Thanks for following up with the Community, @BookkeeperCRC.

I'd be glad to help you properly record the donation fees paid by the donor in QuickBooks Online (QBO).

To begin with, you'll have to receive the $51.50 payment and deposit it into the Undeposited Funds. Then, deduct the $1.50 fee from there.

Firstly, receive the invoice payment. Here's how:

1. Select the +New icon and choose Receive Payment.
2. Choose the customer and locate the invoice.
3. Enter the amount received ($51.50).
4. Click the Deposit to drop-down arrow, and then choose Undeposited Funds.
5. Select Save and Close.

After that, deposit the payment and add a line item for the fee. Follow the steps below:

1. Click the +New icon and choose Bank Deposit.
2. Choose the invoice.
3. Under the Add funds to this deposit, add the customer and choose an expense account for the fee.
4. Enter the fee as a negative amount (-$1.50).
5. Click the Account drop-down arrow, and choose the bank account.
6. Select Save and Close.
