How Do I Vet Potential Wholesale Suppliers as a Reseller

A new supplier usually arrives with a price. It’s lower than what you pay now, the product list overlaps with your best sellers, and the rep can deliver next week. Whether that’s a good deal depends on things the price sheet doesn’t show: whether the company is real, whether the product is genuine and in date, and what happens when a delivery comes up short.

This guide sets out a wholesale supplier vetting process for grocers, convenience stores, specialty retailers and small distributors buying consumer goods to resell in the US and Canada. When a new vendor calls, the question becomes: how do I vet potential wholesale suppliers without a procurement department? The answer below is a set of checks a store or distributor can run before the first invoice, several of them free.

How Do I Vet Potential Wholesale Suppliers? A Supplier Vetting Process Guide

You vet a potential wholesale supplier by confirming, in order, that the business exists, that it’s allowed to sell what it’s offering, that the product is authentic and within its dates, that the terms work for you, and that you can pay without risking money you can’t recover. Then you keep checking after the first order.

The process runs in six steps, each covered below.

1. Confirm the business is real and in good standing.
2. Confirm it’s authorized or licensed to sell what it’s offering.
3. Check the product, its labels, its dates and its recall history.
4. Get the commercial terms in writing.
5. Pay safely, and start with a trial order.
6. Keep score, and re-vet on a schedule.

A directory of wholesale suppliers in the USA tells you who exists; this process tells you which of them to trust with a first order. The public lookups in the first two steps cost nothing.

Why Vetting Matters More Than Price

Counterfeit and diverted goods move through ordinary trade, and a deal that looks too good is exactly what a vetting process is built to question.

U.S. Customs and Border Protection seized 78.4 million items for intellectual property violations in fiscal 2025, with a combined manufacturer’s suggested retail price of $7.4 billion, according to its FY2025 seizure statistics. That retail value is up from $3.3 billion in fiscal 2021. Jewelry, watches and handbags top the list by value, but perfume and more than 800,000 pharmaceutical items show up in the seizures too.

Globally, the OECD and EUIPO estimate that counterfeit goods accounted for $467 billion of global trade in 2021, and their 2025 report warns that hazardous fakes, including medicines, cosmetics, toys and food, were increasingly prevalent.

Not every problem is a fake. Gray market goods are genuine products bought in one market and sold in another without the trademark owner’s consent, as the International Trademark Association defines them. For a store, diverted product can arrive with labels printed for another country, and the brand may refuse to honor returns or promotions on it.

Step 1: Confirm the Business Is Real

The first check is whether the company exists as a legal entity, is in good standing and is who it says it is. It’s also the quickest place to rule out a bad supplier.

Search the business name in the Secretary of State registry for the state where it’s incorporated. Confirm the status reads active, the formation date makes sense, and the name matches the invoice, the website and the bank account, or is a trade name (DBA) the supplier has registered. A company that claims 20 years in distribution but was formed last spring deserves a question.

Three more checks are quick and free. Search the Treasury Department’s OFAC sanctions list for the company and its owners, look up its Better Business Bureau profile for complaint patterns, and confirm the address is a warehouse or office rather than a mailbox.

For Canadian suppliers, the Canada Revenue Agency’s GST/HST registry lets you “confirm that the business charging you GST/HST is registered,” and Global Affairs Canada publishes a Consolidated Canadian Autonomous Sanctions List to check names against.

Finally, ask for two or three references from stores or distributors in your channel, and call them. Ask what shipped short, how damages were handled and whether invoices matched deliveries.

Step 2: Confirm the Supplier Is Allowed to Sell It

A real business still has to be allowed to sell what it’s offering, and that takes two different checks: whether the brand has authorized it, and whether it holds the licenses the product category requires.

Authorization From the Brand

Ask whether the supplier buys from the brand or from a master distributor. Some brands publish lists of authorized distributors, and where they don’t, the brand’s own sales team can confirm on a large deal.

A signed letter of authorization is worth requesting on a big or brand-specific order, but it isn’t standard on every wholesale deal, and a supplier selling genuine secondary-market goods may legitimately not have one. What should worry you is a supplier who can’t say where the product came from.

Authorization also brings obligations. Brands that sell through authorized channels may set a minimum advertised price policy, and a store that advertises below it can lose access to the brand. A supplier who pitches stock as something you can advertise below that floor is telling you it sits outside the brand’s channel, even when the product itself is genuine.

Public Records You Can Check

Several US and Canadian agencies publish records you can search yourself. The table lists the main ones, with what each can and can’t tell you.

One record you can’t check is FDA food facility registration. Under 21 CFR 1.243, the list of registered facilities is not subject to disclosure under the Freedom of Information Act, so ask a supplier that packs or stores FDA-regulated food for its registration number and keep it on file.

Some businesses, such as farms and retail food establishments, are exempt from registering, and any website selling “FDA registration lookups” is a private service, not an official one.

For alcohol and tobacco, state licensing adds another layer, so ask for the state license as well as any federal permit.

Step 3: Check the Product and Its Paper Trail

A product check plays a crucial role in protecting the supply chain, since genuine goods can still be the wrong product: short-dated, relabeled, or pulled from a recalled lot. Check the goods and the paperwork before anything goes on a shelf.

Ask for samples from more than one lot and compare them with product you know came from the brand, looking at the packaging, print quality, UPC, and lot and date codes. Ask what quality control measures the supplier uses, and review past performance on similar products when possible. Labels should carry the language and information your market requires, including ingredients and allergens.

Search both the supplier and the brand in FDA’s Enforcement Report before the first order. Then make sure every delivery carries lot information you can trace, because lot traceability is what lets you pull only the affected cases when a recall does land, instead of every case of that product on hand, while also helping track key components of supplier performance during recalls.

Step 4: Get the Commercial Terms in Writing

A supplier can pass every legitimacy check and still be a poor fit. Step 4 is where you set the criteria for choosing the right vendors based on reliability, capabilities, and costs, and the table shows what to pin down.

Minimums deserve the closest read, because a minimum order quantity set for a chain can quietly turn a small store’s trial into months of stock. Ask the supplier to load the agreed terms into your account in its own system, not just a sales email, so the first invoice already reflects them. These details also help you choose reliable business partners.

Step 5: Pay Safely and Start Small

Payment is the step where a bad supplier can take money you won’t get back, so do your due diligence before the first purchase from any new supplier and be strictest here.

J.P. Morgan’s vendor vetting tips advise against agreeing to upfront payment in full, suggest an escrow service where it applies, and recommend checking invoices against your research and calling a number on file to confirm any request to change bank details. That last habit matters because a legitimate supplier’s email account can be compromised, and a “new bank details” email is exactly the request those tips tell you to verify by phone.

For a first order with a new supplier, pay by a method you can dispute or recover, such as a business credit card or a check handed over once the delivery is counted.

Match the account name to the business you verified, for example with a bank letter or voided check in the business’s name, and keep the order small enough that losing it wouldn’t hurt. A trial order shows you the fill rate, the dates on arrival and how the invoice compares with the delivery, and it also shows whether the supplier is reliable in practice, which no reference call can.

Expect the paperwork to run both ways. In US states with sales tax, a legitimate wholesaler will ask for your resale certificate so it doesn’t charge tax on goods you’ll resell, which is the practical payoff of holding a wholesale license in the first place.

A single uniform exemption certificate, published under a multistate sales tax agreement, is accepted in all 24 of its member states. California, Texas, Florida, Illinois and Pennsylvania aren’t members but accept a separate multistate resale certificate from the Multistate Tax Commission, each with its own conditions, and New York accepts neither, so check your state’s rules before the first order.

Canada works differently. There’s no resale certificate for GST/HST: registered businesses pay it and claim it back as an input tax credit, while British Columbia exempts goods bought for resale from its provincial sales tax.

Step 6: Keep Score With Performance Monitoring After the First Order

Vetting doesn’t end with a clean first delivery; ongoing performance monitoring is part of the process. Track a handful of numbers for every supplier: fill rate on your core items, on-time delivery, invoice accuracy, damages, price changes, overall supplier performance, and any other factors you review each quarter. Re-run the registry, sanctions and license lookups from Steps 1 and 2 at least once a year and whenever something material changes, such as new ownership, new bank details or a new product line.

Suppliers that give you a B2B ordering app with your order history make that scorecard easier to keep, because your past orders are already on record and the ongoing review helps confirm their capabilities still match your needs.

Red Flags and Supply Chain Risks That Should Stop the Deal

Some signals are serious enough to end the conversation, or at least pause it until the supplier explains.

• They’ll take a first payment only by crypto, gift card or a consumer payment app.
• The payment goes to a personal account, or to a company name that doesn’t match the one you verified.
• Bank details change by email partway through the deal.
• The price is far below every other quote, with no explanation.
• There’s no verifiable address or phone number, or the address is a mailbox.
• They won’t provide references, an itemized invoice or a written returns policy.
• They push for a decision today.
• They promise outcomes they don’t control, such as guaranteed sell-through.
• The product is short-dated or relabeled, or its packaging is printed for another country.
• They can’t or won’t say where the product came from.

Some of these, like a request to pay a personal account, are enough on their own. Others can have an innocent explanation, and asking about them is part of the process. When two or three show up together, walk away.

What a Well-Run Supplier Looks Like

Positive evidence comes from how a supplier runs day to day, because a well-run wholesaler plays a crucial role in operations when its records are easy to pull, invoices match deliveries, reps follow through, and those habits make the supplier more dependable over time. A well-run wholesaler can tell you your price, your order history and your open invoices quickly, whether through a rep or a portal, gets the invoice to match the delivery, and sends a rep who knows what you bought last time.

Proglo World, a Las Vegas wholesale distributor that supplies retailers and resellers across grocery, beauty, household, pet and other categories, is a useful model. It’s an official distributor for hundreds of national and international brands, including Unilever, Bob’s Red Mill and Twinings, and it follows those brands’ minimum advertised price policies.

When it launched at the start of 2026, it took orders on a general-purpose marketing platform or on paper. After it moved order capture, customer records and payment tracking into SimplyDepo, its case study reports more than 200 orders in a single month, per-rep daily order capacity rising from a handful to 10 or more, and every payment, check number included, recorded against the order it paid.

Order records like those are what a reseller wants a supplier to keep.

Make Your Checklist a Habit

If you came here asking how do I vet potential wholesale suppliers, the answer is a routine rather than a single check.

The wholesale supplier vetting process stays short when you run it the same way every time, which supports informed decisions: registry and license checks, a product and paperwork check, written terms, a small first order paid safely, and a scorecard after it. Build it into how you add any new supplier, and the checklist gives practical tips and useful tips you can apply each time you evaluate new wholesale suppliers, so a too-good quote becomes a question you ask the supplier.

Small distributors sit on both sides of this checklist, vetting their suppliers while store accounts run the same checks on them. SimplyDepo covers the second side: each account’s orders, invoices and payments stay tied together, so a store asking what shipped or what it owes gets a quick answer. It won’t vet your own suppliers, but if you’re the one being vetted, you can book a demo.
