What it does

What Sauna does for fp&a analysts

01
Build the variance bridge
Sauna pulls actuals from QuickBooks against the budget in Google Sheets, builds the variance bridge by department and driver, and ranks the gaps that move the consolidated result.
02
Draft the board deck
It assembles the monthly results into a board deck in Google Slides — revenue, margin, headcount, cash — pulling the charts from the model and flagging the slides that need a manual figure.
03
Write the commentary
Sauna drafts the management commentary explaining each material variance with the driver behind it, ready for your edit before it goes to the CFO.
04
Refresh the forecast
It updates the rolling forecast with the latest actuals and the assumptions you give it, shows the changed drivers, and notes where the new run-rate diverges from plan.

Good to know

Questions, answered.

Will it change the forecast on its own?

No. It refreshes the model with actuals and the assumptions you provide and shows what changed. The forecast you stand behind is the one you approve.

Can I trust the variance numbers?

Actuals come straight from the ledger and the budget from your model, with the bridge math exposed cell by cell. Every variance ties back to a driver you can verify, not a black box.
