Composable Commerce architecture
AI Commerce is an e-commerce platform based on Composable Commerce architecture, which offers companies complete freedom to choose the best technologies in the market and seamlessly integrate them into their business needs. This modular architecture allows online stores to be assembled from exactly those components that support your company's current and future goals – without compromising on usability or performance.

What is Composable Commerce?
Composable Commerce architecture means that the digital whole is assembled from individual and independently functioning components (microservices) instead of using a single monolithic system. Each component has a clear task: for example, product management, customer management, orders, search functions, payment solutions, or payment traffic.
Analogy to "building a dream home"
Instead of a ready-made house package, you can design your dream home exactly the way you want. Composable Commerce provides the same freedom for building online stores: you assemble only those "pieces" that are truly beneficial and support your business goals.

Why choose Composable Commerce?
The market is changing rapidly, and customer expectations in e-commerce are constantly increasing. Traditional, large, and difficult-to-update e-commerce software does not always keep up. The Composable Commerce model offers:
Flexibility: New features can be created or old ones updated without needing to overhaul the entire system.
Rapid innovation: Partners and developers can bring new extensions as independent microservices and release them to users agilely.
Ease of maintenance: Each component is a clear whole. When solving issues, it is known where to look for faults.
Competitiveness: You can leverage new technologies more agilely – for example, search engines, payment solutions, or analytics services.

Key components of Composable Commerce architecture
One of the main advantages of Composable Commerce thinking is that a business can choose the technologies that best serve its operations. Examples of the “pieces” are:
PIM (Product Information Management): Product data management and enrichment.
ERP (Enterprise Resource Planning): Inventory management, pricing, and order processing.
Headless frontend: Separating the user interface from the backend system, which improves performance and flexibility.
CMS (Content Management System): Management of the site and content.
Checkout and payment systems: Smooth payment and customer experience.
Analytics and reporting tools: Measuring and improving business performance through data.
Marketing automation: Managing customer journeys and executing targeted marketing.

Traditional Monolith vs. Composable Commerce
Monolithic e-commerce is one large “system package”, where all functionalities – inventory management, customer management, product data, payment solutions, analytics, marketing – are intertwined. This may initially seem easy (a bit like a “ready-made house package”), but:
Updates and modifications can be expensive and slow.
Changing a small piece can break the whole.
Implementing extensive integrations is laborious.
Composable Commerce divides the whole into microservices that communicate with each other through API interfaces. Each service is developed and maintained independently, which means:
You can choose the services that best fit from the market.
It is significantly easier to update and expand the system.
Different teams or partners can develop their own blocks in parallel, without coordinating a “massive” release rhythm.

Composable Commerce vs. Headless Commerce
Although the terms are often mentioned together, headless commerce essentially means that the frontend or user interface of the online store is separated from the backend. The backend system handles the logic and data storage, while the user interface (e.g., React, Vue, or Svelte application) fetches the necessary data through APIs.
Composable commerce, on the other hand, takes the headless model even further:
Each component (such as product management, search functionality, marketing features) can be selected or swapped separately.
Updating or replacing a single component does not take down the entire online store.
Headless is therefore a kind of “first step” towards a complete Composable Commerce architecture.

Benefits for business
1. Modularity: Each component functions as an independent service, allowing for quick adoption of new features and replacement of old ones.
2. Flexibility: If requirements change, the overall system scales and adapts – components can be added or removed as needed.
3. Open standards: Composable commerce is based on API interfaces and microservices, making integrations with third-party systems easy.
4. Business-driven approach: The solution is tailored entirely to the company's strategic goals, not the other way around.
5. Fast time to market: According to Gartner, users of the Composable Commerce model can achieve up to 80% faster feature adoption than competitors using traditional models.
Vendor independence: The company is not tied to a single technology vendor, but can choose and switch to the most suitable solutions without the risk of vendor lock-in.
