Write the brief first
Category, quantity, destination, and the job the product has to do. A guide cannot fix a vague brief.
Sourcing guides · Library
Read the album. Check the factory. Start small.
Four working guides for the decisions that come before a deposit. Read a WWTop Yupoo album, preserve the evidence when a link breaks, plan the sample-to-bulk timeline, and audit the factory — without trusting a photo.

The library
Start with the decision in front of you.
If you are reading an album, start at the top. If a link is already broken, skip to the second guide. If a deposit is close, read the timeline and the audit checklist.

A week-by-week view of sampling, approval, fabric booking, production, inspection, and freight.
10 minCollect factory evidence
The documents, questions, and visual evidence to keep before a visit or a remote verification.
11 min
How to use them
Read with a pen, not a purchase order.
Keep the evidence
Save screenshots, measurement sheets, and written messages with dates. An album can change; your record should not.
Ask for the document
When a claim matters, ask for the business licence, the test report, or the measurement sheet behind it.
Stop at the red flag
A mismatched payment name, a refusal to sample, or a price that cannot cover the fabric are reasons to pause.
Next step
A guide is a map. A factory check is the trip.
If you have a category and a quantity, we can tell you what evidence is needed, what a sample should prove, and what the quote will not include.
