Hello @Muz123,

I appreciate you for getting back to us here in the Community. Let me chime in and provide clarification about the response above.

The QuickBooks Team answering questions here in the Community forum are live support users. To hide some information, I recommend customizing the Master template from the Custom form styles section. 

Here's how:

1. Click the Gear icon in the upper-right corner.
2. Select Custom form styles.
3. Search for the Standard (Master) template.
4. Press Edit. 
5. Go to the Content tab.
6. Click the pencil icon in the upper-right corner. 
7. Under Header, uncheck the boxes to remove your information.
8. Below Columns, uncheck the Description box. 
9. Hit Done.

Once done, please proceed with printing the purchase order to view the results. The changes should reflect after saving the template.

For more information, as well as how to run a purchase order report, I recommend the following article: Create purchase orders in QuickBooks Online.

Drop me a comment below if you have any other questions. I'll be happy to help you some more.
