I recently bought a web platform that uses Google Maps API, however the maximum quota set by Google is not enough for my need.
My account already has a credit card for billing. I have not found any option that I can modify this fast.
In Google developer there is only form, but so far no one answered me.

You can setup your billing for Google Maps via this page. You will also want to make sure that your app is using the Maps API key for your account.
