National Insurer Recovered
$10M+ in Revenue Leakage
A national insurance firm with $850M in annual premiums deployed ACG's data intelligence platform to identify and recover systematic revenue leakage — recovering $10.4M in the first 12 months while permanently closing the process gaps that created it.

Client Context
A Revenue Problem Hidden in Plain Sight
The client is a national insurance carrier operating across 38 states with $850M in annual premiums written. The company had grown through a series of acquisitions over the preceding decade, inheriting diverse technology platforms, inconsistent billing processes, and fragmented data architectures that were never fully harmonized.
The CFO had flagged a persistent gap between premium income projections and actual collected revenue — consistently running 1.2–1.5% below model. At $850M in premiums, this represented $10–13M annually. Finance and operations attributed the variance to normal policy lapse and cancellation patterns, but the gap appeared structural rather than cyclical.
Internal audit had conducted two reviews of billing accuracy in the preceding 18 months, using sampling-based approaches that cleared individual transactions within tolerance bands. Neither review surfaced the systematic patterns that ACG ultimately identified — because sampling-based audits cannot detect structural process failures that affect all transactions in a category uniformly.

Systematic miscoding of policy exceptions resulting in incorrect premium calculations across 12,000+ accounts
$2.8M
annual impact
Billing Cycle Timing Gaps
Retroactive policy changes not reflected in billing cycles, creating persistent underbilling

Implementation
The 14-Week Recovery Program
Phase 1
Transactional Data Ingestion & Profiling
Weeks 1–4ACG's data engineering team ingested 18 months of transactional records from the client's policy administration system, billing platform, claims system, and reinsurance treaty management platform. Data quality profiling revealed significant inconsistencies across systems that had been masked by manual reconciliation processes.
14.2M transaction records ingested across 4 source systems
Data quality score of 67% at project start — significantly below the 85% threshold required for reliable analytics
3 weeks invested in data remediation before analysis could begin
Cross-system reconciliation gaps identified as the primary root cause of most leakage patterns
Phase 2
Anomaly Detection Model Development
Weeks 5–9With clean, reconciled data in place, ACG built an ensemble anomaly detection system that compared actual billing and claims outcomes against expected values derived from policy terms, treaty structures, and regulatory requirements. The model was designed to identify both point anomalies (individual transaction errors) and systematic patterns (structural process failures).
Ensemble model combining rule-based logic, statistical process control, and ML anomaly detection
7 distinct anomaly categories identified through unsupervised pattern detection
Each anomaly category validated against policy documentation and treaty terms
94% precision rate validated against manual review of 2,000-record sample
Phase 3
Revenue Recovery Workflow
Weeks 10–12For identified historical leakage, ACG designed and implemented a recovery workflow that generated correction transactions, routed them through the appropriate approval and regulatory compliance checks, and tracked recovery status. For ongoing prevention, automated detection triggers were integrated into the billing processing pipeline.
Recovery workflow generated 4,847 correction transactions in first 90 days
Compliance review integration ensured regulatory alignment in all recovery actions
Real-time leakage detection integrated into billing pipeline — new patterns caught at time of processing
$10.4M recovery documented within first 12 months of system operation
Phase 4
Process Remediation
Weeks 11–14Recovery without process correction produces only temporary improvement. ACG worked with the client's operations and IT teams to remediate the underlying process and system failures that created each leakage pattern — eliminating future recurrence rather than just identifying past losses.
Policy administration system configuration corrections deployed for 4 of 7 patterns
Billing workflow redesign addressing timing gaps and endorsement processing
Automated reconciliation processes replacing 6 manual monthly reconciliation steps
Ongoing monitoring dashboard tracking leakage KPIs with weekly executive reporting
Key Learnings
What This Engagement Taught Us
Data Quality Is a Revenue Issue
The engagement began as a revenue leakage investigation but immediately surfaced data quality as the foundational problem. Organizations that invest in data quality remediation as a standalone initiative often struggle to justify the ROI. Framing it as a prerequisite to revenue recovery made the investment case immediate and compelling.
Systematic Patterns Trump Spot Audits
The client had conducted periodic manual audits of billing accuracy. Those audits caught individual errors but missed the systematic patterns that drove the majority of leakage — because the patterns were structural, not random. Process-level pattern detection is categorically more effective than transaction-level sampling.
Recovery and Prevention Are Different Workstreams
Recovering historical leakage and preventing future leakage require different technical and organizational approaches. ACG ran them as parallel workstreams rather than sequential ones — recovering historical value while simultaneously building the prevention infrastructure.
Regulatory Complexity Requires Embedded Compliance Review
Insurance revenue recovery intersects with complex regulatory requirements across multiple states. Recovery actions needed compliance review before execution. Building compliance checkpoints into the recovery workflow — rather than treating compliance as an afterthought — was essential to avoiding regulatory risk while recovering value.
