My boss wrote up our way of communicating those estimates: http://www.apsis.io/blog/2016/04/18/communicating-estimates http://www.apsis.io/blog/2016/04/18/communicating-estimates As a rule we have a few techniques that have produces our most accurate estimates: One: since we're a team we get more than one person to estimate independent of each other, then we talk about it. If you're solo, you can still have a trusted friend do the same. Two, we measure the uncertainty: client says they have a file ready to go once you sign. Client hasn't designed the login page. Client has spec but like most specs it's under specified. Each piece is going to take time to unravel. We try to make sure we look at that uncertainty when estimating. Three: we always remember that project management takes up tons of time. Even if there is an outside manager you have to manage your workload and communicate to your client. Make sure you factor it in.
