Key Takeaways
- A five-minute supplier check can help small businesses identify basic risks before money changes hands.
- Buyers should verify a supplier’s physical address, contact information, refund policy, and product documentation before ordering.
- Independent reviews can reveal recurring problems that may not appear in testimonials published on a supplier’s own website.
- A small test order with careful recordkeeping can help a business evaluate a supplier before committing to larger volumes.
- Repeated complaints, missing documentation, vague refund terms, and pressure to place large orders are warning signs worth taking seriously.
What this guide covers
Most small businesses find a new supplier the same way: a search, a decent-looking website, a price that beats the last vendor. Then they place an order and hope.
Usually it works out. When it doesn’t, the cost lands on the buyer, whether it’s a shipment that never comes, a product that isn’t what the listing said, or a refund policy that turns out to mean nothing. The FTC’s guidance for businesses that buy online makes the same point in plainer terms: the time to check a seller is before money moves.
I run an online supply business, which means I sit on the other side of this every day. This guide is the short checklist I’d want any buyer to run on us, and on anyone else: a real address and a real person, the refund policy, the documentation the product should come with, the reviews the seller doesn’t control, and a small first order paid safely. It ends with the red flags that should stop an order on their own.

Can you find a real address and a real person?
Look for a physical business address, a phone number that’s answered, and an email address that isn’t a contact form. Then check that the address exists and matches the business.
A supplier that can’t be located is a supplier that can’t be held to anything. That is the whole reason this check comes first. Everything else on the list assumes there is someone on the other end who can be reached when something goes wrong, and a website alone doesn’t prove that.
Have you read the refund policy before you need it?
A real policy says what happens in specific cases: damaged goods, wrong items, late shipments. Vague promises like “satisfaction guaranteed” with no terms are a warning. So is a policy you can only find after checkout.
Read it now, while nothing is wrong. A policy that is easy to find and specific about outcomes tells you the supplier has thought about what happens when an order fails. One that is hidden or vague tells you the opposite, and you will find that out at the worst possible moment.
Does the product come with the documentation it should?
Almost every category has a document that proves the product is what it claims. Electronics have certifications. Food has spec sheets. Chemicals and lab supplies have certificates of analysis tied to a specific batch. A good supplier publishes these or sends them on request without friction. If the paperwork is always “coming,” treat the product as unverified.
This is the part of the job I know best. In our business, each product page, for example our retatrutide peptide listing, carries the certificate of analysis for its batch, with the test results and the standard every batch has to meet before it ships, so a customer can check our work rather than take our word for it. Any supplier in a quality-sensitive category should be able to do something similar.
Have you checked the reviews the seller doesn’t control?
On-site testimonials are curated by definition. Look at independent review platforms, industry forums and the Better Business Bureau instead.
A few negative reviews are normal. What matters is how the business responded to them, and whether the same complaint keeps showing up. One late shipment is a bad week. The same late-shipment complaint across months, with no reply from the business, is a pattern you are about to join.
Are you starting small and paying safely?
Place a small first order before committing to volume, and keep the receipts, tracking and correspondence together. A supplier is a risk decision as much as a price decision, and a small test order is the cheapest way to find out what you’re dealing with.
The U.S. Small Business Administration’s business guide is a good free place to think through the rest of how you manage vendors once the first order has landed and you are deciding whether to keep them.
How to run the five-minute supplier check: step by step
- Locate them. Find a physical address, a phone number that’s answered, and a real email address. Confirm the address exists and matches the business.
- Read the refund policy. It should name specific cases: damaged goods, wrong items, late shipments. It should be findable before checkout.
- Ask for the documentation. Certifications, spec sheets, or a certificate of analysis tied to the batch, depending on the category. It should arrive without friction.
- Read outside reviews. Independent platforms, industry forums and the Better Business Bureau. Look at responses and repeated complaints, not just the star count.
- Order small and keep records. A test order first, with receipts, tracking and correspondence filed together.
Five minutes, start to finish, and most of it is reading.
What are the red flags?
- No physical address, or an address that doesn’t match the business.
- A phone number nobody answers and an email that is only a contact form.
- “Satisfaction guaranteed” with no terms, or a refund policy that only appears after checkout.
- Documentation that is always “coming” and never arrives.
- The same complaint repeating across outside reviews with no response from the business.
- Pressure to commit to volume before a first order has been delivered.
Any one of these is a reason to slow down. Two or more is a reason to look elsewhere.

Bottom line
None of this takes long. Five minutes of checking addresses, policies, documents and outside reviews filters out most of the problems before they cost you anything. And the suppliers worth keeping won’t mind being checked. The good ones publish the answers before you ask.
Common questions
What is the first thing to check about a new supplier? Whether they can be located: a physical address that exists and matches the business, a phone number that’s answered, and a real email address. A supplier that can’t be found can’t be held to anything.
What should a refund policy actually say? What happens in specific cases such as damaged goods, wrong items and late shipments. Vague promises with no terms, or a policy hidden until after checkout, are warnings.
How big should a first order be? Small. A test order is the cheapest way to learn what a supplier is like, and keeping the receipts, tracking and correspondence together gives you a record if anything goes wrong.
