It sounds to me like sales is future-selling, or selling dev time when you actually don't have the time to be sold. I would advise having clear discussions with sales and management levels, to identify the goals of your team and the company. If the best thing for the company is to do this 1-off consulting work (from what I gather, that's what it is), then you may be surprised to find that's what you're doing exclusively. If the best thing is to improve the core product offering (my vote), then you should not do these 1-offs at all. It all starts with clear communication between departments. I would say it's less about your team, and more about what your team is tasked to do against your will.
