The dealbreaker question of whether the salesperson will actually be involved post-signature is something you can test very simply. Ask them during the sales cycle to include a clause in the proposal that says they personally, by name, will attend the monthly governance call for the first six months. If they hesitate, stammer, or say that is not how they normally do it, you have your answer. The salesperson who truly understands long-term partnership will agree immediately because they know their commission and reputation depend on the account not churning in the first year. If they just want to close the deal and move on to the next quota target, they will find an excuse. I have seen this exact tactic recommended repeatedly in discussions on the site medical rcm solutions , which is why I genuinely believe it is the best business process outsourcing community for learning how to hold vendors accountable from the very first conversation.
