START HERE / BUYER ROUTE MAP
Find the sourcing route that matches the work in front of you.
You do not need to read a whole sourcing library before you know where to begin. Start with the stage you are actually in, make the current buyer question specific, then follow only the next connected guide or support route.
Direct answer: choose the new-product route when you need to define and research; choose supplier review when you need evidence before a commitment; choose control and handover when the product or order is already moving.

THREE STARTING POINTS / PICK THE WORK STAGE, NOT A GENERIC PACKAGE
The route becomes clearer when the current work is named honestly.
ROUTE 01 / NEW PRODUCT
I need to turn an idea, reference, or early sample into focused supplier work.
Begin when the product, target buyer, quantity context, materials, finish, packaging, specification, sample question, or supplier search is still being defined.
ROUTE 02 / SUPPLIER REVIEW
I have a supplier lead, quotation, sample, or concern that needs better evidence.
Begin when a supplier claim, document, product fit question, quotation, sample response, factory visit, or production concern needs a more organised review.
ROUTE 03 / PRODUCT OR ORDER MOVING
I need to keep a changing product, quality question, production checkpoint, or handover visible.
Begin when samples, packaging, quality, changes, production updates, shipping documents, or responsibilities are moving across more than one party.
THE DECISION RECORD / BRING ONLY WHAT HELPS THE NEXT QUESTION
A useful sourcing route does not begin with every document you own.
It starts with the product reference, current stage, named question, information already available, uncertainty, and the buyer decision that needs to be prepared.
1 / The current product or supplier reference
Image, sample, specification, supplier name, quotation, production reference, or existing handover record.
2 / The stage you are actually in
Research, supplier review, sample revision, quality, production, or handover—not the entire project history.
3 / The question that needs a better answer
Product fit, evidence, quote context, sample change, quality point, timing question, document, or next owner.
4 / The buyer decision that comes after the answer
Clarify, compare, request more evidence, move to sample, plan a check, update a record, or pause.
BUYER PROFILES / THE SAME FACTORY QUESTION CAN START IN DIFFERENT PLACES
Choose the working context closest to yours.
SELLER OR E-COMMERCE BRAND
You are connecting the product to a marketplace, brand, or launch plan.
Start with product context, supplier evidence, sample questions, packaging, and the stage-specific decision in front of you.
FIRST ORDER OR SMALL BUSINESS
You are building a more confident first route with limited information.
Start by making the product, quantity, sample, supplier, and decision questions clear enough to become reviewable.
EXISTING SUPPLIER OR CURRENT ORDER
You already have a supplier or product history that needs a clearer next record.
Start with the existing supplier, product version, document, sample, quality point, or production concern that needs an owner.
KEEP THE ROUTE PRACTICAL / NOT OVER-PROMISED
A better route makes the next question clearer. It does not remove every sourcing decision.
What the route map can help you do
Choose a starting guide, identify the current product or supplier record, name the decision question, and connect that question to a more practical next resource or support conversation.
What the route map does not decide
This guide does not verify a supplier, approve a product, decide a payment, select a supplier, predict an outcome, confirm compliance, or replace appropriate legal, financial, tax, technical, quality, customs, shipping, insurance, or product-safety advice.
When to start a buyer brief
Start when you can share a current product or supplier reference, stage, question, and the decision that needs clearer preparation. A brief can be short when it names the real work in front of you.
THE NEXT USEFUL ROUTE
Bring the current record and the buyer question that needs a clearer next move.
Start with your product or supplier context, current stage, what is already known, and the uncertainty that needs an owner.
