Invoices, P&L and customers — one mini app

An operations mini app for an AC service and maintenance company, running entirely inside Telegram: live profit and loss, invoicing with PDF documents, customer records and collections — all from the owner's phone.

The context

Regional Engineering is an AC service and maintenance company. Its operating reality is the same one most Maldives service businesses share: jobs arranged by phone, invoices assembled by hand, and the owner's picture of the month living in a notebook and a bank statement.

The problem, in the owner's words

Who owes us money right now — and are we actually profitable this month? Answering that meant collecting numbers from paper invoices and memory. By the time the answer existed, it was out of date.

What we built

  • A Telegram mini app — nothing to install, works on any phone the team already carries
  • Live dashboard: net profit, sales, collections, outstanding balances
  • Customer records with per-customer history
  • Invoice creation with professional PDF documents generated on demand
  • Invoice status tracking: paid, unpaid, partial, overdue
  • Secure cloud database with role-restricted access

Why it matters for hospitality

The machinery is the same one an island property needs: records in, documents out, live numbers on the owner's phone. A variant of this system runs reservations at the 32-room property we help operate. Custom builds like this are scoped through paid Discovery ($350) and start at $1,200 — see Systems & Automation.
