Thanks for the replies,
its the domestic customers who we have chqs from. We dont invoice them every week, they just give payment in an envelope to the cleaner.
commercials pay direct to bank mostly, so not really a problem there.
When we do invoice our bank details are at the bottom.
I just thought a letter to explain that payments system is changing to become more enviro friendly and to make chqs redundant, might solve a few probs.
i'll have another think about it
