Prompting Admin Password For Item Receipt

You may consider having a 3rd party inventory management app to integrate with QB Desktop. There is no approval feature to modify orders. Your head of warehouse will be able to 

Print: It allows the user to print purchase orders directly from the handheld device.
Edit: It allows the user to modify purchase orders.
Receive: It allows the user to mark items contained in a purchase order as received and to create an item receipt.

Create: It allows the user to manually create purchase orders.

I know this functionality would be beneficial to your business, SergioHK.

As of now, the ability to prompt the admin password when deleting or modifying an order isn't possible in QuickBooks Desktop. Since this feature isn't added yet, I'd recommend sending feedback directly to our Product Development team. This helps us improve your experience and the features of the program. 

Here's how:

1. Go to the Help menu and then select Send Feedback Online.
2. Choose Product Suggestion.
3. Add the type of feedback.
4. Type in your feature suggestion.
5. Once done, click Send Feedback.

You can also search for a third-party application that offers this functionality. Then, integrate the app into the program.

Additionally, I've included an article that'll help you assign a unit of measure in QuickBooks. This ensures you can easily track your items: Show Quantities, Prices, Rates, and Costs for an Item.

I'm only a few clicks away if you need assistance in managing your inventory in QuickBooks. It's always my pleasure to help you out.
