Understanding Nigeria's E-Invoicing Mandate: What Businesses Need to Know

Nigeria’s tax landscape is undergoing a significant digital transformation with the introduction of mandatory e-invoicing requirements. The Federal Inland Revenue Service (FIRS) has rolled out the Merchant Buyer Solution (MBS) e-invoicing platform as part of its digital tax transformation strategy, fundamentally changing how businesses handle invoicing and VAT compliance.

What is the E-Invoicing Mandate?

Starting in July 2025, FIRS began implementing a phased rollout of mandatory e-invoicing for Nigerian businesses. This initiative aims to:

  • Boost tax compliance and transparency across all business transactions
  • Reduce revenue leakage through real-time transaction monitoring
  • Streamline VAT collection and remittance processes
  • Digitize the entire invoicing lifecycle from creation to archival

Who is Affected?

The e-invoicing mandate follows a phased approach based on business size:

Phase 1: Large Taxpayers (July - December 2025)

Businesses with an annual turnover of ₦5 billion or more were required to register and begin using the FIRS e-invoicing platform. This includes:

  • Major corporations and multinationals
  • Large-scale manufacturers
  • Wholesale and retail chains
  • Financial institutions

Phase 2: Medium Taxpayers (2026)

Businesses with annual turnover between ₦1 billion and ₦5 billion will be brought into the system.

Phase 3: Small Businesses (2026-2027)

Eventually, all VAT-registered businesses will be required to comply, regardless of size.

Key Requirements

1. Registration with FIRS

All affected businesses must:

  • Obtain a Tax Identification Number (TIN) if they don’t already have one
  • Register on the FIRS MBS e-invoicing platform
  • Receive a unique Business ID from their Access Point Provider

2. Real-Time Invoice Reporting

Businesses must report invoices to FIRS within specific timeframes:

  • B2B transactions: Invoices must be validated through the platform before issuance
  • B2C transactions: Invoices can be issued directly but must be reported within 24 hours

3. Technical Integration

Companies need to either:

  • Integrate their existing accounting/ERP systems with the FIRS platform via API
  • Use FIRS-approved e-invoicing software solutions
  • Adopt a compliant third-party platform like CompliantInvoice

Compliance Challenges

Nigerian businesses face several hurdles in meeting these requirements:

Technical Complexity

Many small and medium enterprises lack the IT infrastructure to integrate directly with FIRS systems. The technical requirements include:

  • API integration capabilities
  • Real-time data transmission
  • Secure authentication protocols
  • Invoice format standardization (XML/JSON)

Resource Constraints

Smaller businesses often struggle with:

  • Limited IT budgets for system upgrades
  • Lack of in-house technical expertise
  • Training staff on new processes
  • Managing the transition from paper-based systems

Operational Disruption

The switch to e-invoicing can temporarily disrupt business operations:

  • Learning curve for new software
  • Potential delays in invoice processing
  • Reconciliation challenges during transition
  • Customer onboarding to new invoice formats
