Nanonets Agents · Accounts Payable

Catch duplicate invoices before they pay

The agent fingerprints every invoice and fuzzy-matches against history — exact copies, near-duplicates, and resubmissions across email, portal, and EDI. Suspects are blocked before payment runs.

How it works

From inbound invoice to duplicate verdict.

1
Every invoice gets fingerprinted

Vendor, PO, amount, date, line items, and remit-to are hashed and indexed the moment an invoice lands — from any channel.

2
Agent fuzzy-matches in real time

Exact matches, near matches (same vendor + amount within N days), resubmissions across channels, and credit-memo offsets. PO numbers with different prefixes still link up.

3
Suspects route for review

High-confidence duplicates are blocked from payment. Borderline cases route to AP with both invoices side-by-side and the matched fields highlighted.

Use cases

Wherever duplicate pay is a risk.

Cross-channel AP

Vendors send the same invoice by email and portal — the agent links both before either pays.

Resubmission catch

A vendor follows up with INV-001 and INV-001-R. The agent spots the rename and flags it.

Credit-memo reconciliation

Match credit memos to the original invoice automatically — no manual lookup, no double-pay.

Recovery audit

Backscan years of payments for duplicates you already paid — recover real cash without a contingency firm.

M&A AP cleanup

After an acquisition, dedupe AP across two ERPs before consolidating ledgers.

High-volume shared services

When thousands of invoices a day flow in, the agent does the matching humans can't keep up with.

FAQ

Frequently asked questions

It fuzzy-matches on vendor name, normalized PO numbers, amount, date proximity, and line-item fingerprints. The same invoice with a trailing '-R' or rounded amount still links up.
