Thank you for getting back to us, @celiarlisman.

I understand you were advised that you can customize a purchase order form with QuickBooks Online Advanced. Please know that we can't customize a purchase order form in QuickBooks Online.

Thus, I strongly urge you to share your thoughts with our software engineers, as also mentioned by my colleague above. They carefully examine customer feedback, especially when determining how to improve QuickBooks.

I'm also adding this article to help you manage your purchase orders in QuickBooks Online: Add purchase orders to expenses, bills, or checks in QuickBooks Online.

Feel free to comment below if you need further assistance in managing your purchase orders. I'm always here to help. Have a great day.
