A lot of freelancers skip contracts for small or quick jobs because it feels like too much effort for something that will be done in a day or two. But I have heard stories where even a small project turned into a big problem because there was nothing in writing. At the same time, sending a formal contract for a fifty dollar task might feel strange to some clients. Do you use contracts for every single job, or do you only bother when the project is above a certain size?
