How it works

From requirement
to delivery

A structured five-stage process that protects your interests at every step — from the first conversation to final goods receipt.
01 Brief 02 Sourcing 03 Vetting 04 Negotiation 05 Delivery 5 STAGES
Stage 01
Requirements Brief
We begin with a detailed intake — technical specifications, tolerances, target volumes, delivery timeline, and budget parameters. The clearer the brief, the better the match.
Stage 02
Supplier Identification
We identify qualified manufacturers across China's optical manufacturing clusters — including Fujian, Jiangsu, and Zhejiang — using our existing supplier network and direct Mandarin-language outreach.
Stage 03
Due Diligence & Vetting
We verify business credentials, certifications (ISO, CE), production capacity, and quality management systems. Factory visits conducted on request, based on supplier location.
Stage 04
Price Negotiation & Sampling
We negotiate pricing, MOQs, and lead times directly with shortlisted suppliers — in Mandarin, on your behalf. Sample coordination and initial quality assessment included.
Stage 05
Order Management & Delivery
We monitor production progress, coordinate pre-shipment inspection, and manage logistics until goods are received. Ongoing supplier relationship management available for repeat orders.

Location
Shanghai On-the-Ground
We are physically based in Shanghai — not managing China remotely from another country. Factory visits, in-person negotiations, and real-time supplier monitoring are part of how we work.
Language
Native Mandarin, No Intermediary
Our lead is a native Mandarin speaker. Every conversation with your suppliers happens directly, without translation layers or communication gaps that distort requirements and erode trust.
Alignment
Buyer's Agent — Always
We do not accept commissions from suppliers. We are not paid by manufacturers to recommend them. Our fee comes from you, which means our interests are fully aligned with yours.
Methodology
Research-Grade Due Diligence
Our approach to supplier verification is informed by rigorous market research methodology — trained at Ipsos, the world's third-largest research firm. We verify, we don't just introduce.
