The embodiment of the invention provides a charge processing method and device. The method comprises the steps of: receiving a message sent by foreground equipment; decomposing the message into a message header, a message execution mode and a message execution content; distributing the message to a background server by analyzing the message header; and, calling an application in the background server according to the message execution mode and the message execution content. According to the embodiment of the invention, foreground and background data interaction and foreground and background calling of background applications can be realized through a middleware; therefore, foreground and background applications can be flexibly expanded through the middleware; charge configuration and testare realized mainly through the foreground, the background and the middleware; artificial participation is unnecessary; and thus, the charge configuration and verification efficiency can be increased.
