I would have to agree with Appleby on this. However, I do not feel comfortable charging for a full hour for 20 minutes
I fully understand this and I struggle with this myself. There are many times I'm lenient on this and will cut someone some slack. I rarely do it with business unless I was really there only a few mins and they are a really good customer OR I'm doing a big project for them and I might make a few quick stops while I'm in the area etc. I won't charge them an hour for each of those obviously.
What I've gotten into when not charging the full service call fee is this...a few times, being nice, I haven't charged it. Then I've had the same customer call and say "Hey I've got this little problem, I know it will only take you 5 mins. Why don't you come on out and I can give you $20." Now what? I can't say that I stick to my fees all the time etc because they were the beneficiary of my generosity last time. It puts me in a very sticky situation when I've got to say, "No I'm sorry I've got to charge my full fee." And if I do agree to some kind of break, not what is going to happen next time? I've set a precedence and it's my fault.
But again, I'm a softy at times. I drove 18 miles one way to a new customer's place one day and it was an elderly couple who was sure their machine was dead. From the sound of it, I thought they had a video card problem or maybe a PSU problem because they said the machine sounded like it was running but the screen was blank. They had hooked and unhooked the monitor etc. I go out there and press the power button on the monitor (which I asked them about on the phone) and presto, it came on. I charged them 1/2 hour because I felt so bad and they ended up paying for for 3/4 hr and trying to pay me for the whole hour. So yes I do break my own rules at times, but for the most part I stick to them.
I think the one thing that makes it easier for me to stick to my rule is this...I offer everyone the option of bringing their pc in, even if they call requesting on-site service. I explain the charges and tell them if they bring it to me, it will obviously be much cheaper if it's a 15 minute fix. They know going in what my fees are and it's not a surprise. They know they are taking the chance of it being a quick fix but for alot of people, unhooking their machine, loading it up, driving 15 minutes, dropping it off, coming back to get it, driving back home, hooking it back up....its worth the gamble to have me come out.
