Yes, customizing a different layout design for your purchase orders is something you can do in QuickBooks Online. I'm here to guide you through the process.
There's no direct way to create a custom form style for purchase orders. However, they automatically follow the Standard default template in your Custom Form Styles. So, if you want to have a different layout design for your purchase orders, you'll need to edit the Standard default template.
Here's how to do it:
Click the Gear icon on the top-right corner.
Under Your Company, select Custom form styles.
Locate the Standard template. Then, press Edit.
Edit the form into your desired layout design.
Click Done.
Once done, create a purchase order. Then, click Print at the bottom of your screen to check if your newly designed layout has been applied.
