How do I use different payables accounts when using bills

I appreciate you for reaching out to us with your concern regarding QuickBooks Online, deborah.

I understand that you have been using the A/P account field while creating bills in QuickBooks Desktop, and it has been useful for you. 

However, this feature isn't currently available in the online version. I suggest sending your feedback directly to our product developers. Your input is valuable to help us provide a better experience for QuickBooks users. Here's how:

1. Click on the Gear icon. 
2. Select Feedback under Profile.
3. Enter your suggestion, then click Next. 
   

Additionally, bills will automatically be posted to the default AP account.

I have some resources that might be helpful for you in managing your vendors and transactions:

• Enter expenses, pay bills, write checks, and manage suppliers.
• Manage your money-out payments. 

If you have any further concerns while using available features in QBO, please don't hesitate to ask. I'm here to help.
