  1. 1

    Send the formula

    WhatsApp the formula, what it should do and what it does instead. A screenshot of a few rows helps; never send confidential data.

  2. 2

    Get the fix

    Within one working day you get a corrected formula and a plain-English note on why the old one broke. Free, no follow-up sales call.

  3. 3

    Choose whether it is published

    Only if you say yes, the fix appears below with names, sheet names and figures removed. Saying no changes nothing about the fix.

How we work

Six norms every FormulaSurge engagement runs on.

Not slogans. Operating rules. The same six on every dashboard build, audit, macro and model we ship.
