MedusaJS development for your commerce platform
For agencies and brands that have chosen MedusaJS. We set up the product structure, build the storefront and integrations, and keep developing the platform.
Why this approach
Product structure in Medusa
We set up products, variants, prices, regions and sales channels to match how you sell. You get the model in writing before the build.
Custom modules, not forks
When you need logic Medusa does not ship with, we write it as a module or workflow in TypeScript. The core stays untouched, which keeps upgrades simpler.
Storefront and content
We build the storefront in Next.js, connected to Medusa for products, carts and orders. Editorial content can live in Sanity, next to the product data.
Development after launch
You host MedusaJS yourself, so someone must keep it updated. We stay on for upgrades, new features and upkeep, or hand over to your team.

Questions
Should we choose Shopify or MedusaJS?
Shopify suits teams that want a hosted platform and a large app ecosystem. MedusaJS suits custom commerce logic and teams that want to host the backend, but it needs development after launch. If the choice is still open, our web development consultancy can help you decide.
Can you join an existing MedusaJS project?
Yes. We work in repositories that other teams started, and we keep to the conventions that are already there. We start by reading the modules, the data model and the integrations.
What do you build with MedusaJS?
The product structure, custom modules and workflows, the integrations and the storefront. House of Massive is a headless project on Next.js, MedusaJS and Sanity.
Can MedusaJS connect to our PIM or ERP?
Yes, through integrations that we build and test with you. We agree which system owns products, stock and orders, and what happens when a sync fails. Our headless e-commerce page covers this product data work.
Who hosts and maintains MedusaJS?
You do, on a cloud provider you choose, because MedusaJS is open source and self-hosted. We set up hosting with your team and can stay on for upgrades and upkeep. Most clients keep working with us after launch.
How do we start?
Use the contact page or write to hi@adeptive.se, in English or Swedish. Tell us about your products, the systems Medusa must connect to and your timing. We reply with our questions or a time to talk.
