Headless Commerce Development

In short

Headless commerce splits your storefront from your commerce backend so each can change independently. Kryeo builds the storefront in Next.js and the backend on Medusa (or connects to an existing commerce API), then hands over the repositories, database, and hosting in your name.

Headless commerce is a way of building online stores where the storefront and the commerce engine are separate systems that talk over an API. Kryeo builds the storefront as a custom Next.js application and the engine on Medusa, an open-source commerce backend, or connects a new storefront to a commerce API you already run.

What "headless" actually means

In a traditional platform like Shopify or WooCommerce, the storefront theme and the commerce backend ship together. Changing the customer experience means working within the theme system the platform gives you.

Separating the two has three practical effects:

  • The storefront can be rebuilt, redesigned, or re-platformed without migrating product and order data.
  • One backend can serve several front ends (a web store, a mobile app, an in-store kiosk, a marketplace feed) from the same catalogue and inventory.
  • Backend services can be swapped individually. Search, payments, tax, and the CMS are integrations, not parts of a monolith.

When headless commerce is the right call

Headless is not a default upgrade. It is worth the extra build cost when at least one of these is true:

  • You need a storefront experience the platform themes cannot express, such as custom product configurators, content-heavy landing pages, unusual navigation, or a design that has to be exactly right.
  • Your pricing, bundling, or checkout logic does not fit the standard model, such as B2B price lists, quote flows, subscriptions with custom rules, or multi-currency with local logic.
  • You are paying a percentage of revenue to a platform and that number has grown past what self-hosted infrastructure would cost.
  • You want the same product and inventory data behind more than one application.

If a themed store on an established platform is working for you, headless will add cost without a clear return. We will say so.

What Kryeo delivers

A headless commerce engagement produces:

  • A Next.js storefront, server-rendered, fast on mobile, with the product, collection, cart, and checkout flows built to your design.
  • A Medusa backend (or an integration layer against your chosen commerce API) with the data model, pricing rules, and admin extensions your operation needs.
  • Payments, search, and tax wired in: Stripe or your processor, a search provider such as Algolia or Meilisearch, and automated tax where relevant.
  • A content layer so marketing can build pages and edit copy without a developer. Usually Directus; see headless CMS.
  • Staging and production environments, deployment pipelines, and monitoring.
  • A handover: architecture documentation, a walkthrough with your team, and every credential transferred to you.

How we build it

We start with the data model and the API contracts, not the design system. The commerce engine, the pricing rules, and the integration points get written down and agreed before the storefront is built on top of them.

The storefront is a standard Next.js application: the App Router, server components for catalogue pages, and a typed client for the commerce API. There is no bespoke framework to learn. Any Next.js developer can pick it up.

Headless commerce vs a themed platform

 KryeoThemed Shopify / WooCommerce
Storefront flexibilityAny design or interaction, because it is a custom applicationWithin the theme system; deeper changes fight the platform
Time to launchLonger, because the storefront is built, not themedShorter for a standard store
Ongoing platform feesInfrastructure only; no revenue share on the Medusa pathSubscription plus, in some tiers, a percentage of sales
Backend customisationFull, because Medusa is open source and extensibleLimited to apps and platform APIs
MaintenanceYou run the infrastructure, or keep us on to do itPlatform handles hosting and updates
General comparison; the right choice depends on your requirements.

Timeline and cost

A headless storefront on a new Medusa backend is typically a multi-month build. Replatforming an existing catalogue onto a headless storefront is faster because the data and business rules are already defined. Cost is a fixed project fee plus your own infrastructure (hosting, database, and third-party services), which for most stores is a few hundred dollars a month and does not scale with revenue.

FAQ

Headless Commerce Development: common questions

Headless commerce is an architecture where the customer-facing storefront is a separate application from the commerce engine that manages products, carts, and orders. The two communicate over an API. This lets you rebuild or redesign the storefront without touching the backend, and swap backend services without rebuilding the storefront.
