Coffie House (بيت البن) — Coffee Roastery POS System

A coffee shop running on notebooks and spreadsheets needs one offline system that closes the loop between raw barrels, retail grind sales, drink orders, wholesale credit, expenses, and daily cash reconciliation — installed once with zero cloud dependencies. Every sale, expense, and shift is linked to a single active shift, reconciled on close, and written to an audit trail, so the drawer count, the ledger, and the reports finally agree. It ships as a native Windows installer (Electron with embedded MongoDB) that orchestrates three processes (Electron main → mongod.exe → compiled Express backend). Includes 53 REST endpoints, 11 Mongoose models, 4 roles, JWT auth with revocable sessions, bilingual Arabic/English UI, and ESC/POS thermal printing.
