If these deposits are being processed through Quickbooks Payments then yes, that is the service fee for processing the deposit. https://quickbooks.intuit.com/payments/pricing/ goes over how much Intuit charges for the deposits. If you are using a different third party to process payments then that may be charging a service fee. It's important to pick this fee up as an expense so that your sales are accurately recorded. For example, if 10$ is withheld from the deposit then a journal entry should be made that credits sales for the amount and debits Service Charges or an equivalent expense account. Hope this helps!
