PRGX, SC&H & Recovery Audits: Mid-Market Guide
The established providers of AP recovery audits — PRGX, SC&H Group, Strategic Audit Solutions, apexanalytix, and Illumis Global — are credible, experienced firms. PRGX recovers $1.8 billion annually. SC&H has 30 years of contract compliance audit experience. apexanalytix uses AI-powered detection at scale.

How Recovery Audit Economics Work

Contingency fees of 20 to 35 percent of recovered funds. PRGX benchmarks: approximately $1 million per $1 billion in supplier spend. For Fortune 500 at $5 billion spend: $5 million potential recovery. Economics work excellently. For mid-market at $30 million spend: approximately $30,000 potential recovery. Firm retains $6,000 to $10,000. The engagement barely justifies itself for either party. This is arithmetic, not criticism. The model was built for enterprise spend pools.

Three Structural Limitations for Mid-Market

Periodicity. Annual or biannual cycles. Between audits, drift accumulates. Recovery rates deteriorate with time: 91 percent at 90 days, 31 percent at 24 months. The periodic model guarantees a portion of leakage ages beyond recovery. Transactional focus. Standard audits find duplicates, missed credits, wrong amounts. They do not find systematic contract-level drift — rate variance patterns, recurring scope expansion, SLA credits earned quarterly and never claimed. That requires contract-level analysis standard methodologies were not built for. Retrospective orientation. Audits recover from the past. They do not change the process generating the leakage. Twelve months after the audit, drift rebuilds to the same level because the same contracts are still not compared to the same invoices.

Continuous Enforcement as Alternative

Subscription pricing at $2,500 to $4,000 per month. Every invoice validated against contract terms before payment. No 12-month gaps. Contract-level validation catches systematic drift patterns. Recovery audit at mid-market might find $100,000 in past overpayments and recover $65,000 after fees. Continuous enforcement prevents $200,000 to $400,000 annually for $36,000 per year. The math favors prevention at mid-market scale.

When to Use Each or Both

A manufacturer with significant accumulated past overpayments may benefit from targeted recovery for those specific vendors. Going forward, continuous enforcement prevents recurrence. The margin drift diagnostic is the starting point: it identifies both what is recoverable from the past and what should be enforced going forward.

Questions & Answers

What is PRGX?

Largest global AP recovery audit firm. $1.8B+ annual recoveries. 300+ leakage points identified. Primarily Fortune 500 with billion-dollar spend.

Are recovery audits right for mid-market?

Contingency economics work best above $500M spend. At $30M: ~$30K potential recovery. Continuous enforcement at $30K-$48K/year prevents $150K-$450K — better mid-market economics.

Recovery audit vs continuous enforcement?

Recovery: backward, periodic, transactional errors. Enforcement: forward, continuous, contract compliance. At mid-market scale, enforcement prevents 5-10x more annually.

Can I use both?

Yes. Diagnostic identifies past overpayments (recoverable) and ongoing drift (preventable). Pursue recovery for accumulated amounts. Deploy enforcement for permanent prevention.

What are the best AP recovery audit firms?

PRGX, SC&H Group, Strategic Audit Solutions, apexanalytix, Illumis Global. All credible with decades of experience. Best suited for enterprise scale. Mid-market needs right-sized enforcement approach.
