The wood invoices that I have show a separate line item for tax/fuel charge/freight charges, etc. and I was unclear how to include this in the documentation.
Do I take the total of the entire invoice as the cost, then calculate out the amount of wood (separate from the extra fees) as the % of new wood, and then calculate the % of FSC from all the wood?
OR do I add up the line items of wood and use that as the total cost, list that it as 100% wood, and then calculate the amount of FSC wood from all the wood?
