INVOICE PROCESSING
Flag Missing Expected Vendor Invoices Before the Payment Run
Each day, checks recurring vendors against their expected billing cadence and alerts AP in Slack when an invoice that should have arrived is missing.
How it runs

- OutputPost grouped missing-invoice alert to AP Slack channelSlack
What it does
Watches your roster of recurring vendors (rent, SaaS, utilities, retainers) and detects when an expected invoice has not arrived within its normal billing window. It posts a clear Slack alert to the AP channel listing each overdue-to-arrive vendor, the expected amount, and how many days past the usual date it is — so nothing silently slips through the payment run.
When to use it
Use it when you pay the same vendors on a predictable cadence (monthly, quarterly) and a missing invoice means either a billing error, a lost email, or a service lapse you need to catch early. Best for AP teams running scheduled payment batches.
How it works
- 1A daily schedule fires the workflow each morning.
- 2Query Postgres for active recurring vendors and their expected next-invoice date and amount.
- 3Cross-check received invoices against each vendor's cadence window.
- 4Branch: keep only vendors whose expected invoice is past due and not yet received.
- 5Post a grouped alert to the AP Slack channel with vendor, expected amount, and days overdue.

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.
