@rdylina I know that it is not possible to bulk change the Payment Account for the Expenses or Bill Payments directly in QuickBooks Online, but if you are looking for an alternative way of doing that you could try one of the third party data import/export utilities that have the ability to batch update transactions.  One that I am very familiar is Axis Online and it has a free level you can use to try out.
