## Overview

POS Codekop is a PHP/MySQL point-of-sale application for a small retailer. An admin signs in, enters the routed dashboard, manages products and categories, then uses the AJAX cashier to build a cart and complete a transaction; the result is stored as a numbered sale and can be printed. Separate admin pages support reporting, store settings, and user-profile management, with Excel/PDF exports. The graph follows the README and sampled entry points; several subsystem connections are documented but their implementation was not sampled, so uncertain call wiring is omitted.

Main entry points: [`index.php`](https://github.com/fauzan1892/pos-kasir-php/blob/master/index.php) (Admin router), [`admin/module/barang/index.php`](https://github.com/fauzan1892/pos-kasir-php/blob/master/admin/module/barang/index.php) (Product management), [`fungsi/edit/edit.php`](https://github.com/fauzan1892/pos-kasir-php/blob/master/fungsi/edit/edit.php) (Edit operations), [`admin/module/kategori/index.php`](https://github.com/fauzan1892/pos-kasir-php/blob/master/admin/module/kategori/index.php) (Category management)
