EPOS add customer name instead of person making the order

When taking payment for Goods over a trade counter have the ability to Enter a Name (Customer Name) so they have a personal receipt and we have a record of what item they have purchased. Currently the username of the person signed into Storefeeder gives no permanent record and some businesses that purchase from the Trade counter require a better solution that us writing their company name on the receipt so they can put through their accounts and reclaim VAT
