Ecommerce development on Shopify and Medusa

We design and build online stores on Shopify when you want the platform to run the hard parts, and on Medusa when the way you sell needs custom logic. Both with fast storefronts, content your team can edit, and code and accounts in your name.

Which platform fits your store

We build on both, so the recommendation follows your store, not our preference.

  • Shopify with a custom theme

    For most stores: a catalogue, a checkout and a brand that should look like no one else. Quick to launch, simple to run, and Shopify handles hosting and updates.

  • Headless Shopify

    Shopify’s checkout and orders behind a Next.js storefront, with editorial content in Sanity. For brands where content, speed or several markets matter as much as products.

  • Medusa

    Open-source commerce for stores whose pricing, checkout rules or back office don’t fit a standard platform. You own the code and pay no platform fee per order.

Stores we have built

Custom commerce where a template would not do.

  • VanGold

    Next.js + Medusa + Sanity

    A Vienna bullion dealer. Prices follow the live metal price, Austrian VAT and invoices are automated, and guides are edited in Sanity.

How we build a store

A platform choice you understand, a scope you sign off, and a store your team can run after launch.

  1. Audit

    We look at your products, how you price and ship, your current store if you have one, and the tools it has to work with.

  2. Platform and scope

    Shopify, headless Shopify or Medusa, with a written scope and milestones you sign off before work starts.

  3. Design

    Product pages, collections, cart and content designed around your brand and reviewed with you at every milestone.

  4. Build

    Theme or storefront, custom features, integrations and content setup, tested against real orders before launch.

  5. Launch

    Products, customers and orders moved across if you are switching platforms, every old URL redirected, and checkout tested end to end.

  6. Support

    We stay on after launch for fixes, new features and seasonal campaigns, as much or as little as you need.

Ecommerce development questions

  • Shopify if you want the platform to run hosting, checkout and updates, and your store works like most stores. Medusa if your pricing, rules or back office are the hard part and you want to own the code. We build on both and will recommend one after looking at your store.

  • Yes, with Next.js for the storefront and Sanity for content, keeping Shopify’s checkout. For many stores a custom theme is enough, and we will say so. See Shopify development.

  • Yes. We move stores from WooCommerce, Magento and other platforms, with products, customers and order history moved by script and every URL redirected.

  • Yes. Code, accounts and data are in your name. On Medusa you own the code outright and can host it anywhere; we can host it for you if you prefer, and hand everything over whenever you ask.

  • A fixed scope with milestones you sign off, by the hour, or on a monthly retainer. The audit and estimate come first and are free.

  • Yes. Fixes, updates, new features and campaign pages, on a retainer or as needed.
