Considering this new risk reversal... Am I insane?

30 day money back guarantees were shocking at one time and so massively boosted conversion. These days everyone expects one and so while you'll suffer for not having it, no one's going to be surprised enough at this guarantee that it's really going to be a huge conversion boost.

That got me thinking to what the pain points with the normal guarantee are, namely that it often runs out before you've had a chance to try the product if you're busy and that you end up with another "to-do" if you want to cancel in writing and email saying that you want to cancel. Many people also feel they need to say why and are embarrased about it.

So what I'm considering is giving people the ability to cancel at any time with a few clicks from inside their account and get 100% of the money back. No time limits. No emails.

I've read that a bunch of testing showed that the longer a guarantee was the less people used it, thus the "anytime" part.

I'm sure that with this, I *would* get more cancelations, but it seems ballsy enough that if made a prominant feature would also raise sales, and providing my service (an online, software based service for a low-tech market) is also very cheap. We'd also ban credit card numbers that had been used on cancelled accounts to try and minimise scammers.

I know that the first answer would normally just be "Test it." which I will do, but if it tests poorly, I'll still be required to honour it to anyone who signed up during the test, so I wanted to do a sanity check here first.

The only real issue I can see is that when eventually the service closes down (hopefully not for years) that I really wouldn't want every customer who ever bought from us asking for their cash back. When we do eventually exit (which we have no plans to do, but happens to everyone some time) we will be releasing all the resources our customers would need to recreate our service, for themselves as a softener. Obviously anyone who had bought recently we'd refund without a second thought. I'd just rather not be refunding people from 10 years ago who hadn't used the service in 9...

So... could this work? Do you think it would be flaming, fireball of business death? I'd love to hear opinions (with reasons why)!
