Boost Coffee — QR Menu
A digital QR menu built for a café in Sarajevo — fast, multilingual, and no need to reprint the menu every time a price changes.
Problem
The café needed a menu that's easy to update — no reprinting every time a price or product changes — with fast mobile loading and support for guests who don't speak Bosnian.
Solution
We built a static, fast QR menu platform: the owner updates prices and products through a simple JSON file with no rebuild required, and guests scan the QR code to instantly see the menu in their language.
Outcome
The café now updates prices and offerings itself within minutes, with no dependency on a developer or print shop. The menu loads fast even on older phones, with WhatsApp and location buttons built into the bottom bar.
About the project
Boost Coffee is a café in Sarajevo that needed a digital menu that wouldn’t require a reprint every time a coffee price changed or a new product was added. Instead of a classic printed menu or an expensive database-and-server system, we built a lightweight, static platform the café updates itself.
How it works
A guest scans the QR code on the table or at the entrance and instantly gets a fast, mobile-optimized menu — no app download required. Behind the scenes, the platform is a single Next.js application that can serve multiple different clients (cafés, restaurants, bakeries) from the same codebase: each client has its own JSON file for products, prices and translations, fully decoupled from the application code itself.
That means the Boost Coffee owner can change the price of an espresso or add a seasonal item with a simple FTP upload of a JSON file — no calling a developer, no rebuild, and no printing cost for a new menu.
The platform supports Bosnian and English, displays allergens and nutritional info, and offers quick actions at the bottom of the screen: call, WhatsApp, directions to the location, and the café’s Wi-Fi details.
