What is the KYB Process? B2B Requirements, Steps, and Compliance Explained
If you plan to partner up with another business and sign a six-figure contract, you need to first ask yourself: How well do I actually know this company? Behind a polished website and a professional LinkedIn page, there could be a legitimate enterprise or a complex web of shell companies designed to hide something darker.
To make sure you’re dealing with a clean and legitimate partner, you need Know Your Business (KYB) – a regulatory and risk management process that helps companies verify the legitimacy of other businesses before working with them.
In this article, we’re breaking down what the KYB process is, why it’s non-negotiable in today’s economy, and how you can implement it without losing your peace of mind or operational speed.
What Is Know Your Business (KYB)?
Know Your Business (KYB) is a due diligence process used by organizations to verify the identity and legitimacy of other businesses they intend to work with. Similar to a deep-background check for companies, KYB is set to verify that a business exists on paper.
KYB is about confirming a company’s legal status, identifying who truly owns or controls it, i.e. who the Ultimate Beneficial Owners (UBOs) are, and assessing whether that business poses a risk of financial crime, such as money laundering or fraud.
EXAMPLE: Let’s say you run a logistics company. A new firm, called QuickShip Inc., wants to partner with you. After a basic search, you find out that they have a legit-looking website. But a KYB check reveals that QuickShip Inc. isn’t registered in any national database, its listed office is a vacant lot on a dodgy street, and its owner is actually a shell company based in a high-risk jurisdiction. That’s how a KYB check can save you from a massive legal and financial headache.
As you can see, KYB is closely tied to Anti-Money Laundering (AML) and Counter-Terrorist Financing (CTF) regulations. That’s why governments worldwide require financial institutions and certain regulated businesses to verify the identity of corporate clients before doing business with them.
Why is KYB Required for B2B Companies?
KYB is often viewed as an extension of Know Your Customer (KYC). The reason behind it is that KYB is a much younger regulation. While KYC procedures were set for decades, businesses were not subjected to the same screening until recently, allowing fraudsters to exploit companies for illicit activities.
In Europe, things changed in 2017 when regulators corrected the legal blind spot by specifying KYB in the 4th AML Directive. The updated regulation came a year after the US Financial Crimes Enforcement Network (FinCEN) included KYB rules in Customer Due Diligence requirements for financial institutions.
In the B2B sector, the participants are entities that can move large sums of money, which attracts fraudsters and money launderers. The United Nations Office on Drugs and Crime (UNODC) has estimated that between 2% and 5% of global GDP is laundered each year, which amounts to almost $2 trillion. Moreover, a recent survey showed that 79% of organizations were victims of payment fraud attacks or attempts.
Why Compliance Matters for Businesses
First of all, knowing what’s behind a company’s corporate clients ensures authenticity and protection against corrupt or fraudulent business practices, such as money laundering and terrorist financing.
Second, it’slegal safety. Regulatory bodies like the Financial Action Task Force (FATF), the EU’s AMLDs, the US Bank Secrecy Act (BSA) set global standards that most countries include in their laws. So, ignoring these can lead to “cease and desist” orders or astronomical fines. For example, back in 2024, TD Bank agreed to pay a combined total of $3.09 billion to US authorities for money-laundering activities that occurred as a result of failing to maintain an adequate AML program.
Third, KYB compliance protects business reputation. Nothing kills a brand faster than being the “facilitator” for a sanctioned entity or a criminal network. More so, partnering with a high-risk or fraudulent entity can lead to frozen assets, regulatory investigations, and loss of customer trust.
Finally, KYB ensures financial stability by preventing Business Email Compromise (BEC) and vendor impersonation – two of the leading causes of corporate financial loss today.
Who Is Required to Perform KYB?
The KYB process is necessary for more than just the financial services industry. According to the EU’s 5th AML directive, the following organizations, businesses, and individuals are subjected to the regulation:
- credit institutions
- financial institutions
- online banking
- auditors
- asset managers
- external accountants
- tax advisors
- cryptocurrency marketplaces
- notaries
- trusts
- estate agents
- gambling services
- other regulated B2B sectors
While not required by law, companies in unregulated industries also perform KYB checks. The reason is that regulatory checks on business partners can secure a company’s reputation and protect it from fraud and misuse of assets.
Key Steps in the KYB Process
Navigating a KYB check is a multi-step process designed to uncover the truth about a company’s registration, ownership structure, directors, and risk status.
STEP 1. Company Identity Verification
At this step of the KYB process, you collect the basic data about the company to prove that it exists. Typically, you would check official registries for the following info:
- Company name
- Registration number
- Registered address
- Date of incorporation
- Legal form
This step is necessary because sometimes fraudsters create fake or cloned company identities. So, verification against company registries ensures that an entity is real.
STEP 2. Legal Entity Validation
At this stage, you verify the company’s current status: is it “active”, “dissolved”, “suspended”, or “in liquidation”? Apart from checking a company’s legal status, you also need to confirm:
- Its authorized representatives
- Directors or board members
By performing this step, you’re able to identify unauthorized individuals who may be acting on behalf of a company.
STEP 3. Ultimate Beneficial Owner (UBO) Identification
This is the “Who’s actually in charge?” step. Money launderers often hide behind “nested” companies: Company A is owned by Company B, which is owned by Company C. The goal of this step is to identify the natural person or the UBO who owns or controls at least 25% of the business.
Identifying UBOs is critical to preventing misuse of legal entities, as shell companies often hide true owners behind multiple layers.
STEP 4. Sanctions and PEP Screening
Once you have the names of the company and its owners (UBOs), you run them against global lists. First you check whether or not they are on the sanctions lists, Politically Exposed Persons (PEP) lists, adverse media sources. Are they blocked from doing business by the UN, EU, or US? Are they a government official? Are they involved in some incriminating stories?
This is an important step that allows you to identify sanctioned individuals you don’t want to start business with because it may result in your assets being frozen and penalties imposed.
STEP 5. Risk Assessment and Categorization
Finally, based on the data you’ve collected, you can now assign a risk score in accordance with these criteria: industry, geography, ownership complexity, transaction type, and regulatory exposure. The higher the risk, the more checks are required, in particular Enhanced Due Diligence (EDD). For example, a low risk company may be a local software firm with a clear 10-year history. And a high risk company could be a new offshore firm in a jurisdiction known for tax evasion.
STEP 6. Ongoing Monitoring
KYB is not a one-off activity, as a company’s status may change with time. Thus, a company that is “clean” today might be sold to a sanctioned entity/individual tomorrow. Ongoing monitoring ensures you get an alert the moment something changes: ownership structure, sanctions lists get updated, or companies dissolve or become insolvent.
Common Challenges in the KYB Process
KYB is not an easy process, and compliance teams face quite a few speed bumps while verifying potential business partners. Let’s analyze the most pressing ones.
Complex Ownership Structures
One of the biggest obstacles in KYB is identifying the true ultimate beneficial owner. Many companies are owned by other companies, sometimes across multiple jurisdictions. Bad actors use opaque ownership structures to obscure beneficial ownership in their corruption or money laundering schemes.
EXAMPLE: A Polish FinTech wants to onboard a UK-based wholesale distributor. It turns out that this UK company is owned by a holding entity in Cyprus. And that Cypriot entity is owned by a trust registered in the British Virgin Islands. The trust lists a corporate trustee instead of individuals.
This shows that tracing ownership through each layer requires registry access, legal interpretation, and sometimes additional documentation from the client. For compliance teams, unraveling these structures manually can take hours or days for each client.
Cross-Border Verification Barriers
Every country has its own registry: some are digital and easy to access, while others require a physical visit to a shady office in another time zone.
The problem is that corporate registry transparency varies significantly worldwide. Some countries provide free, structured, digital registry access. But it’s a completely different story with other countries that may demand:
- Paid requests
- Local language filings
- Manual document retrieval
- Physical submissions
EXAMPLE: A European payment institution onboarding a logistics company registered in Southeast Asia may struggle to access up-to-date registry data, confirm director legitimacy, and verify active company status.
When data isn’t standardized or easily accessible, compliance teams rely on additional documentation, which, in turn, increases onboarding time and friction.
Registry Inconsistencies and Data Quality Issues
Information in government registries is notoriously prone to being outdated or containing typos. Moreover, it may not be digitized and structured for automated analysis. To make matters worse, different jurisdictions use different formats for shareholder disclosure, ownership thresholds, director reporting, and company status classification.
EXAMPLE: One country may list shareholders by percentage, another may only list the number of shares, and yet another may not publish ownership publicly at all.
This inconsistency forces compliance teams to interpret and standardize data manually, which increases the risk of error.
Data Fragmentation Across Multiple Sources
The KYB process requires combining information from corporate registries, sanctions lists, PEP databases, adverse media screening, and internal transaction data. So, having to log into five different databases to verify one company is a massive drain on productivity.
When these systems aren’t integrated, teams switch between platforms, export spreadsheets, and manually reconcile information. All this leads to increased onboarding time, higher operational costs, and a greater chance of oversight. When workflows are fragmented, they become bottlenecks.
Rapidly Changing Sanctions and Regulatory Requirements
Sanctions regimes and regulatory rules evolve quickly – what was compliant six months ago might be a violation today.
Governments regularly update sanctions lists, restrict new jurisdictions, define new ownership thresholds. If sanctions monitoring is periodic instead of continuous, companies risk unknowingly maintaining business relationships with newly sanctioned entities. On top of that, anti-money laundering regulations continue to tighten globally, particularly around beneficial ownership transparency.
Balancing Regulatory Compliance with Customer Experience
B2B clients expect fast onboarding. If the KYB processes take days instead of hours, repeated document requests, excessive back-and-forth communication, it can create friction or even lost business opportunities.
So, the challenge is to balance strict regulatory demands with operational efficiency and client satisfaction. Too little diligence increases regulatory risk, but too much friction increases churn risk.
How Companies Implement the KYB Process in Practice
To successfully implement KYB verification, you need a workflow that coordinates the actions of compliance, risk, legal, and operations teams. Here is what a KYB process should include:
- Define risk policies, UBO thresholds, high-risk jurisdictions, required documentation
- Collect and verify data, get access to official registries, map ownership structures
- Screen sanctions lists, conduct risk assessment
- Document and store evidence
- Monitor continuously: ownership changes, sanctions updates, adverse media mentions
Modern companies are ditching manual searches and moving toward automated KYB solutions. This involves integrating a KYB API into your onboarding flow. When a new business signs up, the system automatically pulls their registration data, maps out the UBOs, and runs the sanctions checks in seconds.
For those looking to streamline this, exploring business verification services is the most practical way to turn compliance into a competitive advantage.
Manual vs. Automated KYB Process
Choosing between manual and automated KYB is like choosing between a horse-drawn carriage and a car. Both will get you there, but one is much better for business growth. Here’s how the two approaches compare:
| Factor | Manual KYB | Automated KYB |
| Speed | Slower; registry checks are done individually | Faster; integrated registry access |
| Scalability | Limited by team size | Easily scales with onboarding volume |
| Accuracy | Prone to human error | Standardized, rule-based validation |
| Ownership mapping | Difficult for complex structures | Automated ownership visualization |
| Sanctions screening | Periodic, manual checks | Real-time screening & alerts |
| Ongoing monitoring | Often reactive | Continuous monitoring |
| Audit trail | Document-heavy, manual storage | Automated audit logs |
Businesses cannot afford blind trust. KYB ensures that when you say “yes” to a new partnership, you do so with clarity and confidence.
Understanding the entire process – from company verification to ongoing monitoring – empowers organizations to protect themselves, their customers, and the financial system as a whole.
