How a global insurer cut legal costs by ~18% using AI-augmented invoice review

Client: Global insurer
Annual Legal Spend: $140M

Challenge:

Processing 6,000+ invoices monthly while relying on a manual process was lengthy, delayed payment turnaround times and resulted in inconsistent review and overspend.

Solution:

Expert partnership of 5+ years with Morae Global, deploying AI-powered spend analysis technology with human expert oversight, in one managed solution.

Results:

• 8.5% achieved initially with a further 10 – 12 % driven by the addition of qualitative review bringing the total savings to ~18%. Savings projected to be up to $28M in the next 12 months.
• 14,000 internal hours saved annually (≈7 FTEs redeployed to strategic work).
• Real-time visibility into law firm performance enabling strategic panel management.

The insurer was struggling with high legal costs and inevitable cost pressures from the business. Their reliance on manual review for over 6,000 invoices monthly was leading to costly errors and minimal insight into spend trends or potential efficiencies.

Key pain points:

• Costs: Pressure to both drive down expenditure and get more value from law firms
• No scalability: A manual process combined with the pressure to do more with less pointed to a need for a wholescale change of process
• Inconsistent compliance: Billing guideline violations routinely went undetected; no systematic enforcement
• Limited intelligence: Lack of detailed, collective analysis e.g. which firms delivered value, benchmark rates against standards, or quantify savings opportunities

Human-enhanced AI

The insurer partnered with Morae to deploy a managed solution that combines automated analysis with expert human review.

AI handles quantitative review:

• Automated invoice ingestion and extraction of relevant data
• Rate cap enforcement, prohibited expense detection, mathematical accuracy verification
• Processes thousands of line items in minutes with 99%+ accuracy to spot clear-cut violations

Humans handle qualitative analysis where needed:

• Block billing appropriateness (efficiency vs. obfuscation?)
• Excessive time assessment (justified by complexity or inefficient?)
• Staffing leverage optimisation (senior lawyer time warranted or wasteful?)
• Billing narrative quality and completeness

This division addresses a central challenge in AI deployment: false positives damage law firm relationships whilst false negatives miss genuine problems. The hybrid approach achieves optimal accuracy—substantially higher than pure automation.

Rather than providing software for the insurer to operate, Morae’s Spend Intelligence solution spans: invoice ingestion, AI analysis, human quality control, dispute management, and reporting. The insurer receives insights, not tools—eliminating the need to build internal expertise in AI deployment or legal spend analytics.

The solution was configured to the insurer’s specific billing guidelines, organisational structure, and matter taxonomy without expensive bespoke development—providing tailored fit whilst maintaining supportability.

Critical success factors included:

• Phased rollout building confidence before full deployment
• Collaborative law firm engagement rather than adversarial approach
• Continuous optimisation over decade-long partnership
• Executive sponsorship from both General Counsel and CFO

Financial

• Initial 8.5% savings ($12M cumulative over three years) came primarily from recovering quantitative violations: rate caps, prohibited expenses, mathematical errors, duplicate charges.
• Current ~18 - 20% target (targeting $28M annually) reflects enhanced capabilities as generative AI enables deeper qualitative analysis: block billing patterns, excessive time across matters, staffing leverage issues, and predictive analytics flagging high-risk matters before costs escalate.

Note: Total programme costs including subscription fees and success-based pricing have not been disclosed. Complete ROI analysis requires visibility to full cost structure.

Operational

• 14,000 internal hours saved annually freed approximately 7 FTE equivalents.
• Data-driven law firm management replaced intuition-based decisions:
  - Objective performance rankings identifying which firms consistently deliver value
  - Rate positioning analysis revealing firms materially above or below market
  - Trend analysis identifying performance degradation early
  - Practice area insights showing where panel restructuring would have highest impact
• Executive reporting transformed legal into a sophisticated cost centre managing spend strategically rather than processing invoices reactively. Real-time dashboards provide CFO with granular visibility, quantified savings attribution, and forecasting supporting budget discussions.

Key Takeaways

• The 8.5% → 18% trajectory demonstrates that Spend Intelligence delivers immediate value (quick wins from obvious violations), sustained savings (multi-year results from systematic enforcement), and increasing returns (as AI capabilities improve). This illustrates the benefits of viewing spend management as continuous discipline rather than one-time optimisation.
• Insurance industry success shows that even highly complex litigation and claims matters can be systematically analysed. High invoice volumes, multiple jurisdictions, and diverse practice areas all become manageable with appropriate methodology.
• Operational transformation from transactional processing to strategic management may be as valuable as direct cost savings. The 14,000 hours saved enabled fundamental maturity evolution in legal operations.
