Any user (including those with non-administrative privileges for organizational accounts) can check the balance and storage quota associated with the present account, to verify, for example, that their respective levels of consumption are not approaching their total limiting amounts. We explain how to do so in this page.
Once the account is left with low levels of remaining available balance, the actions associated with increasing the Account's balance should be performed by the Owner or an Administrator of the account following these instructions.
Similarly, the moment the account is running low on available free storage space, a storage quota top-up should be considered by the Owner or an Administrator of the account, as explained here.
An explanation on how to add or change information about the alternative methods for performing future payments can be retrieved in this page.
