Overdose's Shopify Plus page offers an outcome-based partnership measured on "Revenue vs forecast, CAC, AOV, repeat rate", and says that when the agency falls short, "That is our cost". It is a strong offer, but the proof does not match it: 38 of the 77 case studies on /work show a results figure, and 39 (including Petbarn and the Zoe & Morgan conversion review) describe the work with no outcome at all. Some of the figures that are shown, like the Adairs SEO results, compare 2022 with 2024.

Why it works
Give every case study a results line in the same format: one or two measured outcomes, the period compared and the source (for example "+18% repeat rate, six months after launch vs the six months before, Shopify analytics"). Where a client will not share figures, use delivery outcomes (weeks to launch, systems connected, tickets cut). Add a results filter on /work and a "results we were paid on" strip on the Shopify page. Refresh the older figures with the latest year.
A buyer comparing agencies that all say "AI-first" picks the one that shows outcomes. An outcome-based fee is believable only when the case studies show outcomes as well.
