INVOICE PROCESSING
Dedupe AP Intake in Airtable Before Approval
Watches the Airtable AP intake table for new invoice rows, fuzzy-matches each against paid and pending records.

What it does
Every time a new invoice lands in your Airtable AP intake base, this workflow compares it against both already-paid and still-pending records using vendor name, normalized amount, and invoice number. Suspected re-submissions are tagged and moved to a hold view before any human clicks approve, keeping the duplicate out of the payment queue at the source.
When to use it
Use this when your AP team triages invoices in Airtable and approvals are manual. It catches near-duplicates (re-typed numbers, rounded amounts) that exact-match rules miss, before they ever reach a payout step.
How it works
- 1A new row created in the Airtable AP intake table fires the trigger.
- 2The flow normalizes vendor, amount, and invoice number into comparable keys.
- 3It scans existing paid and pending rows for fuzzy and exact matches.
- 4If a likely duplicate is found, the row is updated with a Duplicate flag and a link to the original.
- 5Flagged invoices are routed to a review channel; clean ones are marked Ready for approval.
