That isn’t the experience we want you to have, Stevenj3814.

There is no timetable for when the option to customize your company's purchase order form will be available in QuickBooks Online (QBO). We see consumer feedback as an opportunity to improve our products' numerous features. I'd suggest providing direct feedback to our engineers. They may investigate this suggestion and include it in future updates. Let me show you how:

1. Go to the Gear icon.
2. Hit Feedback.
3. Type in your recommendation in the Share your feedback field.
4. Click Next.
5. Follow the on-screen instructions to complete the process.

I've attached screenshots below for your reference:

On top of that, you can visit his page to keep updated with the latest software improvements and enhancements with QBO: Customer Feedback for QuickBooks Online. Alternatively, we can create custom fields to capture additional information for purchase order items. Here's how it's done:

1. Go to Settings and select Custom fields.
2. Click Add custom field. If you’ve already created a field, you’ll see Add field instead.
3. Enter the name of the custom field. Then, select the type of data that will go in your custom field: Text and number, Number only, Date, or Dropdown list.
4. Choose the category the custom field belongs to: Customer, Transaction, or Vendor. 
5. Mark the forms where you want the custom field to appear. If you want customers or vendors to see the field on a form (such as invoices, estimates, or purchase orders), toggle the Print on form.
6. When you’re finished, press Save.

You can find more details about the steps above through this article: Create and edit custom fields in QuickBooks Online Advanced. Also, to further guide you in managing your account and the growth of your business using QBO, I'd recommend checking out one of our support websites: QuickBooks Help Articles. It includes topics about account management, banking, and expenses, to name a few.

Please keep me updated if you have any questions or concerns about customs forms. I'll be by your side every step of the way. Take care and have a wonderful day.
