We have to A/R accounts but the payment is only posting to one of them. How do I move it to the correct one?

Good day, @BH5406.

Can you share with me the process of how you record these transactions inside QuickBooks? That way, I can provide you with the right steps in completing your task.

Once you create invoices, they will automatically be posted on your default A/R account. We can't assign open invoices to newly created A/R accounts in QuickBooks.

In addition, transferring funds from a default A/R account to another A/R account is unavailable in QuickBooks Online (QBO). 

Although, you can send this suggestion to our product developers. That way, they can review your request and most likely include it in future updates. 

Here's how to send feedback:

1. Click the Gear icon at the top and select Feedback.
2. Enter your comments or product suggestions. Then click Next to submit feedback.

Your valuable feedback goes to our Product Development team to help improve your experience in QBO. You can track feature requests through the QuickBooks Online Feature Requests website.

In case you have other concerns or questions in supervising your accounts, tag me in your reply. I’d be more than happy to work with you again.
