A seller's computer system, accessible by a customer's computer over the internet for ordering products, includes a product information unit, a purchase transaction information entry and verification unit; a transaction information storage unit, a transaction code generator, a purchase order generator, a transaction code interpreter and payment processor, and a product purchase control unit. The product information is accessed by the customer's computer to enable the customer to view the product information. Upon receipt of a purchase request from the customer, the seller's computer requests and receives transaction information including information of the product or products to be purchased, customer information, and payment information. When payment is to be made by a payment document or a negotiable instrument such as check, money order, cash or signed credit card authorization, the seller's computer generates and sends to the customer's computer a purchase order including a machine readable transaction code which identifies a stored record in the seller's computer containing the transaction information. Upon receipt of the payment document with a copy of the purchase order, a code reader reads the machine readable transaction code, and the transaction code interpreter and payment processor recalls the corresponding stored record for verification of payment prior to authorizing the sale of the product or products.
