Invoice System using PHP Free Source Code

Invoice System using PHP Free Source Code

Introduction

This is a PHP project that I’d developed called Invoice System. This is a simple OOP PHP project that can help some companies to manage their invoices. The system handles invoices for both selling products and services. This system can help other programmers especially those who are new to PHP language to learn some techniques and understand how to build an Invoice System in the said programming language.

About the Invoice System

The Invoice System was developed using PHP/OOPMySQL DatabaseHTML5CSSJavascript (jQuery and Ajax), and Bootstrap. The system stores the list of categories, products, services, and invoices. The invoices that will be store or generated in this system has 2 types which are the product invoice and service invoice. The system automatically generates a random invoice code but also editable and has a validation to check the code availability. After the invoice is saved, then a new window will pop up that contains the printable generated invoice. The dashboard displays the summary of the list stored inside the database. When listing the items of products or services in creating an invoice, the system has error trapping features to prevent human errors to result in system errors.
