I am proposing to sell by Shopify a book I am publishing. It worked well before. This time the book will be printed on-demand and I need to convert the order from the customer to an order and payment to the printer who will ship direct to the customer. Is there any smart way to do this other than manually transferring the data from incoming order to outgoing order? Strangely the print-on-demand business does not seem to have thought of 'drop-shipping'
