composable commerce

1. Integration Complexity: 

  • E-commerce involves integrating various independent components, which can lead to complexity in managing these integrations effectively. 
  • Imagine composable commerce as building a puzzle with pieces from different sets. Ensuring that each piece fits seamlessly together requires careful coordination and planning. 
  • To overcome integration complexity, businesses need robust API management and integration tools. These tools help streamline communication between different components and ensure smooth interoperability. 

2. Governance and Control: 

  • Think of E-commerce as a bustling marketplace with vendors offering various products. Managing this marketplace requires effective governance mechanisms to maintain order and reliability. 
  • For instance, an e-commerce platform may implement strict access controls, encryption protocols, and auditing mechanisms to safeguard customer data and ensure compliance with regulations like GDPR (General Data Protection Regulation).

3. Talent and Skills:

  • Adopting composable commerce may require businesses to upskill their existing teams or hire new talent with expertise in microservices architecture and cloud-native technologies. 
  • Consider E-commerce as embarking on a journey to explore new territories. To navigate these uncharted waters, businesses need skilled guides who understand the terrain. 
  • Upskilling existing teams involves providing training and resources to familiarise them with microservices architecture, containerisation, orchestration platforms, and cloud-native technologies. 
  • For example, an e-commerce company may invest in training programmes, certifications, and workshops to empower its development teams with the necessary skills and knowledge to succeed in the composable commerce landscape.
