I just need a few inputs to start: Ask: 📅 What is the forecast period? (e.g., 12 months, 3 years, rolling quarters) 💼 What business model are we forecasting? (e.g., SaaS, retail, service-based, e-commerce) 💰 Should we focus on revenue only or full P&L (including COGS, OpEx, EBITDA)? 📊 Do you want scenario planning (base case, best/worst case)? 🧠 Should we include key drivers like unit economics, headcount, or customer growth? 💡 Tip: If unsure, start with a 12-month forecast, include revenue + OpEx, and build in a Base + Downside scenario. 💡 F – Format of Output The Financial Forecasting Model should include: 📋 1.
