Margin Protection Starts Before the Job Starts

For contractors, margin protection is not something that happens at the end of a project. It starts much earlier.
Margin is affected by the way work is qualified, priced, sold, handed off, managed, billed, and measured. By the time a project is halfway complete, many of the decisions that determine profitability have already been made.
That is why contractors need to look at margin protection as an operating discipline, not just a financial result.
A strong margin protection process should help the company answer several important questions:
Are we pursuing the right work?
Are we protecting margin during estimating and pricing?
Are scope, exclusions, assumptions, and risks clearly understood before the job starts?
Is the project properly handed off from sales and estimating to operations?
Are change orders being captured and billed in a timely manner?
Are job costs, WIP, billing, and cash flow being reviewed consistently?
Do project managers understand where the margin is and where it can be lost?
Too often, contractors discover margin erosion after the damage has already been done.
The better approach is to create control points throughout the life of the project — from opportunity qualification to project closeout.
Margin protection is not just about making more money.
It is about creating better discipline, clearer communication, stronger accountability, and a more reliable way to run the business.
At Shapcott Lauber, we help owner-led construction companies identify where margin is being protected, where it is being lost, and what operating disciplines need to be strengthened.
The key question is simple:
Where is your margin being protected, and where is it quietly slipping away?
