what is the most professional yet stern way to collect debt from customers that have a unpaid balance? I have two customers that have given me every excuse imaginable , car broke down, I'm sick, lost my job , etc.. i have given up on calling and sending out invoices each month. I want your professional / legal opinion on the best way to settle a situation like this. i have let small debts go before but both of these accounts have over $300 each on the books. if they were senior citizens that were really sick or financially struggling i would let go. hell i would probably take care of there property a time or two if i was in the neighborhood. but both of these customers are young ,employed, in good health, just wont pay there bill.
