There's been some comments about cheque payments. If a customer pays by cheque, in the eyes of the Law, it is proof that they are 100% satisfied with the quality of the work done. Any cheque that is 'stopped' after it has been banked by you gives you a cast iron case for winning in a small claims court. I was told this advice by the legal team of the FWC after I had a customer threaten to stop a cheque that the wife had written me, just because the husband thought she had paid too much for the job done.
Cheques for jobs are good things....
