Learn about the technology behind Flow Retail
Behind the scenes, it runs on a modern, modular architecture powered by APIs, cloud technology, and real-time data processing—designed specifically for retail chains and specialty stores.
With a strong focus on reliability, security, and seamless integrations with ERP systems, e-commerce platforms, and more, this page gives you a technical overview of what powers Flow Retail.
MACH compliant
Flow Retail is 100% MACH-compliant — built to meet the demands of future-focused retailers with a modern, flexible, and scalable architecture.
- M (Microservice) – Flow Retail has micro services as part of the suite, like the Flow Gift Card service – fully standalone yet still fully integrated with the Flow Retail POS platform.
- A (API-first) – When building new features we always define and build the APIs first, and then we build the functionality and logic itself.
- C (Cloud-native, or Composable) – Flow Retail is born in the cloud, ready to be connected with anything.
- H (Headless) – Our clients (frontend) are totally disconnected from the backend (Flow Retail Core), utilizing the APIs at full, and with little to no logic in the client themselves.
Decoupled architecture – as it should be
Flow Retail is built with a fully decoupled architecture, where business logic and clients are completely separated. Our own apps and interfaces use the same public API as any external integration partner—ensuring openness, flexibility, and consistency across all channels.
The building blocks of modern retail
- Flow Retail Core – the platform itself – is built in Go, one of the most reliable and high-performance programming languages in the world.
- All servers run on Linux, with PostgreSQL as the database engine.
- Our apps for Windows, Mac, tablets, and handheld devices are developed in Dart and Flutter, a leading cross-platform framework used by millions of developers.
- The Backoffice interface runs in the browser and is developed using React and TypeScript, enhanced with modern UI components like Shadcn and Tailwind CSS.
- All our APIs follow the OpenAPI standard, making integration fast, predictable, and developer-friendly.
