INVOICE PROCESSING
Stripe Recurring-Charge Drift Watcher
Every time a vendor's Stripe invoice is finalized, compare the charged amount against the contracted recurring rate stored in Airtable and post a Slack alert when it drifts…

What it does
Watches incoming Stripe invoices and catches the moment a recurring charge no longer matches what you agreed to pay. It pulls the contracted monthly rate from your Airtable vendor register, computes the variance, and only escalates when the difference exceeds your allowed threshold (absolute dollars or percent). Silent passes stay silent; real drift hits a Slack channel with the numbers attached.
When to use it
Use it when you pay vendors on Stripe-billed subscriptions and want to catch sneaky price increases, proration surprises, or duplicate line items before finance approves payment. Ideal for finance ops teams managing dozens of SaaS or service contracts where nobody is eyeballing every invoice.
How it works
- 1Stripe fires when an invoice is finalized for a subscription.
- 2The flow looks up that vendor's contracted recurring amount and tolerance in Airtable.
- 3A logic step computes the variance between charged and contracted amounts.
- 4If the variance is within tolerance, the run ends quietly.
- 5If it exceeds tolerance, a Slack message posts the vendor, expected vs. actual amount, and the invoice link for review.

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.
