Hi there, colloranetworkse. 

I understand that your vendors need the product SKU of each purchase order you send. While this feature is unavailable, I'd encourage sending feedback to our Product Development Team to help improve your QuickBooks experience. 

Our engineers have been working on to provide ways on how we can improve our products and services through our customers feedback. I'll be sure to share this to them for future product enhancement.

For now, I want you to be updated with the latest QuickBooks news and improvements of the product by visiting our QuickBooks Blog.

For additional tips and resources while working with your vendor transactions, you can browse a topic from this page: Expenses and vendors.

You can always find me here if you have any other concerns or further questions about purchase orders. Stay safe and have a good one
