Nigeria is moving from paper and PDF invoices to a structured, government-validated invoicing system. The Merchant Buyer Solution (MBS), administered by the Nigeria Revenue Service (NRS), is being rolled out in phases, and the businesses now in scope are larger than a small handful of multinationals. This article explains what e-invoicing is, how it works, and what to do to prepare.
How it works
E-invoicing under the MBS is a pre-clearance model for business-to-business and business-to-government transactions, and a real-time reporting model for business-to-consumer transactions. In practice, this means:
- Invoices are generated in a structured format (JSON or XML, aligned with the Peppol BIS standard) rather than as a plain document.
- Invoices are transmitted through the NRS platform, either directly or via an accredited Access Point Provider (APP) or System Integrator (SI), for validation before or as the transaction is recorded.
- A valid e-invoice carries a cryptographic stamp identifier issued through the system.
- Records must be archived for a defined period; published guidance cites 6 years generally, with 7 years for e-invoices specifically retained upon request by the tax authority.
The phased rollout
Published timelines, cross-checked across multiple sources, describe the following bands. Businesses should confirm the current position directly with the NRS, since notices have adjusted dates before:
| Taxpayer category | Approximate turnover | Reported go-live |
|---|---|---|
| Large taxpayers | ₦5 billion and above | Live since late 2025 |
| Medium taxpayers | ₦1 billion to ₦5 billion | 1 July 2026, with enforcement from January 2027 |
| Emerging/small taxpayers | Below ₦1 billion | Reported for 2027, exact date to be confirmed |
Why this matters to taxpayers
E-invoicing changes how VAT compliance is evidenced. Where invoices are validated in real time by the tax authority, the historical practice of reconciling VAT returns against internally kept invoices at year-end is being replaced by a system where the tax authority has visibility into transactions as they happen. Businesses that have not reviewed their invoicing systems and data quality may find themselves unable to issue compliant invoices once their band becomes mandatory.
Tax implications
- VAT accuracy becomes more visible. Since invoices are validated by the NRS platform, discrepancies between invoiced VAT and remitted VAT are more readily identifiable.
- Non-compliance carries penalties. Published guidance notes that penalties apply for failure to comply once a business's band is mandatory.
- Data quality matters. Customer and product data feeding into invoices needs to be structured and accurate, not just human-readable.
- Businesses below the current threshold should still plan ahead, since the rollout is progressive and earlier bands have already reached their compliance dates.
Step by step: how to prepare
- Confirm your taxpayer band based on annual turnover, and check the current mandatory date for that band on the NRS website.
- Review your invoicing system. Determine whether your current software can generate structured (JSON/XML) invoices or needs an add-on.
- Choose an integration route. Decide whether to integrate directly with the NRS MBS or work through an accredited Access Point Provider or System Integrator.
- Clean your data. Ensure customer details, product/service descriptions and tax codes are accurate and complete.
- Test the process. Where the NRS provides a testing or sandbox environment, use it before your mandatory date.
- Train staff involved in invoicing, sales and finance on the new process.
- Set up archiving that meets the retention periods required for invoice records.
- Monitor NRS notices for any change to your band's timeline.
Why engage a professional consulting firm
- Band confirmation. A professional can confirm which category your business falls into and the applicable compliance date.
- System assessment. An accountant can review whether your accounting or ERP system needs adjustment or a new integration.
- VAT reconciliation. A firm can help ensure your VAT filings match what is being reported through the e-invoicing platform.
- Transition planning. Moving from manual or semi-manual invoicing to a validated digital process benefits from a planned timeline rather than a rushed one.
Why every business should comply
E-invoicing compliance is not optional once a business's band becomes mandatory. Non-compliance can result in penalties and can also affect a business's ability to have its invoices accepted by customers who are themselves required to transact only through the validated system. Early preparation reduces the risk of disruption to invoicing and cash collection.
Tips and points to watch
- Do not wait for enforcement. Published guidance distinguishes between a "go-live" date and an "enforcement" date; using the gap to test and adjust is preferable to waiting until penalties apply.
- Review your customer base. If key customers are large taxpayers already required to use e-invoicing, your invoices to them may need to meet the standard sooner than your own mandatory date.
- Keep both digital and readable formats, since a visual representation of the validated invoice may still be needed for customers.
- Track APP and SI accreditation lists published by the NRS or NITDA when selecting a service provider.
