Every report starts with a one-page summary: red, amber or green for each finding, the source behind it, and what to do before you pay.
A US law firm that handles cases where buyers paid and received nothing says that "at least half the time in situations like this, there is no real company there."

Common questions
Are you a law firm?
No. We find facts, deal with Chinese companies in Mandarin and coordinate. Legal advice and court action are handled by independent lawyers.
Do factories pay you?
No. We are paid by our clients only. If a partner firm we introduce pays us a referral fee, we tell you before you engage them.
How do payments work?
Quotes are free. Supplier checks, dispute assessments and consultations are paid in advance. Larger projects are set out in a written proposal.
Is your advice legal advice?
No. Our advice is practical and commercial. For a formal legal opinion we work with Chinese and UK law firms.
