Overview

AI (Excel, Power BI, ChatGPT, Claude) helps analyze trends and build out scenarios (best/base/worst case) inside a cash-flow, sales or inventory forecast fast, but the model and its underlying assumptions stay entirely human-controlled — a client needs to be able to challenge and trust every number, not just accept a black box. Sold per unit or on retainer to SMEs and finance/operations teams.

Why it works

AI helps analyze historical trends and build out multiple scenarios inside a forecast much faster than doing it by hand. The model and its underlying assumptions stay entirely human-controlled, because a client needs to be able to challenge and trust every number, not just accept a black-box output.

How it makes money

Per deliverable + retainer

How to start

  1. Master Excel modeling — formulas, scenario tables, sensitivity analysis — to a genuinely advanced level.
  2. Pick a forecast type (cash flow, sales, inventory) to specialize your pitch and templates.
  3. Build one sample model to show the finished quality before any client conversation.
  4. Create multiple scenarios (best/base/worst case) as a standard part of every model.
  5. Find SMEs or finance/operations teams currently forecasting on gut feel or outdated spreadsheets.
  6. Sell the initial setup as a fixed-price project.
  7. Clean the client's historical data — this step usually takes longer than the modeling itself.
  8. Build the baseline forecast from that cleaned data.
  9. Add the scenario variations agreed on with the client.
  10. Explain every assumption in plain language so the client can challenge or trust the model.
  11. Update the model monthly as actuals come in, under a retainer.
