Invoice Processing Cost Statistics
Last updated: June 2026 · 6 sourced statistics
Few back-office metrics are benchmarked as thoroughly as invoice processing cost. The spread is dramatic: an average organization pays $12.88 per invoice while best-in-class automated teams pay a fraction of that — a gap that compounds across thousands of invoices a year. All figures below trace to Ardent Partners and Billentis.
Key takeaways
- $12.88 — average all-in cost to process one invoice (Ardent Partners, 2025).
- Best-in-class teams pay 79% less and process 5x faster.
- E-invoicing reduces processing costs 60–80% versus paper (Billentis).

Exception invoices — roughly a quarter of volume — cost a multiple of clean invoices to resolve and account for a disproportionate share of total AP cost (Ardent Partners).

At 1,000 invoices a month, the gap between average ($12.88) and best-in-class (~$3) processing is roughly $120,000 a year (derived from Ardent Partners figures).

Frequently asked questions
Why does invoice processing cost so much?
Labor dominates: manual data entry from PDFs, exception chasing, approval follow-ups, and payment prep. Exceptions — about a quarter of invoices — consume a disproportionate share.
What do best-in-class teams pay per invoice?
Roughly $2–3, about 79% below the $12.88 average, achieved through e-invoicing, automated capture, and high straight-through processing rates (Ardent Partners).
How do I cut my per-invoice cost?
Push suppliers to structured e-invoicing, automate capture and matching, fix master-data issues that cause exceptions, and set approval thresholds that auto-route routine invoices.
