Before your first purchase order: a supplier due-diligence checklist
A competitive quotation is only one piece of the sourcing decision. A better first order starts with questions that can be answered, documented and verified.
1. Turn the idea into a specification
Before collecting prices, describe what you actually want to buy. Include the product's function, dimensions, key materials, performance criteria, colors, packaging, intended destination market and testing or certification needs. “Make it like this photo” is not an adequate specification for a repeatable production run.
If the product is electronic, document the power requirements, component tolerances, firmware or connectivity requirements and expected environmental conditions. If it touches food, children or regulated categories, investigate the destination-market rules early rather than assuming the factory's current certifications are sufficient.
2. Verify who is making the product
Ask whether the supplier is the manufacturer, a trading company or an organization combining both. Either model can work. The important questions are who is responsible for tooling, assembly, inspection, documentation and remedying defects.
- Confirm the legal business entity and correct invoicing name.
- Request evidence of relevant production capabilities, equipment or qualified subcontractors.
- Clarify the factory address for the product that will actually be made.
- Check whether critical components are made in-house or sourced elsewhere.
- Find out who approves design changes and who owns the technical drawings.
3. Ask for a meaningful sample
A sample should prove more than appearance. Agree on a written sample checklist with measurable pass/fail criteria. Photograph or record deviations, confirm changes in writing and preserve a “golden sample” to reference during production. One good sample does not automatically predict large-batch consistency.
4. Compare complete costs, not headline unit prices
Ask for prices at different quantities, minimum order quantities, tooling charges, sample fees, packaging costs, export documentation requirements and payment schedules. Discuss Incoterms precisely: whether an offer is EXW, FOB or another basis changes which costs and responsibilities sit with the buyer.
For a product intended for an international marketplace, add transport, duties, taxes, labeling, local compliance, storage, marketplace fees, returns and warranty support. Your real margin is built from landed costs, not just a factory quote.
5. Design quality control before paying the balance
Agree on inspection points, acceptable defect definitions, test methods and what happens when a batch fails. Consider independent pre-shipment inspection when appropriate. For electrical products, safety and conformity evidence deserve a specific review, not a generic factory statement that an item is “certified.”
6. Put responsibilities in writing
Contracts should identify the buyer and supplier correctly, specify the goods and versions, milestones, payment and acceptance conditions, ownership of molds and designs where relevant, confidentiality expectations, warranty responsibilities and dispute procedures. Seek qualified professional advice for important commercial contracts.
A useful sourcing partner helps reduce uncertainty. They do not make uncertainty disappear by promising that every factory is perfect.
7. Use a pre-order decision gate
Before placing a significant order, gather the specification, final sample, confirmed commercial terms, compliance review, estimated landed-cost model and quality plan into one approval package. If a major assumption is still unresolved, assign an owner and a verification step.

This guide is educational. Supplier arrangements, trade rules, costs and investment decisions require independent project-specific verification.
