We provided comprehensive long-term support for GOLF Partner USA's expansion into North America. Emphasizing strengths such as being one of the largest market shares, extensive inventory, and detailed assessment criteria, we constructed a Shopify store and integrated it with eBay. Our one-stop solution included photography, advertising operations, content strategy, and social media management. This approach enabled the opening of new customer channels through eBay, with a designed inventory linkage between eBay and the Shopify store, realizing a cross-platform presence.
