## Overview

This is a C# Windows Forms order and inventory management application with customer, manager, and director roles. The visible workflow starts at the login form, then role-specific screens open customer, product, and order management forms; these forms display records and invoke module dialogs for edits or transactions. The sampled forms access a LocalDB database directly. The README also describes customer order history and director user administration, but their implementation details were not sampled, so those capabilities are shown with limited, unverified links.

Main entry points: [`MANAGEMENT SYSTEM/DIRECTORHOME.cs`](https://github.com/azazkaif/pharmacuticals-company-stock-and-sells-management-system/blob/master/MANAGEMENT%20SYSTEM/DIRECTORHOME.cs) (Director home), [`MANAGEMENT SYSTEM/MANAGERHOME.cs`](https://github.com/azazkaif/pharmacuticals-company-stock-and-sells-management-system/blob/master/MANAGEMENT%20SYSTEM/MANAGERHOME.cs) (Manager home), [`MANAGEMENT SYSTEM/LOGIN.cs`](https://github.com/azazkaif/pharmacuticals-company-stock-and-sells-management-system/blob/master/MANAGEMENT%20SYSTEM/LOGIN.cs) (Login), [`MANAGEMENT SYSTEM/OrderForm.cs`](https://github.com/azazkaif/pharmacuticals-company-stock-and-sells-management-system/blob/master/MANAGEMENT%20SYSTEM/OrderForm.cs) (Director orders)
