What an invoice actually costs to process.

The numbers behind our ROI calculator come from published 2026 benchmarks. Here's the short version — and the full sourced report.

$12 – $22 / invoice
Paper (fully manual)

Keyed by hand, sorted, archived, routed.

$3 – $5 / invoice
Emailed PDF (OCR / manual review)

Still an unstructured image — staff verify and correct.

$0.50 – $1.35 / invoice
Structured e-invoice (EDI / automated)

Flows into the host; staff handle exceptions only.

The lever is the format jump: move a supplier from paper/PDF to a structured feed and each invoice drops toward ~$1 to process. PunchProxy is the on-ramp that makes that jump for suppliers who can only send a flat file or EDI 810 — it is not OCR or a full AP suite.
