What this panel is actually measuring
CAC payback is a cash-flow metric: how long it takes to recover the cost of acquiring a customer through profit or gross margin. Common payback models separate payback from topline revenue, and both warn that context matters.
The panel treats the funnel as four separate signals. A click is not a lead. A lead is not revenue. Revenue is not contribution margin. Attribution is not causation.
Reading each node
Cold Click
Measure the visit and preserve acquisition context.
EVENT: landing_page_view
Free Lead Magnet
Measure the permission exchange and asset delivery.
EVENT: lead_captured
Low-Ticket Tripwire
Measure cash collected, variable cost, refunds, and contribution.
EVENT: tripwire_purchase
High-Ticket Core Offer
Measure qualification, cash collected, retention, and expansion.
EVENT: core_offer_qualified
EVENT: tripwire_purchase
Same offer system. Different cash clock.
The tripwire is not a magic price point. It is a smaller paid outcome whose contribution is compared with allocated acquisition cost.

Ad platforms support transaction-specific conversion values. Analytics tools provide attribution paths show touchpoints, time to key event, revenue, and touchpoint count, with model-dependent credit. Use the platforms to observe the path, then reconcile it with finance data.
Common system faults
Gross-revenue substitution: a $39 payment is not $39 of contribution if fees, refunds, fulfillment, or support consume the difference.
Backend leakage: a later core sale can be valuable without being same-day liquidation.
Benchmark import: SaaS payback context does not automatically fit a service business.
Attribution overreach: a fractional credit allocation is a reporting choice, not causal proof.
Frequently asked
When is acquisition “free”?
Only when measured front-end contribution margin covers allocated acquisition cost for a defined cohort or window. The business still has costs.
What makes a tripwire legitimate?
It is a low-cost paid first step tied to the same problem as the core offer. The term describes intent and architecture, not a guaranteed conversion rate.
What is the key Day-1 event?
The purchase event with transaction-specific value and currency, reconciled against fees, refunds, fulfillment, and support costs.
Should the high-ticket offer appear immediately?
It can, but separating the first purchase and core offer makes front-end liquidation easier to audit.
What if the readout is negative?
Keep the label. Change the economics or accept the longer payback deliberately; do not rename the loss.
