INVOICE PROCESSING
Detect recurring vendors that missed their expected invoice cadence
Runs daily, checks each recurring vendor's expected billing date in BigQuery, and alerts when a vendor that should have invoiced by now hasn't.
How it runs
The automated pipeline, trigger to output.
- TriggerDaily cadence check schedule
- ActionQuery expected vendor invoice datesBigQuery
- LogicFilter vendors past expected date
- ActionEstimate accrual from trailing averageBigQuery
- OutputPost overdue-vendor digestSlack
What it does
Inverts the usual anomaly check: instead of catching a charge that is too high, it catches the absence of an expected charge. Every day it compares each recurring vendor's expected next-invoice date against what has actually arrived, and surfaces vendors that are overdue to bill.
When to use it
Use this when a missing invoice creates real risk: a service that auto-suspends on non-payment, a vendor that batches several months into one shock bill, or an accrual you need to book on time. It keeps your AP calendar honest.
How it works
- 1A daily schedule starts the run each morning.
- 2The flow queries BigQuery for every active recurring vendor and its expected invoice date and typical cadence.
- 3A branch isolates vendors whose expected date has passed with no matching invoice recorded.
- 4For each overdue vendor it estimates the likely accrual amount from the trailing average.
- 5A consolidated digest of overdue vendors and estimated accruals is posted to the AP Slack channel for follow-up.

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.
