Headless Commerce
Medusa.js development services.
Commerce, without the constraints. We build custom Medusa.js commerce platforms — storefront, commerce logic, integrations, and infrastructure — for businesses whose pricing, checkout, or fulfillment rules have outgrown a hosted platform.
Why headless commerce
The platform stops
being the ceiling
Traditional platforms tie your storefront to their backend. That is fine until you need a checkout step, a pricing rule, or an integration the platform does not support — and you start working around the tool instead of with it.
Own the storefront
The frontend is your codebase, not a theme. Change the buying experience without fighting a template system.
A backend you can call
Commerce logic sits behind an API, so the same catalogue and orders can serve web, mobile, POS, and internal tools.
Integrate without workarounds
Connect an ERP, a warehouse system, or a bespoke pricing engine directly instead of gluing apps together.
Scale what needs scaling
Storefront, server, and background workers run separately, so traffic spikes do not slow down operations.
Why Medusa
A commerce framework, not a platform you rent
Open source, self-hostable
No per-transaction platform fee and no vendor holding your catalogue. Run it on infrastructure you control, or on managed hosting you choose.
Modular by design
Cart, pricing, inventory, fulfillment, and payments are separate modules you can extend or replace individually.
TypeScript end to end
The same language and types across storefront, server, and custom modules, which keeps a small team fast.
Workflows, not patches
Custom logic lives in your own modules and workflows — retryable steps with defined rollback — rather than edits to core, so upgrades stay possible.
A real admin included
A working dashboard from day one, extensible with your own pages for the parts of the business it does not know about.
Standard Node tooling
Node.js, PostgreSQL, and Redis — infrastructure most teams already know how to run and hire for.
Honest fit
Medusa is not
always the answer
Medusa is our main commerce specialization, which is exactly why it is worth saying when it is the wrong tool. Complexity, budget, integrations, in-house engineering, and how much control you actually need all point somewhere — and sometimes that is Shopify or WooCommerce. We will say so before you commit a budget.
Medusa makes sense when
- Your checkout, pricing, or fulfillment rules do not fit a standard platform
- You sell across regions or channels with genuinely different logic
- You need deep integration with an ERP, POS, or internal system
- You want to own your data, your hosting, and your roadmap
- You are already on Medusa and need a team to take it further
- You have engineering capacity, or you are hiring a partner who does
Shopify or WooCommerce may be better when
- You need a standard catalogue and checkout live in a few weeks
- Your team is non-technical and needs to change everything self-serve
- You depend on a specific app ecosystem that only Shopify has
- Nobody will own the platform operationally after launch
- Budget is better spent on marketing than on engineering right now
- You do not expect to need custom commerce logic at all
Architecture
What a Medusa
build looks like
Medusa is a composable commerce framework rather than a hosted store, so a build is assembled rather than configured. This is the shape most of ours take — the modules and integrations change per project, the separation between storefront, commerce server, and data does not.
Medusa in production
One we built
end to end
Kyla & Co sells to Sri Lanka and the rest of the world from one codebase, with currency, payment methods and shipping all driven by region — a Next.js storefront on a self-hosted Medusa backend.

Hire Medusa.js
developers
We take this work as an implementation partner rather than a pool of contractors — a small team that owns the Medusa backend and the storefront as one system, from scoping through to whatever needs building after launch.
A new Medusa build
Discovery, architecture, storefront, and the commerce logic underneath it. You end up owning the code, the data, and the infrastructure it runs on.
An existing Medusa project
Take over, extend, or unblock a codebase someone else started — custom modules, workflows, admin extensions, and the upgrade path back to a supported version.
A migration onto Medusa
From Shopify, WooCommerce, or a bespoke platform. The data moves; the harder half is reproducing the rules, integrations, and edge cases your current store has accumulated.
Ongoing engineering
A development team after launch: new features, integrations that break when a third party changes an API, monitoring, upgrades, and performance work.
Process
How a Medusa
project runs
Five stages, adapted to commerce. The unglamorous parts — catalogue shape, tax, fulfillment rules — get decided early, because they are what a build actually gets stuck on.
Discovery
Catalogue, checkout, regions, tax, fulfillment, and the systems that have to stay in sync. This is also where we establish whether Medusa is the right answer at all.
Architecture
What belongs in Medusa, what belongs in a custom module, what stays in the storefront, and which integrations are load-bearing. Infrastructure is decided here, not at launch.
Build
Storefront, commerce workflows, custom modules, admin extensions, and integrations — sequenced so a working buying flow exists early rather than at the end.
Launch
Payments, inventory, shipping, tax, and every integration tested against real cases. Migrated data and redirects verified before DNS moves.
Ongoing
Monitoring, Medusa upgrades, integration changes, performance, and the next round of development.
FAQ
Questions
we get asked
What is Medusa.js development?
Building an ecommerce system on Medusa, which is an open-source commerce framework rather than a hosted store. Catalogue, cart, pricing, and order logic run on your own Node.js server, and the storefront is a separate application — usually Next.js — that talks to it over the Store API. Most of the work is the commerce logic and the integrations, not the theme.
Why use Medusa.js instead of a hosted platform?
Control, mostly. You can change how pricing, checkout, and fulfillment behave instead of working around someone else's data model, you keep the data and the hosting, and there is no per-transaction platform fee. The trade-off is that it expects an engineering team behind it — ours or yours.
Why hire a Medusa.js development company rather than a general web agency?
Because the hard part is not the storefront. Knowing how modules, workflows, and the pricing and inventory models actually behave is what stops a project from re-implementing half of Medusa badly. It is our main commerce specialization, and we would rather not learn it on your budget.
Can you build a custom Medusa storefront?
Yes, and that is the usual arrangement. A Next.js storefront against the Store API, with the product, cart, and checkout experience built around your catalogue rather than adapted from a theme. We build the storefront and the backend as one system, which is where most of the awkward edge cases get resolved.
Can you migrate from Shopify or WooCommerce to Medusa?
Yes. Products, variants, customers, historical orders, pricing, and inventory all move. What takes the time is not the data — it is reproducing the rules, integrations, and edge cases your current store has accumulated: checkout behaviour, shipping logic, promotions, regional rules, and whatever an app was quietly doing in the background. Redirects matter too, since a migration that loses your URLs loses your rankings with them.
Can you integrate Medusa with an ERP or POS?
Yes, and it is one of the better reasons to be on Medusa at all. Integrations are written as modules and workflows against your actual system — ERP, POS, warehouse, shipping, or a bespoke pricing engine — instead of assembled from whatever an app store happens to offer. Sync direction, conflict handling, and what happens when the other system is down get decided deliberately.
Can you build B2B or wholesale commerce on Medusa?
Yes. Customer groups, account-specific price lists, quantity breaks, purchase orders, and approval steps are things you model rather than buy. That is more work up front than installing a B2B app on a hosted platform, and it is the reason genuinely complex B2B often ends up here.
Can you take over an existing Medusa project?
Yes. We start by reading the codebase and telling you honestly what state it is in, including how far it has drifted from a supported version and what the upgrade path costs. Then we work on it.
Do we have to self-host Medusa?
No, but something has to run it. Medusa can go on managed hosting, on Medusa's own cloud, or on infrastructure you control — we usually deploy with Docker to a provider you own. We can hand the infrastructure over entirely or keep running it for you.
Is Medusa.js production-ready?
It runs real stores today, including ones we have built. It is a framework rather than a hosted product, so it expects engineering behind it — which is the trade-off you are accepting in exchange for control.
How long does a Medusa project take?
It depends on catalogue complexity, how many systems have to talk to each other, and how much of your commerce logic is genuinely custom. We scope this properly before quoting rather than giving a number up front.
What happens after launch?
Someone has to own upgrades, monitoring, and the integrations that break when a third party changes an API. We offer that as an ongoing arrangement, or we document and hand over to your team.
