Integrations & Automations Activity

We are having trouble understanding our Integration & Automation activity.
we are currently using above our account limit and are trying to understand how and where they are used. Also the implications of turning then off?
Having had a look at the activity on our master board the integration is a copy of the automation activity is this correct.

Does anyone have some information to help me understand this, also is it possible to buy a top up or one off boost to the quantities rather than jumping up to the next plan as lot of the usage was an error on our part but we will never catch up and reset the balance.
