Guidelines for pricing

I had a teacher who once said if you're not busy keep your prices low. If you're too busy raise your prices. Be careful of big jumps in your fees. 10% a year is a comfortable raise. Over a shorter period than you would imagine it becomes a signicant sum. You might also refer to the back of John Howard Sanden's first or second book, I don't remember which, where there is a chart outlining different fee structures.
