Medusa.js stores — when Shopify is no longer enough
I design and build e-commerce solutions on Medusa.js — for businesses that need more control than off-the-shelf SaaS platforms offer. It's the right choice when a store requires custom pricing logic, a custom backend, complex integrations, B2B models, or headless architecture.

Problems I solve
Shopify or WooCommerce limits your sales model, checkout, or pricing logic.
You need custom pricing, customer groups, discounts, B2B rules, or a non-standard order process.
You're building a store that needs to integrate with ERP, PIM, WMS, accounting systems, logistics, or a custom backend.
You want full ownership of your code, data, and infrastructure instead of renting access to a closed platform.
A standard online store is no longer enough — your project is starting to look more like an e-commerce product than just a catalog with a checkout.
You don't want to solve complex requirements through more plugins, workarounds, and monthly subscriptions.
What you get
Every project element is carefully refined. I turn ideas into solid, scalable solutions, ensuring the highest quality at every stage.

How this service works in practice
Medusa.js is not a "cheaper Shopify". It's an open-source e-commerce backend for projects that need more control over sales logic, data, and integrations. It gives more flexibility than a SaaS platform, but it also requires more responsibility: hosting, maintenance, updates, and thoughtful architecture.
That's why I don't recommend Medusa for every store. If you need a simple store with a ready-made checkout and a fast launch, Shopify will usually be the more sensible choice. Medusa.js makes sense when off-the-shelf platforms start constraining your business model.
When is Medusa.js a good choice?
Medusa.js is worth considering when:
- Your store requires custom pricing logic, promotions, variants, or order processes.
- You sell B2B and need individual rules for customers, groups, price lists, or order approvals.
- You're integrating e-commerce with ERP, PIM, WMS, logistics, accounting, or your own internal systems.
- You're building an e-commerce product that will be developed in stages — not a one-time store on a ready-made theme.
- You want full ownership of your code, data, and infrastructure.
- You need an API-first backend that can connect to your own frontend, web application, or other sales channels.
When Medusa.js is not the right choice
Medusa.js is probably not the best fit if:
- You want to launch a simple store as quickly as possible without a large technical budget.
- You sell standard products and a ready-made theme, standard checkout, and basic integrations are enough.
- You don't want to deal with hosting, updates, monitoring, or technical maintenance.
- You're not planning to develop the platform after launch and don't need custom logic.
- A fixed Shopify subscription is less of a problem for you than the cost of custom development.
In that case, Shopify Development may be the better choice — especially if the goal is a fast market entry and simple store management after launch.
When will Shopify be better?
Shopify is the better choice if your main priority is a fast store launch, a simple admin panel, a ready-made checkout, and a lighter technical maintenance burden. It's a good direction for stores with a classic product catalog, standard B2C sales, and a team that wants to manage the store independently after launch.
If your requirements fit within a ready-made platform, there's no point in overpaying for a custom backend. In that case, take a look at Shopify Development.
Medusa.js vs Shopify vs WooCommerce — an honest comparison
Shopify
Shopify is best when you want to launch a store quickly and use a hosted platform that handles infrastructure, checkout, security, and updates. The trade-off is limited control over the backend, checkout, and data model.
WooCommerce
WooCommerce is a good choice for simple WordPress-based stores, especially when the starting budget is limited. With more integrations, plugins, and customizations, maintenance costs can grow quickly.
Medusa.js
Medusa.js makes sense when e-commerce is part of a larger product or business process. It gives more control over sales logic, integrations, and data — but it requires its own infrastructure, development, and ongoing maintenance.
What can you build with Medusa.js?
Within a Medusa.js project, you can build:
- a B2C or B2B store with custom sales logic,
- a headless storefront connected to the Medusa.js backend,
- a product catalog with custom variants, attributes, and relationships,
- custom price lists, customer groups, promotions, and discount rules,
- a checkout tailored to your sales model,
- integrations with payments, shipping, ERP, PIM, WMS, CRM, or internal systems,
- an operations panel for managing products, orders, and customers,
- a foundation for a marketplace or multi-vendor platform, if the project requires that architecture.
What to consider before choosing Medusa.js
Medusa.js gives you more control, but it doesn't remove technical responsibility from the project. You need to plan for backend hosting, a database, deployment, monitoring, backups, dependency updates, and ongoing maintenance. That's not a problem if the project genuinely needs the flexibility. It is a problem if the store was supposed to be simple, affordable, and low-maintenance.
Before starting a project, it's worth clearly answering one question: does the additional flexibility of Medusa.js justify the higher cost of implementation and maintenance? If not, Shopify will be the better choice.
I know Medusa.js from production, not just documentation
I use Medusa.js in my own actively developed e-commerce project — with real users, orders, hosting, and maintenance. That means I know not just the documentation, but also the practical decisions: deployment, feature development, updates, integrations, and the problems that only surface when working with a live system. When I build your store, I'm not learning Medusa on your project.
You work directly with the person building it
AppCrates doesn't operate like 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.
Is Medusa.js the Right Choice?
Medusa.js offers far more flexibility than hosted e-commerce platforms, but it also requires more technical ownership. This table helps determine when Medusa.js is the right investment and when Shopify may be the better option.
Frequently asked questions
Usually not, if the store is simple and doesn't require custom logic. For a small store with a classic catalog, standard checkout, and a limited budget, Shopify will most often be the cheaper and faster choice. Medusa.js makes sense when even a smaller store has an unusual sales model or plans to grow beyond the constraints of SaaS platforms.
Medusa.js is open-source, so the software itself has no license cost. But no license doesn't mean no costs. Building, hosting, maintaining, updating, and developing the store require development work and infrastructure. You pay for the implementation and maintenance, not for access to the platform.
It depends on scope: number of integrations, checkout complexity, frontend design, custom pricing logic, and additional features. I prepare a concrete estimate after a requirements analysis — because in Medusa.js, the biggest cost drivers are integrations, custom logic, and the scope of ongoing maintenance.
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 a marketplace is a separate category of project — not just a store with an extra feature. It requires handling multiple sellers, commissions, payouts, permissions, moderation, and often a more complex admin panel. If you're building a marketplace, a dedicated multi-vendor marketplace service would be a better starting point.
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.
