Hello there, @LCecchini. I'm here to ensure you're able to receive inventory from your purchase order in QuickBooks Desktop (QBDT). This way, you can keep track of your inventory and record them accordingly.

The steps provided above are for the online version of QuickBooks. That's why you're unable to locate the Action pull-down menu. With QBDT, you can receive inventory with or without a bill after you record a purchase order. This way, your quantity on hand for each item and the payable to the vendor will be updated. Let me guide you how.

1. Go to the Vendor menu.
2. Select Vendor Center.
3. Click the New Transactions drop-down.
4. Choose either the Receive Items and Enter Bill (Receive inventory with a bill), Receive Items, or Enter Bill for Received Items (Receive inventory without a bill) option.
5. Fill in all the necessary details needed.
6. Click Save & Close.
7. When you're ready to pay the bill, proceed to Pay Bills. Then, go to Entering bills against Inventory when you receive the bill for the inventory.

I've attached a screenshot below that shows the third and fourth steps.

Receiving inventory is part of your usual A/P workflow in QBDT. To see the complete list of workflows and other vendor-related transactions, refer to this article: Accounts Payable workflows in QuickBooks Desktop.

Let me know how it goes in the comments below. If you have other concerns about receiving inventory items, purchase orders, and vendor-related transactions, I'm just around to help. Take care always.
