For starters, TikTok Seller Center is a free, effective foundation - track orders, view inventory, chat with customers. When you get to 20 orders per day, add CedCommerce or Order Desk ($20/month) - sync everything and reduce errors. Your Korean team is the secret weapon - use them to increase early traffic. Risk-wise, over-committing inventory is your biggest problem - confirm it's there before you "ship". Optimize? Focus on 5 popular products, not 50 failures - your $1000/day TikTok Lite effort is proving that you can scale wisely.
