How to run a monthly reforecast with Claude using CFO Skill Stack
Install the Closed Loop CFO Skill Stack inside Claude, run the Q1 health check and build the reforecast in 5 minutes.
Most CFOs run the monthly reforecast as an open loop.
Q1 closes. The controller pulls actuals. FP&A rebuilds the model. You write the updated commentary. The deck goes to the board. The new forecast goes into the planning folder.
And three weeks later, Q2 closes and the team rebuilds the model from scratch.
That is the open loop most CFOs were trained on.
The closed loop is the opposite.
Every reforecast produces a record. Every record produces a pattern. Every pattern compounds into the next cycle. The CFO at reforecast 12 walks in measurably sharper than the CFO at reforecast 1.
Today I am going to walk you through the closed-loop reforecast end-to-end, using a real dataset. I am sharing the full Closed Loop CFO Skill Stack that runs it.
You get four files and they are self-improving.
Let me show you exactly how to install them, then walk through the reforecast.
Every CFO reading this newsletter must run this.
Let’s dive in.
