PROJECT

PATOGH

Café Accounting & POS System

A desktop café management and accounting system covering sales, purchases, inventory, expenses, cash flow, and reporting — with remote monitoring over IRC.

  • Python
  • PyQt6
  • SQLite
  • IRC
  • Desktop

INTERFACE

PATOGH café accounting and POS interfaces covering the dashboard, sales entry, inventory management, and reporting views.

PATOGH cafe accounting dashboard showing sales, purchases and inventory at a glance
PATOGH sales and transaction entry interface for recording cafe orders
PATOGH inventory and product management with stock levels and pricing
PATOGH reports and accounting summaries covering sales, purchases and expenses

PROBLEM

Small cafés run on paper notebooks and memory. Sales, stock, and purchases are untracked, costs are invisible, and the owner cannot see the day's activity without being physically present at the counter.

APPROACH

Build a complete operational system around a normalized SQLite schema, expose it through a PyQt6 desktop interface, and push important events to a remote IRC channel so activity is observable from anywhere.
