E-commerce on headless architecture
An online store on headless architecture: the storefront (frontend) is separated from the commerce engine, while the catalog, cart and checkout work via API. A fast storefront for high traffic and a large catalog — and selling across several channels at once.
E-commerce on headless architecture — overview

Headless e-commerce is an online store where the storefront is separated from the commerce engine. The catalog, cart, checkout and payments live in a headless platform (for example Medusa, Saleor or a headless setup) and work via API, while the buyer sees a separate fast storefront. Roughly, the storefront and the “warehouse with a checkout” work separately, like two buildings with a high-speed link between them: the storefront can be made as fast and unusual as you like without touching the order logic. From one engine you can sell across several channels at once — the site, a mobile app, marketplaces: products and stock are kept in one place. Unlike a regular store on an off-the-shelf platform (see the “Online store from scratch” service), headless pays off when speed with thousands of products, peak loads or selling across several channels matter. For a small store it is overkill. The base price starts from 300,000 ₽; the final cost is usually higher and depends on the catalog size, number of channels and integrations.
Problems we solve
- With thousands of products and during sales spikes, a store on an off-the-shelf platform slows down — buyers abandon the cart.
- You need to sell in several places — the site, an app, marketplaces — but products and stock are kept in different systems.
- A standard storefront template does not allow the UX you need — customization hits the platform’s limits.
- Storefront speed directly affects conversion, and a heavy monolith cannot keep up.

FAQ
When should you choose a headless store over a regular one?
Choose a regular store on an off-the-shelf platform if your catalog is up to a few hundred products, one sales channel and a standard design — it is faster to launch and cheaper. Headless pays off when you have thousands of products, need several channels at once, high load or a non-standard storefront: the frontend is faster, the engine is more flexible, sales are omnichannel.
Can payment, 1C and delivery be connected?
Yes. Headless works via API — we connect payment systems, 1C or a warehouse, delivery services and marketplaces. We estimate complex integrations separately after analysing the task.
How much does it cost and what does the price depend on?
The base price starts from 300,000 ₽, and the final cost is usually higher. It depends on the catalog size, number of channels, set of integrations and storefront complexity — we calculate it after you describe the task.
