I agree with Jay. Do not let this get out of control. We have had similar problems. Once we let the client know our concerns, they come around. However, we have been forced to refuse to perform future searches until the invoices are paid in full. We will not tolerate 90 days past due. If an invoice goes over 90 days past due, we turn the matter over to our attorney for collection and refuse to work for the client again. Remember we are abstractors not banks.
