Frequently asked questions
Why do change orders matter so much?
Because small scope adds compound fast across a full year of jobs. A few missed extras on every project can erase a meaningful chunk of profit.
What is capture rate?
Capture rate is the percentage of scope additions you actually document, price, and bill instead of absorbing them.
Is this an exact accounting number?
No. It is a planning estimate meant to help you see the scale of leakage so you can tighten your process.
