Software is prevented from being distributed due to a human-caused error. A software distribution system includes a software distribution server that uses a campaign to manage an update of a function for an in-vehicle device of a vehicle and remotely distributes software based on the campaign, a terminal that executes input and output, and a software update device that is attached to the vehicle and configured to download the distributed software and install the software in the in-vehicle device. In the software distribution system, when the creation of the campaign is requested, statistical information of updated amounts of the software updated based on the most recent multiple campaigns in the target in-vehicle device for the requested campaign is compared with an updated amount of the software updated based on the requested campaign. When a predetermined requirement is satisfied, the requested campaign is not created and a predetermined alert is notified.
