The Challenge: Outdated Legacy System
SmartRetail, a growing retail chain in Germany, was running on a 10-year-old Windows-based POS system. It was slow, crashed frequently, and couldn't handle their expansion plans.
The old system didn't sync between stores, making inventory management a nightmare. They needed a modern, cloud-based solution that could scale with their growth.
The Solution: Cloud-Based POS with Real-Time Sync
We built a progressive web app (PWA) using Next.js and TypeScript that works on tablets and works offline when internet drops.
Backend: .NET Core API with PostgreSQL database hosted on Azure. Real-time inventory sync across all locations using WebSockets.
Migration: We ran both systems in parallel for 2 weeks, ensuring zero data loss and training staff before the complete switch.
Added features: Real-time sales analytics, automated stock alerts, and customer purchase history.
The Results: Faster Operations and Better Insights
Checkout times dropped by 40%, and inventory discrepancies between stores were eliminated. The owner can now see real-time sales data from anywhere.
Thomas Mueller, the founder, said: 'Finally found developers who understand modern tech stacks. They migrated our legacy system to a fast, cloud-based solution. Worth every penny.'
