| > This puts the business into the situation where they have an incentive If the payment is a one-time advance payment, I would imagine this disincentives the business to truly do their best, since they already have your money. I would think, idealistically, maybe the best model would be an advance payment but with a money-back guarantee of say half the payment if you don't find a match through them. Legally establishing that you don't find a match could be troublesome though, since the "couple" that actually liked each other could both claim they didn't match, get their 50% back, but you as a business would have no recourse if they got together and lived their lives happily ever after, behind your back. You don't have "rights" to their personal life together as a business. Unless of course it was a government-run dating service that had marriage, housing, and financial records of everyone. That might work. And for many reasons it's in the best interest of the government to get as many people married as possible. |
The one thing single-shot service-provider businesses (including professional human matchmakers) will do, though, is to calculate a quote for their service, corresponding to how much trouble they think your account is going to be for them. They don't usually bill more if it turns out to be even more of a challenge, but they do refine their quote process after each experience.
Though also, back to refunds: a refund guarantee doesn't need to be part of an explicit business-model, to be part of the effective business model. Dating sites charge people's credit cards. Large one-time charges from unknown companies you don't have an ongoing relationship with are exactly the type of thing that banks/credit-card companies are happy to do charge-backs for. Whether they offer refunds or not, the system will offer refunds for them — and kill their business by taking away its payment-processing if too many users ask for said refunds.
