The downside with using the cancelling/resuming instead of pausing is that it can create reporting issues, especially for MRR based companies.

Churnkey has a good guide on how they use pauses: https://docs.churnkey.co/billing-providers/stripe

Churnkey uses Stripe's built-in pause feature which will update the subscription's pause_collection[behavior] to mark_uncollectible. The resumes_at field will automatically be set by Churnkey depending on the length of the pause selected.

You can specify the maximum pause length allowed by customers while configuring your offboarding flow.
