Google operations admin and pricing

Question:
Does anyone know where I can find how velo manage quotas and payments to google operations?

Product:
I have connected my site monitoring (logs) to google operations via wix.

What are you trying to achieve:
I want to make sure I will not get surprise bills at the end of the month, or something.

What have you already tried:
I tried to set quotas myself, but it seem like the billing is under velo, and they or wix are the admin.
