E-commerce Stores with Medusa.js — More Control Than Any SaaS Platform
I design and build e-commerce stores on Medusa.js — a modern, open-source e-commerce backend written in TypeScript. This is a solution for projects that need custom logic, real integrations, and room to grow — without being locked into a closed platform ecosystem.

Problems I solve
You're planning to grow and don't want to rebuild everything in two years
Shopify limits your checkout, pricing logic, or integrations — and every extra feature costs more
WooCommerce works at first, but grows into a tangle of plugins that's hard to maintain
You need custom product variants, pricing rules, or order flows that standard platforms can't handle
You want to own your code and infrastructure — not rent access to someone else's platform
Costs and amount of plugins of classic platforms are too much for you?
What you get
Every project element is carefully refined. I turn ideas into solid, scalable solutions, ensuring the highest quality at every stage.
Medusa.js backend — configured for your store model
Storefront (frontend) — built to your design or an agreed template
Product catalog, variants, and inventory setup
Checkout flow — standard or custom
Payment integration (if in scope)
Hosting and deployment configuration
Git repository and full access handed over to you
Basic handover and training session
Process
Discovery call — I learn your store model, product types, and business requirements
Requirements analysis and MVP scope — we define what's standard and what needs custom logic
Architecture and estimate — I propose a technical approach and a clear price
Implementation — backend, frontend, integrations, checkout
Checkout testing — payments, order flows, edge cases
Deployment and handover — hosting, repository, credentials, training
How this service works in practice
Who is a Medusa.js store for?
This is a good fit if your project needs at least one of the following:
- Custom product logic — unusual variants, pricing rules, or order flows
- Freedom in development of your shop and business
- Integrations with external systems — ERP, CRM, logistics, custom payment providers
- A store that will grow — and you don't want to rebuild it in two years
- Full ownership of the codebase and infrastructure
- A modern TypeScript backend — not a plugin-based system held together with duct tape
When Medusa.js doesn't make sense
I'd rather tell you this upfront than take on a project that's wrong for both of us.
- You need the cheapest possible store and want it live in days — Shopify or WooCommerce will serve you better
- You don't need any custom features — a standard template and default checkout are enough
- You don't want to manage your own infrastructure — a hosted SaaS platform removes that responsibility
- Your budget is very limited and you're not planning any development after launch
Medusa.js vs Shopify vs WooCommerce — an honest comparison
Shopify
A solid choice for a simple, fast start. Hosted, maintained, with a large app ecosystem. The trade-off: customization has limits, every extra feature usually means another monthly subscription, and your checkout and pricing logic are constrained by what the platform allows.
WooCommerce
Popular and cheap to start. Works well for simple stores. As complexity grows, it tends to accumulate plugins, performance issues, and maintenance overhead. Not a bad choice — but it has a ceiling.
Medusa.js
Open-source, TypeScript, API-first. You own the code. You can build custom checkout flows, pricing logic, and integrations without being constrained by what a plugin marketplace offers. More setup work upfront — but no artificial ceiling on what you can build.
What you can build
Within the scope of a Medusa.js store project, I can build:
- B2C or B2B store
- Product catalog with custom variants and attributes
- Custom pricing logic — tiered pricing, customer groups, promotions
- Custom checkout flow
- Payment integrations (Stripe, Przelewy24, and others)
- Integrations with external systems — ERP, CRM, logistics, warehouse
- Order and inventory management
- Transactional emails, discount codes, returns handling
I know Medusa.js from production, not just documentation
I use Medusa.js in my own actively developed e-commerce project — a production system with real users and real orders. That means I've dealt with the practical side of the technology: deployment, hosting, feature development, maintenance, and the decisions that only become obvious when you're running a live system. When I build your store, I'm not learning on your project.
You work directly with the person building it
AppCrates is not a large agency. There's no account manager between you and the developer. You talk directly to the person who designs the architecture, writes the code, and makes the technical decisions. That means faster feedback, clearer answers, and no information lost in translation.
Frequently asked questions
Sometimes yes, sometimes no. If your store is very simple — a handful of products, standard checkout, no custom logic — Shopify or WooCommerce may be a cheaper and faster start. Medusa.js makes more sense when you need flexibility, custom processes, or plan to grow beyond what a SaaS platform allows.
Medusa.js is open-source, so the software itself has no license cost. But building, hosting, and maintaining a store on it requires development work and infrastructure. You're paying for the implementation, not the platform.
It depends on scope: number of integrations, checkout complexity, frontend design, custom pricing logic, and any additional features. I'll give you a concrete estimate after a discovery call — not a vague range.
Yes. Medusa.js works well with a headless architecture, so the frontend is completely separate. You can use Next.js, Remix, or any other framework — or I can build it as part of the project.
Yes. The code, repository, and all credentials are handed over to you at the end of the project. You're not renting access — you own the platform.
Yes, but that's a separate, more complex service. This page covers e-commerce stores. If you're thinking about a multi-vendor marketplace, let's talk — it's a different scope and a different conversation.
Yes. Payment integration can be included in the project scope. Medusa.js has built-in support for Stripe and other providers, and custom integrations are possible.
Yes. Ongoing maintenance and development are available as a paid service. I can help with bug fixes, new features, or infrastructure as your store grows.
Yes. I can migrate your product catalog, customer data, and order history. The scope and effort depend on how much data you have and how it's structured — we'll assess it during the discovery phase.
