Very good points. One thing I don't really get though: "2. [...] If something can be done in a few hours, then it should be free."

Why so?

[tptacek]

Because a client who is reliably paying you for days of work is worth a free hour or two now and then, and because the precedent that you will work for hours instead of days will come around to bite you in the ass later on.

This approach is great - giving small things for free, but isn't working for every clients. It's horrible for you when your customer is't paying a lot (small projects, low prices etc.). They are overdemanding, don't like your work, put a lot of changes and thinking that you should't do it for free.

You'll soon learn to cut these customers off. They are bad for your business, stress, and will stifle your growth.

The idea behind this is that you bill in weeks and deliver real business value so you don't have clients doing 'small projects' or low prices.

The approach is self selecting and self correcting.

Exactly. No real projects are small. Anything less (IMO) is a favor and should be considered a marketing/sales event.
