GP's company is (at least in their eyes) not interested in selling per se - quoting:

>> That means the sales person as they're working is not incentivized to sell as much as possible, they're incentivized to figure out the (potential) client's needs, and how we can best meet them, irrespective of what they end up paying.

I don't know what the name for that other thing is, but it's indeed distinct from "selling" that salespeople do, which boils down to begging, cajoling, tricking or coercing you to buy their shit, no matter how useless or downright harmful to you is, because that's what commissions combined with competition incentivize. Not surprisingly, the bottom-feeder telemarketing sweatshops are where this model is present in its purest form - extreme competition, frequent bonuses for top performers, and quick firing for not being a top performer.

If I have a choice, I never want to "buy" whatever someone's "selling" - I only want to do the whatever is the "buying" equivalent for the not-selling thing I don't have the name for.

It's not a B2B-specific phenomenon either. The B2C equivalent of those salespeople are car salesmen (which have meme status at this point), telemarketers, and those people doing the Amway model, trying to sell some Tupperware knockoffs[0] or barely working vacuum cleaners or whatnot at 3-10x inflated prices, making you feel like you had a good time instead of having just been scammed.

[0] - Ironically, Tupperware was also sold in this model, but it at least wasn't shit.
