INVOICE PROCESSING
Early Warning When Metered Stripe Usage Trends Toward an Overage
Runs mid-cycle to project each metered Stripe subscription's end-of-period charge from usage so far.

What it does
Watches usage-based subscriptions while the billing period is still open. Partway through each cycle it reads accumulated usage from Stripe, projects the full-period charge by run rate, and compares that projection to last period's actual amount. If the trajectory points to a meaningful overage, it warns the account owner before the invoice is ever cut.
When to use it
Use it for metered or usage-priced subscriptions where the bill is only known at period end. This catches a runaway API or seat-usage trend early, while there is still time to throttle, downgrade, or budget for it — instead of being surprised by the final invoice.
How it works
- 1A mid-cycle schedule triggers the run.
- 2An action reads current-period usage records and the subscription's price from Stripe.
- 3A logic step projects the end-of-period total from elapsed time and compares it to the prior period's actual charge from Postgres.
- 4Subscriptions tracking within range are skipped.
- 5For projected overages, it writes the forecast to Postgres for trend history.
- 6A Slack direct alert tells the account owner the projected charge, the percent jump, and days remaining in the cycle.

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.
