When we quit generally taking checks a few years ago, my main concern was our regular customers who had been writing checks with us for twenty years. After some thought, I started making a list of the names of all check writers, (Just the names, nothing more), after three months I printed out the list and quit taking checks UNLESS your name was on the list. I and ONLY I can add names to the list. Our regulars are happy, and we haven’t got a bad check since.
