A management system is implemented by one or more information processing apparatuses connected via a network to one or more execution apparatuses that execute processes constituting a process flow. The management system includes a first registration unit that registers, in a storage unit, an information structure that is generated when the process flow is executed and that is used to store at least one of billing information and an execution result of each of the processes in the process flow. The system also includes a receiving unit that receives at least one of the billing information and the execution result from each of the execution apparatuses. Further, the system includes a second registration unit that registers at least one of the billing information and the execution result received by the receiving unit in the information structure.
