Composable Commerce: How It’s Reshaping Modern Ecommerce

Previously, commerce platforms offered a uniform, blanket solution, ideal for businesses to craft basic online customer journeys. This approach was effective during the dawn of digital commerce, catering to customers’ need for straightforward online shopping experiences.

Yet, merely setting up a store doesn’t cut it anymore — businesses must now differentiate themselves. Legacy structures can’t keep pace with the escalating demand for immersive digital interactions and the prominence of e-commerce as the primary business interface. With the fast-paced evolution of consumer behaviours and an increasingly crowded online business landscape, companies are pressed to innovate their tactics.

That’s where composable commerce steps in — moving away from the standard platforms, it empowers businesses to build distinct commerce experiences by tailoring their technology stack. This adaptation enables them to stay current with e-commerce trends and carve out a unique position in a saturated market.

What is Composable Commerce?

Composable commerce involves selecting top-notch tech from many vendors instead of leaning on one vendor’s standard solution.

For example, a composable stack may include services like TaxJar for tax matters, AfterShip for fulfillment, Bloomreach for customer engagement or product discovery, Shopify for commerce, and Stripe as a payment gateway. Each of these services performs a distinct role in the e-commerce landscape, aiding companies in better catering to their customers’ needs.

Composable commerce isn’t like the old e-commerce models that tie you to a single vendor or a fixed setup. It uses flexible microservices—separate functions you can grow, modify, or change individually. So, businesses can choose and assemble components to craft a system that fits them perfectly. The goal is to enhance customer experiences and rise above the competition.

Benefits of Composable Commerce

  • Flexibility with vendors: Composable commerce means businesses aren’t locked into a single vendor’s solution. They can tweak strategies and explore new business models—IT staff aren’t as tied down.
  • Agile structure: This approach supports quick, efficient delivery. It ensures faster market access and improved customer experiences at every touchpoint.
  • Open environment: An open source platform lets brands build their best solutions. They can use third-party apps, their in-house tools, or bespoke apps to do this.
  • Cost management: Composable commerce helps manage costs effectively. Businesses select only the needed features and vendors, reducing operational expenses.
  • Gaining a competitive edge: Businesses with custom applications will outpace those with off-the-shelf solutions. According to Gartner, by 2023, firms using composable commerce will implement new features 80% quicker than their competitors.

Drawbacks of Composable Commerce

  • Vendor handling: Adding a new microservice means more vendor negotiations, from purchase agreements to terms and conditions. The process also involves integrating it with your existing tech. Remember, every vendor has its own service level agreement, handling challenges like traffic spikes differently.
  • Connecting microservices: It can be a tall order to link microservices from different vendors. Businesses have to develop a user interface to unite these components. Some people have compared it to building with LEGO blocks, but without an instruction manual.
  • Team adaptation: With composable commerce, your e-commerce stack gets more variables. It’s a complex process, and during implementation, teams may struggle to grasp how to use the software or its capabilities.

How Composable Commerce Functions

Composable commerce breaks down a conventional, single-block e-commerce platform into smaller, more manageable pieces. Each piece, or microservice, does a particular job like managing product catalogs, processing payments, or handling shipping details. These microservices talk to each other using APIs, making communication smooth.

The part the customer sees, the front end, is separate from the underlying e-commerce structure, the back end. This separation allows businesses to create custom experiences for their customers across various channels. 

This is the work of headless technology that separates what the customer sees from the commerce platform. The entire composable commerce setup lives in the cloud. This means businesses can easily change the size or scale of the system as they need to.

Imagine an e-commerce business. They are struggling with an old platform. It’s rigid and not meeting customer needs. The platform is also tough to maintain because any changes affect the entire system. They decide to try composable commerce.

Here’s their action plan:

  • Microservices: They start by breaking up their old platform. Each function like product catalog, checkout, and shipping gets its own microservice.
  • Headless technology: Next, they separate the customer-facing side of their platform from the back-end operations. They use headless technology for this.
  • Best-of-breed vendors: They handpick the top software vendors for each microservice. The vendors are connected through APIs. For instance, they might choose a vendor that specializes in fraud prevention for their payment gateway. For shipping, they might choose a vendor with real-time tracking.
  • Cloud-native infrastructure: Finally, the company takes their new system to the cloud. This allows them to scale and adapt as their business needs change.

Composable Commerce vs. Modular Commerce

Composable commerce may sound like a buzzword, but it’s actually a powerful next step from modular commerce. If you’re familiar with modular commerce, you know it’s part of the headless commerce family. In headless commerce, the front-end—the bit your customers see—doesn’t interfere with the back-end—the bit that keeps everything running.

Now, modular commerce took this idea and went a step further. It separated all those backend services like databases and file storage. It meant you could choose and pay for only what you needed, not a prepackaged system. Composable commerce takes that flexibility up another notch. It gives retailers total control, not just of the back-end, but also the front-end. You choose the services you need, when you need them.

If you want an analogy, consider this. If modular commerce is like combining bricks from different LEGO sets, then composable commerce is like combining bricks from any toy brand, in any way you like.

Headless Commerce vs. Composable Commerce

When you hear about composable commerce and headless commerce, you might think they’re the same. They’re not. They’re similar, but they also have key differences.

Headless commerce is an e-commerce solution where the front-end—the part customers see—is separate from the back-end—the part that handles all the work. This approach is common with a content management system. For example, Bloomreach offers Bloomreach Content. It’s a headless CMS that lets companies manage their storefront easily. They can add products to any page through powerful APIs.

Even so, headless commerce and composable commerce aren’t the same. You can’t use the terms interchangeably. Here’s why:

While going headless is many firms’ first foray into composable commerce, more advanced builders like a CMS or personalization provider are required. This helps complete the e-commerce experience to meet customer expectations. Headless commerce and composable commerce do work together. The technologies used need to be headless for composable commerce to work.
