Tell me if this sounds familiar. You land a large job to renovate a home that promises to be a massive money maker and make your bottom line for the year go from red to black. You receive your signed proposal, and as the work begins you realize that the customer is going to be difficult. They change their mind constantly, have unrealistic expectations on timing, and - most importantly - they think that you are doing X but in reality, you are delivering Y. You’ve already sunk too much into the job to cut bait and you worry about bad reviews on Yelp, HomeAdvisor, etc. - so you soldier on. But to no avail. The homeowners have convinced themselves that you are trying to rake them over the coals, and refuse to pay for any change orders and are even mentioning legal action.
