First, I just want to say that this is a great topic to discuss.
I choose not to take customers more than I drop them. When you can just tell that the customer is a never happy one, I don't take them. That keeps from having to drop a whole bunch of them.
As Boston stated, I weed out more bad customers from the get go before dropping a customer becomes an issue. There are so many red flags to look out for, that you should be able to do this. In fact, I rarely ever have to drop a customer.
Also, keeping it in context, to drop a customer, you would have had to deal with them as a customer to begin with.
I think you may be overstating the readyness of the recommendations.
Perhaps this is because its something people suggest, but bear in mind that theres a context here - someone has been troubled enough by a customer to post on a public Forum asking for help to deal with a problem the customer is causing. In other words, the impetus to post usually indicates there's a significant issue there to start with.
Exactly. I know you read a lot of posts that suggest that someone should drop their customer, but its because most of us do not post anything too trivial about our customers, usually its a pretty big deal.
When you start to get more customers than you can handle (and I can handle a lot of them) you will also start dropping the ones you don't want to waste time with.
BTW- Every "customer" does not automatically mean more money.
Absolutely. Obviously you are going to deal with the occasional idiot or time waster, thats just a part of business, but there comes a certain point in your business (especially when you are doing well), that you will need to drop the less profitable more painful customers and concentrate on the customers that make you money with less headache.
===========================
My overall opinion in the matter is that it will happen and that it should happen from time to time. If you are not cutting off the dead weight (those who cause you pain or cause you to profit less), then you are doing something wrong. As Jimbo stated, you should eventually get to the point to where you have so much business that you can pick and choose your customers. If you are not there in 20 years, then maybe your doing something wrong.
That said, some of us have less patience than others and some of us need the work more than others. I personally turn away a lot of business simply because a customer wants me to do something the wrong way or they want me to cut corners in order to drop to the price. I also turn away customers who want to argue prices with me. Personally, I do not need those customers. I have plenty of good customers who are willing to pay what we charge and want the job done right the first time.
