Wasn&#x27;t the time spent to write this post worth more than 1.5k the OP is whining about?<p>While I agree that doing work for free can be a trap, I still believe that the one metric the OP dismisses (time spent adjusting the bill vs time spent just implementing the feature) is the most important: It might feel &quot;good&quot; to bill for every second but overall the benefit of being known as the &quot;good guy&quot; always outweighed the cost for me. I even once made the incredibly stupid mistake of billing (in the sum) for one more hour than I worked for them. I pointed that out and the response was: don&#x27;t worry, just deduct it from the next bill - and even if you don&#x27;t, you saved us so much money that we&#x27;ll find a way to make up for the difference by creative book-keeping.
