(PM for Stripe Billing here!) If you’re an existing user of Stripe Subscriptions, you can continue as you were! Your existing integration will still work as before and your customers won’t be impacted.
That said, you’ll also get access to all of the new tools as well -- would love for you to try them (and see if it improves your experience!) If you go to the Dashboard, we walk you through what changed in detail -- let me know if that helps, or feel free to send me an email at any point: tara@stripe.com
Apologies for any confusion! No extra fees for existing Stripe Subscriptions users, even after the $1M mark. Stripe Billing is free forever at your current price.
