## Overview

PAYOO is a browser-based mobile-finance interface. The main journey is login to the home dashboard, where users switch between account services; add-money, cash-out, and bonus scripts update the displayed balance and append transaction-history entries. The README also documents money transfer and bill payment, though their implementation is not shown here. The supplied excerpts show DOM-backed state rather than a separate backend or persistent store, so undocumented service wiring is omitted.

Main entry points: [`scripts/machin.js`](https://github.com/sabbirvuia/payoo-mfs/blob/main/scripts/machin.js) (Section Navigation), [`scripts/add-money.js`](https://github.com/sabbirvuia/payoo-mfs/blob/main/scripts/add-money.js) (Add Money), [`scripts/cash-out.js`](https://github.com/sabbirvuia/payoo-mfs/blob/main/scripts/cash-out.js) (Cash Out), [`home.html`](https://github.com/sabbirvuia/payoo-mfs/blob/main/home.html) (Transaction History)
