Short label used on the recipient block of the PDF, e.g. "Steel cladding & flashings."
Save the supplier first before adding a logo — the logo is stored against the supplier's record.
Attach this supplier's CSV price list. You'll be asked to map its columns to SketchUp attributes — this only happens once.
Extra CSVs from the same supplier — typically project-specific quotes that override the main catalogue. Each one has its own column mapping, so the layouts don't have to match.
