Adding on to this, I also have this question.  My bank account is tied to QBO and a payment comes through that is for an invoice.  QBO lists in the details on this payment, in the bank transactions tab, the matched amount from the invoice and asks "Is this the payment for this invoice?".  I click confirm.  Now going over to the "All Sales" tab, the payment shows up as a "payment" that is "closed" and has a negative number in the amounts column.  When I click on "view/edit" it shows the correct invoice matched in the details.  However it is not listed as a paid invoice in the "all sales" tab, it shows up as a transaction instead.  I have read through here and people have said that transactions need to be linked to an invoice to show as paid, which it appears that they are already linked but they are not showing up as invoices, just as payments still.  Does QBO take some time to link the transactions to the invoices, or is something wrong with the way I am confirming the payments for invoices?
