Earlier quoted context omitted.
I have seen companies that would refuse to serve customers that had not been growing as expected. Literally. Bogles my mind.
Why? Margins matter, not just dollars alone. If you spend 75 cents to earn a dollar on one customer and can spend 25 cents to earn a dollar on another customer, you'd be dumb not to take customer 2.
It seems nobody can believe your assertion that a company would deliberately fire a profitable customer by quoting an x12 contract increase. There's no point asking me to talk to people in my business. You're going to have to point to publicly accessible resources.
