We created an account called "allowance" which is our allowance for doubtful accounts aka bad debt.

I need to write off the balance of an invoice to bad debt but am unsure how to do this.

I can go to refunds & credits and do a customer write off and apply it to the invoice but this reflects on the income state and only erases the balance from the customer account without doing anything to the allowance account created.

In other words i have no idea how to write off bad debt properly.

Please Help
