Multi-level marketing computer network server

A server system for multi-level vending of any electronically transferable product (101) through a communications network (102) directly to a customer's computer (103). This server system (herein called a Sales Support Server (104)) integrates the collection of a payment (105) via the network (102) and the automatic distribution of the product (101) with the calculation (106) of commissions (107) using a multi-level marketing commission structure (108) and the distribution of commissions (107) and fees (109) via the network (102). The preferred configuration includes a client application (herein called a Sales App (110)) which can run as a plug-in to a network browser on the customer's computer (103) and which provides a purchase request (111) and registration data (112) to a Sales Support Server (104) and performs the installation (113) of the product (101) on the customer's computer (103). The Sales Support Server (104) acquires the payment (105), transfers the product (101), calculates (106) and pays the commissions (107), and adds seller registration information (112) to the multi-level sales database (114) for the product. The usefulness of this invention includes physical product distribution through a shipping and handling system.
