Case study · Invoice automation

Six minutes an invoice, down to eighteen seconds.

A midsize distributor runs about 1,900 vendor invoices a month through DynamoDocs, matched against purchase orders in their P21 ERP. Every figure on this page is measured from the production database over the first four months of live volume. Nothing is a projection or a sample.

97% of invoices never needed a manual correction 6,288 of 6,485 invoices show no human edit anywhere in their history.
92% of invoices needed zero data entry Two thirds matched fully automatically; most of the rest needed only a one-click approval.

Scale & throughput

6,485 invoices processed in the first four months of production
1,900+ invoices per month at steady state, hands-off intake
459 distinct vendors no per-vendor templates or setup
2 in 3 matched with zero human touch read, matched to the PO, and cleared end to end
We went from six minutes an invoice to eighteen seconds, and that's only on the invoices that need review. Everything else posts without anyone touching it.

What the review queue actually contains

The third that doesn't auto-match is not data entry. 94% of review-queue invoices have no pricing or quantity issue at all. They're held for a simple sign-off: vendor notes on the PO, or receipts not yet posted in the ERP.

62% · Clean, one-click approval
no pricing or quantity issue; awaiting sign-off on vendor notes or receipts
14% · Arrived without a PO number
routed for a PO assignment, not a correction
21% · Genuine discrepancies caught
real price, quantity, or vendor differences held before payment
4% · Minor line questions
a flagged line detail needing a quick look

Zero-touch match rate by month

July was still mid-cycle when this was measured. Recent arrivals hadn't finished delivery reconciliation, so the month-to-date figure understates the final rate.

The queue is also where the money is protected

Over the same four months, the review queue held more than 400 genuine billing discrepancies before payment: price increases nobody agreed to, quantities that didn't match the PO, and vendor mismatches, each flagged with the evidence attached.

Methodology. Source: the deployment's production database, live records only. 1,790 test-environment records and 361 duplicates were excluded. Window: March 30 through July 28, 2026.

97% no-correction rate: 6,288 of 6,485 invoices show no human edit, status change, manual voucher, or confirmation action anywhere in their activity history.

92% zero data entry: 4,386 auto-matched invoices plus 1,584 exceptions that needed only an approval or a PO assignment, with no field changed, of 6,485 total.

Zero-touch rate: invoices ending in matched, acceptable-variance, or completed status; 4,386 of 6,485, or 67.6%.

Review-queue composition: 2,099 flagged invoices; 1,293 clean reviews, 291 without a PO number, 433 discrepancy holds, 82 line-level questions.
