Change in Square Integ app caused dup transactions which I deleted. Now I have neg AR amt ($-334; total of the deletions) on bal sheet. How do I clean this up?

I got you, treasurer134.

I can help fix your accounts receivable (A/R) issues that are showing as negative

You'll want to make sure to apply the credit to the correct invoice. To do this, you can follow the steps below:

1. Click + New.
2. Select Receive payment or Receive invoice payment.
3. Select the customer, then the credit and the invoice.
4. Select Save and New or Save and Close.

On the other hand, you can apply the credit to a new invoice. 

Here's how:

1. Click + New.
2. Select Invoice or Send Invoice.
3. Create the invoice.
4. Select + New. Then select Receive payment or Receive invoice payment.
5. Select the credit and then Save and New or Save and Close.

Once done, you can run the A/R Aging Report to see the changes. 

In addition, QuickBooks automatically downloads the latest transactions. You can match them with what you've already entered in QuickBooks Online.

As the invoice was deleted since it was a duplicate transaction, this doesn't really help.  I wanted to know if there was a way of deleting the corresponding (now) unapplied payment.
