The invention discloses a virtual object renewal method and device. The virtual object renewal method comprises the steps of acquiring a user identification set and virtual object information corresponding to each piece of user identification in the user identification set, wherein the virtual object information comprises object identification and deadline of at least one virtual object; determining a target virtual object corresponding to target user identification from the at least one virtual object according to each deadline; determining a target virtual bill from a stored virtual bill library according to the object identification of the target virtual object and target user identification; acquiring a virtual bill to be exchanged of the target virtual object according to the target virtual bill; and performing renewal on the target virtual object according to the target user identification and the virtual bill to be exchanged. The virtual object renewal method and device can well realize a cross-platform asynchronous renewal operation, interruption of subscribed services is avoided, and the method is simple.
