What happens if my Repository exceeds the 10GB limit?

Hello GitLab community,

I’m new to GitLab.com and I am looking to recommend it to my current team to use in future projects.
The majority projects here have a size range from 2 to 7GB so GitLab.com will serve us well.

But my doubt is that IF one of my projects ends by exceeding the 10GB storage limit, what happens? Could I purchase more limit? Is the last commit reverted? Is the ability to commit revoked?

Thanks in advance for any answer!
Have a nice day.

Regards,
PEREIRA, Alan
