Thanks for joining us here, Melanie.

For now, we're unable to edit or customize the Purchase Order form in QuickBooks Online. Transaction forms that can be edited and customized are only limited to sales transactions. This includes invoice, estimates, and sales receipt. 

We'll send a feature request about being able to remove these details when creating POs. Our engineers are always on the lookout for customers' feedback and suggestions. They review them and checked if they can be used in the future updates.

Visit us again in the Community if you need more help when creating transactions in QBO.
