The Estimate Funnel shows how many quotes turned into jobs, and where the rest fell out.
The question it answers
Revenue is down. Is that because not enough people are asking, or because not enough of them are saying yes?
Those two feel identical from inside the business and have opposite fixes. More marketing solves the first and actively makes the second worse — you spend more to generate quotes you were already losing.
The funnel separates them, and it is the first place to look before changing anything about advertising.
Reading the shape
A funnel narrowing steadily is normal. A funnel that collapses at one point is the finding.
Wide at the top, narrow at the bottom — plenty of interest, few wins. A pricing, speed or trust problem. Buying more leads pours water into a bucket with a hole in it.
Narrow at the top, converting well — the work you get, you win. This is the better problem, and it is solved by visibility rather than by changing anything about how you sell.
Stalled in the middle — quotes going out and nothing coming back. Almost always follow-up. A meaningful share of quotes are lost to silence rather than to a competitor.
The number behind it
The funnel is close rate with the stages shown. One caution carries over: a very high close rate usually means underpricing, so a number above about ninety percent is worth checking against pricing adequacy before celebrating it.
