E-commerce AI Operations Team: A Practical Guide — Automating Month-End Close Tasks for Settlements, Returns, Inventory, and Customer Service on Naver Smart Store, Coupang, and Cafe24 with Claude Cowork

Turn half a day of month-end closing into 30 minutes of uploading files and checking results. Give Claude Cowork 16 sample channel files in Smart Store, Coupang, and Cafe24 formats, and build an integrated order sheet → settlement reconciliation (orders ↔ settlements ↔ bank statements, with zero unexplained discrepancies) → returns P&L → inventory and purchase orders → pending customer service list → month-end closing skill. Give instructions in Korean—no coding or formulas—and verify everything against the original files. Learn from 28 real-world cases and actual Claude execution logs.
