I disagree, we are often asked if we take credit cards.
It is something we will be doing shortly.
We often survey/ quote for domestic cleans worth well over £250. Sometimes we do the work in 2 bits, other times people put it iff 4 or 5 weeks. If they could pay on a card, they'd have it all done at once and sooner.
It also comes into it's own when you get a rental clean to do and the owner lives a long way away. Instead of waiting for a cheque, they can pay over the phone.
Probably there isn't the need when dealing in small amounts of money. It once again depends on which end of the market you work at, market too and are successful with
