So I have been doing websites as freelancer now for some time. Couple clients likes to do small scale development now and then to their site, which is great but the problem is that they have always tight schedule. So example scenario:
Week 1: They ask how much it would cost to do this feature. I let them know and they say they think about it.
Week 3: They say they want it, but they need it tomorrow. Well obviously my schedule for next day is full already.
Now the problem... I would like to do this and since usually the development is something simple and quick. Max one hour billable. But that they want this to be done fast gives problems. I have said multiple times that these things should be scheduled at least few days beforehand or ideally week(s) before. What would you do in my shoes? Ask higher fee for quick job? How much is suitable? 10%-15% extra?
