have to agree with post, not to go around collecting, cost time and fuel and if customer in
and i don't really like cheque, i let customers know it cost me and they
though i still do accept them, i encourage to do bank transfer, most love it, only get a few chq's now

i have a6 invoices printed bank details on back and yes PLEASE PUT DETAILS WITH PAYMENT!!!
some still forget
and agree with A S put a little personal note where you can
i also put a little advert for other services at bottom of invoices, like insides or gutter clean so on
worked well for me and made some money
