A method for operating a commissioned e-commerce service provider provides services to businesses on a computerized network such as the Internet in exchange for a small commission on the commercial transactions generated using those services. Unlike most ISPs that provide services to individuals and businesses, the commissioned e-commerce service provider preferably provides Internet services for businesses operating web sites or other application that generate e-commerce transactions for the business. Instead of paying a monthly fee for the Internet services required to host a web site or operate and e-commerce site, the business contracts with the commissioned e-commerce service provider to provide these services based on receiving a percentage commission of the commercial transactions generated using these services. Preferably, the commission percentage is tiered in accordance with the amount of traffic at the site to provide a nominal level of service at a lower commission rate, yet allow for an exceptional volume of traffic to be accommodated by the site at a higher commission rate without having the site fail or the service become overwhelmed.
