Services · MedusaJS development

Commerce
as software you actually own.

  • Open source
  • TypeScript
  • Modular
  • Marketplace / B2B

We design, build, and evolve commerce platforms on MedusaJS for brands and operators that have outgrown SaaS limits. Custom modules, marketplace and B2B architectures, headless storefronts, and deep integrations — all in TypeScript, all owned by you.

What we build

Everything Medusa can do, done properly.

From a first Medusa implementation to a marketplace platform or a large B2B replatforming — we work across modules, admin, and storefront, not just one layer.

01

New implementations

New Medusa platforms built from a clean base. Custom modules, data models, and workflows aligned with your business — without inheriting someone else's shortcuts or SaaS constraints.

02

Replatforming from SaaS

Moves from Shopify, BigCommerce, or Magento to Medusa when the platform starts blocking the business. Data migration, checkout preservation, SEO, and zero-downtime cutovers.

03

Marketplace platforms

Multi-vendor marketplaces built on Medusa's sales channels, stock locations, and custom marketplace modules — vendor onboarding, order splitting, payouts, and commissions.

04

B2B & wholesale

B2B platforms with company accounts, customer-specific catalogs, price lists, quoting, NET terms, and approval chains — wired into your ERP or CRM from day one.

05

Headless storefronts

Storefronts on Next.js, Remix, or custom React frameworks using Medusa's Store API. SSR, ISR, and edge-first delivery where it actually moves the numbers.

06

Custom modules & integrations

Custom Medusa modules for payments, shipping, fulfillment, tax, ERP, PIM, and marketing — plus deep integrations with existing systems, end-to-end TypeScript.

Specialized focus · Marketplace & B2B

Models Medusa was built for.

Medusa's modular architecture makes marketplace and B2B a natural part of the platform rather than workarounds forced into place. Sales channels, stock locations, customer groups, and custom modules give us the building blocks we need to do it properly.

01Marketplace

Multi-vendor, marketplace-native.

Medusa's sales channels, stock locations, and module system let us build true multi-vendor platforms: one storefront, many sellers, split payouts, per-vendor workflows, and a real marketplace admin — without bolt-on apps fighting the platform.

  • Vendor onboarding, KYC, and dedicated admin dashboard
  • Sales-channel-per-vendor or custom marketplace module
  • Order splitting and per-vendor fulfillment workflows
  • Split payouts via Stripe Connect, Adyen, or local processors
  • Commission engine, reporting, and payout statements
  • Moderation, disputes, and review workflows
02B2B

B2B built on primitives, not plug-ins.

B2B on Medusa is a first-class extension of the core: company accounts, customer groups, price lists, tax profiles, quoting, and approval workflows — all TypeScript modules you own, version, and deploy like the rest of your codebase.

  • Company accounts, buyer roles, and permissions
  • Customer-group-based catalogs and price lists
  • Volume, contract, and negotiated pricing
  • Quote-to-order, PO checkout, and draft orders
  • NET terms, credit limits, and approval chains
  • ERP / PIM / EDI integration via custom Medusa modules

How we engage

Three ways to work with us.

01

Greenfield build

From brief to launch.

A complete implementation of a new Medusa commerce platform. We own architecture, module design, admin, storefront, integrations, and go-live. Fixed scope, clear milestones, a platform you can actually grow on.

02

Migration & replatforming

Leave SaaS limits behind.

Moving from a SaaS platform or legacy custom stack to Medusa. We audit the current state, plan the data and SEO migration, ship a modern Medusa build, and keep traffic, rankings, and revenue intact through cutover.

03

Retainer & continuous delivery

Experienced TypeScript team, on demand.

A long-term partnership for teams that treat commerce as a product. Prioritized backlog, regular releases, ongoing performance and CRO work, module maintenance, and integrations — with a predictable monthly capacity.

Process

From diagnosis to long-term growth.

Every engagement follows the same proven framework — adapted to scope and stage, but never cut short just to hit a deadline.

  1. 01

    Diagnosis

    A paid, time-boxed audit of your current stack, data model, integrations, and commercial goals. Output: a concrete plan, a realistic budget, and the risks we see before we start building.

  2. 02

    Architecture

    We define the stack and the data model: which Medusa modules to use as-is, which to extend, and which to replace. Marketplace vs. single-tenant, B2B model, integrations, storefront framework. Every decision is documented and justified.

  3. 03

    Build

    Short iterations, working preview environments from week one, code review on every change, and TypeScript end-to-end. Modules, admin, storefront, and integrations delivered under one engineering standard.

  4. 04

    Launch

    A rehearsed cutover: data migration, 301 map, DNS plan, analytics parity, monitoring, and a hypercare window. Launch day is boring by design.

  5. 05

    Growth

    After launch we stay involved — performance, CRO, new modules, integrations, and the next phase of the roadmap. Commerce is a product, not a project.

Technology
