The Scenario
You're the billing engineer at an API platform. Tonight at midnight, Stripe auto-generates invoices for every metered subscription. Your job — the one you've been asked to do every month and have never had a clean tool for — is to verify that the usage totals look right before the invoices go out.
Last month, one customer was billed for 40,000 API calls when their actual usage was closer to 4,000. A decimal error somewhere in the metering pipeline. The invoice went out, the customer disputed it, and the support cleanup took three days.
You open Stripe. You can look at subscription items for individual customers, but there is no consolidated view of current-period usage across all subscriptions. You'd need to navigate to each subscription, open the usage records tab, and record the total manually.
The bad version:
- Open each of the 60 active subscriptions in Stripe one at a time, record the current-period usage total and the customer email into a spreadsheet.
- Notice that three subscriptions have two subscription items each (different meters), which means more rows than expected.
- Finish at 11:45 PM — 15 minutes before the invoices generate — and realise you didn't have time to check for outliers.
Billing errors at scale destroy customer trust faster than almost any other product failure. The cleanup is always worse than the verification would have been.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It connects to Stripe and can pull current-period usage summaries for subscription items across all active subscriptions in one pass.
For each active Stripe subscription in the list on Sheet1, fetch the current period usage summary for each subscription item and write customer email, item ID, and units consumed into Sheet2
What You Get
- Sheet2 fills with one row per subscription item: customer email, subscription item ID, and current-period units consumed.
- Subscriptions with multiple items each produce multiple rows.
- The query runs against the current billing period automatically.
What If the Data Is Not Quite Ready
You want to flag usage that looks anomalously high before the invoices generate
Export usage summaries for all active Stripe subscription items into Sheet2 with subscription ID, customer email, and current period total usage — add column D that flags any row where usage exceeds 10000 units as 'review before billing'
You want to include the meter name so the team knows what's being counted
For each active Stripe subscription, fetch the current-period usage summary per subscription item — write customer email, item ID, meter name, and units consumed into Sheet2
You want to compare this month's usage against last month's for anomaly detection
Fetch current-period usage for all active Stripe subscription items and write into Sheet2 — also fetch last period's usage for the same items and write into Sheet3 — so I can compare month-over-month in a formula
The full kill chain — pull usage, flag outliers, and produce a pre-billing summary in one shot
Export current-period usage for all active Stripe subscription items into Sheet2 with customer email, item ID, meter name, and units consumed — flag any row where usage is more than 3x the previous period in column E — write a summary on Sheet3 showing total units consumed by meter name for a pre-billing review
The pattern: the anomaly detection and summarisation happen before the invoices generate, not in the aftermath of a billing dispute.
