Selected Cross-Border Experience
Practical experience supporting Korean companies and their U.S. operations.
K-Beauty U.S. Market Entry
We advised a Korean beauty company entering the U.S. through e-commerce and retail channels on its U.S. entity structure. Our work separated revenue and expenses by sales channel and supported accounting and tax registrations for local sales.
U.S. Operations for a Korean Technology Company
We organized accounting categories so a Korean IT company’s U.S. subsidiary could track costs by R&D and engineering project. We also developed intercompany transaction procedures and assisted with U.S. GAAP and K-IFRS reporting.
U.S. Expansion for a Korean Franchise Brand
For a Korean brand preparing to franchise in the U.S., we reviewed royalty settlement procedures and franchise fee revenue recognition. Our work included financial reporting for FDD preparation and accounting support for franchise operations.
U.S. Subsidiary Reporting to Korean Headquarters
We reflected U.S. GAAP-to-K-IFRS differences in the U.S. subsidiary’s monthly closing data for consolidation by its Korean headquarters. We reconciled intercompany balances and coordinated with transfer pricing reviews to prepare the headquarters reporting package.
