INVOICE PROCESSING
Flag Recurring Vendor Bills With Unexpected Quantity Jumps
On a schedule, this reads newly received vendor invoices from Postgres, compares quantities and totals to the same vendor's prior invoice.
How it runs
The automated pipeline, trigger to output.
- TriggerDaily schedule
- ActionQuery new invoices and prior-period match in PostgresPostgres
- LogicCompute per-line and total deltas by vendor
- LogicFilter to invoices exceeding growth threshold
- OutputEmail AP the creep review digestGmail
What it does
It scans your accounts-payable invoice table for bills entered since the last run, looks up each vendor's previous invoice for the same service, and computes period-over-period changes in quantity, unit price, and total. Anything that grew beyond tolerance is collected into a digest for the AP team.
When to use it
Use this for recurring operational spend like SaaS, utilities, logistics, or staffing where line counts should be stable month to month. It surfaces creeping overages and rate changes before they're approved for payment.
How it works
- 1A daily schedule triggers the audit.
- 2A Postgres query pulls invoices ingested since the prior run plus each vendor's previous invoice.
- 3A comparison step computes per-line and total deltas grouped by vendor.
- 4A filter keeps only invoices with growth above the configured threshold.
- 5A formatting step builds a readable per-vendor breakdown of what changed.
- 6Gmail sends the review digest to the AP distribution list.

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.
Run it inside a business
This workflow drops into a full company template. Import the org, and this is one of the playbooks its agents run.
