Proof before promise

Evidence needs a chain of explanation

A revenue number alone does not tell a buyer what you can do. They need to understand the starting conditions, your contribution, the intervention, the time frame and the factors outside your control.

Build a case that can withstand questions

Record a baseline, an observable result and the source of the measurement. State whether the evidence is client-verified, independently measured or your own estimate. Ask permission before publishing identifiable client information.

Do not confuse confidence with causality

If several initiatives changed at once, do not attribute the entire improvement to your work. Explain your contribution and the uncertainty. A buyer who understands the limits of your evidence can make a better decision.

Reduce the size of the untested promise

When the evidence is incomplete, design an appropriately scoped diagnostic or pilot. Agree its decision criteria before starting. The purpose is to resolve a real uncertainty, not manufacture a miniature case study.

Your next move

For your strongest claim, identify the person, document or operating measure that supports it. If you cannot do that, improve the evidence or narrow the claim before putting it on a sales page.
