   • Dynamic credit scoring (using alternative data like mobile money history, utility payments, and social media activity to assess creditworthiness for underserved populations). This allows fintechs to offer more inclusive financial products.
   • Personalized financial advice and product recommendations, improving customer engagement and loyalty.
3. API-First Architecture is Non-Negotiable
   • Fintechs need CBS that seamlessly connects to a wide array of external services and platforms, fostering an open banking ecosystem.
   • Local payment gateways (Flutterwave, Paystack, Remita) for diverse payment options and collection methods.
   • Identity systems (NIN, BVN via NIBSS) for robust KYC and customer verification, crucial for combating fraud and complying with regulatory requirements.
   • Credit bureaus (CRC Credit Bureau, FirstCentral Credit Bureau) for comprehensive credit checks and reporting, enabling responsible lending practices.
   • Other third-party services like accounting software, CRM systems, and data analytics platforms to create a holistic financial ecosystem.
4. Cybersecurity Threats Are More Sophisticated
   • CBS must include advanced security measures to protect against evolving cyber threats.
   • Biometric authentication (compulsory under CBN’s 2024 guidelines for certain transaction types) for enhanced user verification.
   • DDoS protection (targeted attacks rose 200% in 2025, aiming to disrupt services and extort fintechs).
   • End-to-end encryption for all data in transit and at rest, regular security audits, and compliance with international security standards like ISO 27001.
5. CBN’s Regulatory Sandbox is Expanding
   • New 2026 proposals may require CBS to support:
   • Open banking APIs for secure and controlled data sharing with third-party providers, fostering innovation and competition.
   • Automated stress-testing for liquidity reporting and capital adequacy, ensuring financial stability and compliance with prudential regulations.
   • Integration with emerging technologies like blockchain for specific use cases, such as cross-border payments or digital asset management.

3. Understanding Core Banking Software: A Nigerian Fintech’s Perspective

What is Core Banking Software?

CBS is the engine powering all financial operations. For Nigerian fintechs, it must be a comprehensive platform that handles customer accounts, transactions, loans, deposits, and regulatory reporting. It’s the central nervous system that ensures all financial activities are recorded, processed, and managed accurately and securely. A robust CBS is not just about functionality; it’s about reliability, speed, and compliance.

Off-the-Shelf vs. Custom-Built CBS

The decision between an off-the-shelf solution and a custom-built one is critical and depends heavily on a fintech’s specific needs, budget, and long-term strategy.

• Off-the-Shelf (e.g., Temenos, Mambu, Oracle Flexcube):
  • Pros: Faster deployment (~6 months), proven track record, extensive features, regular updates, and often a larger support ecosystem. They come with pre-built modules for common banking functions.
  • Cons: May lack flexibility for highly localized products like ajo (collective savings schemes) or specific agency banking models prevalent in Nigeria. Customization can be expensive and time-consuming, potentially negating the initial speed advantage. Licensing fees can be substantial.
  • Best For: Fintechs that need a robust, internationally recognized solution with strong compliance features and are willing to adapt their processes to the software’s capabilities.
• Custom-Built (e.g., Appzone, or in-house development):
  • Pros: Tailored precisely to Nigeria’s unique market demands, allowing for deep integration with local payment systems, cultural nuances, and specific product offerings. Offers maximum flexibility and control over the technology stack.
  • Cons: Costs 3–5x more (₦500M–₦2B upfront) and takes significantly longer to develop (18–36 months). Requires a large, skilled in-house development team and carries higher risks related to bugs, maintenance, and future scalability.
  • Best For: Large, established fintechs with substantial capital, unique business models that off-the-shelf solutions cannot support, and a long-term vision for proprietary technology.

4. Key Evaluation Criteria for Core Banking Software in Nigeria (2026)

Choosing the right CBS is a complex decision that requires a thorough evaluation across multiple dimensions. For Nigerian fintechs, certain criteria hold more weight due to the unique market conditions and regulatory environment.

6. Red Flags: What to Watch Out For

When evaluating core banking software, it’s crucial to identify potential pitfalls that could lead to significant financial losses, operational headaches, or regulatory non-compliance. These red flags often indicate a mismatch between the vendor’s offering and your fintech’s needs, or a lack of transparency that could prove costly in the long run.

1. Hidden Costs
   • Vendors charging extra for services that should be standard or included in the base package. Always scrutinize contracts for line items that could escalate costs unexpectedly.
   • Examples:
   • API calls (e.g., ₦10 per BVN verification, ₦5 per NIP transaction beyond a certain threshold). These can quickly accumulate for high-volume fintechs.
   • Regulatory updates (e.g., ₦50M for implementing changes to CBN guidelines or new reporting formats). These should ideally be part of the annual maintenance fee.
   • Additional fees for specific modules (e.g., fraud detection, CRM, analytics) that were not clearly itemized during initial discussions.
   • High costs for data migration from your existing systems.
2. Lack of Local Data Centers or Data Residency Compliance
   • The CBN’s 2025 data residency rules are becoming increasingly stringent, requiring financial institutions to store critical customer data within Nigeria or in CBN-approved jurisdictions.
   • Fintechs using CBS providers that host data exclusively on foreign servers (e.g., AWS Frankfurt, Azure Ireland) may face penalties, compliance issues, or even license revocation. Always verify the vendor’s data hosting strategy and its alignment with Nigerian regulations.
3. Vague Service Level Agreements (SLAs)
   • A robust SLA is essential for ensuring operational continuity and accountability. Avoid contracts that don’t clearly define performance metrics, uptime guarantees, and compensation for outages.
   • Look for guaranteed 99.9% uptime (or higher for critical systems), clear response and resolution times for different severity levels of issues, and financial penalties or service credits for non-compliance.
   • Vague language around “best effort” or “reasonable endeavors” should be a major concern.
4. Poor Integration Capabilities
   • If the CBS lacks well-documented, modern APIs or struggles to integrate with essential Nigerian financial infrastructure (NIBSS, BVN, local payment gateways), it will severely limit your fintech’s operational efficiency and product development.
   • A CBS that requires extensive custom coding for every integration is a sign of an outdated or inflexible architecture.
5. Vendor Lock-in & Exit Strategy
   • Be wary of vendors that make it difficult or expensive to migrate your data out of their system if you decide to switch providers.
   • Ensure your contract includes clear terms for data export, ownership, and transition support.
6. Lack of Industry-Specific Expertise
   • If the vendor’s sales and support teams demonstrate a poor understanding of Nigeria’s unique regulatory environment, payment landscape, or cultural nuances, it’s a significant red flag.
   • They may struggle to provide relevant solutions or support when issues arise.
