Build a compact scorecard around four numbers: customer acquisition cost, customer fulfillment cost, customer lifetime value, and churn. Then inspect the funnel to learn why those economics look the way they do. Acquisition cost is not controlled only by what the business spends on leads; it also falls when more of the existing leads progress and close. Fulfillment cost can be reduced through operational improvements, while greater customer value or retention can improve the other side of the equation. The scorecard's purpose is diagnosis, not reporting. Identify which lever—cost, conversion, value, or retention—offers the clearest improvement, change the underlying process, and calculate the metrics again. This focuses optimization on economic outcomes instead of indiscriminately cutting resources or buying more leads.
Origin
Russell Petty described the four business numbers he prioritizes and how Grow Mortgage used funnel data to select a conversion lever.
Core principles
- 01Track metrics that change economic decisions
- 02Acquisition cost depends on conversion as well as lead spend
- 03Fulfillment cost determines how efficiently value is delivered
- 04Lifetime value and churn reveal the durability of revenue
- 05Improve the weakest economic lever before buying more volume
How to run it
- 1
Measure acquisition
Calculate what the business spends to acquire each customer, including the effect of funnel conversion.
Pro tip Separate lead volume from the percentage that becomes customers.
- 2
Measure fulfillment
Calculate the resources and direct operating costs required to serve one customer.
Watch out Do not label a necessary delivery resource as acquisition cost.
- 3
Measure value and churn
Determine customer lifetime value and the rate at which customers leave or cease generating value.
- 4
Inspect the funnel
Compare lead, booking, attendance, and closing rates to locate where potential customers are lost.
Pro tip Look for a weak stage that can improve without increasing lead volume.
- 5
Pull one lever
Change the process to lower acquisition or fulfillment cost, increase conversion, raise customer value, or reduce churn.
Pro tip Choose the lever supported by the measured bottleneck.
Watch out Cutting costs blindly can damage fulfillment and customer value.
- 6
Recalculate economics
Measure the same four numbers after the intervention and retain the change only if the economics improve.
In the wild
Grow Mortgage had a strong booking rate but only a 31% show rate for booked referral calls. Instead of buying more leads, the team changed the pre-call process and raised attendance to 92%, moving roughly three times as many existing leads through the rest of the funnel.
→ Customer acquisition economics improved without an increase in lead volume.
Common mistakes
Tracking everything equally
A large dashboard can obscure the measures that actually explain customer economics and guide action.
Buying leads before fixing conversion
Adding volume to a leaky funnel can increase spend without addressing the stage that loses customers.
Is it for you?
Best for
It is best for businesses with a measurable funnel, identifiable fulfillment costs, and repeat or attributable customer value.
Not ideal for
It is not ideal for a pre-launch idea with no real customer or delivery data yet.
