flatland desk — See what drives your numbers

Illustrative walkthrough using recorded calculations and fictional business
assumptions. Playback does not show processing time. This silent recording
shows the model view, an assumption edit and a downside scenario.

00:01 — See what drives revenue.
The model covers January through December 2026. Lines show how its assumptions
and calculated drivers feed into one another. Revenue is selected.

00:08 — Inspect the formula and its inputs.
The definition shows that revenue depends on customers and monthly revenue
per customer. These relationships remain visible in the model.

00:14 — Change one assumption.
Monthly revenue per customer changes from $249 to $259. This example holds
customer counts unchanged; it does not estimate how demand responds to price.

00:20 — See the effects.
The changed assumption is marked, along with the six calculated drivers
affected by it: revenue, gross profit, tools and infrastructure, operating
expenses, net income and cash.

00:27 — Follow the change through the model.
Revenue is selected again. Its relationships and updated monthly values can
be inspected together.

00:32 — Inspect the result over time.
Cash is selected. The monthly series shows the cumulative effect across the
year, with December cash at $170,233 after the change.

00:38 — Explore another scenario.
The downside_pricing scenario keeps its own revenue-per-customer assumption.
December cash is −$58,122. The assertion requiring nonnegative cash fails;
the model still solves and the failed assertion remains visible.

The walkthrough does not show an agent session, Windows installation,
sign-in, saving a file or opening an exported workbook in Excel.
