Explain it simply
A company linked its payment, accounting, spending, sales, support and email apps to one AI chat. Now the founder can ask questions that span all of them, like checking a welcome email series for problems. In one audit the AI noticed a discount code had stopped going out, and the team fixed it.
What was done
He connected 22 company data sources to Claude in one chat, including Stripe, QuickBooks, Ramp, HubSpot, Help Scout and Klaviyo.
Most tools used Claude's built-in connectors; for the others he set up custom MCP connectors.
He asks it for audits (the email welcome series, the affiliate program), daily reports with actions, and cross-checks between Google Analytics and Metabase on why sales are down for a specific deal.
How it went
The welcome-series audit found that a discount code had stopped sending. He says "that error cost us $60,000" and that the team fixed it.
- A short self-reported post. It doesn't say how the $60,000 was worked out or how long the connector setup took.
- The AI found the problem; people fixed it. Nothing in the post says Claude changes anything in the connected apps.
Prompt
You have read-only access to [list of connected apps].
Audit our [email welcome series / affiliate program / checkout flow]:
1. List each step customers should receive, with what it should contain (offer, discount code, link).
2. Check the last [30] days of data in [email tool] and [payments tool] for steps that stopped sending, codes that weren't redeemed, or numbers that dropped sharply.
3. For each problem: what you found, the data behind it, an estimate of the impact with the math shown, and who should fix it.
Don't change anything in any app. If data is missing, say so instead of guessing.Setup notes
- Start with the apps that already have built-in connectors, and grant read-only access where the app allows it.
- Ask for one audit at a time and check the first findings against the app's own reports before acting.
