Commerce platforms connected to your business systems

We build commerce systems with Shopify or MedusaJS, depending on the business model, integrations and operational requirements.

For smaller businesses and straightforward online sales, Shopify provides a stable platform with short implementation cycles and established operational tooling.

For more complex commerce setups, we use MedusaJS as a flexible, open-source foundation for custom storefronts, business logic and system integrations.

Why Shopify

  • established commerce platform
  • short implementation cycles
  • integrated tools for managing online sales
  • broad ecosystem of apps and connectors

Why MedusaJS

  • open-source headless commerce platform
  • flexible storefronts and business logic
  • API-first architecture
  • suitable for integration-heavy environments

Integration with existing systems

Commerce systems rarely work in isolation. We connect them with ERP, CRM, fulfilment and other operational systems.

For straightforward Shopify setups, standard connectors or middleware may be sufficient.

For more complex environments, a dedicated integration layer can keep systems loosely coupled and reduce the impact of changes across the application landscape.

Depending on the requirements, we use established integration tools or build custom services with Node.js.

Development approach

We focus on reliable storefronts, maintainable integrations and clear operational workflows.

Where suitable, we prefer proven open-source technologies, efficient infrastructure and European hosting.
