I think it gets more nebulous. For example, does he only get paid if the tax returns are accepted by the government? If they aren't, he's still put in the work. This becomes an extremely slippery slope. A better example is probably retail. In the US at least, places like Walmart and Amazon allow for returns, but they usually just throw it out. That's gotta be built into the price. Meaning, the cheapy no returns accepted online stores are cheaper because the cost for the purchaser isn't tied to satisfaction.

Your accountant has to build in margin that you pay for for clients who stiff him on the bill or who he has to take to court to argue he did the service as described in the contract. If you didn't hold that threshold over his head, he would be able to charge less. Would he? Maybe not, I don't know the guy, but he could.

Understood. So, a better way is to keep him on a retainer? Or let Amazon or Cheaper store do a cost-plus model?

I think that is the core of the argument. It is the risk-sharing between buyer and seller. If sold on outcomes, seller carries all risk. If sold on work-put-in, buyer carries all risk.

Add to that, in some scenarios, outcomes themselves are fuzzy.

Cost plus I'm not sure on. Maybe if your work was in small enough chunks. But if, did example, just generating one response is too expensive, there's no plus, it's just somebody paid $ for some bits in GPU memory and that's likely not useful to anyone.

Yes exactly. Your second paragraph hits the nail on the head. And I'm sure you agree that the AI companies aren't going to take on more risk for free.
