An ISP Billing System: Belnet
Custom ISP CRM/ERP to manage subscribers, data plans, payments, and NAS/Radius hardware integration in one platform.

Project Overview
Customer
CEO of Belnet (ISP) seeking a unified billing and CRM to manage subscribers, payments, and network access.
Background
Rapid expansion since 2006 led to fragmented tools. Needed centralized billing, customer care, and hardware control via NAS/Radius.
Goal
Deliver a single web platform to manage plans, payments, scratch-card top-ups, and automated access control through NAS/Radius.
Solution
A single-page web application that centralizes billing, CRM, and hardware control. Subscribers manage plans and payments, while the ISP team automates provisioning and access through NAS/Radius.
Unified workflows for top-up card generation, plan changes, speed regulation, and subscriber support reduce manual work and eliminate missed/overdue payments.
Analytics dashboards surface financials, plan usage, and subscriber statistics for informed decisions and smoother operations.
