INVOICE PROCESSING
Monthly recurring-vendor cost drift report
On the first of each month, aggregates every recurring vendor's spend trend from BigQuery, ranks the biggest month-over-month movers.

What it does
Gives finance a single monthly view of how recurring-vendor spend is drifting. It rolls up each vendor's charges, computes month-over-month and trailing-quarter changes, and ranks the vendors whose costs are creeping up the fastest so budget conversations are driven by data.
When to use it
Use this for the monthly AP or FinOps review when you want one report that answers "which subscriptions are quietly growing" rather than reacting to one invoice at a time. Good for spotting slow creep that per-invoice alerts miss.
How it works
- 1A monthly schedule fires on the first business day.
- 2The flow queries BigQuery for per-vendor recurring spend across the trailing periods.
- 3It computes month-over-month and quarter-over-quarter deltas and ranks the top movers.
- 4The ranked drift table is written to a Notion page for the finance workspace.
- 5A summary with the top five increasing vendors is posted to the FinOps Slack channel linking the full report.

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.
