Aries, the second source above, argues that an audit under $2,000 is “diagnostic theater” and that a fee credited back against later work was never really an audit.2 I think that’s a way to justify charging a lot for a short engagement, and it isn’t why this one is priced where it is.
The real reason it costs anything is that it protects my time. Before it existed I kept ending up in two or three follow-up calls with the same prospect, and by the end of those I had handed over a playbook for fixing the problem themselves, for free. I don’t mind somebody taking that and building it on their own, and honestly if that’s what you want then this is the cheapest way to get it. But I do have to scope what I commit to when an engagement isn’t going to become a long-term one, and a flat fee with a defined end is how I do that.
The credit exists so you’re not paying twice for the same two weeks if you do carry on. If you don’t, you keep the inventory, the scorecard and the 6 month plan, and your team runs the plan without me.
