Billing & Account
How to change your plan tier or billing interval, and what Stripe prorates automatically.
Moving between Starter, Pro, and Premium, or switching between monthly and annual billing, both work the same way from your Plan page.
On your Plan page, your current tier shows a Manage / cancel button; every other tier shows Switch to [plan]. Both open your secure Stripe billing portal, where you confirm the change. Nothing about your card details ever passes through HarperFlow itself.
Stripe prorates the difference automatically on your next invoice. Moving up mid-cycle charges you the difference for the rest of the current period; moving down credits it. You don't need to time a switch around your renewal date, and there's no separate confirmation step beyond what Stripe shows you before you finish.
Your new article quota takes effect once Stripe confirms the change, which is typically immediate. Autopilot's publishing cadence follows your quota automatically: moving from Starter to Premium, for example, moves you from a couple of articles a week toward roughly one a day, with nothing to reconfigure by hand. The premium AI writer, brand voice, autopilot, and scheduling stay on regardless of which tier you're on. See Plans and pricing for what actually differs between tiers (it's volume, not quality).
Only the account owner can start a brand-new subscription for a workspace. Once a workspace is subscribed, both owners and admins can open the billing portal to switch tiers, change the billing interval, update payment details, or cancel. See Team members and roles for the full breakdown of what each role can do.
Tip: Switching between monthly and annual billing uses the exact same "Switch to [plan]" flow as changing tiers. Pick the plan card with the interval you want before opening the portal.
