I do not practice in the area of small debt collection. I do not think one would learn much from UCC-1 filings except who the other creditors are.
Some small creditors insist on credit card payments.
Others have check guarantee services. Perhaps an example on your part would help. I can order books by phone. I suspect that if I stopped paying for my books, I would stop getting them. A lot of business is cash, check, or credit card and carry.
