To expand a little: look over the horizon. Imagine you are thinking of expanding into the banking market at some point down the road. Customer A says, “hey, would you add a feature to your emoji generator to interface with the ACH system?” Stupid request, maintenance nightmare. But you might get paid to have one person get some exposure to the horror show that is banking APIs. Exposure that might later help you think a bit better when it’s time to start thinking about that market. Of course charge a LOT because it’s new and charge a LOT for the maintenance contract. Maybe it helps you estimate engineering and marketing budget, or maybe it helps you decide on a different expansion path. The converse is true too. Customer B wants hospital integration so they can add cute emojis to messages like “hey, you’ve only got four months to live. Have a nice day!” You’re not stupid so you know you never want to get anywhere near the tarpit of medical software. So you can confidently say “no” (phrasing it, “we don’t believe we could honestly provide the necessary level of support you’d require and don’t want to let you down blah blah blah”).
