Description
In this video, we build Sale Payments for our inventory management system in Laravel 13. You can record payments received from customers against every sale, directly from the sale page.
A customer can pay in many instalments, so every payment is saved as its own row in a new sale payments table. The paid amount, due amount, and status of the sale then update automatically, and once the full due amount is received, the sale changes from Pending to Completed. This is a Laravel Filament 5 tutorial, and it uses the Filament Relation Manager to show the payments table inside the sale page.
This series is a free Laravel project with source code, built step by step from installation to a working inventory management software. If you are looking for Laravel project ideas, or want to learn FilamentPHP 5 properly, this Laravel project tutorial is for you.
