E-invoicing raises new risks for manufacturers and banks

As the Nigeria Revenue Service (NRS) rolls out real-time invoice validation, companies are discovering that their exposure depends not only on their own systems, but on how prepared their distributors, retailers and partners are.

For manufacturers and banks alike, the risk shows up where money is supposed to move smoothly.

Manufacturers depend on distributors issuing validated invoices before payments can clear, while banks sit in the middle of those flows, processing settlements, merchant payments and reconciliations that now rely on real-time invoice validation.

Where those links fail, payments can stall, invoices can be rejected, and operations can slow, regardless of whether goods have already moved. A company can be fully compliant internally and still face disruption if even a small part of its distribution network is not.

“Large manufacturers rely heavily on extensive distributor networks, and ensuring that those distributors are compliant is critical to maintaining uninterrupted operations,” said Farida Kabir, tax technology lead at PwC Nigeria, speaking at a recent tax technology webinar.

According to Kabir, invoicing no longer happens quietly; it happens in real time. If a distributor cannot issue a validated invoice, the transaction may exist physically but not digitally, and that breaks the chain for payments, VAT reporting and reconciliation.

This is the practical effect of FIRS’ e-invoicing framework. VAT-registered businesses are now required to generate, validate and transmit invoices through approved digital platforms, with each invoice carrying a unique verification code and timestamp.

The aim is to close VAT leakages and give tax authorities near-real-time visibility into transactions. For businesses, it means invoicing systems must work live, at scale, and without room for error.

The rollout has been phased. A pilot started in November 2024. From August 2025, companies with an annual turnover of N5 billion or more were required to begin onboarding, with enforcement running into November. Small and medium-sized enterprises are expected to follow from January 2026.

Large taxpayers were targeted first because of the large share they contribute to VAT revenue. Manufacturing alone accounted for over 22 percent of total VAT collections in the fourth quarter of 2024, with VAT contributions surging to about N6.72 trillion for the full year. Any improvement or disruption at that level has system-wide consequences.

For manufacturers, a non-compliant distributor can delay invoicing and payments throughout an entire supply chain. For large retailers, thousands of daily transactions across multiple tills mean that even small system failures can quickly translate into large penalty exposure.

Financial services firms, though not traditional sellers of goods, are exposed through merchant clients, payment rails and reconciliation systems that now depend on validated invoices to clear and settle transactions.

“Financial services companies carry enormous transaction volumes,” said Tim Siloma, Partner, tax and technology at PwC. “Any mis-implementation at that scale significantly increases compliance and operational risk.”

As companies scramble to adapt, a new compliance market is quietly taking shape. At least 16 National Information Technology Development Agency (NITDA) certified service providers, including Interswitch, have been approved to support integration. They offer invoicing platforms, ERP extensions and API connections built to meet FIRS’ technical requirements, including a 55-field data standard and a PEPPOL-based architecture.

Yet uptake has been slower than policymakers might have hoped. Of more than 5,000 eligible large taxpayers nationwide, only about 1,000, roughly 20 percent, had commenced integration by August 2025. Early adopters include MTN Nigeria, IHS and Huawei Nigeria, while many others have requested extensions.

“Most companies are still in the process of implementation,” said Ayodapo Bamidele, a tax-technology expert. “Integration is not trivial, especially for firms with legacy systems.”

For many mid-sized firms, building and maintaining these systems internally is proving too expensive or too complex. Outsourcing compliance has become the practical choice, even though it introduces new recurring costs through subscriptions or per-invoice fees. The trade-off is simple: pay for compliance, or risk operational disruption.

Beyond operations, the biggest long-term shift may be in data. Every validated invoice now feeds structured, machine-readable information to tax authorities in near real time.

“By ensuring that data is structured, tax authorities can apply analytics and machine learning to identify under-reporting and potential tax evasion,” Siloma said.

For FIRS, this enables risk-based audits and targeted enforcement. Countries such as Mexico, Uruguay and Italy already operate similar systems, with documented improvements in VAT visibility and compliance.

The same data that powers e-invoicing for tax compliance can also reshape how businesses understand their own operations. By capturing transaction details in real time, e-invoicing gives firms immediate insight into sales cycles, customer behaviour and changing demand patterns.

“E-invoicing data allows businesses to understand peak sales periods, consumer behaviour and strategic shifts in real time,” said Kenneth Erikume. “It turns invoicing from a compliance exercise into a management and planning tool.”

The unresolved issue is trust. Nigeria’s Data Protection Act 2023 offers broad safeguards, but remains vague on how long tax data can be retained, who can access it, and how it may be shared across agencies. As real-time monitoring expands, those questions are becoming harder to ignore.

As enforcement tightens and smaller businesses prepare for future phases, the winners are likely to be service providers and large firms that move early and turn compliance data into insight. The losers may be under-capitalised distributors and retailers that cannot keep up, and potentially small businesses and citizens if compliance costs and data risks are pushed down the chain.

The real question is whether e-invoicing will just make taxes easier and businesses smarter, or if it will create new problems around who controls data and who benefits in Nigeria’s economy.
