Executive summary

Service vendor spend leaks 1–3% annually in most mid-market companies — not through fraud, but through a structural gap between ERP AP controls and vendor contract terms. This report analyses evidence from 20 finance professional forum discussions and cross-references benchmarks from APQC, AFP, and ERP vendor disclosures to identify the six categories where leakage concentrates and the AP automation patterns that fail to catch it.

Key findings

1. 1–3% of service vendor spend leaks annually across all six leakage categories
2. Freight billing errors are the highest-frequency category — identified in 14 of 20 forum threads
3. ERP AP modules validate invoice-to-PO accuracy, not PO-to-contract accuracy — the gap is structural
4. Contract labour off-rate billing is the highest-value category by recoverable dollar amount
5. Businesses that cross-reference vendor contracts against AP data in periodic audits recover 60–80% of identified leakage

Who this is for

CFOs, controllers, and AP managers at $20M–$200M manufacturers, distributors, and B2B services businesses
