My neighbor owns a construction business he started about 30 years ago. The last couple of years has been a struggle for several reasons; his wife became very ill; projects were completed but not tracked for payment so he has both old and new debt that he wants me to help collect. His office manager of many years retired and the replacements have not worked out. I have some experience in debt collection but not construction. He has not been successful in finding the right person for this job and he is convinced I am the person that can turn this around. And, I think I can certainly do more than is being done but I need to know the most efficient and law abiding process to get cash flow to his company. Since some of these debts are up to 6 months past due can I still start the collection process with the Preliminary Notice.
