Medusa.js ecommerce
development services.

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.

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.

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.

Yes — most of this work is remote by nature, and the brands it suits are usually the ones selling across borders. A Medusa build for a US or EU merchant tends to turn on the same set of things: pricing and tax per region, the payment methods buyers in that market expect, and fulfillment that behaves differently depending on where the order came from. We are registered in Sri Lanka and deliver remotely, which is worth knowing up front rather than after you ask where our office is.

Yes, and this is a reasonable reason to be on Medusa rather than a hosted platform. Regions, tax rates, and tax-inclusive or tax-exclusive pricing are part of the data model, and tax calculation is a provider you can swap — so a store can charge EU VAT under OSS thresholds, apply UK VAT separately post-Brexit, and defer US sales tax to a service like Avalara or TaxJar for nexus and rates. We build and test the integration; we are engineers rather than tax advisors, so the rates and thresholds themselves should come from your accountant.

Yes, though not as individual contractors you manage. We take Medusa work as a small team that owns the backend and the storefront as one system — which is usually what a company means when it goes looking for Medusa developers, because the awkward problems live between the two. If you have an in-house team and want a Medusa specialist alongside them, say so when you get in touch and we will tell you honestly whether that shape works.

That is the usual arrangement. An implementation partner owns the architecture decisions, the build, and the handover — including the ones that are inconvenient to raise, like whether the catalogue shape you have described will survive contact with your ERP. We would rather have that argument in discovery than in month four.

Yes. Some engagements are an architecture review, a second opinion on whether Medusa is the right platform, or a read of an existing codebase before you commit a budget to extending it. We would rather be paid for a week of that and tell you not to build than be paid for six months of the wrong build.

Yes, if you already have a Medusa backend you are happy with. A Next.js storefront against the Store API — product, cart, and checkout built around your catalogue rather than adapted from a theme. We will read the backend first, because a storefront can only be as good as the commerce logic it is calling, and it is better to know that before we start.

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.

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.

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.

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.

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.

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.

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.

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.

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.
