Compliance Guide: How Businesses Can Integrate Nigeria’s E-Invoicing System

Step 1: Understand the Requirements

• All businesses registered with FIRS are required to issue invoices digitally via the National E-Invoicing platform.

• Traditional paper invoices, Excel-generated receipts, or manually issued PDFs will no longer be valid for tax reporting.

• Each transaction must pass through the e-invoicing system to be recognized by FIRS.

Step 2: Register with FIRS and Approved Service Providers

• Confirm your business is registered with FIRS and has a Tax Identification Number (TIN).

• Select one of the 16 approved service providers (e.g., Interswitch, Remita, Courteville, Etranzact) to integrate your invoicing system with the FIRS platform.

• Service providers will help configure your accounting or ERP software to automatically generate e-invoices in the required format.

Step 3: Integrate and Test Systems

• Work with your service provider or IT team to:

  • Connect your point of sale (POS), ERP, or accounting system to the FIRS e-invoicing platform.

  • Ensure each invoice includes mandatory fields (supplier, buyer, description, quantity, unit price, tax, total).

  • Validate test invoices to ensure they generate a unique FIRS reference number.

• Use the onboarding window (until November 1, 2025) to test and fix issues.

Step 4: Train Staff

• Train finance, sales, and IT staff on:

  • How to issue invoices through the platform.

  • How to confirm each invoice has a unique reference number.

  • What to do if invoices are rejected by the system.

Step 5: Issue Only E-Invoices Going Forward

• From the enforcement date (November 1, 2025), all invoices must be issued through the e-invoicing system.

• Customers and suppliers should be informed that only FIRS-compliant e-invoices will be valid for tax purposes.

Step 6: Monitor and Report Transactions

• FIRS has mandated that all payment gateways report transactions directly.

• Ensure that all invoices raised in your system are declared, as hidden invoices can still be traced through payment records.

Step 7: Maintain Compliance and Support

• Use FIRS’ decentralized support centers and service provider helpdesks for issues.

• Stay updated on policy changes and compliance reminders from FIRS.

• Keep proper digital archives of all e-invoices for audits.

Deadline Reminder: Businesses must fully transition by November 1, 2025. Non-compliance could trigger penalties, audits, and loss of tax credits.
