How to build a finance function in an EOS company

Guide·By Scott Engler·Updated August 2026

Build a finance function for an EOS company in a clear sequence: get a reliable monthly close, then trustworthy Scorecard measurables, then reporting tied to Rocks, then forecasting. Each step depends on the one before it.

In short

Building a finance function for an EOS company isn't about hiring the most senior person you can afford — it's about putting the right layers in place in the right order. Done in sequence, each step makes the next possible.

Step 1 — A reliable monthly close

Get the books closing on a set date every month, reconciled and trustworthy. This is the foundation; nothing above it is stable until it's solid. See what a good close looks like.

Step 2 — Trustworthy Scorecard measurables

With a reliable close, choose the few financial numbers that reflect real health and produce them consistently. Start small — a handful of trusted numbers beats a board full of disputed ones. See which metrics belong on your Scorecard.

Step 3 — Reporting tied to your Rocks

Structure monthly and quarterly financial reporting around your Rocks and V/TO, so the numbers connect to what you're actually trying to build.

Step 4 — Forecasting and cash visibility

Add a 13-week cash forecast and simple forward models, so the leadership team plans from real numbers instead of hope.

You can't skip steps. Trustworthy measurables need a reliable close; forecasting needs trustworthy measurables. Build the foundation first, then layer up.

Who builds it

This is controller-level work. Most growing EOS companies fill this with a controller — full-time, fractional, or outsourced — who owns the close, reporting, and measurables. Where you are in this build maps to the Finance Seat Maturity Model.
