The problem with most home users is that they do not call often enough. After running my business for the last 10 years, I can tell you from experience that I need approximately 30 home users to equal one small/medium size business to support. Home users are famous for calling me and saying "Do you remember me?"
That's because it's been an average of twelve months since their last service call.
On the opposite end of the spectrum, you have a home user who will not follow your advice, and continually is riddled with malware and expects you to fix it every other week, under warranty. Try to explain it's their own fault and not covered under warranty, and you're in for an argument that keeps you from making money on other work for the next hour.
Home users don't want to call support unless its free and they will call you and try to get information for free. For example, a customer calls me the other day, who I haven't heard from in over five months and asks "Do you have any idea why someone couldn't record a DVD? Could it be software?"
I assume they are talking about a system I worked on, so I ask a bit and I soon learn her sons girlfriend got a DVD burner for her birthday. Apparantly they installed it themselves but either it does not work or they do not know how to use it.
Because I fixed her last problem via remote access, she wants to know if I can remote access into her sons girlfriends PC and try to resolve this issue.
I explain I cannot do that and that I offer remote access only for specific customers with certain types of problems.
The next, inevitable question is, "Do you know anyone who can?"
I say "No, but if you bring the PC to my shop, I'd be happy to look at it for the standard rate."
That usually results in "Ok, thanks. Good bye." And it did.
I also have folks call me and ask "Do you do telephone support?"
I ask, "Are you a customer of mine?"
They say, "No."
I ask, "How can I support something when I have no idea what it is or if it's put together properly?"
The response one guy gave me was not asking how much I charge, where I was located or what my hours were, but rather "sorry, I guess I have the wrong number."
Consumers get so frustrated dealing with the retailers and manufacturers, they'll start calling every place in the phonebook looking for help, and after spending their money on the item they are frustrated with, they are NOT usually looking to pay for help. This always blows my mind, that folks that have never been a customer, are calling me randomly from my ad in the Yellow pages, which costs me money every month, on a cellphone, which costs me money every minute, to interrupt my business to answer their questions when they have no intention of buying anything from me.
Business users need things fixed and they need it fixed yesterday. Just like a consumer, but you can charge a business more and they will need you more often. You also rarely get a bad check from a business. Imagine going through the expense of driving to a customers location, spending an hour and a half to fix the problem, and being a nice guy, only charge for one hour, and when you drive home and do the paperwork for the service call, then drive to the bank to deposit the check, a week later you discover the bank has charged you $15 for a bad check and sent it back to you.
Home users are, generally speaking, a waste of time. They are thankless, want onsite support so they can look over your shoulder and ask you what you are doing each step of the way and, since most people bill hourly, want you to do it in an hour. And if you fix it in 10 minutes and the minimum billing rate is one hour, guess what? They want you to stick around the extra 50 minutes to make sure they get the hour they are paying for! But if you go 10 minutes over an hour, they'll be upset if you charge them for 2 hours! So, if you are good and efficient, you are punished.
There are exceptions, of course, but generally speaking, the majority of consumers have no money and don't care how, or if, you stay in business.
I estimate if you ONLY support consumers, you would need about 450 of them for ONE technician to have enough consistent work for one year. And that includes all the headaches and frustrations I just mentioned x450. Just to make ends meet.
