How can i change a payment on a supplier account from expense to bill payment

I've got the steps on how to apply the expense as bill payment, @garybrown-blueyo.

 You can change the account to Accounts Payable. This will create an available credit, which you can link to the bill.

Here's how:

1. Open the expense transaction, and go to the Account details section.
2. Change the affected account in the ACCOUNT column to Accounts Payable (A/P).
3. Click Save and close.

Once done, pay your bill and apply the credit.

1. Click +New.
2. Select Pay Bills.
3. Select the bill from the list. You'll see the available credit with this vendor in the Credit Applied field.
   
4. Select Save and close.

To know more about the process, you can check out this article: Manage Vendor Credits.

I'm also linking this article on how to record a vendor credit in different scenarios: Vendor Refunds.

Get back to me if you have other concerns about applying vendor credits. I'll be around to answer them all for you. Keep safe and have a good one.

I don't see an Account Details section on my screen, so your process does not work for me, QB Online. I would need to see screen shots.

Thanks for chiming in on this thread, @NEBC_Bob. I'd be glad to provide insights into your concern about finding the Account Details section in QuickBooks Online.

Please know that QBO released and updated some features, including the Account Details section. Currently, it's now displayed in the Category Details section. You can refer to the screenshot below for your reference:

To change the affected account, go to the Category column under the Category details section. Then, you can continue following the steps provided by my colleague LieraMarie_A above.

I found this YouTube video that addressed the issue, which might help explain what I was trying to say. It's less than 2 minutes long, and fixed my problem. Her screen matched what I saw on my screen, so it was easy to fix this way.   https://www.youtube.com/watch?v=nH7xRvJ3-M8   I realize this is an outside vendor, not an Intuit team person but it worked for me. I hope you don't mind my posting it here.
