In the pack: ChatGPT, Claude & Gemini Prompts to Write a Business Plan
Historical Performance Section for an Existing Business
Prompt
Summary of my last two or three years' accounts (revenue, gross profit, overheads, owner pay, net profit, by year): {{HISTORICAL_ACCOUNTS}}
Current year to date, and the same period last year: {{YEAR_TO_DATE}}
Anything unusual in those years (one-off costs, big customers lost or won): {{ONE_OFF_EVENTS}}
My forecast for next year, in summary: {{NEXT_YEAR_FORECAST}}
Produce:
1. A table of key figures and ratios by year: revenue growth, gross margin, overheads as a share of revenue, and net margin. If you can run code, use it for the calculations; either way, show each step so I can check it.
2. Adjusted profit with one-off items shown separately, each with its reason. Don't adjust anything I haven't explained.
3. A 200-word narrative of what happened and why, including the weak years.
4. A bridge from last year's actual results to next year's forecast: each change and its reason. Flag any jump the history doesn't support.
5. The questions a lender is likely to ask about these accounts.
Rules: use only my figures. Don't call a trend 'strong' or 'steady' unless the numbers show it. Not accounting advice; ask your accountant to confirm any adjustments.
