After creating Purchase order, while trying to send that to the customer, the description space doesn't look good. is there any other way to custom or edit that space?

I know how convenient it is to customize your purchase order according to your preferences, cnrqbo-greenbroo.

In QuickBooks Online (QBO), the purchase order formats are set as default and you won't be able to customize it. Customization is only available for sales transactions such as invoices, estimates, and sales receipts.
