What Sales Funnel does
Sales Funnel structures conversion from awareness through qualification, proposal, onboarding and retention.
A sales funnel describes the stages through which a target customer moves from initial awareness to a qualified decision, implementation and continued use. It helps strategy teams connect positioning and pricing to real customer actions.
The funnel is a planning model, not a claim that every journey is linear. Define entry and exit conditions, evidence, friction and ownership for each stage, then test where and why progression breaks down.
This is a go-to-market planning surface rather than a CRM replacement. It connects positioning and pricing choices to stage-specific evidence, friction, ownership and experiments.[1][2]
Each stage needs a customer action, evidence and an owner for resolving friction.

Do not just count volume. Define the observable customer action and evidence at each stage.

Understand the method
The parts in plain language
Stage and customer action
Name stages using observable customer progress rather than internal sales activity alone.
Illustrative example
The customer confirms a relevant problem and agrees the next evidence needed for evaluation.
Qualification and evidence
Define what makes an opportunity suitable and what evidence supports movement to the next stage.
Illustrative example
A target site has sufficient energy cost, data access and a named operational sponsor.
Friction and conversion
Record barriers, messages, experiments and conversion assumptions. Segment the funnel when buying processes differ.
Illustrative example
Security review, not product interest, may be the dominant source of delay for enterprise customers.
When to use it
- When a strategy needs a practical route to repeatable demand.
- After target, positioning and pricing hypotheses have been defined.
A practical workflow
- 1
Define the segment, offer and funnel stages.
- 2
State the customer action, qualification rule and evidence for each stage.
- 3
Record friction, messages, owners, status and conversion assumptions.
- 4
Create experiments and roadmap actions for blocked stages.
Fictional worked example
Example: selling an energy service
This example is illustrative rather than a reported case. A team designs the route from initial interest to a repeatable multi-site contract.
Observation:Many leads lack enough energy spend to justify the service.
Implication:Add an early suitability check.
Observation:Finance needs a credible baseline and sensitivity range.
Implication:Standardise the business-case evidence.
Observation:Successful pilots do not automatically reach other sites.
Implication:Add a multi-site adoption and procurement stage.
From analysis to decision
How to interpret the result
- 1Use customer behaviour to define stage movement.
- 2Compare conversion and friction by segment.
- 3Turn weak stages into owned experiments and roadmap actions.

What a useful output looks like
Common pitfalls
- A generic funnel can hide major differences between segments.
- Do not treat movement through stages as linear when the evidence says otherwise.
