In many ways it’s akin to the reason why SLAs don’t mean shit when they’re business to business. Anybody who breaks even in using a tool doesn’t stay in business for long. They use a tool because the tool -all of the tools - plus the labor costs them a dollar for every 10 they can gross. Your $1000 a month service can hold up or straight up lose $50,000 in revenue, so don’t be surprised if I’m not that happy about you offering to cut us a check for $250 when your stuff shit the bed two days before a hard deadline.

We want the money back guarantee because we think the specter of you making no money will motivate you not to fuck us over. Your guarantees mean next to nothing, and the manpower involved in getting and cashing that check might eat most of it up anyway.
