What it does

Watches new charges flowing through your corporate Stripe account, isolates the ones that look like recurring SaaS, and checks each merchant descriptor against your sanctioned-vendor list. Anything that does not match is fingerprinted as candidate shadow IT and routed to the employee who owns the card, with a structured review they must answer.

When to use it

Run this when finance issues virtual cards or corporate cards and you want to catch unsanctioned tools at the moment of purchase rather than during a quarterly spend review. Ideal for IT-ops teams enforcing a procurement policy without blocking cards outright.

How it works

  1. 1A new charge posts in Stripe and fires the trigger.
  2. 2A logic step filters for recurring or subscription-shaped charges and drops one-off purchases.
  3. 3The merchant descriptor is normalized and compared against the sanctioned-vendor allowlist in Postgres.
  4. 4If the vendor is unknown, an action writes a shadow-IT review record to Monday with the amount, cardholder, and first-seen date.
  5. 5A final output DMs the spend owner in Slack with the vendor name and a link to confirm or justify the subscription.
