One of my clients has a technology that can save cost for a retail business. They did a pilot implementation at one retailer and have a lot of cost saving data as a result.
You can present this data to other potential clients (sanitised of course) in 2 ways. Approach one is the absolute number: we helped save $x,000 in costs. But this is hard to relate to for other retailers with different types of businesses. Better is to do it relatively: “we shaved 10% of the cost of item x.”, but it is still a bit generic, any startup with a cost saving technology has a sales pitch deck with these types of numbers. A credibility issue here.
Even better is to go into the nitty detail and highlight simple case examples of things that go wrong every day in a retail store, and how the solution helps to prevent it. It shows that you know what you are talking about, and lends instant credibility to your story.
At McKinsey we used to say: retail is detail.
