Episode notes
Open Book Management Equals Knowing The Score
- Open book management means sharing relevant financials so the team can make faster, more profitable decisions.
- Ellen emphasizes sales, profit, and cash (P&L and balance sheet) as the core score that operational changes should improve.
How A Handwritten Spreadsheet Raised Prices
- Ellen used a columnar pad to show her small plumbing team's true costs which justified large price increases.
- That early transparent math led her to raise rates dramatically and inspired her open book work.
Get To A Known Financial Position First
- Clean up your balance sheet and P&L to a Known Financial Position before sharing with the team.
- Go line‑by‑line with your bookkeeper or CPA so the first presentation isn't an unaudited 'hot mess'.
