INVOICE PROCESSING
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.
How it runs
The automated pipeline, trigger to output.
- TriggerNew pending payout created in StripeStripe
- ActionQuery paid-invoice history in PostgresPostgres
- LogicMatch on vendor + amount + invoice number
- ActionCancel the Stripe payout if duplicateStripe
- OutputAlert AP team in Slack with both recordsSlack
What it does
Intercepts every outgoing vendor payment in Stripe and compares it against your ledger of previously paid invoices before the money leaves your account. If it finds a match on vendor, amount, and invoice number, it cancels the pending payout and alerts your finance team instead of paying twice.
When to use it
Use this when AP processes high invoice volume and the same bill occasionally arrives through multiple channels (email, portal, paper) and gets entered twice. It is the safety net for the moment right before funds move.
How it works
- 1A pending payout is created in Stripe, firing the trigger.
- 2The flow pulls the invoice metadata (vendor ID, amount, invoice number, date).
- 3It queries the Postgres paid-history table for a matching record.
- 4A logic branch decides: clean invoice continues, suspected duplicate is flagged.
- 5On a match, the Stripe payout is canceled so no money sends.
- 6A Slack alert posts to the AP channel with both invoice records side by side for a human to resolve.
