A low unit price is useful only when the product arrives as described and you can sell it. Start with a short written buying brief: the exact item, materials, dimensions, packaging, destination, quantity and maximum total cost. Sending the same brief to each supplier makes their replies comparable.
Separate product evidence from sales claims
Ask who manufactures the item and who will issue the commercial invoice. Confirm whether the person quoting is the manufacturer, a distributor or a reseller. Request photographs of the actual packaging and a sample from the batch or specification you intend to purchase. A catalogue image is a starting point; it cannot demonstrate workmanship, durability or consistency.
For branded products, establish how the supplier obtained the stock and whether the paperwork identifies the product and seller clearly. Before paying, check the exact item in your own Seller Central account for listing or approval requirements. A supplier saying “Amazon ready” does not establish your account’s eligibility to list it.
Turn a quote into a complete comparison
- Unit price and minimum quantity, including whether mixed colours count toward that quantity.
- Sample price, production lead time and the period during which the quote is valid.
- Packaging, barcode application and any preparation charge.
- Freight destination and who pays each stage of transport.
- Inspection procedure, defect tolerance and the written remedy for a failed inspection.
- Invoice issuer, payment recipient and cancellation terms.
Worked comparison: the cheapest unit is not the cheapest order
Supplier A offers 40 units at $3.80 plus $55 transport and $20 preparation: $227 total, or $5.68 per unit. Supplier B offers 40 units at $4.20 plus $32 transport and no separate preparation: $200 total, or $5.00 per unit. These invented quotes show why comparing just $3.80 with $4.20 produces the wrong result.
Use a sample as a decision point
Write acceptance criteria before inspecting the sample. For a sewn pouch, that might include finished dimensions, seam consistency, zipper operation and packaging condition. Record the observations with photographs. If you accept a sample, refer to the agreed specification in the order rather than relying on a vague promise that production will be “the same”.
Keep the first order small enough that a failed trial will not consume your entire budget. Do not buy solely because a supplier imposes a large minimum order. A product that only works at a quantity you cannot afford is outside the current plan.
Make a buy, revise or decline decision
Proceed only when the specification, paperwork, selling eligibility and full cost agree. Revise the order if one issue can be resolved in writing. Decline if essential evidence remains missing. Keep your quotation and decision notes together so you can compare what arrives against what you approved.
