A system enables tender of payment manually (e.g., cash, check, etc.) for transactions conducted over a network (e.g., the Internet). The system includes one or more computer systems each located at a corresponding agent site, one or more merchant systems and a server computer system in communication with the agent and merchant systems. The server system accesses the appropriate merchant network or web site in response to transaction selection information received from the agent system, and translates those web pages for transmission to the agent system. The server computer system further receives the required transaction information from the agent system and processes the transaction information for transference to the particular merchant web site. In addition, the server system enters credit card information of a provider of the transaction service within the transaction payment information for transference to the merchant system in order to tender payment for the network transaction.
