Here is what I do in those situations. - Break down into weekly sprints. Write down a weekly list of tasks that will be done by a given day. - Put a price on each weekly sprint. Don't just break down the original price in n amount of weeks. No. Charge them what you would make in a week under normal circumstances. - Take half of the payment up front. The other half when you are done. This allows you to keep a good flow of cash while avoiding getting scammed. - Sell them on the fact that this is cheaper for them because they can always get stuff done in weekly sprints. There is no long-term commitment for either side. If they don't play ball with this option, then fire them right on the spot. Doing so will show them that you mean business. Seems right now they think your team is weak and can be bullied.
