This looks like the right Stripe foundation. Since you already mention dunning, I’d bake in a few retention details early so you don’t have to retrofit them later:

• treat invoice.payment_failed as a recoverable state, not an immediate downgrade
• keep a grace-period timestamp on the subscription
• use Stripe Customer Portal links in emails / UI so updating the card is one click
• listen for invoice.paid to auto-recover accounts
• record cancellation reasons somewhere lightweight so you can see why MRR is shrinking
• keep voluntary cancellation metrics separate from failed-payment churn

That combination usually gives much better visibility into where revenue is leaking.

If building the recovery emails in-house isn’t a priority, SaveMyChurn (https://savemychurn.com) is a nice fit here — it’s an automated churn-recovery tool for Stripe with AI-personalized emails for failed payments and at-risk subscribers.
