Hi @HP West Inc,

I'll take care of your query about the expected delivery date on purchase order transactions.

I have replicated this on a QuickBooks Desktop (QBDT) 2016 version and confirmed that the feature is available. I have already provided the steps above so you can see the Expected Delivery Date box.

In case you missed it, here's how:

1. Go to the Vendors menu.
2. Select Create Purchase Orders.
3. Tap the Formatting tab.
4. Press the Customize Data Layout button.
5. Tick the checkboxes for Expected.
6. Hit OK when done.

To learn more about the 2 Accounts Payable workflows in QBDT, see this article: Accounts Payable workflows in QuickBooks Desktop. One workflow consists of bills that have a purchase order, while the other only has bills. 

You're always welcome to post here in the Community in case you need further assistance. I'll get back to you as soon as I can.
