Every few months, a headline appears in the African newspaper about a municipality or revenue authority that has failed to collect what it is owed. The narrative is usually familiar: weak administration, ageing systems, or entrenched non-payment culture. All of these are real as these compounding mix of structural, systemic, and operational vulnerabilities. But in my experience, these are symptoms, not the root causes.
Often, defining the overall turnaround strategy is the first step in addressing the problem statement, however, the root cause circles back to implementation. More emphatically, the root cause of Africa’s revenue collection gap is advisory failure.
This is not in the sense that advisors have done bad work, though sometimes they have, in diagnosing the correct problem. However, this is in the sense that the advisory model itself has been wrong: too short, too technical, too divorced from the institutional reality of the organisations being advised.
That is the problem I have spent my career trying to solve. And it is why Ntiyiso’s evolution as a firm, anchored in Brand 3.0, matters to me personally.
The Scale of the Problem
The IMF estimates that the overall revenue gap for sub-Saharan African countries stands at 3 to 5 percentage points of GDP on average, with non-tax revenues particularly underutilised, contributing only 1 to 2% of total revenue collection compared to 10% or more in Latin America.1
In South Africa alone, aggregate consumer debt owed to the country’s 257 municipalities stood at R467 billion by December 2025, with more than 87% of that debt outstanding for longer than 90 days. This is not a payments culture problem. It is an institutional capacity problem.2
This is not uniquely South African. Across sub-Saharan Africa, under-collection of own-source revenue is one of the most consequential and least-addressed governance failures on the continent. And it is a failure that advisory firms have too often enabled, by delivering technically correct but institutionally disconnected advice.
The Complexity That Revenue Advisors Must Navigate
Revenue management in African governments sits at the intersection of technology, law, politics, behavioural economics, and public administration. Getting it right requires understanding all of these dimensions simultaneously, and knowing which lever to pull in which context.
A municipality in the Northern Cape faces a fundamentally different revenue challenge than one in Nairobi or Lagos. The legal framework is different. The economic base is different. The historical relationship between citizens and the state is different. The political economy of debt recovery is different. Generic frameworks, the kind that global advisory firms apply uniformly across markets, miss these differences almost every time.
“Revenue transformation is not a system problem. It is a capability problem, a culture problem, and a trust problem – the complexity is that, it is all these challenges intertwined.”
Why Trusted Partners Outperform Transactional Consultants
I have seen what happens when revenue advisory is done transactionally. A firm comes in, analyses the billing data, produces a debt recovery strategy, trains a handful of staff, and leaves. Twelve months later, collection rates have barely moved because the people responsible for implementation never truly owned the strategy. The knowledge walked out the door with the consultants.
The alternative, and it is what Ntiyiso’s Revenue Consulting practice is built around, is genuine capability transfer. We sit inside the institution. We work alongside the revenue teams. We help them build not just the skills but the confidence and the internal political capital to pursue revenue that powerful interests would prefer to leave uncollected.
That takes time. It takes trust. And it requires advisors who understand that their job is not to be needed forever. It is to make themselves redundant by building real capability.
Digital Transformation in Revenue: Enormous Potential, Enormous Risk
The digital transformation of revenue management is one of the most significant opportunities available to African governments right now. Mobile payment infrastructure, real-time data analytics, AI-assisted billing verification, digital cadastral systems: these tools can genuinely close the collection gap.
But they can also become expensive failures if they are implemented without the institutional readiness to use them. The World Bank’s governance assessments consistently identify weak implementation capacity and limited institutional readiness as the primary barriers to translating reform investments into results, not a lack of technical tools.3
The advisory firms that will make a real difference in this space are those that can bridge the technical and institutional dimensions of digital transformation. Not just implement the system, but build the institution that can operate, sustain, and evolve it. That is Ntiyiso’s value proposition in the digital era – to be the implementation partner of choice.
Authentic Insight: Knowing What the Numbers Cannot Tell You
Data is essential in revenue advisory. But data alone cannot tell you why a major employer has not paid rates in three years, or what it will take, politically, legally, and relationally, to bring them to a payment arrangement. That knowledge requires African advisors who understand the informal rules of the game.
It requires advisors who can walk into a room with a resistant debtor and understand, from the first five minutes of conversation, what the real objection is. It requires understanding the difference between inability to pay and unwillingness to pay, knowing that the solution to each is completely different.
That is the insight that Ntiyiso’s Revenue Consulting practice brings. It is grounded in African realities. And it is the reason our results, in institution after institution, are different from what generic advisory produces.
Africa is not a continent that cannot pay its way. It is a continent that needs advisory partners capable of unlocking its fiscal potential in a way that is technically sound, institutionally embedded, and authentically grounded. Ntiyiso Brand 3.0 is our signal to the market: we are that partner. And we are just getting started.
