I am an independent consultant with two direct sales companies. Your representative or consultant should be able to send you a receipt.
I work with many other independent consultants with other direct sales companies and so far, I have not heard of a company where a consultant can't send you a receipt. Company A sends the receipts for me. I send all receipts for orders made with me, via web or other contact, with Company B. I send receipts within 24 hours of notification of an order.
Contact the home office of the direct sales company giving them your consultant's name, the state, your name and the date of the purchase on the website. Give them the full website address where you ordered. They can find your order with that information.
