About This Model
A full operating model of a construction or contracting business. Monthly billings grow with backlog; direct costs and G&A set EBITDA; retention held back on each job is a working-capital drag on cash; and EBITDA sets an implied valuation. Built to show how thin construction margins survive the cash-flow whipsaw.

- •Defaults are illustrative benchmarks. The paid version ships in Excel so you can wire in your real chart of accounts.
- •For a model built entirely around your business — hiring waves, fundraising rounds, working capital — commission a bespoke engagement.
- •Educational decision-support tool — not financial, investment, tax, or legal advice.
