How to Verify a GPU Supplier Before You Pay

Written and maintained by Haink's procurement and allocation advisory team · Updated September 2026

Before paying a GPU supplier, a buyer should establish four things in writing. First, who the seller legally is and what role it plays in the supply chain. Second, how many links separate it from the vendor of record. Third, which state of supply is actually on offer (stock, allocation or confirmed executable supply) and which document proves it. Fourth, whether the payment goes to the contracting party on terms tied to that proof. A legitimate supplier can answer each question, and it will ask its own questions about the end user, the destination and the site. A seller who can't name its source, wants money before any upstream confirmation exists, or treats the end user and destination as details is not yet a supplier, whatever the price.

What should a buyer check before paying a GPU supplier?

The checks below apply to any large purchase of data-center GPUs, whether the hardware comes from stock or is built to order. Each one answers a different question, and none of them depends on the price.

The first three checks establish who is on the other side, the next three what is actually on offer. The last decides how much the buyer loses if any of the others is wrong.

Who is the vendor of record, and why does it matter?

The vendor of record is the party that sells to the buyer under the contract, issues the invoice and carries responsibility for the sale. For a large GPU order it should also be a party that the OEM or its authorised channel recognises as the source of the order, because that is where warranty, support and any end-user review attach.

Buying through an intermediary is normal in hardware distribution. What matters is that the seller says so plainly and names the vendor of record. A reseller that calls itself "the supplier" while passing the order on leaves the buyer with a contract against a party that controls nothing.

Authorised status can usually be checked directly. Most major OEMs publish a partner directory or will confirm partner status on request. Being an authorised partner shows a relationship with the OEM. It doesn't show that this particular offer is backed by that relationship, so it is the start of the check rather than the end of it.

What evidence should exist before any money moves?

What counts as evidence depends on the supply state being offered. A seller can offer stock, an allocation or executable supply, and each is proved by a different document from a different party. The five states and what each one proves are set out in allocation vs stock vs executable supply.

Two rules follow. The document has to come from the party that can issue it, and the buyer has to be able to confirm it with that party through contact details found independently, not the ones supplied alongside it. And the evidence has to match the claim: serial numbers for hardware that exists, an upstream confirmation for hardware that doesn't. A request for the wrong kind of evidence shows that buyer and seller are describing different things.

How can a buyer check that the hardware is genuine and properly sourced?

For hardware that exists, serial numbers are the core check. They should match the offered configuration and be recognised in the OEM's warranty or entitlement records. A mismatch, or entitlement already registered to another company, means the hardware is not what it is described as or not free to sell. Origin matters as much as authenticity: genuine hardware that left the authorised channel can arrive without transferable warranty or support. The step-by-step checks are in how to verify in-stock offers, and the risks of hardware from outside the channel in gray-market channel risks.

For hardware that doesn't exist yet, such as current-generation systems built against specific orders, there are no serials to check. The verification moves upstream: to the allocation or supplier confirmation, and to whether the seller's route to that confirmation can be traced.

Why does a legitimate GPU supplier ask about the end user?

A supplier that reaches a real source of data-center GPUs will ask who the end user is, where the hardware will be installed, which data center hosts it and what it will be used for. Those answers are what the exporter, the OEM channel and, depending on the product, volume and destination, the manufacturer review before committing supply. The applicable export requirements are determined by the exporter or supplier, not by the reseller or the buyer.

Screening applies to every route, including hardware sold from stock; its absence is not a shortcut. A seller that asks none of these questions either doesn't reach the party that reviews the order or doesn't expect it to be reviewed. Neither is a basis for payment. The end user and installation address in the documents also have to be the real ones: documents that contradict each other, or an end user and destination that stay unclear, end a legitimate process rather than delay it. What the review looks at, and why, is set out in what decides whether an allocation request is approved.

What payment terms are reasonable?

The principle is the same for every order: money committed before executable supply exists buys an offer, not supply. Payment terms vary by supplier, product and order size, but reasonable terms share a few features.

• The beneficiary is the contracting entity. The name on the receiving account matches the contract and the invoice, in the country where that entity is registered. A request to pay a related company, an agent or an account in another jurisdiction needs a written reason.
• Each payment is tied to a document that already exists. A deposit against a named-supplier confirmation and a matching purchase order is a different risk from a deposit against a quotation.
• Bank details are confirmed independently. Changes to payment instructions sent by email or messaging are a common route for payment diversion, including from a genuine supplier's compromised mailbox. They should be confirmed by a call to a number the buyer already holds, not one given in the same message.
• Instruments that tie payment to documents are available. Letters of credit and similar arrangements release money against specified documents rather than trust. They add cost and time, which is often a fair price on a first order with a new counterparty. The instruments are compared in trade finance for IT hardware.
• Risk transfer and acceptance are defined. The contract states the delivery basis, when risk passes to the buyer, who insures the shipment and how the hardware is accepted on arrival. The delivery terms themselves are explained in Incoterms for IT hardware.

Questions about financing readiness or source of funds are normal in a legitimate process, usually once a request is prepared for the supplier channel. They are a different thing from a demand for proof of funds before the seller has identified itself (see the warning signs below).

What are the warning signs of a GPU supplier scam?

No single sign proves fraud, and honest sellers sometimes trip one. Two or more together, on a large prepayment, are a reason to stop until each is explained in writing.

What can't a buyer verify alone?

Some things can't be checked from outside the supply chain, and it is better to know which ones. There is no public registry of allocations and no tool a buyer can use to look one up. Manufacturers' and OEMs' commercial rules on allocation and end users sit on top of export regulation and are not published; they reach the market through the channel. A country may be eligible under export rules and a vendor may still restrict or separately review a shipment there.

This is why tracing matters more than any single document. A buyer can't confirm an allocation independently, but it can confirm who the seller is, who its source is, and whether the named source recognises the order. Verification also has an upper limit: it shows that an offer rests on something real, but it can't turn a request into a commitment. Final approval sits upstream, and a well-documented request can still be declined or changed.

What should a buyer do after paying a supplier that may not be genuine?

Act quickly, because the chance of recovering a bank transfer falls as time passes. Ask the sending bank to request a recall of the payment and to alert the receiving bank. Stop further payments, including "release fees", customs charges or insurance said to unlock the shipment. Keep every contract, invoice, message and set of bank details.

Report the loss to the police and to the national fraud-reporting body where the buyer is based; in the United States that is the FBI's Internet Crime Complaint Center (IC3). Take legal advice in the jurisdiction of the receiving account. Be wary of anyone who contacts the buyer afterwards offering to recover the funds for an upfront fee.

Frequently asked questions

How can I tell if a GPU supplier is legitimate?

Establish who the seller legally is and what its role is, how many links separate it from the vendor of record, which supply state it is offering and which document proves it, and whether payment goes to the contracting entity against that document. A legitimate supplier answers these questions and asks its own about the end user, destination, site and intended use.

Is it normal for a GPU supplier to ask for end-user information?

Yes. End-user and destination screening applies to every route, including hardware sold from stock. A supplier that reaches a real source has to answer those questions upstream, so it asks them. A seller that never asks is a reason for caution, not a convenience.

Should I pay a deposit before the supplier confirms the order?

Money committed before executable supply exists buys an offer, not supply. A deposit is easier to justify once the named supplier has confirmed the order in writing on stated terms and the purchase order matches that confirmation. Documentary instruments such as letters of credit tie payment to documents rather than trust.

Can I check whether a reseller really has an NVIDIA allocation?

Not independently: there is no public registry of allocations. What a buyer can do is ask which party assigned the allocation, for whose order and deployment, and in what document, then confirm that document with its issuer through contact details found independently. A claim that NVIDIA approved a deal needs written confirmation from the party concerned; NVIDIA does not take part in every order.

Does buying from an authorised partner remove the need to verify the offer?

No. Authorised status shows a relationship with the OEM. It does not show that a particular offer is backed by that relationship, so the supply state and its proof still have to be checked.

What should I do if I think I have paid a fraudulent GPU supplier?

Ask the sending bank at once to request a recall of the payment, stop any further payments including so-called release or customs fees, keep all documents and messages, and report the loss to the police and the national fraud-reporting body; in the United States that is the FBI's Internet Crime Complaint Center (IC3). Take legal advice and be wary of anyone offering to recover the funds for an upfront fee.
