Going to be freelancing as a web designer and web developer soon, creating websites for local businesses. I'm expecting to use a payment plan in which they pay a down payment of 50% to begin work, and they pay the remaining 50% after the website goes live.
I will be charging fixed costs instead of an hourly rate, so how do I go about deciding what the cancellation fee should amount to at different points in the project? Do I just estimate the % of the total work that I have completed and bill them on that? This doesn't seem very set in stone and it is the reason why I ask.
