Good day, @geylicio.
It’s nice to see you in the Community. I’m here to walk you through the steps to change the posting expense account for your vendor transaction in QuickBooks Desktop.
You need to locate the transaction and open it to make the correction. Let me show you how:
However, if you’re referring to the assigned expense account of an item used on your transactions, follow the steps below to change it.
Here’s an article for more information: Add, edit and delete items.
This should get you back in line. Always know that you can count on me if you have any additional questions. Take care and have a pleasant day ahead!
Thanks for getting back to me. I’m here to provide some clarification about the changes made on your vendor transactions.
If you wish to only update the posting expense account of your current transactions, you can do so. However, please remember that to ensure accurate recording of your books, it's best to change all those that are incorrect.
On the other hand, changing the assigned account on an item automatically updates all your transactions associated with it.
Please refer to the same steps and articles I've shared above.
That should do it. I'm always here if you need anything else. Have a good one!
