## Overview

This Laravel 7 point-of-sale application supports user accounts, customer and product management, checkout with stock checks and decrementing, sales reporting, and thermal-ticket printing. The primary workflow is a user building a cart, completing a sale, and later viewing or printing the resulting sale. The README also documents an API consumed by an Android app. Edges reflect the supplied controller excerpts, SOURCE INDEX references, and README; API internals and several UI/controller relationships were not sampled, so those links are omitted or marked unverified.

Main entry points: [`routes/web.php`](https://github.com/parzibyte/sistema_ventas_laravel/blob/master/routes/web.php) (Web routes), [`app/Http/Controllers/VenderController.php`](https://github.com/parzibyte/sistema_ventas_laravel/blob/master/app/Http/Controllers/VenderController.php) (Sale controller), [`routes/api.php`](https://github.com/parzibyte/sistema_ventas_laravel/blob/master/routes/api.php) (Mobile API), [`app/Venta.php`](https://github.com/parzibyte/sistema_ventas_laravel/blob/master/app/Venta.php) (Sale records)
