How do Include the customer Purchase ordering QBO. must print and also appear on invoice and Packing list?

Hello, @userlindsay1.

Allow me to share information about purchase orders in QuickBooks Online (QBO).

If you want to convert a purchase order (PO) to an invoice or appear on the packing slip, that feature is unavailable in QuickBooks. The reason is that POs are for vendor transactions and invoices and packing slips are for customers.

However, we can  add a custom field to your invoices so that PO number will be placed on the upper part of the item details section. Let me guide you on how to add a custom field.

Here's how:

1. Go to the Gear icon, then select Custom fields.
2. Select Add custom field.
3. Enter a name in the Name field.
4. Click the Purchase Order checkbox.
5. If you want to show the custom field on printed and delivered forms, switched on Print on the form.
6. Then select Save.
   
   

You can refer to this article for more details:Add custom fields to sales forms and purchase orders in QuickBooks Online.

Additionally, you'll want to add an accepted purchase order to a transaction for your supplier. For detailed info, please refer to this link: Add purchase orders to expenses, bills, or cheques in QuickBooks Online.
