The Subcontractor's Bottom Line

The Subcontractor's Bottom Line: A Guide to Precision Bidding and Profit Protection

Being busy is not the same as being profitable.

The Subcontractor's Bottom Line is a practical guide for trade professionals who are tired of winning work, doing the job, paying everyone else, and wondering where the profit went. Whether you are a solo operator, a growing subcontractor, or a specialty contractor managing crews, this book helps you move from gut-feel estimating to a clear, repeatable system for protecting your margin.

Written for subcontractors in the real world of construction, this guide breaks down the numbers that many business owners overlook, including labor burden, overhead, markup, margin, production rates, change orders, cash flow, and job costing.

Inside, you'll learn how to:

Calculate your true cost of doing business
Build bids that cover labor, materials, overhead, and profit
Stop underpricing jobs just to stay busy
Protect your margin from scope creep and undocumented changes
Track job costs before small losses become major problems
Think less like a technician with tools and more like a CEO with a system

Profit should not be a lucky accident at the end of the job.

This book gives subcontractors the tools to bid with confidence, manage risk, and build a business that actually pays them for the work they perform.
