Set the non-negotiables before browsing
Start with what the product must do and which details would make a candidate unusable. A broad phrase such as “high-quality shoes” cannot be compared. A brief that names footwear type, size range, upper material claim, sole requirement, color options, packing, quantity, and measurement method gives every candidate the same questions.
| Brief field | What to write |
|---|---|
| Function | Who uses the product and for what practical purpose? |
| Required specification | Dimensions, material claim, model, performance, color, or included components. |
| Acceptable variation | Which details can change without invalidating the candidate? |
| Quantity shape | Trial quantity, later quantity, and allowed color or size mix. |
| Evidence | Photos, chart, test document, sample, packing data, or source listing needed. |
| Destination context | Country or region and any relevant handling or compatibility requirement. |
| Stop conditions | Missing specification, conflicting identity, unsuitable minimum, or unverifiable source. |
Label each source by what it can actually support
- Search result or spreadsheet row
- A lead that helps locate a page. It does not establish who supplies the item.
- Yupoo album or catalog
- Visual and descriptive material that may help compare appearance and category details.
- Marketplace listing
- A separate source with its own seller, variations, price context, and platform rules.
- Direct quotation
- A dated supplier statement tied to the item, quantity, and terms named in the request.
- Sample or inspection evidence
- Information about a particular unit or batch at a particular time; it is not a guarantee for all future units.
Limit the shortlist to candidates that answer the brief
Keep only candidates that answer the non-negotiable fields. Three traceable candidates are easier to compare than twenty links with different specifications. Record why each candidate remains and which one question would remove it.
Use one comparison column for each requirement
Use a column for each required field rather than writing one long note. Keep observable evidence, supplier statements, and your own decision separate. “Photo shows two ports,” “supplier states model X,” and “compatible with our use” are three different entries.
Decide what the sample must prove before ordering it
When a sample is appropriate, define what it must answer before ordering it: measurement, material, finish, function, packaging, labeling, or another specific uncertainty. Record whether the sample reflects the same version and source as the later quotation. A sample that cannot be connected to the proposed order does not close the gap.
Store every reply beside the exact product reference
Store the question and reply with the exact product reference and date. If a later answer changes the material, MOQ, price, or packing, add a new observation. Do not let a general promise made in chat silently apply to every item from the same contact.
Pause a candidate when it no longer matches the brief
- The quoted item no longer matches the saved product code or version.
- The minimum quantity requires an order shape outside the brief.
- Required evidence is replaced by unsupported assurances.
- Packing, compatibility, or measurements remain too unclear to estimate the next step.
- Contact, payee, or source identity changes without a checkable explanation.
