Thanks for that Clinton, but I disagree that its a total wombat.
Something amusing on the bottom of a statement can make the difference in the time it takes some (not all) customers to pay up.

If followed up with a phone call at least they remember who you are - which is a start.

At the moment 90% of all customers pay up within the thirty days -its just the "evil" 10% that I want to bring in line - any constructive ideas - maybe not a rubber stamp (although I liked the idea of the horses head...........perhaps not)

cheers
