Hi there, @activeg2014.

There are several reports available in QuickBooks Online that allows you to view all the purchase orders. Among these are the following:

• Open Purchase Order List - This report shows PO's grouped by vendor.
• Open Purchase Order Detail - This report shows PO's grouped and its details including total, received, and balance quantities and amounts.
• Transaction List by Vendor - This report shows all transactions grouped by vendor. You can customize this report to show only specific transactions like Purchase Order.

 Here's how to run a report:

1. Go to Reports.
2. Under Expenses and vendors, choose your preferred report (Open Purchase Order List, Open Purchase Order Detail, or Transaction List by Vendor).
3. Filter the dates and other information by clicking the Customize button.
4. Hit Run report.
