Why planners use it

Makes pitch adjustment visible.
Separates material units from accessories and cost.
Keeps calm disclaimers close to the estimate.

What to review before ordering

All quantities are planning estimates. Review final dimensions, product coverage, waste, supplier packaging, and field conditions before ordering.
Cost outputs use the prices you enter and are not quotes, bids, invoices, or procurement instructions.
