Frequently asked questions
Why three material families only?
Keeps the page honest. Add more categories later once we collect defensible heuristics.
Sheet size changes waste?
Yes in real life. Use the extra percent field when running 54" board or high scrap layouts.
Job costing integration?
Copy the order quantity into ServiceTitan, Jobber or your lumber yard app manually.
Metric?
