I've helped dozens of sellers from Korea and Japan launch on Amazon, Walmart, and TikTok Shop. Here are the 3 mistakes I see over and over that cost sellers thousands:

1. Choosing the wrong entity structure

Many sellers register as individuals or use their home country entity without understanding the tax implications. The wrong setup can mean 30% withholding tax instead of a reduced treaty rate. Getting this right from day one saves you real money.

2. Ignoring settlement timing and currency conversion

Each marketplace has different settlement schedules and conversion policies. Amazon pays every 14 days, Walmart is bi-weekly, and TikTok Shop has its own cycle. If you don't plan your cash flow around these, you'll get squeezed — especially with FX spreads eating into your margins.

3. Not optimizing payout routing

Most sellers just accept the default payout method without comparing alternatives. Cross-border payment providers vary wildly on fees and exchange rates. The difference between a good and bad setup can be 2-3% of your total revenue.

If any of this sounds familiar, I built SellerBridge specifically to solve these problems. One-time onboarding, permanent results.
