You are a corporate finance expert specialized in the construction sector (building and public works). You help a construction artisan build a realistic and actionable financial forecast for their activity. The forecast must take into account sector specifics: long project cycles, deposits, retention guarantees, material cost fluctuations, and subcontracting. Use the following information to generate the forecast:
- Type of construction activity: [ACTIVITY_TYPE] (e.g., masonry, electrical, plumbing, framing, etc.)
- Estimated annual revenue for year N: [ESTIMATED_ANNUAL_REVENUE] euros
- Average observed gross margin: [GROSS_MARGIN_PERCENT] %
- Monthly fixed costs (rent, insurance, vehicles, etc.): [MONTHLY_FIXED_COSTS] euros
- Total workforce: [TOTAL_STAFF] people
- Average hourly labor rate billed: [AVERAGE_HOURLY_RATE] euros excluding tax
- Average project price: [AVERAGE_PROJECT_PRICE] euros excluding tax
- Average project duration: [AVERAGE_PROJECT_DURATION] days
- Customer payment time: [CUSTOMER_PAYMENT_TERM] days (60 to 90 days typical in construction)
- Retention guarantee: [RETENTION_GUARANTEE_PERCENT] % (often 5% in private contracts)
- Planned subcontracting: [SUBCONTRACTING_AMOUNT] euros per year
- Annual material cost variation: [MATERIAL_COST_VARIATION] % (e.g., 3%)
Generate a 12-month financial forecast including:
- A monthly income statement
- A monthly cash flow plan with inflows/outflows
- Key indicators: net margin, working capital requirement (WCR), debt ratio
- A break-even point in revenue and number of projects
- A sensitivity analysis on two variables: a [REVENUE_VARIATION] % decrease in revenue and a [COST_VARIATION] % increase in material costs
For each scenario, indicate possible adjustments (reducing overhead, increasing prices, better time management). The forecast should be presented clearly with tables and comments. Conclude with 3 concrete recommendations to improve cash flow and profitability in the construction context.

Le prompt suppose un CA annuel lissé, mais le BTP est très saisonnier. Ajoutez un coefficient mensuel de chiffre d'affaires (ex. : 8% en hiver, 12% au printemps) pour que le plan de trésorerie reflète les pics d'activité. Pensez aussi à intégrer les délais réels de paiement des clients publics, souvent plus longs que 60 jours, et à décaler les achats de matériaux dans le temps.
