Problem
You need to remove an exported credit from your customer. This is due to the payment inadvertently being entered a second time and generating credit to your customer.
Solution
Find and go to the invoice.
In the invoice screen, click Add an adjustment invoice.
In the adjustment invoice, add a task and designate an amount equal to the credit you want to remove.
Go back to the original invoice and click Collect and apply payment.
In the Collect and apply payment screen, select the credit you want to remove.
Apply it to the adjustment invoice you created in step 2.
When finished, click Save.
Go back to the adjustment invoice and add a negative payment equal to the credit you are removing.
For example, to remove $100.00, enter "-100.00."When finished, click Save.
Remove the task from the adjustment invoice and click Save again.
Note: The task does not need to be the same as the original.
