I am unfortunately dealing with documentation that others gathered, and I am now trying to make it work. I have an invoice for FSC wood that was used for our doors. Although the invoice shows line items, there is no cost per line item nor FSC identification per line. There is an FSC Mix stamp and a total cost at the bottom. This obviously doesn't meet the standard format that LEED requires. The invoice is a year old (and paid) and the company is saying that they aren't able to alter and/or reprint the invoice. Any alternative? Could I get a letter from the company to suppliment the invoice, breaking down the info on the invoice the way LEED requires? Has anybody tried this, and what success have you had? Help!
