The research of billing schemes for computational resources is fundamental to information economy. Software agents that roam the Internet are consumers of resources. In this paper we first outline the surgeoncy of information economy as a result of computational resources being made available to the general public and their software agents. We propose a billing scheme for the usage of such resources using e-wallets and Internet dollars. The proposed billing scheme is applied to a community of mobile agents that live, and roam across a number of nodes, which provide the necessary resources and services used by these agents. An integrated service is charged at a dynamically computed rate at the end of a provider and agent negotiation phase. The paper also puts forward ways of achieving secure and reliable payments. The prototype implementation of a simulator is also discussed.
