Your agreement book is the part buyers pay extra for.

When a trades business sells, the maintenance-agreement book is the most documented value driver in the deal: advisors report 2–3x the book’s annual recurring value on top of the base multiple. Run your numbers — and see the two benchmarks buyers check before they believe the count.

Sources — and the calibration most calculators omit

The 2–3x-ARR range and the service-revenue multiple effect come from published trades-M&A advisory analyses; the 1,000–1,500-per-$1M density and 85%+ renewal benchmarks from Gary Elekes (EGIA) in Contractor magazine. The calibration: the most HVAC-specific business broker reports buyers always ask for the count but pay through earnings and retention — so treat the range as directional, not a quote. This is arithmetic on published benchmarks, not a valuation of your business.

We build the book — and prove its quality monthly

Morthn runs memberships end to end: enrollment, pre-season visit scheduling, dues chasing, and the exact metrics a buyer will one day audit — agreement count, density per $1M, renewal rate, and visits owed vs delivered. The book narrative lands in your monthly report, sourced the same way this page is.
