I'll share the steps on how you can match your sale invoices with your bank receipts. All you have to do is categorized and match your downloaded transactions with QuickBooks from the Banking page. Let me guide you how.
Go to Banking, then select the Banking tab.
Tap the Update button. This updates all of your bank and credit card accounts.
Find a downloaded transaction with the Match option in the Action column.
Select the downloaded transaction to expand the view.
Review the Matching records found in QuickBooks. This is the possible matching transaction you already entered in QuickBooks.
If this is the correct match, close the open transaction.
