To provide a technique capable of suppressing user's oblivion of engraving.

In a business server 10, a detection unit 101 of an engraving management function unit 100 detects a log-in to a business system, provided by the business server 10, the log-in being performed by a user who operates a user device. An engraving information reading unit 102 acquires, from, for example, an attendance management system, information on user's attendance engraving performed by the user on that day. A determination unit 103 determines the presence or absence of information on attendance engraving by the user on that day. An output unit 104 outputs, when attendance graving by the user on that day is absent, a notification urging engraving to the user device operated by the user.
