Outcome
Paid clients move into onboarding in minutes not days, with sales, finance, and delivery seeing the same handoff state and no duplicate kickoffs.
High Automation system
Payment-to-Onboarding Flow
A flow that turns a confirmed Stripe payment into kickoff: it updates the CRM stage, notifies the team, and fires the onboarding intake the moment money clears, without double-firing on Stripe's retries.

System facts
Payment-to-Onboarding Flow uses an event-driven automation layer for AI Automation.

The architecture connects listen for the verified, stripe, make, and completed workflow with an explicit control path.
Main risk
Stripe delivers the same event more than once (at-least-once delivery with retries), causing duplicate onboarding emails, tasks, or charges-side actions.
Prevention
Treat event.id as an idempotency key recorded in the same step as the action, and react to the fulfillment event rather than client-side success.
Fallback
Hold ambiguous or failed payment events in a payment-review stage and alert an owner to confirm before onboarding proceeds.

How it is built
A flow that turns a confirmed Stripe payment into kickoff: it updates the CRM stage, notifies the team, and fires the onboarding intake the moment money clears, without double-firing on Stripe's retries.
- 01Listen for the verified Stripe event (checkout.session.completed for Checkout, or payment_intent.succeeded) through the validated webhook layer
- 02Dedupe on Stripe event.id so retried deliveries do not double-onboard, recording the processed id alongside the action
- 03Update the CRM stage to paid/won, attach amount and product, and notify sales plus delivery on Slack or email
- 04Trigger the onboarding intake (welcome email, intake form, kickoff task) and tag the contact as onboarding-started
