I record all my workorders and invoices regardless of whether or not there is money owed. I gave a client a "credit" so i charged an amount..lets say $150...as labor then did another labor charge that was -$150 to bring the total to $0.00. I have a work order attached to it and I cannot close the workorder and I cannot "receive payment" on this invoice because the balance is $0.00. Is there another way to do what I am trying to accomplish? I am thinking maybe the "refunds" area but this is not considered a refund.
