AK Broadband CRM (ISP Customer Management Software)

AK Broadband CRM

AK Broadband CRM is a desktop-based customer relationship management system developed specifically for internet service providers (ISPs) to manage their daily operations efficiently. The software provides a complete solution for handling customers, billing, payments, reporting, and financial tracking within a single platform.

The application is designed with a modular architecture, allowing each feature to function independently through dedicated UI components. This makes the system highly scalable, maintainable, and easy to extend with new features. It is built as an offline-first solution, ensuring reliability even without internet connectivity.

One of the key strengths of this system is its intelligent database management. The application automatically creates the database if it is missing, verifies the schema on startup, and performs necessary updates if the structure is outdated or corrupted. This eliminates the need for manual database setup and ensures smooth deployment in both development and production environments.

The CRM includes a comprehensive customer management system where users can add, update, and track customer profiles along with their assigned internet packages. It supports automated billing generation, payment tracking, and invoice management, making it easier to handle recurring monthly billing cycles.

A powerful reporting module is integrated into the system, providing insights such as revenue trends, customer summaries, package distribution, defaulter lists, and profit/loss analysis. These reports are enhanced with graphical visualizations, helping business owners make informed decisions based on real data.

The software also includes features for expense management, allowing tracking of operational costs and calculation of overall profitability. Additional modules such as backup and restore ensure data safety, while invoice customization and theme selection improve usability and presentation.

The application is developed using Python with PyQt5 for building a rich desktop user interface. It uses SQLite as a lightweight database solution, eliminating the need for external database servers. For data visualization, Matplotlib is integrated directly into the interface. The project is packaged as a standalone executable using tools like PyInstaller, enabling easy installation and use without requiring a Python environment.

Overall, AK Broadband CRM is a robust and practical solution tailored for small to medium-scale ISPs, demonstrating strong capabilities in software design, database handling, and business process automation.
