360KJT is a platform directory and toolbox for cross-border sellers, covering Noon, TikTok Shop, Shopee, Amazon and other marketplaces across every region.
Browse by platform, by region or by tool type: profit, shipping, creator and ad calculators, plus each platform’s seller sign-up, seller center and policy links and daily news.
Every calculation runs in your browser. The site does not store the prices, costs or profit figures you type.
Platform fees show their source and check date. Where a fee has not been checked yet, enter the number from your seller center. Shipping divisors differ by carrier; example values are for illustration only.
More platforms and regions are on the way. Missing a tool? Tell us on the contact page.
