INVOICE PROCESSING
Invoice Duplicate and Anomaly Screen Before Matching
Screens every new invoice for duplicates, mismatched vendor banking details, and out-of-pattern amounts before it enters the three-way match.
How it runs
The automated pipeline, trigger to output.
- TriggerNew invoice row inserted in PostgresPostgres
- ActionPull payment history and vendor masterPostgres
- LogicAgent screens for duplicates and anomalies
- ActionRelease clean invoices to match queuePostgres
- OutputOpen Linear review task for suspect invoicesLinear
What it does
Adds a fraud-and-duplicate gate ahead of matching. An agent reviews each new invoice against payment history and vendor master data, looking for repeat invoice numbers, changed bank accounts, round-number anomalies, and vendors not on file, then explains anything it flags.
When to use it
When you want a safeguard against duplicate payments and invoice fraud before invoices flow into the automated match-and-pay pipeline, without a human screening every one by hand.
How it works
- 1A new invoice row in Postgres fires the trigger.
- 2The agent pulls recent payments and the vendor master record for context.
- 3It reasons over duplicate invoice numbers, altered banking details, amount anomalies, and unknown vendors.
- 4A logic step splits clean invoices from suspect ones.
- 5Clean invoices are released into the matching queue in Postgres.
- 6Suspect invoices are placed on hold and a Linear task is created with the agent's reasoning and the specific risk signals for an AP analyst to review.

More Invoice Processing workflows
Catch duplicate invoices as they hit your AP inbox
Watches your accounts-payable Gmail inbox for incoming invoice emails, fingerprints each one, and routes likely duplicates to a review label instead of into the approval queue.
Gate invoice approvals on a duplicate cross-check
When an approver clicks Approve in your AP system, a webhook re-validates the invoice against paid history in Postgres and Stripe charges.
Nightly audit that flags duplicate payments already made
Runs every night to scan the last 90 days of Stripe payments against your Postgres invoice ledger.
Block duplicate Stripe payouts before they send
When a new vendor invoice is queued for payment in Stripe, cross-check it against your paid-invoice history in Postgres and halt any payout that matches an already-paid invoice.
Agent that codes Front invoices to GL accounts and drafts a bill
An agent reads each Front vendor invoice, assigns GL account codes per line item using your chart of accounts and past coding history.
Detect duplicate Front invoices and archive originals to S3
Parses each Front vendor invoice, checks it against a history table for duplicates, archives the source PDF to S3 with a normalized key, and alerts AP when a duplicate is caught.
