Wholesale Supplier Vetting Checklist: 10 Checks Before Your First Purchase Order

A first purchase order is the most dangerous money in wholesale. After it, you have a track record to judge; before it, you have a website, a chat window and a price list — and every one of those can be faked. Vetting is how you replace impressions with evidence. The 10 checks below are the ones to run before money moves, in the order that kills bad suppliers fastest: identity first, product legality second, price realism third, and payment safety last, because a supplier who fails an early check never reaches your bank account. If you would rather have the checks run for you, ZAXIUS's free audit includes a supplier shortlist review — but the checklist itself is free, and it starts here.

Business Verification: Documents to Ask For, and How to Check Them

Check 1 — the licence exists and is theirs. Ask for the business licence or company registration, in the name of the company you will be paying. Legitimate suppliers send this without ceremony; it is the wholesale equivalent of showing ID. What you are looking for is boring consistency: a real registration, in a real jurisdiction, for a company whose name you can say back to them.

Check 2 — the names all match. This is the check that does the real work. The company name on the licence, the name on the bank account they ask you to pay, the name on their invoices and the name on their website should be one and the same company. Where a public company registry exists in their country, look the registration number up rather than admiring the document. Addresses should line up too: a registered address unrelated to any address they trade from is a question, and on a first order every mismatch is a question you resolve in writing before payment, not a detail you wave through because the price was good.

Authenticity and Authorisation: The Brand-Approval Question

Check 3 — for branded goods, ask the authorisation question directly. Can this supplier show they are authorised to sell the brand — an authorisation letter from the brand, or an invoice chain from an authorised distributor? This is not pedantry. Marketplaces demand exactly this paper trail when a listing gets flagged, and genuine stock bought without it can still be seized as a listing and stranded as inventory. A supplier who sells branded goods but cannot explain their right to sell them is telling you the risk transfer is intentional: theirs to yours.

Check 4 — run the infringement sniff test on unbranded goods too. Product designs, packaging artwork and logos can infringe trademarks and design rights even when no famous brand is involved. Ask who owns the design, and be wary of catalogue photos that are visibly lifted from a brand's own storefront. Our guide to finding wholesale suppliers for Amazon goes deeper on where authorised stock actually comes from; the short version is that a price far below the authorised channel is usually explained by the authorisation not existing.

Pricing Reality Check: Too-Cheap Quotes and What They Hide

Check 5 — sanity-check the quote against the inputs. Every product has a floor set by its materials, labour and the supplier's own costs. If a quote lands far below every comparable supplier — not 5 percent below, but dramatically below — the difference is being made up somewhere: thinner materials, a lower spec than the sample, missing certifications, or stock that is not what the listing claims. Ask what drives their price. A real supplier can answer (own factory, off-season stock, a cancelled order); a fantasy price usually cannot survive two follow-up questions.

Check 6 — pin down what the quote excludes. Unit prices are quoted on different bases: packaging included or plain, labelling extra, freight to port or to your door, inspection allowed or not. An apparently cheap quote often becomes the expensive one once the exclusions are priced in. Get the quote restated with each element named, so you are comparing like with like across suppliers — and so the purchase order can hold them to it later.

Samples, Defects and Returns: Agree Terms Before Money Moves

Check 7 — buy samples, and specify them like a contract. Paying for samples is normal practice, not a red flag. What matters is precision: the sample should be the exact product, material, packaging and labelling you intend to order, and you should keep one untouched as the reference unit. When production arrives, you are not arguing about taste — you are comparing against the sample you both agreed represents the order.

Check 8 — agree the defect and returns terms in writing, now. What defect rate is acceptable? Who pays to rework, replace or refund units that fail? What evidence — photos, counts, inspection report — triggers the remedy? These questions feel awkward before an order and essential after one. Suppliers who trade honestly answer them plainly, because the terms protect them too; suppliers who go vague at this exact point are telling you how the dispute will go. Fold the agreed terms into the purchase order itself, not a chat thread that scrolls away.

The Communication Test: Response Time and Clarity as a Quality Signal

Check 9 — score how they communicate before you need them. During vetting, you are seeing the supplier on their best behaviour, with a sale in prospect. Note the response times, and more importantly the precision: do they answer the question asked, confirm numbers back, and put agreements in writing without being chased? Ask one deliberately specific question — a dimension, a certification number, a lead-time breakdown — and judge the answer. Production problems are normal in sourcing; what separates suppliers is whether you hear about them early and exactly. A supplier who is slow and vague while courting you will not become fast and precise once your deposit is spent. Our China sourcing team treats this as a formal gate for exactly that reason: communication quality during vetting is the cheapest predictor of how an order will be managed.

Payment Terms and Fraud Guards for a First Order

Check 10 — structure the payment so a bad outcome is survivable. The standard protections: a deposit with the balance released after inspection or shipment evidence, rather than full payment upfront; payment through a channel with some recourse where the platform offers it; and above all, payment only to an account in the exact company name that passed Checks 1 and 2. The single most common thread in first-order fraud is a late request to pay a differently named company or a personal account — because the deal was urgent, the account changed, the boss said so. Treat any such request as a full stop and a re-vetting, whatever the reason given. Keep the order modest: a first order is a test you are buying information with, and its size should reflect that its main job is to prove the supplier, the product and the paperwork before real volume follows.

Run all 10 and most bad suppliers eliminate themselves — usually early, usually cheaply. If your shortlist survives the checklist and you want a second assessment before committing, ZAXIUS's free audit will review your supplier shortlist and your first-order terms against the same checks, and tell you where the remaining risk sits.
