Cashflow OCM · Web app

One phone app, profit visible in seconds

Designed to bring my family's palm-oil supply business finances into one app: purchases from collection points, sales to the mill, cash, expenses, and tax. Works on a phone.

The challenge

Purchases from 13–16 collection points, mill sales, expenses, and tax lived in separate notebooks, chats, and spreadsheets. Profit only became clear at month-end, and payment gaps were hard to trace.

My decisions

  • 30+ screens: purchases, sales, dated reference prices, cash, expenses, P&L
  • Supplier 360 card: advances, debts & invoice age, tonnage trend, off-standard prices
  • PDF, Excel, and image reports ready for WhatsApp; VAT sheet ready for the tax portal
  • Purchase notes generated the moment a ticket is saved, ready to print via the Thermer app
  • Strict period closing, activity log, and 5 access levels (owner, admin, cashier, accountant, viewer)
  • Automatic backups, offline mode, and token-protected public invoices

Role of AI Built with AI: one AI builds, another reviews the work, and I test it myself. Inside the app, AI helps read ticket and receipt photos and answers questions about the data.

Integration

Integrated with the Thermer app: as soon as a ticket is saved, the purchase note appears and prints to a Bluetooth thermal printer in one tap. Note text is prepared specially because Thermer drops any line containing non-ASCII characters.
