Hi aaronrothmail-gm,
It's wonderful to hear that you're making use of the bank feed feature in your QuickBooks Online account. Being able to match your downloaded bank transactions makes reconciling your accounts a breeze. Let me explain how the matching works with your account balances.
When you click match as you review your downloaded bank transactions, you're matching them to an existing transaction that has been entered previously. When you entered the transaction, it resulted in a difference in the QuickBooks value of the bank account. Matching the transaction recognizes that it has been already entered into your system, so no changes are made to any amounts. You can review this article to view the process in more detail: Categorize and match online bank transactions in QuickBooks Online. You can let me know if you have any other questions about matching transactions.
Have a terrific day!
