StackPlus POS

The Problem

Small F&B businesses (warungs, cafes, coffee shops, cloud kitchens) mostly record sales by hand or use simple cashier apps disconnected from stock. Owners don't know their real-time ingredient stock, so they run out suddenly or overstock and waste food. Cash discrepancies are hard to trace to a specific cashier or shift. Menu-level HPP (cost of goods sold) is unknown because recipes aren't tracked, and there is no data on best sellers or peak hours.

Our Solution

NusaKasir is a subscription-based POS + Inventory platform. The Android POS app runs on a cashier tablet, works offline and syncs automatically when the connection returns. The web dashboard lets owners manage menus, recipes, stock and reports from anywhere. Recipes (Bill of Materials) link every menu item to its ingredients, so each sale deducts stock automatically and HPP per menu is always up to date. Role-based access keeps cashiers on operations while owners keep full control.
