INVOICE PROCESSING
Catch duplicate Stripe payments for the same invoice
Watches new outbound Stripe payments and flags any that match an invoice already marked paid in the ledger, alerting AP before a vendor gets paid twice.
How it runs
The automated pipeline, trigger to output.
- TriggerNew outbound Stripe payment createdStripe
- ActionLook up prior paid payments in Postgres ledgerPostgres
- LogicDecide if it is a likely duplicate
- ActionRecord duplicate flag in PostgresPostgres
- OutputSend urgent duplicate alert to TeamsMicrosoft Teams
What it does
Guards against paying the same invoice twice. When a new outbound Stripe payment is created, it checks the reconciliation ledger for an existing paid payment to the same vendor for the same amount and, if it finds one, raises a duplicate-payment alert immediately.
When to use it
Use it when multiple people can issue vendor payments and accidental double-pays are a real risk. Catching a duplicate the moment it happens means you can recover funds while the transaction is still fresh.
How it works
- 1A new outbound Stripe payment event triggers the flow.
- 2The flow reads the payment's vendor, amount, and any invoice reference.
- 3It searches the Postgres ledger for a prior payment to the same vendor and amount already marked paid.
- 4A decision step splits on whether a likely duplicate exists.
- 5If a duplicate is found, it records a duplicate flag against the new payment in Postgres.
- 6It sends an urgent alert to the AP team in Microsoft Teams with both payment IDs so they can stop or claw back the second payment.

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.
