What to look for in wholesale VoIP billing software

Selecting a wholesale VoIP billing platform requires a clear understanding of the technical and operational demands of carrier-grade networks. The following five features are essential for every wholesale operator:

Real-time CDR rating

Wholesale VoIP generates millions of call detail records per second. Your billing system must rate these in real time, not batch process them hours later. Real-time rating prevents credit overruns, enables dynamic pricing, and ensures accurate settlement with interconnect partners. Platforms like JeraSoft process 1M+ CDRs/second; platforms like ASTPP require custom optimisation to achieve this.

Dynamic least-cost routing (LCR)

Margin in wholesale VoIP is made or lost on routing decisions. Your billing system must integrate with your routing engine to apply the cheapest available route per call, then rate it correctly. This requires tight coupling between the switch and the billing platform. JeraSoft and PortaOne both handle this natively; ASTPP requires custom integration.

Interconnect settlement

Wholesale operators manage agreements with multiple carriers, each with different rates, settlement terms, and currencies. Your billing system must track these relationships, apply per-partner rates, and generate settlement reports for accounting. This is where carrier-grade platforms like JeraSoft excel and where SaaS platforms like Telgoo5 struggle.

Fraud detection

A single weekend of SIM-box fraud or traffic pumping can cost more than an annual software license. Modern wholesale billing platforms must include anomaly detection for unusual traffic patterns, spike alerts, and integration with fraud management tools like AlarisLabs. This is non-negotiable for operators handling international traffic.

Scalability and uptime SLAs

Wholesale carriers cannot afford downtime. Your billing system must scale horizontally to handle traffic spikes without degradation and include professional support with guaranteed response times. Open-source solutions like ASTPP offer no SLA; commercial platforms like JeraSoft include 24/7 support with defined uptime guarantees (typically 99.9%).

Wholesale vs retail VoIP billing – key differences

Wholesale and retail VoIP billing serve different business models and require different technical approaches:

Wholesale operators require platforms built for complexity and scale. Retail operators can use simpler, SaaS-based solutions. Choosing a retail platform for wholesale use is a common mistake that leads to billing errors and lost revenue.
