Plank packaging
An LVP quantity is a packaging problem after it is an area problem. Net square footage is only the first line. The order is whole cartons, and the trims are linear pieces that a square-foot waste percentage never buys.
Finish codes that share a color name can still have different plank sizes and stated carton coverage. Measure each code by room or zone. Do not add a glue-down plank and a floating plank into one area and split them later.
This site’s planning band for LVP is 5–10%, depending on layout. Pick the figure that matches the pattern and room shape, write it on the quantity sheet, and do not add a second percentage “just in case.” The extra coverage from rounding cartons is already extra material.
Reducers, end caps, stair nosings, and T-moldings follow the doorway and stair schedule. Record linear feet, then convert to the manufacturer’s piece length. A 7% area allowance does not produce a stair nosing.
This is arithmetic on an illustrative allowance, not a quote and not a required waste factor.

No. Waterproof wear surface does not tell you whether the slab needs moisture control or leveling. Those are separate scope lines, included only when the documents or a site reading require them.
On their own line, with the stair count and the nosing profile. Stair pieces are often a different SKU from the field carton.
