Hi there, @ keynq.

You’ll first need to check the Venmo history to see if the transactions are correct. Then, manually match the transaction to your QuickBooks Online. I’ll guide you how.

1. Go to the Banking menu, then select the Banking tab.
2. On the For Review column, choose the correct transaction. 
3. Select a customer or vendor name from the Select Payee drop-down.
4. Check that the selection in the Category field is accurate, or choose a more specific Category.

Then, here’s how to manually match the transactions.

1. Click the transaction to expand the view.
2.  Review the Records found. These transactions are ones you already entered in QuickBooks.
3. Review the Deposit to field on the forms.
4. When you’re done, select Match.

Once done, you’ll need to record a Split for the fee. You may follow the steps below.

1. Select the left Banking menu and select Banking.
2. On the For Review tab, select a transaction to open it.
3. Select the Split button to open the Split Transaction window.
4. Select a Category and enter an Amount for each category to assign to the transaction until the total amount matches the downloaded amount. 
5. Select Save and Add.
