SourceChina OS is a practical sourcing toolkit for entrepreneurs, ecommerce sellers, and small businesses buying products from China.
Instead of guessing what to ask factories, how to compare quotations, or what to check before payment, you get ready-to-use scripts, templates, calculators, checklists and sourcing workflows.
Inside you’ll find bilingual English/Chinese supplier messages, factory negotiation strategies, supplier verification checklists, RFQ and inspection templates, a 1688 sourcing cheat sheet, AI sourcing prompts, and an editable landed-cost calculator.
