Inbound Platform Inbound Platform business induces consumption by tourists, thereby receiving a certain percentage of marketing commission based on the purchase volume of inbound travelers according to the contract to provide consumers with large domestic duty-free shops. Based on business experience and information on products and commissions accumulated through various networks, promotion details of duty-free shops, incentives by purchase performance, demand forecast for duty-free products, etc., it contributes to the development of the duty-free business by providing a safe transaction system and environment necessary to attract purchasing customers and enhance customer competitiveness by securing competitive commissions from duty-free shops to attract sub-tier travel agencies that attract customers while supporting for funds (advance payment) for smooth payback fee payment, maintenance of a credit environment that can guarantee safe fee receipt, and sharing of a reliable settlement system, etc.

The distribution of duty-free products refers to a business that directly launches and sells overseas luxury goods and domestic products at overseas duty-free shops or exports them to similar duty-free business sites online or offline, based on various know-how such as product information, consumer preferences and trends, purchase and distribution channels, and marketing strategies accumulated through the Inbound Platform business.

In order to become a world-class comprehensive travel agency, it is necessary to expand the business area beyond the Inbound Platform business through the combined management of Inbound and Outbound. Furthermore, it is also necessary to secure competitiveness through the establishment of a solid business infrastructure to ensure the successful entry and continuous development of new Inbound and Outbound businesses. As a result, the expansion of common and core business infrastructure for inbound and outbound businesses is required: first, secure stable flight seats and comfortable accommodations, second, organic cooperative relationships with domestic and overseas In-Outbound partners who can share win-win growth based on mutual trust.
