Complete OSS/BSS platform transforming ISP billing and operations nationwide
The Challenge
What we were solving.
National ISPs across Bangladesh were running on spreadsheets, WhatsApp groups, and manual billing cycles. Subscriber management was error-prone, revenue leakage was endemic, and BTRC regulatory compliance was an afterthought.
RADIUS authentication -- the backbone of subscriber access control -- was configured manually on each Mikrotik router. Adding or suspending a subscriber required SSH access to network hardware, creating security risks and operational bottlenecks.
Mobile financial services (bKash, Nagad) had become the primary payment method for subscribers, but no billing platform supported automated reconciliation with these providers. Collection rates hovered around 60-70%.
What We Built
Technical architecture.
A full OSS/BSS platform in Go, purpose-built for the Bangladeshi ISP market. The system manages the complete subscriber lifecycle: provisioning, authentication, bandwidth management, billing, payment collection, and regulatory reporting.
Centralized RADIUS integration with FreeRADIUS controls subscriber access across all network hardware. When a subscriber pays, their connection is automatically activated. When a bill is overdue, access is throttled or suspended -- no manual intervention required.
Deep integration with Mikrotik routers via their API enables remote configuration, bandwidth shaping, and real-time monitoring. ISP operators manage their entire network from a single dashboard instead of SSH-ing into individual devices.
Automated billing with bKash and Nagad integration handles payment reminders, collection, and reconciliation. BTRC-compliant reporting is generated automatically for regulatory submissions.
Key Numbers

Outcome
Business results.
Over 40 ISPs have adopted the platform, replacing fragmented manual processes with a unified operations system. Collection rates improved to 90%+ for most operators.
BTRC compliance is now automatic rather than a quarterly scramble. Regulatory reports generate with a single click covering subscriber counts, bandwidth allocation, and service quality metrics.
ISP operators report 70% reduction in operational overhead, freeing technical staff to focus on network expansion rather than subscriber management.
