Core PHP Billing + Inventory Management

I'm in need of a full-fledged Billing and Inventory Management System (IMS) web application using Core PHP. This application is intended to streamline various aspects of my business and I hope to incorporate the following features: - **Inventory Management:** The system should allow me to keep track of my inventory levels, manage stock, and generate inventory reports. - **Sales Tracking:** One of the key functionalities I seek is the ability to log and track sales. This should include details like date of sale, item sold, quantity, and pricing. - **Customer Management:** The system should enable me to manage my customer base. This includes keeping records of customer orders, contact information, and any other useful data. - **Profit and Loss:** The application should provide insights into my business performance by calculating profits and losses based on inventory, sales, and other financial data. - **Accounts:** I expect it to have the capability to create, manage and generate various financial reports related to the transactions and accounts. Ideally, the system should be well structured, user-friendly, and secure. I'm looking for a freelancer with experience in Core PHP development, particularly in e-commerce and inventory management systems. Prior experience with similar projects will be a plus.
