Yes, build credits act as your “currency” in TeamCity Cloud. You can exchange build credits for additional storage, data transfer, concurrent build capacity on self-hosted build agents, build minutes, monthly prepaid build agents, or additional committer slots.
When you purchase additional build resources, these credits will be deducted from your balance every month. You can stop these recurring deductions at any time. Any build resources you have already redeemed will remain available until the end of the current month.
Build credits from your subscription expire and are replenished at the end of each month. Build credits purchased on-demand do not expire and carry over month to month.
