It's a nice thought but it doesn't have any bearing on reality. No other market in the world works that way. A company wants to charge as much as it possibly can. A person in need of a service wants to pay a company as little as possible. There's sometimes a range where those two values overlap and that person can become a customer. It's all about perceived (not actual) value, which is heavily influenced by marketing and sales.

If you can't tie your actions directly to cost savings or revenue increases you're just blowing smoke up your manager's ass about value created anyway. It's all hand-wavey negotiation and negotiation is almost entirely based around leverage.
