Common questions
How does Build Margin handle PC and PS items?
Prime Cost and Provisional Sum items are first-class — track allowance, actual, and variation separately. Margin calculation applies correctly under HIA contract structures.
Can clients see margin information?
No, never. Margin is internal-only. Client Portal shows the agreed price and any approved variations. The internal Margin view shows where you are against budget.
What about architect collaboration?
Architects can be invited as collaborators on a project with read-only or comment access. They see plans, selections, and timeline — but not your margin or supplier pricing.
Does it handle long build timelines?
Yes. Build Margin is built for 12–24 month custom home builds. Phase Tracker, milestone payments, and long-running cash-flow projections are all designed for builds that don't finish in 12 weeks.
What about commercial fit-out work?
Build Margin's focus is residential, but custom commercial fit-outs (high-end retail, hospitality) work well. Industrial and large commercial isn't the right fit — look at Procore or Constructor for that.
