KYC and KYB are two important parts of compliance. They are closely related, but they are not the same. KYC stands for Know Your Customer. KYB stands for Know Your Business. KYC is used to verify individuals. KYB is used to verify companies. Both processes help organisations understand who they are dealing with, what risks may exist, and whether further review is needed.
For compliance teams, the difference matters. A business may onboard an individual customer, a company, a merchant, a corporate client, a policyholder, a partner, or a corporate service client. Each relationship requires a different level of review. That is why KYC and KYB should not be treated as isolated checks. They should work together as part of one connected compliance workflow.
Quick Answer: KYC vs KYB
KYC verifies the identity and risk profile of an individual customer. KYB verifies the identity, ownership structure and risk profile of a business customer.
| KYC | KYB |
|---|---|
| Verifies an individual's identity and risk profile | Verifies a business's identity, ownership structure and risk profile |
The simple way to understand it: KYC asks: Who is this person? KYB asks: What is this business, and who controls it?
Why KYC and KYB Matter
KYC and KYB matter because businesses need to understand risk before starting or continuing a relationship. This is especially important for regulated or risk-sensitive industries. These include: Banking; Payments; Insurance; FinTech; Corporate service providers; Wealth management; Lending; Digital platforms; B2B marketplaces.
FATF says its Recommendations provide a comprehensive framework to help countries tackle illicit financial flows through laws, regulations and operational measures. These include preventive measures, beneficial ownership transparency and international cooperation.
For compliance teams, this means identity checks alone are not enough. Teams also need to understand: The customer; The business relationship; The ownership structure; The risk profile; The screening results; The decision trail; The ongoing monitoring requirement.
This is where KYC and KYB become part of a wider compliance workflow.
What Is KYC?
KYC stands for Know Your Customer. It is the process of identifying, verifying and assessing an individual customer. KYC helps businesses confirm that a person is who they claim to be. It also helps compliance teams understand whether the person presents any risk.
Common KYC Checks
- Identity verification
- ID document check
- Proof of address
- PEP screening
- Sanctions screening
- Adverse media
- Source of funds
KYC is commonly used when onboarding individual customers. For example: A bank opening a personal account; A payment firm onboarding a user; An insurer verifying a policyholder; A wealth manager reviewing an investor; A platform verifying a seller or user.
However, KYC is also used inside KYB. When a company is onboarded, the compliance team may still need to run KYC checks on directors, shareholders and beneficial owners.
What Is KYB?
KYB stands for Know Your Business. It is the process of verifying a company or legal entity. KYB helps compliance teams understand whether a business is legitimate, properly registered and suitable for the relationship. It also helps identify the people who own or control the business.
Common KYB Checks
- Business registration verification
- Incorporation documents
- Business activity
- Directors
- Shareholders
- Ultimate beneficial owners
- Entity screening
KYB is common in B2B compliance. For example: A payment company onboarding a merchant; A bank opening a corporate account; A corporate service provider onboarding a new company; A SaaS provider reviewing a high-risk enterprise client; An insurer reviewing a corporate policyholder; A marketplace verifying business sellers.
KYB gives the compliance team a clearer view of the business relationship. It also helps identify whether further KYC checks are needed on people linked to the company.
KYC vs KYB Comparison Table
| Dimension | KYC | KYB |
|---|---|---|
| Focus | The person | The company and its people |
| What it verifies | Individual identity and person-level risk | Company information, ownership structure and entity-level risk |
| Typical documents | Passport, national ID, proof of address, source of funds | Business profile, incorporation records, register of directors, ownership charts |
| Screening scope | PEP, sanctions and adverse media on the individual | Entity screening plus KYC on directors, shareholders and UBOs |
| Typically used when | Onboarding an individual customer | Onboarding a business or legal entity |
| Risk view | Is this person who they claim to be, and do they create risk? | Is this business legitimate, and who owns and controls it? |
The main difference is scope. KYC focuses on the person. KYB focuses on the business and the people behind it.
Why Businesses Need Both KYC and KYB
Many business relationships involve both individuals and companies. For example, a corporate client may look simple at first. However, the company may have: Multiple directors; Several shareholders; Corporate shareholders; Foreign ownership; Nominee arrangements; Ultimate beneficial owners; Complex control rights; Related entities.
In this case, KYB alone is not enough. The compliance team also needs KYC checks on the people behind the business.
Example: Corporate Client Review
| Relationship | Check applied |
|---|---|
| The corporate client (company) | KYB on the company — registration, ownership structure and entity risk |
| Each director | KYC on the individual |
| Each shareholder | KYC on the individual |
| Each ultimate beneficial owner (UBO) | KYC on the individual |
This is why KYC and KYB should not sit in separate workflows. They should connect. A business risk profile is incomplete if the people behind the business are not understood.
When KYC Applies
KYC usually applies when an organisation deals with an individual. This could be a direct customer or a person connected to a business relationship.
Common KYC Use Cases
- A bank opening a personal account
- A payment firm onboarding a user
- An insurer verifying a policyholder
- A wealth manager reviewing an investor
- A platform verifying a seller or user
KYC helps answer three key questions: Is this person real?; Is this person who they claim to be?; Does this person create compliance risk? If the answer is unclear, further review may be needed.
When KYB Applies
KYB applies when an organisation deals with a business or legal entity. This is common in B2B environments.
Common KYB Use Cases
- A payment company onboarding a merchant
- A bank opening a corporate account
- A corporate service provider onboarding a new company
- A SaaS provider reviewing a high-risk enterprise client
- An insurer reviewing a corporate policyholder
- A marketplace verifying business sellers
KYB helps answer five key questions: Is this business properly registered?; What does the business do?; Who owns the business?; Who controls the business?; Does the business present higher risk? KYB becomes more complex when ownership structures are layered or cross-border. That is why beneficial ownership review is so important.
Beneficial Ownership: Where KYC and KYB Meet
Beneficial ownership is where KYC and KYB connect. A company is a legal entity. However, companies are ultimately owned or controlled by people. KYB identifies the business. KYC verifies the people behind the business.
FATF includes transparency and beneficial ownership of legal persons and arrangements as one of the seven areas within its 40 Recommendations. This is important because a company structure may hide the true person in control.
Beneficial Ownership Review Example
| Step | What happens |
|---|---|
| 1. Company A | Run KYB on Company A. Its shareholder register shows it is owned by Company B. |
| 2. Company B | Company B is incorporated in another jurisdiction. Trace the ownership through to the next layer. |
| 3. Natural-person UBO | Identify the natural person who ultimately owns or controls the structure. |
| 4. KYC on the UBO | Run KYC on the ultimate beneficial owner — identity, PEP, sanctions and adverse media. |
This is why companies need both checks. KYB reviews the business structure. KYC reviews the individuals behind the structure. Together, they help compliance teams understand the full risk picture.
Common KYC and KYB Documents
The documents required depend on the customer type, jurisdiction and risk level. However, most workflows include a mix of identity, company and ownership records.
KYC Documents
- Passport
- National ID card
- Proof of address
- Employment information
- Source of funds documents
KYB Documents
- Business profile
- Incorporation records
- Register of directors
- Shareholder records
- Beneficial ownership declarations
- Ownership charts
A good workflow should connect these documents to the right client record. Otherwise, teams may spend too much time searching across folders, emails and spreadsheets.
Common KYC and KYB Challenges
KYC and KYB can become difficult when the process is too manual. The compliance team may understand the requirements. However, the workflow may not support the work properly.
Common Challenges
- Manual data collection
- Documents scattered across folders, email and spreadsheets
- KYC and KYB handled in disconnected tools
- Screening-alert review pressure
- Inconsistent risk scoring
- Weak audit trail
These are not just compliance issues. They are operational issues. A team can do the right checks and still struggle if the workflow is weak.
Manual vs Workflow-Led KYC and KYB
| Manual | Workflow-led |
|---|---|
| Scattered information across tools | One connected client view |
| Unclear ownership | Clear ownership structure |
| Screenshots as evidence | A captured decision trail |
| Inconsistent risk scoring | Consistent risk scoring |
| Hard to audit | Easy to audit |
This is the shift modern compliance teams need. KYC and KYB should not be treated as isolated checks. They should operate as connected workflows.
How KYC and KYB Support a Risk-Based Approach
Not every customer or business relationship carries the same level of risk. A risk-based approach helps compliance teams focus more attention where risk is higher.
FATF describes the risk-based approach as the cornerstone of its Recommendations. It explains that countries should identify and understand money laundering and terrorist financing risks so resources can be prioritised in higher-risk areas.
For businesses, the same logic applies at operational level. A low-risk individual may need standard KYC. A complex corporate structure may need deeper KYB, UBO review and enhanced due diligence.
Risk-Based Review Example
| Relationship | Level of review |
|---|---|
| Low-risk individual | Standard KYC |
| Complex corporate structure | Deeper KYB, UBO review and enhanced due diligence |
Risk-based compliance is not about doing less work. It is about applying the right level of review to the right risk.
KYC and KYB Across Different Industries
KYC and KYB appear across many industries. However, the operational challenge differs by sector.
Industry Examples
| Industry | KYC / KYB focus |
|---|---|
| Banking | KYC on personal account holders; KYB on corporate accounts |
| Payments | KYC on users; KYB on merchants being onboarded |
| Insurance | KYC on policyholders; KYB on corporate policyholders |
| Fintech | KYC on individual users; KYB on business customers |
| Corporate service providers | KYB on new companies; KYC on directors and beneficial owners |
| Wealth management | KYC on investors; KYB where investment entities are involved |
| B2B marketplace | KYB on business sellers; KYC on the people behind them |
The common theme is visibility. Compliance teams need to understand both the customer and the wider relationship.

Why KYC and KYB Should Share One Source of Truth
Many compliance teams still manage KYC and KYB separately. That creates blind spots. For example: A company may pass KYB, but its beneficial owner may trigger PEP screening; A director may appear low risk, but the company may operate in a higher-risk sector; A business may be properly registered, but its ownership structure may be unclear; A customer may pass onboarding, but later adverse media may change the risk profile.
These risks are easier to manage when KYC and KYB information sits in one connected workflow.
One Source of Truth for KYC and KYB
- Customer profile
- Company profile
- Ownership / UBO review
- Screening results
- Risk score
- Case notes
- Approval records
This is where KYC and KYB become more than verification steps. They become part of compliance operations.

How does WIDTH help with KYC and KYB?
WIDTH helps compliance teams connect KYC, KYB, screening, risk scoring, case management and audit-ready records into one workflow-led compliance platform.
KYC and KYB Work Best When They Are Connected
KYC and KYB are different, but they work best together. KYC helps organisations understand individuals. KYB helps organisations understand businesses. For many compliance teams, both are needed to understand the full relationship. A company may look low risk on paper. However, its directors, shareholders, beneficial owners, business activity or adverse media profile may tell a different story. That is why KYC and KYB should not sit in separate spreadsheets, folders or disconnected tools. They should operate as one connected workflow. This gives compliance teams better visibility, stronger accountability and clearer audit evidence. WIDTH supports this approach by helping organisations connect customer profiles, company profiles, ownership reviews, screening results, risk scoring, case management and approval records in one platform. For teams that want to move from fragmented checks to connected compliance operations, KYC and KYB are not just onboarding steps. They are the foundation for better risk intelligence.
