If you exceed your monthly spending limit you will be notified about the increase via a mail and through a banner in admin as well.

Our customer support team will reach out via mail if you exceed monthly spending limits for two consecutive months. You will be requested to upgrade your billing to a higher plan. In the absence of plan upgradation, if you exceed the spending limit for the third consecutive month you may face blockage and will be unable to use some important features.
