Inputs
Spend, leads, qualified leads, customers, gross profit, cycle length, capacity and attribution confidence for each channel.
APIS LAB / Tool
Channel portfolio
Budget decisions become stronger when the model includes evidence quality, capacity and downstream economics, not just reported ROAS.
How to read the result
Workspace
Enter the inputs and the model will show both the result and its reliability
| Channel | Spend | Leads | Qualified | Customers | Gross profit | Cycle, days | Capacity 1–5 | Attribution confidence, % |
|---|
The result will appear here.
Check the units, periods and definitions before running the calculation. Weak input data produces weak conclusions.
Method
A tool is useful only when you can see what the conclusion rests on
The interface is only the front layer. The real value is the ability to inspect the inputs, understand how the output is calculated, recognise what the model cannot know and translate the result into a management action.
Calculation method
The model calculates CAC, qualification quality, gross-profit return, net contribution and an evidence-adjusted comparison, then suggests a management action.
Limitations
Attribution confidence is entered by the user and does not replace causal measurement. Capacity and saturation effects are simplified, and cross-channel influence is not modelled.
Management output
A portfolio decision that distinguishes genuine scale candidates from channels that only look good because measurement or quality is weak.
APIS LAB principle
A result is complete not when a chart appears, but when it becomes clear which decision follows, which assumptions remain disputed and what next evidence could change the conclusion.
