Plus starts with a 14-day free trial, once per company. You add a card, but you aren't charged until the trial ends; cancel before then and you pay nothing.
Go to Settings, then Plan & billing, to see your plan, what you've used this month, and when it renews. Click Manage billing to change plans or seats, update your card, see invoices, or cancel.
If a payment fails, we retry the card for a while and show a note in Plan & billing. Your plan keeps working in the meantime.
