If it doesn't find you a leak worth more than the Build costs, you don't pay for it, and you keep the Plan.
That's the whole thing. Nothing to read up on underneath it. We can write that because of who it turns away. If your store's too small for us to find eight and a half grand of annual leak in it, you shouldn't be buying a build from us yet, and we'd rather find that out on our time than yours.
