E-commerce Development
Custom headless commerce built on Medusa.js — own your entire stack, ship a storefront that fits your brand exactly, and scale without per-order license fees.
Get StartedWe build production e-commerce on Medusa.js, the open-source headless commerce platform. Instead of forcing your business into a closed SaaS template, Medusa gives you a modular Node.js commerce engine you fully own — cart, orders, payments, fulfilment, and promotions exposed as clean APIs, with a Next.js storefront we design around your brand. That means no revenue-based fees, no locked-in checkout, and no waiting on a vendor's roadmap to add the feature your business needs. From B2C direct-to-consumer to complex B2B and multi-region catalogues, we architect, build, and support commerce that grows with you.
Key Capabilities
Concrete capabilities we bring to this engagement — not buzzwords.
Headless, API-First Architecture
We decouple your storefront from the commerce backend, so your frontend team ships freely while Medusa handles cart, orders, and payments through clean APIs.
Built on Medusa.js Modules
Medusa's modular engine gives you product, inventory, pricing, promotions, and order management out of the box — extended with custom modules for the logic unique to your business.
Storefront Built for Your Brand
A fast Next.js storefront designed to your brand, not squeezed into a theme — server-rendered, SEO-ready, and tuned for conversion on mobile.
Payments, Fulfilment & Integrations
Stripe and local payment gateways, tax and shipping providers, ERPs and marketplaces — wired into Medusa so orders flow cleanly from checkout to delivery.
Technologies We Use
Proven tools and platforms we apply where they fit — chosen for the problem, not the trend cycle.
Our Approach
A clear path from problem to production — adjusted per service, never one-size-fits-all.
Discovery
We map your catalogue, customer journeys, and the systems commerce has to talk to — payments, fulfilment, ERP, and analytics.
Architecture
We design the Medusa data model and module boundaries, and decide what is off-the-shelf versus a custom module for your business logic.
Development
We build the Medusa backend and the Next.js storefront in parallel, with your brand and conversion baked in from the first sprint.
Integration
We connect payments, tax, shipping, and back-office systems, and migrate existing products, customers, and order history.
Launch
We load-test, harden, and ship to production on infrastructure sized for your traffic, with monitoring and rollback in place.
Support & Growth
Post-launch we iterate on the storefront, add modules as the business grows, and keep the platform current.
Budgets of All Sizes
We work with budgets across the full range. The team adapts scope, size, and engagement model to what you can spend, without lowering the bar on how we build.
Enterprise
Full delivery teams for complex platforms, with the security, compliance, and process rigor large organizations expect.
Growing Teams
Flexible engagements that scale with you. Add capacity when you need it, scale back when you don't, without renegotiating from scratch.
Small Business & Startups
Lean, focused builds that get the essentials right. We help you trim scope, not quality, so a modest budget still ships a solid product.
Why This Matters
Outcomes we aim for — measurable in product quality, speed, and business impact.
You Own the Stack
Open-source Medusa means no revenue-share fees and no vendor lock-in — the code and data are yours.
Build Exactly What You Need
Custom modules and an open API let you model promotions, bundles, and B2B rules that closed platforms cannot express.
Scales With You
A decoupled Node.js backend scales independently of the storefront, from first orders to peak-season spikes.
Faster Iteration
A headless architecture lets design and commerce teams ship in parallel, so changes go live without a full redeploy of everything.

Frequently Asked Questions
Straight answers about how we work.
What e-commerce platform does OOZOU build on?
Medusa.js, an open-source headless commerce platform, with Next.js, TypeScript, PostgreSQL, and Stripe. You own the entire stack and pay no per-order license fees.
Why headless commerce instead of a hosted platform?
Headless fits brands that need a storefront that fits exactly, custom checkout flows, or deep integrations. If a hosted platform fits your needs, we will say so; if you have outgrown one, headless on Medusa.js removes the ceiling and the transaction fees.
Can OOZOU migrate our existing store?
Yes. We migrate catalogs, customers, and order history, keep URLs and SEO intact, and run the old store until the new one is proven.
Does OOZOU integrate local payment methods in Thailand?
Yes. Alongside Stripe we integrate the payment and logistics providers your market needs, including Thai payment methods and delivery services.
