The hidden costs of unstructured procurement

Consider a scenario that ELVI Partners encounters regularly in Belgium: a company with around €40 million in annual purchases, a finance team focused on margins, and a procurement function that technically exists. In the space of twelve months, the material amount of cost quietly disappeared from the P&L, without a single redundancy, without a failed acquisition, and without anyone noticing until a structured procurement assessment surfaced the issue. This is an illustrative example of a dynamic that ELVI Partners encounters regularly. The details vary from one organisation to the next. The underlying pattern does not.

The culprit is not mismanagement. It is the absence of structure.

Unstructured procurement is one of the most consistent and underestimated profit leaks in companies of all sizes. Unlike most cost drivers, it compounds silently, year after year, invisible to the standard management dashboard. The team at ELVI Partners has observed this pattern across a significant number of procurement engagements in Belgium. The same mechanisms surface repeatedly. The same costs accumulate. And in most cases, they are significantly recoverable.

This article breaks down the four main hidden cost drivers of unstructured procurement, provides an indicative view of their financial impact, and explains why investing in structured procurement leadership is one of the most effective decisions a CFO or CEO can make.

What is unstructured procurement and why does it persist?

Unstructured procurement does not mean procurement is absent. In most affected organisations, someone is placing orders, approving suppliers and signing contracts. What is missing is the architecture: the governance frameworks, the sourcing strategies, the performance measurement systems and, critically, the senior expertise required to drive consistent improvement.

In many organisations, procurement is still perceived as an administrative function rather than a strategic one. It receives limited investment in talent, rarely holds a seat at the table where financial strategy is discussed, and is measured, if at all, on speed of delivery rather than value created. KPMG and T The Chartered Institute of Procurement and Supply (CIPS) has documented this gap between the strategic potential of procurement and the reality of how it is typically resourced and positioned. This perception gap is precisely where hidden costs accumulate.

The financial arithmetic behind this matters. For a company where purchases represent a significant share of revenue, a one percent reduction in purchasing costs can deliver a materially higher bottom-line impact than a one percent increase in sales, because procurement savings flow directly to operating profit without the associated cost of generating additional revenue. The precise multiplier depends on the company's cost structure and margin profile, but procurement research consistently points to this asymmetric leverage effect. When ELVI Partners presents this logic to a CFO, it reframes procurement from a back-office function into a financial lever.

The four hidden cost drivers

Hidden procurement costs do not appear randomly. Based on the experience of ELVI Partners across procurement engagements, they tend to cluster around four core mechanisms. This is a practical framework, not an exhaustive academic taxonomy. Each mechanism is addressable, but only once it has been identified and measured.

1. Maverick spend

Maverick spend refers to purchases made outside approved contracts and supplier lists. CIPS defines it clearly as expenditure that bypasses the organisation's procurement processes and approved supplier base. The proportion of spend that falls into this category varies considerably by sector and maturity level, but industry benchmarks consistently indicate it can represent a material share of total addressable spend in organisations without enforced governance, with figures cited in procurement literature typically ranging from 10 to 30 percent depending on the category and control environment.

Each rogue purchase represents a missed negotiation, a lost volume discount, and a compliance exposure. The cost premium on maverick purchases tends to be meaningful: procurement practitioners and advisory firms generally estimate it at several percentage points above contracted rates, though the exact figure depends heavily on the category, the supplier and the degree of market competition. Even a conservative estimate translates into a significant recoverable overspend for any company operating at scale.

2. Supplier dependency and concentration

When a disproportionate share of category spend flows to a single supplier, negotiating leverage diminishes and supply risk increases. Supplier concentration rarely appears overnight. It builds quietly over years, never flagged because no one is tracking it. Price increases go unchallenged. Alternative sources are never developed.

The financial consequences of concentrated supplier relationships compound over time. Without periodic market benchmarking and competitive tension in the supply base, price drift becomes the norm. The disruptions that affected European supply chains between 2020 and 2023 made the operational dimension of single-source dependency starkly visible. At ELVI Partners, supplier concentration analysis is a standard component of every procurement maturity assessment we conduct.

3. Reactive purchasing and process friction

Without streamlined sourcing workflows, the time from need identification to delivery extends significantly. This leads to emergency purchasing, which consistently carries a price premium above planned purchase rates. Procurement practitioners and advisory firms have consistently documented this premium, with estimates typically ranging from 15 to 25 percent above contracted rates, depending on category urgency and supplier leverage at the time of the emergency buy.

The direct cost of emergency buys is compounded by the indirect cost of management attention diverted to firefighting. In the procurement environments that ELVI Partners has assessed, reactive purchasing often accounts for a double-digit share of total purchase volume, a proportion that drops significantly once basic governance and forward planning are in place.

4. Total cost of ownership blindness

The most insidious driver is the habit of selecting suppliers based on quoted purchase price alone, while ignoring maintenance costs, quality failure rates, switching costs and full lifecycle performance. This is known as total cost of ownership (TCO) blindness.

For capital equipment and technical services in particular, the total cost of ownership over a product's lifecycle can substantially exceed the original purchase price once maintenance, downtime, energy consumption and end-of-life costs are factored in. The degree of this gap depends on the asset type and operating context, but in categories such as industrial machinery, facilities services or IT infrastructure, it is common for lifecycle costs to far outweigh the initial procurement price. Choosing the cheapest option without TCO analysis frequently produces the most expensive outcome. At ELVI Partners, TCO assessment is one of the first tools we apply in any procurement transformation engagement.

An indicative view of the financial impact

To give this a sense of scale, consider a company with €40 million in annual purchases operating without procurement governance. The following estimates are illustrative rather than precise and are based on conservative assumptions aligned with ranges cited in procurement literature. All figures are expressed on an annual basis.

1. Maverick spend (estimated at 15% of purchases, with a conservative 8% price premium above contracted rates): approximately €480,000 in recoverable annual overspend.
2. Supplier concentration (estimated annual price drift of 3 to 5% above market rates across concentrated categories, representing 25% of total spend): approximately €300,000 to €500,000 per year in uncaptured savings from unchallenged pricing.
3. Reactive purchasing (estimated at 10% of volume with a 15 to 20% emergency premium): approximately €600,000 to €800,000 per year in avoidable cost premium.
4. TCO misalignment (estimated annual cost of suboptimal supplier selection on capital and service contracts, assuming 10% of spend in affected categories with a 20% lifecycle cost gap): approximately €800,000 per year in preventable excess cost.

Combined illustrative annual impact: between €2 million and €2.5 million per year for a company with €40 million in purchases, using conservative assumptions, in a typical mid-size organisation with limited procurement maturity. Using more moderate assumptions aligned with the broader range cited in procurement improvement literature, the total recoverable opportunity could extend to €4 to €5 million annually. These figures represent an indicative potential of 5 to 12 percent of total purchasing spend, consistent with improvement ranges documented in procurement research by McKinsey and CIPS, though actual results depend on the organisation's starting maturity level, spend categories and implementation quality.

Structured procurement leadership: the ROI case

The financial case for structured procurement is compelling. But process redesign alone is not enough. It requires deploying the right talent at the right seniority level, with the authority and the tools to drive sustainable change. This is the core of what ELVI Partners does.

The distinction that matters is between a transactional procurement function and a strategic procurement capability. The former manages orders. The latter manages value: supplier relationships, total cost of ownership, supply chain resilience, and the alignment of sourcing strategy with corporate financial objectives.

Whether ELVI Partners is engaged to place a permanent head of procurement, deploy an interim CPO, or provide advisory and staff augmentation support, the approach is built around four consistent steps.

• Procurement maturity assessment. ELVI Partners has developed its own Maturity Assessment methodology, which maps current-state processes, quantifies cost leakage across all four drivers, and identifies the highest-value improvement opportunities. This diagnostic step is non-negotiable. Without it, improvement efforts are guesswork. 
• Senior talent deployment. The impact of an experienced, strategically minded procurement leader can begin to be visible within weeks. ELVI Partners places medior to senior procurement and supply chain profiles with the right combination of technical depth and business credibility to drive change at board level.
• Category management and supplier strategy. Structure spends by category, develop market intelligence per category, and define a differentiated strategy for critical versus commodity supply. Category management consistently ranks among the highest-impact procurement levers, with savings potential varying by category maturity, market competitiveness and the quality of the sourcing strategy applied.
• KPI framework and board reporting. Establish the measurement layer: savings validation, supplier performance scorecards, maverick spend tracking and CFO-level procurement reporting. What is not measured does not improve. ELVI Partners helps build reporting frameworks that make procurement performance visible at the highest level of the organisation.

Organisations that invest in structured procurement governance can achieve significant savings on their addressable spend, with improvement potential typically cited between 5 and 15 percent in procurement research from CIPS and McKinsey, depending on the organisation's starting maturity level, the categories in scope and the rigour of implementation. For a company spending €40 million annually on purchases, even the lower end of this range represents a meaningful bottom-line contribution, generally realised progressively over a period of 12 to 24 months.

Conclusion: the invisible becomes visible

Unstructured procurement does not announce itself. It does not appear as a line item in management accounts. It surfaces instead as margin compression that cannot be explained, as supplier conflicts that recur without resolution, as delivery crises that always seem to catch the organisation off guard.

The good news is that a significant part of these costs can be recovered. They represent an untapped savings opportunity that structured procurement leadership can convert into measurable EBITDA improvement, stronger supplier relationships and a more resilient supply chain.

ELVI Partners works with Belgian companies to close the gap between what their procurement function currently costs them and what it could deliver. If you are a CFO, CEO or operations director who suspects procurement is underperforming, the right starting point is a maturity assessment. The numbers that surface are rarely comfortable. They are almost always actionable.

Key takeaways

• ELVI Partners uses a practical framework of four main hidden cost drivers of unstructured procurement: maverick spend, supplier concentration, reactive purchasing and total cost of ownership blindness. Each is measurable and, to a significant degree, recoverable.
• For a company with €40 million in annual purchases, the combined annual impact of these four drivers can conservatively range from €2 to €5 million, representing 5 to 12 percent of total purchasing spend, based on illustrative assumptions aligned with procurement literature.
• Procurement savings have a disproportionate impact on operating profit compared to equivalent revenue growth, because they flow directly to the bottom line. The size of this advantage depends on the company's cost and margin structure, but the asymmetry is well documented across procurement research.
• Structured procurement improvement programmes can deliver savings of 5 to 12 percent of addressable spend, according to benchmarks and experience, with results depending on starting maturity, categories in scope and implementation quality.

ELVI Partners specialises in deploying senior procurement and supply chain talent through executive search, interim management and advisory, to help organisations in Belgium turn their procurement function into a source of measurable competitive advantage.
