Summary

Manual QA processes leave room for error, especially at scale. For this tolling system integrator, manually reviewing invoices or conducting spot checks led to missed mistakes and avoidable customer disputes. The result?

Frustration, rework, and operational inefficiencies.

With CSG’s intelligent quality assurance solution, the provider now reviews 100% of outgoing invoices in real time, automatically identifying errors before they reach customers. In just six months, the provider increased accuracy, streamlined workflows and gave its teams more time to focus on high-value tasks.

The Customer

A leading tolling system integrator serving multiple U.S. regions, known for implementing large-scale intelligent transportation systems and prioritizing operational excellence.

The Challenge

QA was primarily manual, time-consuming, and based on small sample sizes. This resulted in too many errors slipping through, leading to customer confusion, increased service calls, and costly rework.

  • Invoice errors were often caught after they reached customers
  • QA sampling didn’t scale, missing key discrepancies
  • Teams spend too much time on routine reviews, not enough on strategic issues

The provider needed a way to scale QA without scaling staff and prevent issues from impacting the customer experience.

The Solution

The provider implemented an automated QA solution that audits 100% of outgoing invoices in real time:

  • Every invoice is checked against business rules and authoritative data
  • Discrepancies are flagged for review before they go to customers
  • A dashboard gives teams visibility into patterns and issues

With this proactive approach, the provider significantly reduced manual workload, boosted accuracy and built stronger customer trust.
