How we calculated this
Formula → rules → price lookup
1. Formula evaluation — Each BOM quantity is derived from the template's formula and your chosen dimensions (area, length, etc).
2. Rules — No adjustment rules applied to this build.
3. Price lookup — Cheapest current offer per item across tracked suppliers. Prices are preliminary until the Price Aggregation release.
FAQ
How accurate are these prices?
They are preliminary — generated by a stub model until the Price Aggregation release wires real supplier feeds. Treat them as a ballpark, not a quote.
Can I customize dimensions?
Yes — open the template and apply it to a project. You'll get a form for the declared parameters (area, length, etc) and the BOM recalculates automatically.
How is the waste factor applied?
Where a master has authored a waste-factor rule for a material, we add a percentage buffer (typically 10–20%) on top of the formula quantity. The exact rule and value are shown next to the affected row.
