I appreciate your input on this matter, @DLo27. I'd like to clarify the current capabilities regarding Purchase Order (PO) in QuickBooks Online (QBO) and provide options that can help achieve your goals.

While you can customize templates for various sales forms, such as invoices, estimates, and sales receipts, through the Custom form styles feature, it is correct that the option to create a fully customizable PO template is currently unavailable.

However, you can adjust existing POs by adding custom fields, default messages, and personalizing transaction numbers. Here’s how:

1. Navigate to the Gear icon, then Account and settings.
2. Click the Expenses tab and the Edit icon for Purchase orders.
3. Toggle on Custom transaction numbers.
4. Enter your message in the Default message on purchase orders box.
5. Click Save, then Done.
   

For more information on adding custom fields to your PO, please refer to this article: Add custom fields to sales forms and purchase orders in QuickBooks Online.

Additionally, you can utilize third-party applications that integrate with QBO, creating PO templates tailored to your specifications.

I recognize the importance of being able to create and customize your PO. I encourage you to share your feedback directly with our Product Development for consideration in future updates. 

1. Select the Gear icon, then choose Feedback.
2. Enter your comments or product suggestions.
3. Select Next to submit.
