The five places sales funnels leak, in order of cost

Aggregate conversion tells you something is wrong. Stage-by-stage tells you where — and it is rarely where the team assumed.

When a funnel underperforms, the instinct is to look at the pages. More often the revenue is disappearing in the gaps between stages, where no single person's job description quite reaches.

These are the five, ordered by what they typically cost.

1. No follow-up rule after non-response

Someone enquires, you reply, they go quiet. What happens next is usually nothing, because nobody owns the moment after a conversation stops.

This is the largest recoverable leak in most funnels and the cheapest to fix. It needs no new demand, no new content and no new budget — only a written sequence and an owner.

A prospect going quiet is rarely a decision. It is a busy week.

2. Slow first response

Measure the time from enquiry arriving to a human replying. Not the automated acknowledgement — a human.

Nearly every team believes this is under an hour and finds it is over a day. Friday evening enquiries get handled Monday afternoon, by which point the prospect has spoken to two competitors.

The fix is routing and alerting with a named owner, not more staff.

Measure this before reading further. It is a five-minute query and it frequently reorders the entire priority list.

3. No qualification standard

Without a written definition of qualified, enquiries get graded by whoever picks them up, on whatever basis they favour that week.

The visible symptom is an argument about lead quality. The invisible cost is that every source comparison, every forecast and every routing rule downstream is built on an unstable measure.

4. An unowned proposal stage

Proposals sit. They sit because sending one is nobody's deadline, and because the person who ran the call is now running the next one.

Give the stage an owner, a target turnaround and a visible age in the CRM. Deals that age past a threshold should surface automatically rather than being remembered.

5. No post-purchase motion

Most funnels end at the sale, which treats the cheapest revenue in the business as somebody else's problem.

Onboarding quality drives renewal. Renewal drives expansion. Both are funnel stages with measurable transitions, and both are routinely unowned and unmeasured.

Where teams look, versus where the revenue goes

The right column is where most of the recoverable money sits.

Where teams usually look

  • Landing page design
  • Ad creative and targeting
  • Form field count
  • Headline wording
  • Traffic volume

Where the leaks usually are

  • No follow-up after non-response
  • Day-long first response times
  • Undefined qualification
  • Proposals with no owner
  • No onboarding or renewal motion

How to find yours

Count the volume entering and leaving each stage over a period long enough to matter for your cycle. The transition with the steepest unexplained drop is your answer.

Do this before changing anything. Optimising a stage that is not the constraint produces work, effort and no additional revenue — and it is the single most common way marketing budget is wasted.

Frequently asked questions

  • At the transitions between stages rather than within them, because the gap between two people's responsibilities is usually unowned. The most expensive is the absence of a follow-up rule after a prospect goes quiet.
