Every home improvement operation has a cancel rate. Most treat it as a cost of doing business, an unfortunate but unpredictable percentage of signed contracts that unwind before installation. They manage it by accepting it. They report it as a single number. They do not read it as the diagnostic it is.

A cancel rate is not a measurement of customer behavior. Why Home Improvement Contractors Have a Cancellation Problem No One Is Talking About established why the industry tends to accept it rather than diagnose it. It is a measurement of system failure, and the system failure it is measuring depends entirely on when the cancellation occurs. The timing is the data. Most operators discard it.


What Post-Sale Attrition Actually Measures

Post-sale attrition is the third constraint type in the Revenue Constraint Model. It is also the most deceptive. Funnel Compression shows up in low appointment volume. Rep Variance shows up in a wide close rate distribution. Post-Sale Attrition shows up in none of the numbers operators typically watch closely. The pipeline looks healthy. The signed revenue figure looks strong. And then, quietly, contracts start coming off the books.

The property that makes post-sale attrition distinctive is this: it is the only constraint that allows every upstream metric to look clean while installed revenue deteriorates. Set rates are holding. Run rates are solid. Close rates are in range. The floor is producing signed contracts at benchmark. And the operation is still installing fewer jobs than the pipeline suggests it should, because somewhere between signature and installation, the contracts are disappearing.

The marketing dollar that funded those leads was spent the moment they entered the funnel. The setter time that converted them to appointments was consumed. The rep's commission was earned at signing, in many compensation structures, before the install ever occurs. By the time the cancellation is recorded, every upstream cost has already been incurred. The revenue is the only thing that didn't arrive.
