INVOICE PROCESSING
Audit Stripe Recurring Invoices for Line-Item Drift Before Charge
When Stripe finalizes a recurring invoice, this compares every line item and quantity against the customer's prior-period invoice and pauses the charge for review if anything…
How it runs
The automated pipeline, trigger to output.
- TriggerStripe invoice.finalized eventStripe
- ActionFetch customer's prior-period invoiceStripe
- LogicDiff line items, prices, and quantities
- LogicBranch: any delta over threshold?
- ActionPause invoice auto-advance to hold the chargeStripe
- OutputPost side-by-side diff to billing Slack channelSlack
What it does
It intercepts each newly finalized Stripe subscription invoice, pulls the same customer's previous invoice from history, and diffs them line by line. If a line item appears, disappears, changes price, or shifts quantity beyond a set tolerance, the invoice is flagged and held instead of auto-charged.
When to use it
Use this when usage-based or seat-based subscriptions occasionally balloon without anyone noticing until the customer disputes the charge. It catches silent metering bugs, accidental seat spikes, and unapproved plan changes before money moves.
How it works
- 1Stripe fires `invoice.finalized` for a recurring invoice.
- 2The flow fetches the customer's immediately prior invoice from Stripe.
- 3A diff step matches line items by product and computes price and quantity deltas.
- 4A branch checks whether any delta exceeds the configured percentage threshold.
- 5If it does, the invoice's auto-advance is paused so it won't auto-charge.
- 6A Slack alert posts the side-by-side diff to the billing channel for a human decision.

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.
