When you run out of builds

Extra builds are for months when you ship a lot.

• Buy a pack in Billing. It's a one-time payment.
• Extra builds are used only after your plan's monthly builds run out.
• They never expire while your account is open.
• You need an active plan to buy them.
• A cancelled build that used an extra build gives it back.

Unused extra builds can be refunded within 14 days of buying them. See Refunds.
