What it does

This workflow watches the SaaS subscriptions your company pays for through Stripe. When a new subscription invoice is finalized, it compares the per-seat or per-unit charge against the previous cycle and surfaces any unannounced increase so you catch SaaS price hikes before the charge clears.

When to use it

Use this when your tool stack bills through Stripe and vendors raise per-seat pricing at renewal without a heads-up. It is built for ops and finance teams managing dozens of recurring SaaS line items where small per-seat bumps add up fast.

How it works

  1. 1A Stripe invoice.finalized event for a subscription you pay triggers the run.
  2. 2The flow reads the current per-unit amount and seat count from the invoice.
  3. 3A Postgres lookup fetches the prior cycle's per-unit rate for that subscription.
  4. 4A logic step computes the per-seat delta and total cycle impact, filtering out flat renewals.
  5. 5The new rate is stored as the latest baseline.
  6. 6Confirmed hikes are posted to an MS Teams channel with the delta and the next renewal date for cancellation timing.
