Thank you for reaching out on this and welcome to our community!
Purchase orders are part of the Mange Suppliers and Bills function which is available on QuickBooks Online Plus.
Hope this helps and please let us know if you have more questions. Thank you.
Thanks for posting here, @brucehayes,
We recognize the need for all QuickBooks Online accounts to have purchase order templates. At the moment, our engineers have not released an update on when this feature will be available in the program.
Before our product engineers release product updates, they are going through a wide range of feedback. They try to navigate a path forward with accessibility leading and wanted to be very thorough with the enhancements to make our program efficient to use.
Please know that our engineers are working hard toward this goal, but we can't provide the turnaround time since they work on this internally. Don't worry, when there are new updates for our QBO products, it will be communicated through in-product ads.
If you have any questions or need further help with anything in QBO, feel free to visit us anytime. You can also mention my name on your posts and I'll be more than glad to help. Have a nice day!
