i always do an audit on every job. sometimes people want upholstery cleaned so they can sell it.
my advise would sometimes be NOT to have it cleaned because you probably wont recoup the cost back but after doing a quality job that they may well wish to keep the suite thus saving them a couple of grand bying a new one, also on the point of dropping prices, i agree with some of the other posts, just because some people live in poorer parts of town, that does not mean that they are dictated cby a low price,
i find that most people want a quality cleaning service and are willing to pay for that, i always say to people who do ask about lower prices to check that the other firms are fully quallified and insured, because maybe the real cost will come to them if something does go wrong!!!
