I can see how the functionality to use Purchase Order Fulfillment worksheet in QuickBooks Online would be beneficial to your business, NLS2. I'm here to share some details.

As of now, the Purchase Order Fulfillment worksheet isn't available in QuickBooks Online. I'd recommend sending a feature request directly to our Product Development team. This helps us improve the features of the program. 

Here's how:

1. Go to the Gear menu and then select Feedback.
2. Type in your feature request in the description box.
3. Once done, click on Next.
   

You can also track feature requests through the Customer Feedback for QuickBooks Online website.
