Ensure you stop builds if you don’t want to be billed.
Then, you should definitely look in to the reason why 2 builds are being triggered when you commit – there’s an error in your workflow. I’d suspect something like duplicate hooks.
Absolutely! Feel free to upgrade any time. Usually, if you haven’t yet been billed for extra build minutes, our system will acknowledge this on-the-fly. However, if there’s any issues with billing on the Pro plan, you can raise a ticket and we can take care of things!
