LEAN
One clear task, short lines of communication, and at the end something you can actually work with.
Working for your purchasing team in China
Your China supply chain.
Finally under control.
We are based in Nanjing and work for the purchasing teams of industrial companies in Germany, Austria and Switzerland. We check your suppliers, build new sources of supply and track whether your existing suppliers carry out the actions they have agreed to. What we do and what it costs is agreed in writing before we start.
You make the call – we get you the facts.
HOW WE WORK
TRANSPARENT
We keep three things separate: what is backed by evidence, what the supplier merely says, and what is still open.
ON THE GROUND
We clear up open questions where the parts are made – in Chinese and during your supplier's working hours.
INDEPENDENT
You are the only one who pays us. No commission from factories, no markup on the unit price.
Your starting point
Which situation applies to you?
Start with your problem, not with our service catalogue. Each card shows the right place to start and what it costs.

Evidence before commitment
What do we actually know about this source?
A source you have found is not yet a qualified source. For a specific product and revision, Q0–Q5 shows what the evidence supports and what remains open.

Practical knowledge
Practical know-how for purchasing teams.
In our articles we show with examples how we assess suppliers, cost and quality.
Where disputes are resolved matters as much as price and payment terms
Buyers negotiate price, lead time and payment terms but often copy the dispute clause from a template. It can determine whether you can enforce claims against a Chinese supplier.
One quotation – but on what basis? Where suppliers read your drawing differently
A second look is worthwhile even with one supplier and one quotation. Is machining missing, the material merely “equivalent”, or the coating unspecified? The attractive price can later lead to a surcharge or a complaint.
Market context
