Case Study: POS system for a fast-growing Dutch beer & snack bar chain
We developed a modern custom POS system tailored for counter-service-only bars. The system supports three roles: Cashier, Branch Manager, HQ Manager, and features fast tap-based ordering, shift tracking, multi-location menu update, real-time branch performance monitoring, and centralized price management.

About the Client:

Location:Netherlands
Industry: Hospitality / Food & Beverage
Team size: 6 specialists (1 PM, 1 BA, 2 developers [frontend + backend], 1 UI/UX, 1 QA)
Project duration: 4.5 months
Business сhallenge
Build a tailored responsive POS system that:
- allows for rapid order-taking and payment at the counter;
- enables easy shift management;
- supports centralized menu management for multiple locations;
- provides centralized operations oversight.
Our solution
We developed a modern, high-speed POS system built for touchscreen terminals and integrated with receipt printers, cash drawers, and card terminals. The solution supports Cashier, Branch Manager, and Head Office manager roles with granular access controls, centralized menu and pricing management, offline order queueing, real-time multi-branch reporting, and robust shift tracking.
Testing under real conditions
To ensure proper hardware compatibility, the Client shipped a full terminal setup to our office — including receipt printer, card reader, and cash drawer – which allowed us to develop and test in real conditions from the very beginning.
So we were able to run end-to-end validation of receipt printing, cash drawer triggers, Zettle integration, offline sync, and role-based actions – ensuring the system performs reliably during high-volume rush hours.
Additional features:
- role-based access;
- Head Office Manager dashboard with real-time sales analytics;
- offline mode with auto-sync;
- multi-location menu syncs;
- time-based pricing;
- combo deals management;
- managing user accounts and permissions.
Business value
Before:
- Long lines during peak Friday evenings because cashiers struggle with slow order entry.
- Customers frequently complained about ordering items that turned out to be unavailable, since the
- system doesn’t allow for flagging out-of-stock products.
- Menu updates were pushed branch by branch using USB sticks or manual entry.
- When internet outages occurred, bars had to switch to pen-and-paper tickets, causing lost orders and payment errors.
- Head Office staff depended on end-of-day emails from each branch to compile total sales.
After:
- Fast tap-to-sell cashier interface speeds up order entry, reducing lines even during the busiest Friday nights.
- Branch managers can instantly hide out-of-stock items.
- Menu changes and pricing updates are pushed from Head Office and sync automatically to all branches in seconds.
- Offline mode keeps order-taking and payments running smoothly during internet outages, with automatic data sync afterward.
- Head Office tracks real-time multi-branch sales and performance from a centralized dashboard, no manual compilation needed.
