How can i change my Purchase order template ? Because the existing template is not enough for the explanation of Purchase order.

Hi there, sale.

For now, we're unable to edit or create another template for Purchase Orders in QuickBooks Online. We can only create templates for these following transactions:

• Invoice 
• Estimate
• Sales Receipt

Let me also share these PO-related reports in case you might need them in your future tasks:

• Copy an estimate to a purchase order
