The Accountant Entrepreneur John Charman On The Numbers Business Owners REALLY Need To Know! | Ep 87

If you’re a business owner, entrepreneur, or founder who’s scaling but still “flying blind” with your finances, this episode is essential listening. MentorBusiness.com features heavily in this conversation because we get practical about knowing your numbers, not just filing them.

Lewis Haydon sits down with John Charman, an accountant turned entrepreneur, to expose the financial blind spots that stall good companies: cash flow crunches during growth, VAT shocks, thin margins masked by rising revenue, and the “rear-view mirror” problem of waiting on annual or quarterly accounts. This is not theory, it’s from the trenches, with simple explanations (like what a balance sheet actually tells you) and a CEO-level dashboard you can implement now.

They break down how to build a weekly financial rhythm, which numbers must live on your dashboard, and how to forecast so you sleep at night, because most businesses don’t fail for lack of sales; they fail for lack of cash.

Takeaways:

• Revenue ≠ profit: Why confusing turnover with take home keeps founders stuck.

• The CEO dashboard (not 50 KPIs): Net profit margin, cash flow forecast (90-day), client profitability, break-even point.

• Cash gap math: How scaling from £10k to £100k/month creates a £90k working capital hole and what to do about it.

• Forecast or panic: The weekly cash rhythm that lets you see problems 8 weeks ahead, not 8 hours before payroll.

• Balance sheet demystified: A plain-English way to read what you’d be left with if you stopped today.

• Tools help, ownership wins: Xero/QuickBooks make data visible your leadership makes it useful.

• Culture and numbers: Financial clarity drives calmer teams, better client service, and real competitive advantage.
