Terms of Use

Last updated August 20, 2026

Plain terms for using this site. Using it means you're okay with them.

The part that actually matters: the bid calculator and the articles are estimates and general information. They are not a bid, not an engineering opinion, and not a substitute for pricing your own job. Check every number against your own costs before you put it in front of a customer.

Who you're dealing with

This site is operated by The Contractor Playbook, a sole proprietorship, contactable at hello@contractorplaybookpro.com.

The calculator

The bid calculator produces estimates based on national averages. Swell factors, truck capacities, equipment rates, clearing costs and septic component prices vary enormously by region, by soil, by season, and by who you buy from.

  • It is a sanity check, not a bid.
  • Every number it produces should be verified against your own costs and your local rates.
  • It performs no site assessment, no soil analysis, and no engineering. Where a job requires a geotechnical report, a survey, a permit or a licensed engineer, get one.
  • I'm not responsible for a job that lost money, a bid that came in wrong, or work performed based on numbers from this tool.

It runs entirely in your browser. Nothing you type into it is transmitted or stored.

The articles

Everything here is general business information for contractors, written from experience. It is not legal, tax, accounting, insurance or engineering advice, and reading it doesn't make me your lawyer or your accountant. Rules on worker classification, licensing, liens, insurance and taxes differ by state and change over time. Before you act on anything here that carries real consequences, talk to a professional who knows your situation and your jurisdiction.

Affiliate links

Some outbound links earn me a commission. It costs you nothing extra and doesn't change what I recommend. See the affiliate disclosure.

Your content

If you email me or fill in a form, you keep ownership of what you send. You're giving me permission to use it to respond to you. If I ever want to quote you publicly, I'll ask first.

My content

The articles, the calculator and the downloads are mine. You're welcome to read them, use them in your own business, print them, and put the checklist in your truck. Don't republish them as your own or resell them.

Website services

If you hire me to build a website, that work is governed by the separate written agreement we sign — not by this page. Where the two disagree, the signed agreement wins.

Availability

I try to keep the site up and the information current. I don't promise either. Things go offline and information goes stale.

Liability

To the extent the law allows, I'm not liable for indirect or consequential losses arising from use of this site or the calculator. Some states don't allow certain limitations, in which case they don't apply to you.

Governing law

These terms are governed by the laws of the State of Tennessee, without regard to conflict of law rules.

Changes

These terms may change. The current version is always the one on this page, with its date at the top.
