I'd suggest going to the Pay Bills page to pay multiple bills with one payment. From there, you're also able to pay bills by batch.
Select + New.
Under Vendors, select Pay Bills.
Choose the appropriate Payment account and enter or verify the Payment date. Use the account from which you pay the bills. To pay one bill from different accounts (for example, part by check and part by credit card), or to record separate payments on different days, you must enter each partial payment separately.
(Optional) Select Filter to narrow down the list of bills to view only those you specify. Select Apply when done.
Select the checkbox for each bill to pay.
Enter the amount of the payment to be applied to the open bill. If available, you can specify the amount of any credit to apply in the Credit Applied column.
