🚨 Below-cost selling detected: Smith Supplies Corp. — the product's largest customer — bought 897 of the 976 units sold in the last 6 months at an average $157.95, which is $8.64 below the $166.59 unit cost: roughly −$7,750 of negative margin. The blended 6.9% product margin is being carried entirely by list-price buyers (Camimbo, Rhynyx, Pixoboo at $450–500). Before chasing cost wedges, fix this price.
💡 Where the cost lives: only $62.54 (37.5%) is purchased material — $104.06 is value-add across 5 build stages. Largest part: the $19 solar panel. Hot spot: FRM200 frame value-add trending +10.1% (+$4.88/unit). At ~1,950 units/yr, that's $9,528/yr — and it cuts the already-thin margin from 6.9% to 4.2%.
