My brother is a self employed licensed contractor in CA. He recently learned that person he had employed to schedule calls & billing never invoiced his clients for work he had provided. Most of his jobs are COD & generated enough income that he didn't keep track of the jobs she was supposed to be mailing out. She is no longer with him & he has recently learned of numerous invoices which never were billed to the customers, totaling several hundreds of dollars.
Recently he presented a few invoices to a client who agreed the work was done but refused to pay since it had not been billed in a timely manner. He explained the situation, but she refused to listen & has not paid. Is she correct and is there a time limit to bill for services. I understand billing late is not sensible for a business.
