Quickbooks charge a fee when money is deposited into my bank account from invoices. can i sign up for quickbooks banking in order to save that fee?

Yes, you can sign up for QuickBooks banking to save the transaction fee, provirtually.

There are two ways to save the fee in QuickBooks. First, we can sign up for QuickBooks banking and use the Resolve | Difference option from the banking page when matching the payment to the open invoice. See the sample steps below to complete the process:

1. Click Transactions in the left panel and choose Banking.
2. Tap the correct bank.
3. Find and click the payment ($75). Choose to Find match.
   
4. Filter the transactions to Show all open invoices and customize the dates.
5. Select the invoice.
6. Enable the Resolve | Difference button.
7. Under Add resolving transactions section, choose your bank charge account as Category.
8. Enter the $25 in a negative Amount and add a Memo for your reference.
9. Hit Save.
   

Second, we can manually record the fee in QuickBooks Online by adding another line item and entering the fee in a negative amount when depositing the invoice payment:

Here's how:

1. Click + New in the left panel and choose Bank Deposit.
2. Select the bank account in the Account field and enter the Date.
3. Under the Select the payments included in this deposit section, mark the invoice payment.
4. Go to the Add funds to this deposit section, and select the bank fee account in the ACCOUNT column.
5. Enter the bank fee as a negative amount.
   
6. Hit Save and close.
