Sourcing Products From Suppliers — A Checklist for Small Stores

The first supplier quote is not the cost of the product. It is the opening line of a much longer calculation: samples, packaging, inspections, freight, duties, defects, payment terms, and the time it takes to fix an order that arrives wrong.

For a small store, one bad purchase order can trap months of cash in inventory you cannot sell. The goal is not to find the cheapest supplier. It is to find a supplier who can repeatedly deliver a compliant product, at an all-in cost your margin can support, without requiring a heroic amount of supervision.

Use this checklist before you send a deposit.

1. Write the product brief before asking for quotes

If three suppliers quote three slightly different products, their prices tell you nothing. Give each one the same brief:

• materials, dimensions, colors, finishes, and tolerances
• required packaging, labels, inserts, and barcodes
• target order quantity and acceptable minimum order quantity (MOQ)
• destination, shipping term, and desired delivery window
• required tests, certifications, or regulatory documents
• what counts as a defect and your acceptable quality limit

Add photos or a marked-up drawing wherever words could be interpreted two ways. Ask the supplier to state every assumption and exception in writing. A useful quote should separate unit price, tooling, samples, packaging, and shipping rather than hiding them in one number.

2. Verify that the supplier is a real business

A polished marketplace profile is a lead, not due diligence. Ask for the supplier's registered legal name, business address, registration number, factory address, and bank beneficiary name. Confirm the business in the relevant government registry where one is available. The beneficiary on the invoice should make sense for the company you vetted; a last-minute request to pay an unrelated personal account is a reason to stop.

Ask whether you are speaking with the factory or a trading company. Either can work. What matters is knowing who controls production, who owns the tooling, and who is responsible when specifications are missed.

For branded or licensed goods, verify the supplier's authorization. Search the name and marks through the USPTO trademark search and get documentary permission from the rights holder rather than relying on a supplier's reassurance.

3. Check the rules for the exact product

Compliance belongs to the seller and importer too; it cannot simply be delegated to a factory. Requirements change with the product, materials, intended user, claims, and destination market.

For products sold in the United States, start with the Consumer Product Safety Commission's small-business resources and its Regulatory Robot to identify potentially applicable product-safety rules. Children's products can require third-party testing and a Children's Product Certificate; the CPSC explains the certificate requirements on its official guidance page.

If you import, review U.S. Customs and Border Protection's importing guidance before ordering. Confirm the tariff classification, estimated duties, country-of-origin marking, and who will act as importer of record with a customs broker. Do not accept “duty free” or “DDP” as an explanation of how the shipment will legally enter the country.

Claims need checking as well. For example, an unqualified “Made in USA” claim has a specific standard; read the FTC's Made in USA guidance before printing it on a package. Depending on what you sell, other agencies and state rules may apply. When the answer is unclear, pay a qualified compliance professional before paying for inventory.

4. Order a production-quality sample

Do not approve a product from catalog photos. Buy a sample made with the proposed materials, finish, packaging, and branding. Test it as a customer would: open it, assemble it, wash it, wear it, charge it, or ship it across the country as appropriate.

Record the approved sample with dated photos, measurements, and notes, then make it the reference sample in the purchase order. A sample proves what a supplier can make once. It does not prove what every unit in a production run will be, so keep inspection in the plan.

5. Calculate landed cost, not unit cost

Put every expected cost on one sheet:

• product and packaging
• samples, molds, tooling, and setup fees
• inspection and laboratory testing
• freight, insurance, duties, taxes, and customs-broker fees
• payment and currency-conversion fees
• storage and fulfillment
• an allowance for defects, replacements, and returns

Divide the full shipment cost by the number of sellable units, not the number ordered. Then run that number through your true profit per order calculation. A low factory price can become the expensive option once bulky freight, duties, and a higher defect rate are included.

6. Put the deal in a purchase order

Chat messages are useful for discussion, not for defining the order. Your purchase order or supply agreement should identify:

• the exact specification and approved sample
• quantities, unit prices, and what the price includes
• production milestones and delivery deadline
• shipping term and named destination
• inspection rights and acceptance criteria
• the remedy for late, short, defective, or noncompliant goods
• ownership of molds, artwork, and other intellectual property
• payment schedule and refund conditions

Spell out which version controls if the purchase order, invoice, and message thread disagree. For meaningful orders, have a lawyer familiar with the supplier's jurisdiction review the agreement.

7. Protect the first payment

Avoid paying the entire order before production when you have no history with the supplier. Tie payments to clear milestones, use a payment method with appropriate commercial protections, and independently confirm changed bank details using a known contact method. Never let an urgent payment request bypass verification.

Start with the smallest run that can test production quality and real customer demand without breaking your cash flow. A higher per-unit cost on a pilot order is often cheaper than a low price on months of unproven inventory.

8. Inspect before the balance and shipment

Agree on the inspection standard before production starts. For a first order, use an independent inspector when you cannot inspect in person. The report should check quantity, workmanship, measurements, function, packaging, labels, and carton markings against the purchase order and approved sample.

Do not treat “inspection passed” as a substitute for required laboratory testing, and do not let the supplier choose which finished units are examined. Resolve failures in writing before releasing the final payment or authorizing shipment.

9. Keep a supplier scorecard

After every order, record on-time performance, defect rate, response time, accuracy, and total landed cost. Save certificates, test reports, purchase orders, inspection reports, shipping records, and corrective actions in one place.

A second qualified supplier for a best seller is useful insurance, but splitting tiny orders across many factories creates more work than resilience. First make one relationship repeatable; then qualify a backup using the same process.

The one-page go/no-go check

Before paying a deposit, you should be able to answer yes to all of these:

• Is the legal business and payment recipient verified?
• Is the product specification unambiguous?
• Have I approved a representative sample?
• Do I know which safety, labeling, testing, and import rules apply?
• Do I possess verifiable documents for every required test or claim?
• Does the landed cost leave enough margin after defects and returns?
• Are quality standards, inspection, delivery, payment, and remedies written down?
• Can the business survive if this order is late or unsellable?

If the answer to the last question is no, the order is too large. Supplier sourcing is not won by negotiating the final few cents from a quote. It is won by removing ambiguity before your cash leaves the bank.
