Supplier Verification Checklist

Key takeaways

• The two supplier risks are fraud (they are not real) and dependence (they are your only option).
• Verification is cheap; a bad supplier can cost a whole product launch.
• Never let one supplier hold your entire product hostage: have a backup identified before you need it.
• Structure payments so trust is earned in stages, and never pay in full up front to an unverified counterparty.

The two failure modes

Supplier problems come in two distinct flavors, and they require different defenses. The first is fraud and misrepresentation: the "factory" that is actually a trading company relabeling someone else's goods, the supplier who ships a beautiful sample and a container of garbage, the counterparty who takes the deposit and evaporates. Cross-border sourcing amplifies this because your usual instincts (visiting, suing, checking references through people you know) get expensive or impossible.

The second is dependence: the supplier is perfectly real and perfectly good, and that is the problem, because they are your only source. A price increase, a quality slide, a capacity crunch, a factory fire, a port closure, or simply being dropped as a small customer becomes an existential event for your product line. Fraud costs you a deposit or a container; dependence can cost you the business, because it compounds with time and success.

The checklist below runs both defenses in order: verify the counterparty is real and capable before money moves, then structure the relationship so no single supplier can take you down. Both are boring. Both are dramatically cheaper than their absence.

Verify: are they real, and can they do the job?

Identity first. Confirm the legal business name and registration. Most jurisdictions have public registries, and sourcing platforms' verification badges are a starting point, not a conclusion. Match the bank account name to the registered company name before any wire; a mismatch ("pay our director's personal account this month") is a walk-away signal, full stop. Video-call the facility: a supplier who cannot show you the floor they claim to run is telling you something. For meaningful volume, a third-party factory audit, a few hundred dollars from established inspection firms, verifies existence, capacity, and working conditions in one visit.

Capability second. Order samples that are paid, production-line samples rather than hand-polished showpieces, and test them the way customers will use them. Ask directly about capacity, current lead times, minimums, and their other clients in your category; coherent, specific answers correlate with real operations. Check references if you can reach any, and search the name plus "scam," plus court records where accessible.

Quality third, and forever: for any real order size, pre-shipment inspection by a third party (again cheap, again standard) catches the container of garbage while it can still be rejected. Quality verification is not a one-time gate but a standing process. Established importers inspect on a cadence, because production lines drift and suppliers quietly substitute materials when their own costs rise.

Structure the money so trust is staged

Payment terms are your main risk-control instrument while trust is young. The standard opening posture: a deposit (commonly around 30%) to begin production, the balance only after your pre-shipment inspection passes, and never 100% up front to an unverified counterparty, whatever discount is dangled. Pay through channels with recourse and records; be suspicious of pressure toward untraceable methods or account changes mid-relationship (invoice-redirection fraud, a hacked email politely announcing "new bank details," is one of the most common and most expensive scams in trade; verify any change by phone on a number you already had).

As the relationship proves out, terms evolve toward smaller deposits, then open account terms where they carry you for 30 or 60 days, and that evolution is valuable working capital, which is one more reason to be a reliable, communicative customer worth extending it to.

Document everything material in the purchase order: exact specifications, tolerances, materials, packaging, labeling, inspection standards, and what happens on failure. Disputes across borders are rarely worth litigating; the leverage that actually works is staged payment, inspection before balance, and being a customer whose future orders are worth protecting.

Reduce dependence before it is urgent

Map your exposure honestly: for each critical input, how many qualified sources do you have, and how long would replacement take from a cold start? If the answer for your core product is "one source, and months," you are running a single point of failure: common, rational at small scale, and worth fixing on a schedule rather than in a crisis.

The standard maneuver is qualifying a backup before you need it: identify a second supplier, run the verification checklist, place a small real order so tooling, quality, and communication are proven, then keep them warm with occasional orders even at slightly worse unit economics. The premium you pay on those occasional units is an insurance premium, correctly named. Where volume justifies it, a deliberate split (the familiar 70/30 pattern) keeps both suppliers honest on price and quality while keeping the backup genuinely production-ready.

Watch the leading indicators of supplier trouble while things are still fine: slipping lead times, quality drift, slower communication, sudden pushes for bigger deposits. Each is a prompt to warm the backup. And diversify the geography where tariffs, shipping chokepoints, or single-country risk could bite; the freight and landed-cost math from the seasonality briefing feeds directly into whether a second-country source pencils. Dependence is measured in options: the goal is never needing the backup and always having one.

Put it to work

Run every new supplier through the gates in order: identity (registration, matching bank name, video walkthrough or audit), capability (production samples, capacity, references), quality (third-party pre-shipment inspection), and staged payments: deposit, inspect, then balance. Then score your single-source exposure and qualify a backup for anything critical before you need it.

Sources & references

Linked entries open the named source directly. Entries without a link say exactly what kind of reference they are — and how to check them yourself.

• SGS — pre-shipment inspection services (one of several global firms)
• Corlova synthesis of standard sourcing practice — The sampling → inspection → escrowed-payment workflow described here is standard, widely documented importing practice rather than one citable document; the inspection industry itself (SGS, Bureau Veritas, QIMA and others) publishes service scopes on their own sites.
