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, select Brex card and then 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 if your books have not been closed on QuickBooks.

You'll then have the option to confirm whether these matches are accurate by clicking Match to the right of each transaction on the banking feed. You shouldn't see any duplicates.
