Add credits
Pick $10, $25, $50, $100 or type your own amount, then choose Add credits. Each amount is between $10 and $100,000. You are sent to a hosted checkout page to pay by card, and your balance updates a few seconds after payment. Purchased credits are valid for 12 months from the date of purchase (section 6 of the Terms of Service).
Organization wallet
If you administer an organization you also see its wallet: credits added, Used this period across all teams, and the Org available balance. Under Per-team allocation you can set each team's cap. A team spends at most its allocation; the organization spends at most its wallet.
