Hey there, @jennifer3.

It's a pleasure to see you here in the Community. I'm here to share some information about customizing Purchase Orders in QuickBooks Online (QBO).

The option to customize/remove the lines Approved By and Date on the Purchase Order is currently unavailable in QBO. I can see how this additional options and functionality would be helpful for both you and your business and I encourage you to submit feedback. These requests and suggestions are forwarded directly to our Product Development Team for consideration in future updates.

You can submit this from within your QBO account by selecting the Gear icon and Feedback or by going to the following link: QuickBooks Online Feature Requests. Please know that I'm going to submit feedback from my side as well.

Feel free to leave a comment down below if you have any follow up questions. I'll get back to you right away. Have a wonderful day!
