On an episode of TechStars one of the companies gets flown to meet Dick Costolo, CEO of Twitter. When asked for a piece of advice Dick offers this up, “Don’t get swayed by clients who will offer $100,000 more if you offer a bunch of features you really weren’t planning on building. You want to make sure you don’t get this barnacle on you that you have to scrub once a month.”

I’d add, ‘try’ not to alter your road map for a client. As great as the deal is, as much as you want to close it and do whatever it takes to close the deal, once you get into this cycle you will go from being a software/product company to a pro-services company. Once in a while it might make sense, but be careful, once you start to slide down that slope it is hard to turn back.
