Our project has been reviewd and following is the comment from USGBC
"Please provide documentation from manufacturers or suppliers that verifies product compliance with the specified sustainability criteria for a minimum of 20% of purchases by cost"

1) Do i have to provide the cut sheets of the products only or also the invoice scans for the purchased products?

2) We comply using 37% of the total purchase by cost.Do I have to give he total inventory and then show that we are using 37 % of products by cost?Is this detail required?
