Your inspection book
Every number is an input — plug in your own. The math updates as you type; nothing is submitted anywhere.
The leak is the quoting lag. When a deficiency is photographed on site and the quote goes out the same day, the quoted percentage stops being a coin flip. That deficiency-to-quote flow is the core of Essential.
Book a 15-minute demoHow the math works
Annual inspections = techs × inspections per tech per week × 50 working weeks. Inspection revenue multiplies that by your average invoice. Deficiency revenue takes the inspections that find something, applies your quoted percentage and win rate, and multiplies by the average repair invoice. The "left unquoted" figure runs the same math on the deficiencies that never got a quote: findings your techs documented, at your own win rate and ticket size. Admin cost is your per-inspection office minutes times the annual volume times your hourly cost.
One default comes from real data: the 34% deficiency rate is the observed share of reports with at least one finding across an anonymized sample of 8,786 inspections run through Essential. Everything else is your own assumptions, multiplied out. The number most shops underestimate is the quoted percentage: paper inspection reports make quoting a separate office task that happens days later or never, which is how documented findings quietly expire.
Common questions
Is 34% a realistic deficiency rate?
It's the observed rate across inspection reports submitted through Essential: of 8,786 reports in an anonymized sample, 34% recorded at least one deficiency, with a median of 3 findings per deficient report. Your mix matters — extinguisher routes trend lower per unit, sprinkler and alarm work on older commercial stock runs higher — so use your own last quarter if you have it: deficiencies found ÷ inspections completed.
Why 50 weeks instead of 52?
Holidays, truck time, and training eat about two weeks of route capacity a year for most shops. Change the inputs if your calendar runs differently.
Where does the money actually leak?
Two places this calculator makes visible: deficiencies that never become quotes, and office hours spent retyping what the tech already wrote in the field. Both are workflow problems, not sales problems.
