How to Find and Vet Suppliers for Your Online Store
Your supplier decides your margin, your delivery times and your product quality. It is the most consequential relationship in the business and the one most people rush.
Know which kind of supplier you need
- Manufacturers make the goods. Best pricing and the only route to a custom or branded product, but high minimum order quantities.
- Wholesalers and distributors buy in bulk and resell smaller quantities. Higher unit cost, far lower minimums — the usual starting point.
- Sourcing agents find and manage factories on your behalf for a fee or commission. Valuable when importing from a country whose language and business norms you do not know.
- Print-on-demand and fulfilment partners produce per order. No minimums, capped margins.
- Domestic wholesalers cost more per unit but ship in days, which often beats a cheaper overseas price once you count returns and lost sales.
Where to look
For overseas manufacturing, Alibaba and Global Sources are the common starting points, with Made-in-China and 1688 also widely used; 1688 serves the domestic Chinese market and generally needs an agent. IndiaMART covers a large Indian supplier base. For North American and European wholesale, ThomasNet, Faire and national wholesale directories are more relevant.
Trade shows remain the fastest way to assess many suppliers in a short time, because you can handle samples and read the people. Failing that, look at who already supplies products like yours: import records are public in several countries, and a product's packaging often names the manufacturer.
Vetting: prove they are real and capable
- Verify the legal entity. Ask for the business licence or registration number and check it against the public register in their country. A supplier who will not provide one is not a supplier.
- Separate traders from factories. Ask what else they make, their factory address and staff count. Trading companies are not automatically bad, but you should know which you are dealing with, because it affects price and quality control.
- Ask for certifications relevant to your market — CE, UKCA, FCC, RoHS, food-contact or safety approvals — and ask for the certificate, then check its number. Fake certificates are common.
- Order samples, paid for at full price, from more than one supplier. Compare the product, the packaging and how quickly and clearly they communicated.
- Request references from existing customers in your region, and actually contact them.
- Test responsiveness before you commit. A supplier who is slow to reply while trying to win your business will not improve once they have it.
Negotiating terms
Price is only one of the terms that matters, and rarely the one that hurts you.
- Minimum order quantity. Often negotiable on a first order, especially if you accept their existing colours or materials.
- Unit price by volume. Ask for the price at several quantities so you can see where the breaks are.
- Payment terms. A deposit with the balance on inspection, before shipping, is normal. Never pay the full amount up front on a first order.
- Incoterms. Agree explicitly who pays freight, insurance and duty. A cheap price is not cheap if it excludes shipping and customs.
- Lead time, in writing, separating production time from transit time.
- Defect handling. Agree in advance what happens when a batch fails: replacement, credit or refund.
Pay through traceable channels that leave you recourse. Avoid wiring money to a personal account, and be wary of any request to change bank details mid-order — that is a common invoice-fraud pattern.
Quality control
Approve a physical golden sample and keep it. It is the reference for every future batch and settles arguments quickly.
For orders of meaningful value, pay for a pre-shipment inspection by a third-party firm. It costs a few hundred and regularly saves a container of unsellable stock. Inspect on your first order with any supplier, then periodically after.
Red flags
- Pricing far below every other quote — usually a substituted material or a scam.
- Refusal to provide a business licence, factory address or samples.
- Pressure to pay quickly, in full, through an unusual channel.
- Offers to supply branded goods they clearly have no licence to make.
- Vague answers on materials, certification or lead times.
- A sudden change of bank details on an invoice.
Build the relationship
Suppliers prioritise customers who are easy to deal with: clear specifications, prompt payment, realistic timelines and consolidated questions. That priority becomes real when capacity is tight and someone's order ships first.
Keep a second approved supplier for anything that sells well, even at a slightly worse price. Single-sourcing is the risk that eventually closes stores, and the time to find the alternative is long before you need it.
