Vendor KYC Verification: How It Works, Required Documents, and Common Failures

In December 2019, the US Department of Justice sentenced Evaldas Rimasauskas to five years in prison after a business email compromise scheme caused two US internet companies to send more than $120 million to accounts he controlled. He had registered a Latvian company with the same name as a real Asian hardware manufacturer. Fraudulent emails then redirected payments, while forged invoices, contracts, and letters helped support the transfers.

The case shows why teams need to verify suppliers independently and confirm payment instructions through trusted channels, reinforcing their role in preventing fraud and building trust in the process.

What is vendor KYC, and what does it verify?

Vendor KYC verifies that a supplier is legally registered, owned by the claimed individuals, and safe to engage, helping teams feel assured of thorough due diligence before signing contracts or releasing payments.

Because companies change owners, sanctions lists update, and criminals can replace payment details, maintaining continuous oversight helps teams stay confident in the vendor record’s accuracy and security.

The comparison below shows how vendor KYC differs from customer KYC (Know Your Customer) and general KYB (Know Your Business).

The direction of risk matters. Customer KYC protects access to your services, while vendor KYC also protects the money and sensitive access you give to suppliers. As a result, bank account checks and change controls are central to a vendor program.

Why vendor KYC matters for procurement and compliance teams

Third-party risk reaches beyond invoice fraud. Verizon’s 2026 Data Breach Investigations Report found that third parties were involved in 48% of breaches in its dataset, a 60% increase over the previous year. Vendor KYC cannot test a supplier’s cyber controls, so it should sit within a broader third-party risk program. It does, however, help ensure that you assess the correct legal entity and owners before granting access.

Meanwhile, the Association for Financial Professionals reported in its 2026 Payments Fraud and Control Survey that 76% of organizations experienced attempted or actual payments fraud in 2025. The survey also highlights concerns about the impersonation of executives, vendors, and other trusted parties through voice and video. Therefore, a bank detail change should never be approved only because the request looks or sounds convincing.

Company data is also becoming more reliable in some markets. From 18 November 2025, Companies House introduced compulsory identity verification for new UK directors and people with significant control, while existing individuals are being phased in according to their due dates during a 12-month transition. A missed applicable deadline should trigger review, although it is not proof of fraud by itself.

How does the vendor KYC verification process work?

A practical vendor KYC process has four connected layers. This is an operating framework, not a universal legal standard. First, verify the entity, then identify the people behind it, confirm where payments will go, and keep the record up to date. Each layer reduces the assumptions carried into the next one.

1. Verify the legal entity

Start with an official company registry or authoritative source in the supplier’s home jurisdiction. Confirm the legal name, registration number, registered address, and current status. If discrepancies arise between these details and your records, pause onboarding, document the differences, and escalate for further verification before proceeding.

2. Identify the owners, directors, and authorized representatives

A registry match proves that the company exists, but it does not explain every ownership or control risk. Identify the ultimate beneficial owners through any holding-company layers and apply the threshold required by the relevant jurisdiction or your policy. In higher-risk cases, verify the individual as well as the company, and confirm that the person signing the contract is authorized to act on behalf of the company.

Screen relevant owners, directors, and controllers against sanctions, politically exposed persons (PEP), and adverse media screening sources according to your risk policy. However, a PEP match is not an automatic reason to reject a supplier. It is a risk indicator that may require more information, senior approval, or enhanced monitoring.

3. Validate the payment account and every change request

Confirm that the payment account belongs to the verified legal entity where account-name matching or reliable bank evidence is available. More importantly, repeat the check when bank details change. Validate the request through a channel the requester does not control, such as a known phone number from the original contract, and require a second approval before changing the vendor master record.

4. Regular reviews help maintain accurate records and reduce the risk of fraud or compliance breaches

Verification becomes less reliable as the supplier changes. Monitor relevant sanctions and ownership events, and reopen the file when directors, control, bank details, or business status change. Reviews can also be triggered when a dormant vendor becomes active again. The review frequency should reflect the supplier’s risk, applicable law, and your policy rather than a single calendar rule for every vendor.

Where vendor KYC programs commonly fail

The vendor is verified once and never reviewed again

A clean onboarding result is only accurate for that point in time. Without trigger-based reviews, ownership or sanctions changes can remain hidden until the next scheduled refresh. Therefore, define the events that automatically reopen a supplier file before the vendor is approved.

Documents are collected without checking the source

A certificate of incorporation can be genuine, altered, or simply unrelated to the company requesting payment. Where possible, compare submitted documents with an official registry and record which source supported the decision. This gives reviewers evidence, not just a folder of PDFs.

Bank details are treated as ordinary admin data

Changing a payment account can shift the risk from a verified supplier to a criminal in a single email. Separate bank detail changes from routine profile updates, use independent confirmation, and keep an approval log. This control protects the payment path even when the supplier itself is legitimate.

Every supplier receives the same checks

Heavy checks on low-value, low-risk suppliers create delays and manual work without improving the most important decisions. Meanwhile, a light check can miss the risk in a high-spend or cross-border relationship. Risk tiers help teams apply more evidence and monitoring where the potential loss is higher.

Procurement, compliance,e and finance use different records

A supplier can pass compliance while finance pays a different account if the teams do not share the same record. One vendor profile should show the verified entity, owners, risk decision, bank evidence, approvals, and review triggers. This gives every team the same facts before a contract or payment is released.

Vendor KYC checklist: documents and evidence to collect

The exact evidence depends on the supplier’s country, sector, ownership, and risk. Collect baseline information in a single request to reduce friction, then request additional evidence only when the risk or law requires it.

Business registration evidence: Use a recent official registry extract or certificate that shows the legal name, registration number, status, and registered address.

Tax identification: Collect the relevant VAT, GST, employer, or national tax number and compare it with the jurisdiction and invoice details.

Ownership and control information: Request a UBO declaration and an ownership chart for layered structures. Where required by risk or rules, verify the identities of the relevant owners and controllers.

Authority to act: Confirm that the person signing the contract or changing payment details can act on behalf of the supplier. This may require a board resolution, power of attorney, or another reliable record.

Bank-account evidence: Use a bank letter, account-name match, or equivalent evidence in the legal entity’s name, then validate it independently before the first payment and after any change.

Licenses and accreditations: Confirm any sector permissions the supplier needs, such as a transport, food, healthcare, or financial services license, directly with the issuing authority where possible.

Insurance and financial standing: For material contracts, collect appropriate insurance evidence and financial information that supports the supplier’s ability to deliver.

Screening and review record: Keep the sanctions, politically exposed persons, and adverse-media results used for the decision, together with the reviewer, date, outcome, and next trigger or review point.

Procurement usually opens the vendor file, while compliance and finance contribute risk and payment controls. The process works best when all three teams use a single record and a single trigger list. Otherwise, important evidence gets trapped in emails, and the supplier can change between departmental hand-offs.

Is vendor KYC mandatory for every business?

No single universal law requires every organization to run the same vendor KYC process. Duties vary by country, sector, and relationship. Sanctions rules, anti-bribery controls, regulated outsourcing requirements, public procurement rules, and contract terms may all require some form of supplier due diligence. However, customer due diligence rules do not automatically impose identical KYC requirements on every supplier.

Therefore, map the laws, regulatory guidance, and contract terms that apply to your organization, and obtain legal advice where the position is unclear. Then use a proportionate policy. Low-risk domestic suppliers may need basic entity and payment checks, while high-value, cross-border, regulated, or unusually structured suppliers may need full ownership verification, screening, and ongoing monitoring.

How Shufti supports vendor KYC and ongoing supplier checks

Manually checking thousands of suppliers across several jurisdictions can create slow onboarding and inconsistent evidence. Shufti’s business verification service helps teams confirm companies against official registries, identify directors and beneficial owners, map ownership chains, and apply jurisdiction-specific ownership thresholds. Registry data, documents, and UBO outcomes can then be consolidated into one audit-ready company report.

Shufti’s database covers more than 300 million companies, and it actively processes 240+ regions. Coverage and match quality still vary by registry and jurisdiction, so document-led fallbacks and human review remain important when authoritative data is limited. Teams can also connect business verification with AML screening and ongoing monitoring to keep higher-risk supplier records up to date.
