>How do you handle the following situation, when a customer is asking for a specific feature. Note that I don't want to add this feature just for this customer; even though nobody else asked. And, who knows, nobody else may never use this feature. But I would prefer to make it a standard feature. To create this feature, it would take me about 3 days. I feel it may not be fair to charge them for all 3 days. But they should pay for some of this work (otherwise, I would never started it). What percentage or part of the development time would you charge your customer?

In my son's company he asks the customer if he/she will allow others to have the same new feature. If it's OK, he/she typically pays one third of the estimated cost using standard consultant price (high rate). If he will not allow others to have the new feature, he pays the full price. When given the choice, almost all customers accept to share the feature (and the cost) with others.
