Did you figure out an answer yet? On the Bank Transactions page of QBO, sorta upper right corner, there is a Link Account button. You can use that to link Sutton Bank to QBO. There are ways to sync Square to QBO, but none of them ever worked for me, so I haven't tried again. I create sale receipts where I collect Square funds, then at the end of the day I click on New/Bank Deposit, choosing those receipts and then adding the Square fee down below. You will need to add an expense account called Square Fees if you don't have something like that already. When the Square deposit hits your bank account, you will be able to match it to QBO deposit.
