Industry Bottleneck

The Problem

Most billing and OSS platforms running today were built for a slower era. Fewer plans, fewer channels, less pressure to launch fast. Every year they get patched instead of rebuilt, until even small changes carry real risk. Teams end up avoiding changes rather than shipping them, which is exactly backwards for a business trying to compete.

Capability Matrix

What We Do

End-to-end modernization across every tier of the BSS/OSS topology.

payments

Billing and Charging

Prepaid, postpaid, and convergent billing, including real time rating and charging.

shuffle

Mediation

Collecting and processing usage records (CDRs/EDRs) from your network elements in real time.

inventory_2

Product Catalog

Plan, bundle, and pricing configuration that does not require a release cycle every time something changes.

shopping_cart

Digital Engagement

The customer facing layer, including shopping cart, order management, and self service portals.

fact_check

Revenue Assurance & Reconciliation

Matching billed usage against actual usage, so revenue does not quietly leak away across edge nodes.

Engineering Stack

How We Build It

Everything is built on Java and Spring Boot, structured as independent microservices instead of one large application, and deployed on Kubernetes so individual components can be updated, scaled, or replaced without touching the rest of the system.

If you already have a platform in place, we can modernize it step by step instead of forcing a full replacement.

Deliverable Outcome: What You Get

True Commercial Agility & Comprehensive Knowledge

A billing and OSS environment where launching a new plan is a configuration change, not a development project. A system that is documented and understood by whoever maintains it next, not just the people who originally built it.

Southeast Asia

Billing Modernization for a Tier 1 Telecom Operator

The operator's billing platform was a single, monolithic application running on manually managed servers. Adding a new pricing plan required a full regression test cycle and a scheduled release window, often a lengthy process. The system also lacked real-time charging flexibility, which limited the operator's ability to launch more competitive prepaid offers.

Result: Improved reliability during peak operations and faster product and pricing change cycles across the billing environment.
Latin America

Product Catalog and Digital Engagement Platform for an MVNO

The operator managed pricing plans and bundles through manual configuration and spreadsheets, with no self-service ordering experience for customers. Every offer change required backend engineering effort.

Result: Faster launch of new plans and offers, alongside improved self-service adoption.
