How it works

Three steps to a number you trust.

  1. Open Rate Card. Enter your all-in hourly cost per role, wage plus payroll burden, not the rate you bill.
  2. Open Settings. Set your overhead percentage and the profit margin you want every job to earn.
  3. Open Job Quote. Name the job, enter the scope size, and pick a service tier.

Questions

Good to know.

Does it cover flat roofing?
Yes. Change the materials to your membrane system and keep the staging and disposal logic, those are the same on any roof.
How do I quote repairs rather than a full roof?
As a small job with a Standard tier. Repairs are mostly access and diagnosis, so make sure the lift or staging is priced in.
Does this work in Excel and Google Sheets?
Both. Google Sheets: File > Import, or open and make a copy. Excel 365: open it directly. No macros, no add-ons, nothing to install.
What is the service tier for?
It scales labor hours for work that is harder than routine. Standard is 1.0, Complex 1.15, Premium 1.30. Enter the hours a routine job would take and let the tier do the multiplying.
I'm not confident with spreadsheets. Will I manage?
Yes. The white cells are the only ones you touch. The Quick-Start Guide has your first real number on screen in about five minutes, and if you get stuck, message me.

One mispriced job costs more than this.

$49 once, and it's yours to keep. It pays for itself the first time it stops you underpricing a job or leaving margin on the table. No subscription, no login, just a file that does the maths.
