We place a lot of promotional orders via email. Many promotional vendors require us to provide net pricing. It would be a huge improvement if our purchasing department had an optional column to fill out net pricing and setups within the purchase order layout. We must use the notes section currently to document this information. On the back end of these transactions but still within the purchase order layout, a button to attach order and shipping acknowledgements, as well as receipts and vendor invoices would make life easier for billing as well as any research that our customer service team may have to do now or in the future.
