Technology Forecasting Model for Customer Growth

I need a forward-looking financial model built in Excel or Google Sheets that zeroes in on customer growth for a tech-sector business. The core objective is to translate acquisition, churn, and retention assumptions into monthly and annual forecasts that I can plug directly into strategic planning discussions.

Please structure the workbook so assumptions, calculations, and outputs are clearly separated. A dynamic dashboard or summary sheet that visualises customer cohorts, net additions, and cumulative users will be very helpful. Sensitivity toggles for best-, base-, and worst-case scenarios must be included, allowing me to adjust inputs such as marketing spend or conversion rates and instantly see the impact on customer counts.

Accuracy, clean formulas (no hard-coding in calculation cells), and professional formatting are essential. I will consider the model complete when it:

• Lets me update headline assumptions from one control panel
• Recalculates 36-month customer forecasts instantly without broken links
• Presents results in charts I can drop into a pitch deck

If you have previous examples of forecasting models for SaaS or other tech businesses, feel free to mention them when you send the file.
