Digital Banking for Small Businesses: Nomba Expands in Nigeria

Nigerian fintech company Nomba is expanding its focus on small-business banking through Nombank, its banking subsidiary, as fintech companies increasingly combine digital payments with banking and credit services for merchants.

Nombank is seeking a larger share of Nigeria’s small-business banking market by using transaction information generated through Nomba’s payments platform to assess businesses and develop financial products around their activity. Recent reporting on the strategy said the approach is intended to serve businesses that may struggle to obtain conventional bank credit.,

The move reflects a broader shift in Nigeria’s fintech sector, where payment companies are increasingly moving beyond transaction processing into business accounts, transfers, credit and other financial services.

From payments to business banking

Nomba began primarily as a payments-focused fintech, providing tools that allow businesses to accept and manage payments.

Its current business platform includes business accounts, payment links, invoicing and other financial-management tools. Nomba says its banking services are provided by Nombank Microfinance Bank, which is licensed by the Central Bank of Nigeria and has deposits insured by the Nigeria Deposit Insurance Corporation.

The expansion into banking gives the company a broader relationship with merchants.

Instead of simply processing a customer’s payment and sending the proceeds to a bank account, a fintech with banking infrastructure can potentially provide more of the financial services a business needs within the same ecosystem.

For small businesses, that can mean fewer separate systems for managing money.

Using transaction data to understand businesses

One of the central elements of Nombank’s strategy is the use of merchant transaction data.

Traditional lenders may require businesses to provide collateral, audited financial statements and extensive documentation before approving credit.

Those requirements can be difficult for smaller businesses, particularly businesses that have operated informally or have limited financial records.

Nombank’s approach is to use transaction activity from Nomba’s payments platform as part of its assessment of a business’s financial behaviour. PUNCH reported that the bank intends to use this information to assess the financial health of merchants and tailor lending decisions to their business activity.

The approach does not eliminate the need for credit assessment or regulatory requirements.

Instead, transaction data can provide another source of information about how a business receives money, the volume of its transactions and patterns in its operations.

Why SME banking is attracting fintech companies

Small and medium-sized enterprises make up a large part of Nigeria’s business economy, but access to formal finance remains a challenge for many operators.

For a small retailer, restaurant, online seller or service provider, the difference between having access to working capital and being unable to obtain it can affect inventory, staffing and expansion.

This creates a potential market for financial products designed around actual business activity.

A merchant who receives regular payments through a digital platform may generate useful financial information even when the business does not have the traditional documentation expected by a conventional lender.

This is one reason fintech companies have increasingly connected payments data with other financial services.

Business accounts are becoming part of fintech platforms

The shift is not limited to Nomba.

Paystack, another major Nigerian fintech, launched Paystack Microfinance Bank in January 2026, expanding its activities beyond payment processing into broader financial services. The company said the microfinance bank would operate independently from Paystack Payments Limited, with its own licence, governance structure and product roadmap.

Paystack’s current services for Nigerian registered businesses also include PT accounts, which are bank accounts created in partnership with a Nigerian bank to facilitate transfers from a business’s Paystack dashboard. Paystack says the accounts can currently be powered through Titan Trust Bank or Paystack Microfinance Bank.

The development illustrates how the boundary between fintech payment services and digital banking is becoming less distinct.

Payment companies can use their existing relationships with merchants as a starting point for additional financial products.

Digital banking can simplify business operations

For a small-business owner, the value of digital banking is not limited to having a bank account on a phone.

A well-designed business platform can bring several daily activities together.

These can include receiving customer payments, making transfers, paying suppliers, monitoring cash flow, managing invoices and accessing financial records.

Nomba currently promotes business accounts that allow merchants to receive, send and manage business money through its platform.

Paystack similarly provides businesses with tools for payments, transfers, dedicated virtual accounts and other financial operations.

For entrepreneurs, having these functions connected can reduce the need to move between multiple platforms.

Regulation remains important

The expansion of fintech companies into banking and credit does not mean they operate outside Nigeria’s financial regulatory system.

Financial institutions and payment companies must comply with rules covering areas such as customer identification, fraud prevention, consumer protection and transaction monitoring.

The Central Bank of Nigeria has also been updating the regulatory environment surrounding digital financial services.

In 2026, the CBN introduced new requirements covering areas including online account security, fraud monitoring and identity verification. The bank said financial institutions must deploy real-time enterprise fraud-monitoring systems and strengthen identity verification for online account opening and account reactivation, with the new standards taking effect from July 1, 2026.

The CBN has also established a regulatory sandbox where fintechs, financial institutions and technology companies can test innovative financial products and business models under regulatory supervision.

These measures reflect the balance regulators are attempting to maintain between financial innovation and protection of customers and the financial system.

Data creates opportunities and responsibilities

Using transaction data to support financial services can make it easier for lenders to understand businesses that might otherwise have limited formal financial information.

But it also makes data protection and responsible financial decision-making important.

A fintech that holds detailed information about a merchant’s transactions has access to commercially sensitive information.

Businesses therefore need to understand how their data is collected, used and protected.

Credit decisions also need appropriate safeguards.

Transaction volume alone does not establish whether a business can repay a loan. A lender may need to consider other factors, including expenses, existing obligations, cash-flow patterns and the purpose of the borrowing.

Competition is increasing

Nomba’s banking strategy is developing within a fintech market where several companies are competing for business customers.

Paystack has expanded into microfinance banking, while other fintechs and financial institutions are developing digital tools aimed at SMEs.

Ecobank Nigeria launched the Ecobank Business App in February 2026, positioning it as a digital banking platform for small and medium-sized businesses. The bank said the platform allows businesses to manage payments, monitor transactions, oversee cash flow and handle daily financial operations through mobile devices.

The competition means small businesses are gaining more choices.

For fintech companies, however, providing an attractive app is only one part of the challenge.

They must also maintain reliable payment infrastructure, protect customer funds and data, meet regulatory requirements and provide useful financial products.

The infrastructure challenge

Digital finance depends heavily on reliable technology.

Recent events in Nigeria have demonstrated how quickly demand can put pressure on fintech infrastructure.

During the launch of Dangote Petroleum Refinery’s $1.6 billion initial public offering in September 2026, several Nigerian digital investment platforms experienced outages as retail investor traffic surged. Reuters reported that Bamboo experienced a tenfold increase in traffic within half an hour, while other platforms also experienced disruptions.

Although the incident involved investment platforms rather than SME banking, it illustrates a wider issue for digital financial services: rapid growth requires infrastructure capable of handling sudden increases in demand.

Reliability therefore becomes part of the customer experience.

What small businesses should look for

As more fintech companies offer business banking services, entrepreneurs should compare products carefully.

Important questions include:

• Who is the licensed financial institution behind the service?
• What fees apply to transfers and other transactions?
• Are deposits covered by applicable deposit insurance?
• What transaction limits apply?
• How quickly can businesses access their funds?
• What support is available when transactions fail?
• What lending products are available and at what cost?
• How is business data used?
• What security measures protect the account?

The convenience of a digital platform should not replace basic financial due diligence.

What comes next for Nigerian fintech

The expansion of fintech companies into digital banking is changing the way small businesses interact with financial services.

For companies such as Nomba, payments can provide a foundation for additional services including business accounts and credit.

For merchants, the potential benefit is having more financial services built around the actual way their businesses operate.

But the growth of digital banking will depend on more than new products.

Fintech companies will need reliable infrastructure, effective risk management, strong customer support and compliance with financial regulations.

The CBN’s Nigeria Payments System Vision 2028 also points towards a broader transformation of the country’s payment ecosystem, with the central bank describing the strategy as a framework for a more inclusive and innovation-driven digital economy.

For Nigerian small businesses, the practical significance is that banking and payments are increasingly being brought together on digital platforms.

The next stage will be whether these services can provide affordable, reliable and useful financial tools for businesses as they grow.
