Everything Medusa, under one roof

A headless build is a platform decision, a design project and an engineering project at once, and it only pays back when all three are planned together. Our strategists, designers, Medusa developers, integration engineers and growth specialists work as one team, from the first decision on the platform to the store running day to day.

What we do on Medusa

Commerce you own

On a hosted platform you rent the store. The platform decides what checkout can do, which apps you need for the rest, and what each of them costs every month. Medusa turns that round. It is open source, so the code runs on servers you choose and the store, the data and every line built for it belong to you. Medusa itself takes no fee from your sales.

Underneath, Medusa is a set of commerce modules (products, carts, orders, pricing, stock, customers) built in TypeScript on Node.js, with an admin your team uses every day and can be extended for your own work. Anything the business needs that Medusa does not do out of the box is built into the platform itself, never bolted on from outside.

Is Medusa the right choice?

Medusa is not for every store, and we say so in the audit. We build on Shopify and Magento as well, so the recommendation follows the business.

Medusa is the right base when:

  • The business runs on rules a hosted platform cannot hold: pricing, bundles, stock or order routing of its own
  • You sell to trade buyers, or run a marketplace with many sellers
  • You sell in several countries or brands from one set of products and stock
  • Owning the platform matters more than having a ready-made one

Where a well-built Shopify store would do the job, that is what we recommend, with a headless build kept for the point where the business outgrows it.

Headless storefronts in Next.js

Headless means the storefront your customers see is built on its own, apart from the platform that runs products, checkout and orders behind it. That gives the design complete freedom and the pages real speed, because nothing on them is there for a theme’s sake.

Our designers work from research into how your customers choose and buy, with desktop and phone designed together and signed off before the build. Our developers build the storefront in Next.js on Medusa’s storefront tools, with pages rendered on the server so they load fast and Google reads them in full.

  • Desktop and phone designed together, signed off before the build
  • Pages rendered on the server, fast on a phone
  • Content from a separate CMS where you need one
  • Checkout built for your customers, in your brand

Custom commerce logic

This is where Medusa earns its place. Its workflows run each step of a process in order, retry a step that fails and roll back cleanly if the process cannot finish, so an order is never left half done.

Our developers build the logic your business depends on as modules and workflows inside Medusa, for jobs like:

  • Prices by customer group, region or quantity, worked out the same way everywhere
  • Bundles and kits that take the right stock from each part
  • Stock held across several warehouses, with each order sent from the right one
  • Returns, exchanges and refunds that follow your own rules
  • Product data shaped for each marketplace from one record

B2B and marketplaces on Medusa

For B2B we set up company accounts with several buyers each, quotes, spending limits and approval steps, so trade buyers order online on terms that match how they buy offline. For marketplaces we build stores where many sellers list their own products, take their own orders and see their own payouts, with you running the store above them. Both run on the same Medusa store as your retail customers when you need them to.

Moving to Medusa without losing your rankings

A move to Medusa, from Magento, WooCommerce or Shopify, is judged on what customers and Google notice: every product there, customers who can still sign in, and old links that land somewhere useful.

Every move follows the same five steps:

  1. 1Products, customers, orders, content and every old address mapped before anything is built.
  2. 2The new store built and filled alongside the old one, which keeps trading.
  3. 3A redirect for every old link, with page titles and content carried across.
  4. 4The two stores tested side by side, page by page and order by order.
  5. 5The switch timed around your trading days, with the old store kept ready as a way back.

Medusa joined to the rest of the business

A Medusa store is built to be joined to everything else, and that is where most headless projects fall short. Orders from eBay and Amazon, stock in the warehouse system, money in the accounts: if the joins are an afterthought, a store with a beautiful front end still oversells and still loses orders.

With 50+ channel integrations behind us, we join Medusa to:

  • eBay and Amazon, with one catalogue and one stock figure across every channel
  • Linnworks and other order and warehouse systems, so every order is picked, packed and sent from one place
  • Xero and your ERP, with sales, fees and refunds matched in the accounts
  • Klaviyo, with the order and product data your emails need
  • Payments, couriers and the rest of what the business runs on

Every connection is watched, with an alert when one fails, and one system is in charge of each number.

Hosting and running Medusa

Owning the platform means someone has to run it, and we do. We host on Medusa Cloud, Medusa’s own managed hosting, or on your own cloud account where you need it. Either way the store has a copy to test every change on, releases that go out without taking the store down, backups, and Medusa’s updates applied and tested before they reach your customers.

Search on a headless store

Headless stores have a reputation for losing search traffic, and it is earned when search is left until the end. We build it in from the start: pages rendered on the server, clean addresses, structured data on every product and category, redirects in place before launch, and speed measured on a phone. Our growth team then runs content, search and shopping ads, and email that brings customers back, as one plan from your own numbers.

AI agents inside your Medusa store

Medusa is built to have agents working inside it, through its admin and its workflows. We put them to work on the routine jobs: product data written in your brand’s voice, stock and prices checked across your channels, problem orders flagged, and customer service replies drafted with the order already looked up. Your team’s time goes on the decisions.

No agent changes your store on its own. Every change is a dry run first, you approve it, the store is backed up before anything is applied, and every change is logged so it can be put back. Agents never delete.

See how our AI agents work

Five steps behind every agent

  1. Dry runSee every change first.
  2. Your approvalNothing moves until you say.
  3. BackupEverything saved before a change.
  4. ApplyOnly what you approved.
  5. LogEvery change can be put back.

Agents never delete.

Managed eCommerce on Medusa

A headless store needs a team behind it after launch, and through Managed eCommerce we are that team. A senior team runs the platform and the store month after month: updates, hosting, new features and fixes, alongside the trading work of products, promotions and listings, with a monthly report against agreed targets. One accountable lead knows the code, the store and the business behind them.

Questions about Medusa

Book a call
  • Is Medusa right for us, or should we stay on Shopify?

    If a well-built theme does the job, stay on Shopify. Medusa is for businesses whose pricing, stock, B2B or marketplace needs have outgrown what a hosted platform can hold. We build on both, and the audit shows which side of the line you are on.

  • What does Medusa cost to run?

    Medusa itself has no licence fee and takes nothing from your sales. The running costs are the hosting and the team that looks after the store, and the audit sets them out against what you pay for the platform and apps today.

  • Do we need our own developers?

    No. We build the store and run it for you through Managed eCommerce, and the code is documented so your own team, or another, could take it on later.

  • Will a headless store hurt our search rankings?

    Not when search is built in from the start. Pages are rendered on the server, every old link gets a redirect, and structured data goes on every product and category before launch.

  • Can Medusa work with our ERP, warehouse and marketplaces?

    Yes. We join Medusa to eBay, Amazon, Linnworks, Xero, your ERP and the rest of what the business runs on, then watch every connection.

  • Who owns the store and the code?

    You do. Medusa is open source, the code we build lives in your own repository, and the store and its data are yours.

  • Is it safe to let AI agents work on our store?

    They cannot act on their own. Every change is a dry run first, approved by you and backed up before it is applied, and agents never delete.
