Cost lever
Per-window installed price
A quote's total divided by its window count — the only number that compares apples-to-apples across bids.
What it means for you
Two “$20,000” quotes aren't equal if one covers 8 windows and the other 14. Normalize to per-window, pin the same spec on all bidders, and the wildly different totals finally line up.
Where you'll see it
You have to compute it — most quotes are a single project total.
