I appreciate you for returning to this thread, @lizraimo. 

I understand the importance of the negative amount to show after converting your purchase order to bills in QuickBooks Online (QBO). For now, I suggest contacting our support team. They have the necessary tools to check your account and initiate a screen-sharing session to investigate this issue. 

Here's how:

1. Go to Help.
2. Select the Search tab, then choose Contact Us.
3. Type in your issue or concern in the field.
4. Hit Continue.
5. Click the Chat or Callback option.

For reference, check this article: QuickBooks Online Support.

Additionally, you might want to check these articles to help you track bills and how to email your bills to get them into QBO:

• Enter and manage bills and bill payments.
• Email receipts and bills to QBO.

Let me know if you have any other concerns about purchase orders or bills. I'll be around to provide further assistance to you.
