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.
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
