Description
In this video, we build Purchase Payments for our inventory management system in Laravel 13. For every purchase, you can add payment data, and once the full due amount has been paid, the purchase status changes automatically from Pending to Completed.
A purchase can be paid in many instalments, so every payment is saved as its own row. The paid amount, due amount, and status of the purchase then update on their own whenever a payment is added, edited, or deleted. This is a Laravel Filament 5 tutorial, and it introduces a new Filament feature for this series: the Relation Manager, which shows the payments table inside the purchase 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.
