E-invoicing forces Nigerian firms into real-time transparency

Nigeria’s push to implement electronic invoicing is forcing businesses to rethink not just how they file taxes but also how they record revenue, manage suppliers, and structure their internal operations. “It is meant to address a high rate of tax evasion; moving the Nigerian tax system from just a trust-based reporting to a data-verified reporting,” said Eben Joels, managing director at Stransact, during a recent Stransact webinar on the Nigeria Revenue Service’s (NRS) e-invoicing system.

The new framework requires businesses to generate invoices electronically and transmit them via accredited platforms to the tax authority for validation before issuing them to customers. Once cleared, each invoice carries a digital stamp, effectively determining its legitimacy for tax purposes. “Any invoice that is not authenticated by the NRS is illegal. When it goes through the system, it gets a digital stamp, which authenticates it,” Eben explained.

The shift marks a departure from post-transaction reporting to continuous, real-time monitoring, giving authorities direct visibility into commercial activity.

Beyond systems and infrastructure, the reform is also exposing deeper cultural resistance to transparency among business owners. “We have clients that we struggle to teach the principles of transparency of their revenue to their own staff,” said Tunde Awopegba, CTO Doftwerks. “You can imagine a business owner who is not even willing to let their staff have a view, except maybe one or two people in finance, of how much they are making.”

The requirement to transmit transaction data in real time to tax authorities is therefore expected to challenge long-standing practices where revenue figures are tightly controlled or selectively disclosed. Analysts say this could significantly reduce underreporting and the use of backdated or fictitious invoices, practices that have historically weakened tax collection.

For many firms, particularly those reliant on manual processes or fragmented accounting systems, the change is forcing a costly and complex transition. Businesses are now required to integrate their accounting systems with the invoicing platform, often through third-party service providers, while ensuring that their internal processes align with the new requirements. For small and medium-sized enterprises (SMEs), many of which still rely on spreadsheets or informal record-keeping, the adjustment could prove especially difficult.

However, one of the most immediate and less obvious impacts is being felt across supply chains. “We discovered some of their suppliers are not even registered with the NRS, and they have been doing business with them,” said Muhammed Bawa, head of project management, NRS E-invoicing solution.

The implication is that compliance is no longer limited to individual firms but extends to their entire network of vendors and partners. Businesses may be forced to reconsider relationships with non-compliant suppliers, as invoices issued outside the system risk being rejected for tax purposes.

The cascading effect could accelerate the formalisation of Nigeria’s largely informal economy, where many transactions remain undocumented. By embedding validation at the point of transaction, the system narrows opportunities for tax evasion while creating a more traceable commercial environment.

Still, concerns remain around the cost of implementation and the broader implications of increased transparency. Integration expenses, service provider fees, and operational adjustments could place additional strain on businesses already navigating a challenging economic climate.

There are also fears that greater visibility could expose companies to excessive scrutiny or misuse of sensitive financial data, a concern often described by stakeholders as the ‘Nigerian factor.’ Responding to these concerns, Bawa noted that the system is designed to improve transparency on both sides and reduce arbitrary enforcement.

While authorities maintain that the system will ultimately reduce disputes and improve efficiency in tax administration, businesses face a steep learning curve as they adapt to a new regime where transactions are monitored in real time.

For many, the transition represents more than a compliance exercise. It signals a structural shift in how business is conducted, where informal practices give way to digitised, traceable processes, and where visibility, rather than discretion, becomes the foundation of tax reporting.
