Hi there, @accounts414.

The option to create purchase orders or bill payments is unavailable on QuickBooks App. 

You'll have to log in to QuickBooks using a web browser to perform these tasks.

Simply sign in to QuickBooks Online and click the +New icon. Then, select Pay bills or Purchase order and record your transactions.

For additional reference, you can check out these articles:
 

• Create and send purchase orders in QBO
• How to track bills and record the payments

Keep me posted if you need anything else or if you have other questions in QuickBooks. I'll be here to help. Have a good one.
