Allow me to chime in and fill you up about Google Workspace verification transaction.
Google do this so they can ensure that your money will be sent to the right bank account when it is actually sent. You'll want to contact Google support to verify if google will take the money back. If so, you can just leave the transaction uncategorized until your first payment. If not, then we can record it as expense transaction. Although, I'd still suggest working with your accountant to help you choose which transaction category you should use.
