Where will I see my Brex transactions on QuickBooks Online?

Your Brex transactions imported through the bank feed will automatically appear in the Transactions tab > under Banking > Brex card > For review. After manually exporting your transactions from the Brex dashboard (if you are using the Expenses data option), they will be matched to the bank feed records automatically as long as your books have not been closed on QBO.

You will then have the option to confirm if these matches are accurate by clicking on match on the right-hand side of each transaction on the banking feed. You should not see any duplicates.
