Foley Mansfield Cuts Billing Deductions and Hits 600% ROI with AI-Powered Pre-Bill Review

As a national defense litigation firm with 13 offices, Foley Mansfield faced millions of dollars in annual billing deductions across 55,000 line items flagged by insurance-carrier clients for Outside Counsel Guideline (OCG) non-compliance. Billing attorneys spent over 2 hours per month manually reviewing pre-bills against hundreds of client-specific OCG rules in PDF or Excel files, yet non-compliant items still slipped through, and only 25% of deducted amounts were ever recovered via appeals.

The firm deployed Hercules AI's data-verification platform to automate pre-bill review, processing hundreds of client OCGs to extract and enforce billing rules and flag potentially non-compliant entries before bills went out. End-to-end deployment took under two months, and after a pilot spanning two billing cycles the tool was rolled out firmwide, with 100% of billing attorneys onboarded.

Pre-bill review became roughly twice as fast, with some partners finishing in 15-30 minutes instead of 2+ hours, and the system now detects 41% of potential non-compliant entries ahead of time. The firm realized a 600% ROI within the first year, driven by fewer deductions and a faster WIP-to-cash cycle.

• Automating OCG rule extraction and pre-bill checks let billing attorneys catch compliance issues proactively instead of fighting write-offs via appeals after the fact.
• Fast, low-IT-burden deployment (under 2 months) and self-serve training (a 7-minute video) drove 100% firmwide adoption.
• Early results in pre-bill review justified expanding the same platform upstream to AI-powered time capture.
