CHINA COMPONENT SOURCING · BUYER-SIDE SUPPORT

Find the right source. Know what you’re buying.

A supplier can quote a part. I help you compare the options, resolve technical questions and decide what needs checking before you buy.

START WITH YOUR TASK

What are you trying to resolve?

Start with one part or one question. There is no charge to discuss fit and agree a scope.

01

I have a part number.

Compare supply routes, traceability documents and the terms behind a quote.

Discuss the source02

I need a Chinese alternative.

Separate a promising candidate from a part that only looks equivalent on paper.

Review an alternative03

I know the application.

Turn operating conditions into a brief suppliers can answer and engineers can review.

Define the brief

A CONTINUING PROCUREMENT DECISION

Should you buy the next release now?

An invented plan needs 100,000 pieces now and another 100,000 in three months. Compare two purchases with one larger order: price is only useful alongside demand certainty, storage, payment timing and document coverage.

Inspect the plan and its assumptions

Method exercise with invented demand and large-volume terms. No actual quote, supplier contact or realised saving is claimed.

Compare the smaller-batch demand scenarios
