How a balance behaves at zero — what makes an included allowance a hard cap, what lets usage go past it, and what billing controls actually do. Load when the request mentions a cap, limit, overage, or credit allowance, or the customer already has billing controls set.
Steps for updating a customer's billing state — attaching a plan, updating a subscription, or scheduling a change. Use whenever the user asks to change what a customer is billed for.
Understanding an unusual billing setup before acting on it — when a trial starts or ends billing, how entity- and seat-scoped subscriptions differ from the customer's own, what a customize diff actually changes, and how caps, overage, and top-ups behave. Load when a customer's state does not match the plain reading of their plan.

free_trial on attach: { duration_length, duration_type (day|month|year), card_required, on_end }. Always pass duration_type.If the customer the customer is NOT on a paid plan (free plan or no plan at all). 2 options:
free_trial and set card_required false. The subscription starts with no card and ends at trial end if none is added. While on it, the customer cannot upgrade or attach another plan until they add a card via the Stripe billing portal.free_trial and card_required: true and long_lived_checkout If the customer has no payment method, the attach returns a checkout URL to collect a card; they are charged when the trial ends. This should be done with a long-lived checkout URL param.The customer already has an active (Stripe) subscription — common in sales-led trials.
on_end: "revert" . This grants the plan in Autumn without touching the Stripe subscription; at trial end Autumn moves the customer back to their original plan, preserving the existing billing cycle.Updating or ending a trial
free_trial. The duration is counted from now, not from the original start. A 14-day extension on day 10 of a 14-day trial gives 14 more days, not 4.free_trial: null to end the trial immediately instead.
