You already have figures, Excel sheets, financial assumptions and commercial estimates. Calc structures them into normalized, documented and comparable calculations.
Calc supports the quantified part of decisions with documented formulas for ROI, profitability, break-even, growth, commercial performance, forecasts and scenario deltas.
To compare campaign ROI, Calc tests budgets, conversion rates, margins, generated volumes and associated costs.
You stop debating scattered numbers and share a common basis for decision.
