Is there some general rule to follow when delivering a project after the date that was agreed upon?
Let's say you have one month to prepare the project but you deliver it in six weeks. At what point you should offer some kind of compensation to keep relations good? How big should be the compensation - deduct how many percents from final price? Or what other compensation should I offer, if any?
I know this should not happen in the first place, but when it does, what are proper manners?
Thank you for your answers.
