Build vs. adapt: three-year financial model for e-commerce fundraising

[Sophia_A]

I'm seeking investment for my early-stage e-commerce startup and need to build a robust three-year financial model to present to potential angel investors. I've found several generic financial model templates online, but they don't adequately capture the nuances of my business, like customer acquisition cost trends, inventory turnover, and seasonality. For founders who have successfully raised capital, did you build your model from scratch or adapt an existing template? What specific sections or metrics did investors focus on most during your pitch? I'm particularly unsure how to model unit economics and scalability in a way that's both realistic and compelling. I need a framework that's detailed enough to be credible but not so complex it becomes opaque.

You’re right to pull templates apart. In my experience, if you want credible investor numbers for a lean e‑commerce startup, start from a scratch-built model but borrow a clean skeleton: a simple three-year revenue forecast, a unit-economics module, and a cash-flow/investment plan. Keep inputs in a separate “assumptions” sheet so you can stress-test without touching formulas. I usually build a modular model: channel economics, CAC curve, LTV assumptions, and a growth plan that links to a hiring plan and inventory plan.
