What is KYB? A Guide for African Fintechs

KYB (Know Your Business) is the process of verifying that a business customer or partner is real, legally registered, and who it claims to be. It is the company-level equivalent of KYC: where KYC confirms an individual's identity, KYB confirms a legal entity's existence, registration status, ownership, and standing before you onboard it, lend to it, settle payments to it, or list it on your platform.

For African fintechs, KYB has moved from a back-office formality to a frontline risk control. Regulators expect it, fraud teams depend on it, and your underwriting and payments rails break down without it. This guide explains what KYB is, how it differs from KYC, the core checks involved, why it is uniquely hard across African markets, and how teams move from slow manual lookups to automated verification through a business verification API Africa can actually rely on.

KYB vs KYC: what's the difference?

KYC (Know Your Customer) verifies a person: their name, date of birth, ID document, and address. KYB (Know Your Business) verifies an entity: a registered company, partnership, or sole proprietorship. The two are related but not interchangeable. When a marketplace onboards a merchant, a lender underwrites an SME, or a payments processor signs a new corporate account, the customer is a business, so KYB is the primary obligation.

Crucially, KYB usually contains KYC. To verify a business you must verify the humans behind it: its directors and its ultimate beneficial owners (UBOs). A KYB process that stops at the registration certificate and never identifies who actually controls the company is incomplete, and in most regulated contexts, non-compliant. Think of KYB as the wrapper and KYC as a step performed on each key individual inside it.

Why KYB matters for African fintechs

Africa's fintech boom runs on business-to-business trust at scale. The use cases that depend on solid KYB are exactly the ones driving growth:

• Merchant onboarding for payment gateways and marketplaces, where a fake or shell merchant becomes a fraud and chargeback liability the moment it goes live.
• SME and embedded lending, where you cannot price risk on a business that may not legally exist or may be dissolved.
• Payments and payouts, where settling funds to an unverified corporate account is both a fraud vector and an AML exposure.
• Marketplaces and B2B platforms, where buyer and seller trust is your product, and a single fraudulent counterparty erodes it.
• Supplier and vendor due diligence, where you need to know that the company you are paying is real before money leaves the building.

Underpinning all of this is AML/CFT (anti-money-laundering and counter-financing of terrorism) obligation. Regulators such as the Central Bank of Nigeria (CBN) expect fintechs to know the businesses they serve, screen them against sanctions and PEP lists, and identify beneficial owners, reflecting the global push for beneficial-ownership registers. Weak KYB is how shell companies launder funds, how fraud rings open merchant accounts, and how a fintech ends up explaining itself to a regulator. Strong KYB is a competitive advantage: it lets you onboard good businesses faster while keeping bad ones out.

The core KYB checks

A complete KYB check is a stack of verifications, not a single lookup. The core components are:

• Registration / RC number, confirm the company is registered with the relevant registry (in Nigeria, the CAC RC or BN number) and that the number resolves to a real entity.
• Legal name and entity type, confirm the exact registered name and structure (limited company, business name, etc.), not just the trading name on the website.
• Status, confirm the company is active, not dissolved, struck off, or dormant.
• Incorporation date and history, a company registered last week behaves differently in risk models than one trading for ten years.
• Tax identity (TIN), confirm the entity's tax registration where available; you can verify a TIN as part of the check.
• Directors, identify the people legally responsible for the company.
• Ultimate beneficial owners (UBOs), identify the natural persons who ultimately own or control the entity, typically above a 25% threshold.
• Sanctions and PEP screening, screen the entity and its key people against sanctions lists and politically-exposed-person databases.
• Registered address, confirm a verifiable place of business rather than an empty mailbox.

The first few checks establish that the entity exists and is in good standing. The director, UBO, and screening layers establish who is behind it and whether they carry risk. Both halves matter; skipping the ownership layer is the most common KYB gap.

Why KYB is hard in Africa

KYB tooling built for the US or EU assumes clean, queryable, machine-readable registries. Across much of Africa, that assumption breaks. Three problems recur:

Fragmented registries. Every country runs its own corporate registry with its own format, access model, and identifiers, Nigeria's CAC, Senegal's RCCM, and dozens more, each different. A pan-African fintech that wants one onboarding flow has to reconcile a dozen incompatible sources. There is no single front door.

Paywalled and gated ownership data. Basic registration may be checkable, but the data you most need for AML, directors, shareholders, and beneficial owners, often sits behind manual requests, fees, or licensed access. Teams either skip it or burn hours per company retrieving it.

Stale data. Aggregators help, but coverage and freshness are uneven. OpenCorporates, the largest open company database, is widely used as a starting point, yet its Africa coverage is notoriously stale, with records that lag the official registries by years or omit entire jurisdictions. Verifying a live business against a snapshot from years ago produces false negatives on real companies and false confidence on dissolved ones. This staleness gap is the central problem KYB in Africa has to solve.

Manual KYB vs automated KYB via API

Many African fintechs still do KYB by hand: an ops analyst opens the registry portal, searches the name, screenshots the certificate, emails the merchant for incorporation documents, and files it all in a shared drive. This works at ten companies a week. It collapses at a thousand. It is slow, inconsistent between analysts, hard to audit, and impossible to re-verify on a schedule.

Automated KYB replaces that workflow with API calls. You send a company name or registration number, and you get back a structured, sourced result in seconds: legal name, status, RC number, incorporation date, type, TIN, and, via licensed sources, directors, shareholders, and beneficial owners. The same call can run in real time at signup, in batch across your existing book, or on a recurring basis to catch a customer that has since been dissolved. The output is consistent, timestamped, and auditable, which is exactly what a compliance review or a regulator wants to see.

The practical bar: an API that returns a real, sourced answer for every legitimate company, rather than a blank for anything outside a stale cache. Live fallthrough to the official registry means real companies always resolve, even brand-new or obscure ones.

What good KYB data looks like

Not all KYB data is equal. When evaluating providers, look past the demo and interrogate the data itself. What to look for in a KYB provider:

• Provenance on every field, which source (CAC, RCCM, etc.) the data came from, so you can stand behind it in an audit.
• Freshness / last-verified date, when each record was last confirmed against the source, not just when it was first scraped.
• Confidence indicators, an honest signal of how strong a match is, so your team can route low-confidence cases to manual review.
• Live fallthrough, real companies resolve to the official registry instead of returning empty when they are not in a cached set.
• Ownership depth on demand, directors, shareholders, and beneficial owners available via licensed sources, not just the registration certificate.
• Multi-market coverage, one integration spanning the registries you actually serve, with a clear roadmap for the next.
• The right API surface, search, company lookup, a verify (KYB check) endpoint, and bulk-verify for processing your existing book.

Fylings is built around this standard: free public company pages across African registries, with provenance, last-verified, and confidence on every record, plus a paid API and verification reports for KYB teams. You can search a company free at fylings.com to see the data before you integrate, browse the Nigeria hub for CAC coverage, and use the same provenance-first records through the API.

How to run KYB in practice

A workable KYB program for an African fintech looks like this. First, define your risk tiers, a low-value merchant and a large lending counterparty do not need identical depth. Second, at onboarding, run the entity checks (registration, status, name, type, TIN) automatically via API so good businesses pass in seconds. Third, for higher-risk tiers, pull directors and beneficial owners and run sanctions/PEP screening on them. Fourth, log every result with its source and date for your audit trail. Fifth, re-verify periodically, businesses dissolve, change directors, and change control, and a check from a year ago is not a check today.

For supplier and vendor relationships, the same logic applies before money moves; our guide to supplier due diligence walks through the entity-level checks for paying a Nigerian company you have not worked with before.

Bring reliable KYB to your fintech

KYB is no longer optional for African fintechs onboarding merchants, lending to SMEs, or moving money between businesses. The challenge has never been whether to do it, it is getting trustworthy, fresh, sourced data across fragmented registries without drowning your ops team in manual lookups.

That is what the Fylings API is built for: KYB checks across African registries with provenance, freshness, and confidence on every record, live fallthrough so real companies always resolve, and search, lookup, verify, and bulk-verify endpoints your team can integrate in an afternoon.
