Your Numbers Don't Match book cover by Gavin Somers

A clearer way to inspect mismatched numbers

Why numbers drift

The disconnect: see why technically correct dashboards and spreadsheets still disagree when definitions, timing, and source logic are not aligned.

The inspection path

Spot the gaps: a short, focused read for founders, CEOs, and operators who need to know where to look first across definitions, ownership, caveats, and source-to-report logic.

Stop scaling confusion

The next fix: know what to address before spending more on dashboards, automation, or AI over unreliable data foundations.
