Invoice Management System – Oracle APEX

This screen is an Invoice Management page (Create/Edit) built using Oracle APEX. It includes invoice details, payment calculations, and a dynamic grid for managing products with quantities and prices.

The page uses Dynamic Actions with JavaScript to perform real-time calculations (totals, discounts, and taxes) and enhance user interaction without page reload.

It also follows a Master-Detail structure, providing a smooth and efficient user experience for managing sales invoices.
