In our experience across operational mandates, the typical PME or mid-market company carries 2030% in structural cost overruns that are invisible to standard P&L analysis. They accumulate not through bad decisions but through good decisions made in different contexts, never revisited.
The Accumulation Problem
Cost overruns in PME and mid-market companies rarely result from a single bad decision. They result from an accumulation of individually rational decisions made under different assumptions about growth, headcount, supplier relationships, real estate, IT infrastructure that were never collectively revisited as conditions changed.
The result is a cost architecture that reflects the company's past rather than its present. Contracts signed in a growth phase, maintained in a contraction. Supplier relationships that were competitive in 2019, no longer challenged in 2024. Headcount structures that map to a previous organizational design. Technology subscriptions bought for capabilities never fully deployed.
The Four Hidden Cost Categories
In our operational diagnostic work, four categories consistently account for the majority of recoverable cost:
1. Supplier contract drift (typically 812% of procurement spend)
Contracts signed at market rates 35 years ago, never renegotiated. Markets move; contracts don't unless someone makes them. In categories with significant commodity exposure energy, logistics, raw materials this gap compounds annually. The fix is systematic: a structured renegotiation programme with clear market benchmarks and explicit walk-away positions.
2. Organizational layer accumulation (510% of personnel cost)
As organizations grow, management layers accumulate. As they stabilize or contract, layers rarely reduce symmetrically. The result is supervision ratios that no longer match operational requirements cost that adds coordination burden without adding output. Restructuring these layers requires political will but rarely significant disruption if done with precision.
3. IT and software cost sprawl (36% of G&A)
SaaS proliferation has made this category increasingly significant. Subscriptions bought for specific projects, maintained indefinitely. Duplicate tools serving similar functions in different departments. Enterprise licenses for software used by 20% of the intended user base. A systematic audit of software spend against actual utilisation typically recovers 3040% of category cost.
4. Real estate and facility underutilisation (variable, often 1525% of facility cost)
Post-2020 working patterns have left most organisations with more physical space than they need. The reluctance to right-size driven by assumptions about future growth or organisational identity is often the single largest recoverable cost item. The recovery requires accurate space utilisation data and a decision framework that separates operational needs from historical habits.
The Diagnostic Method
Identifying hidden cost requires a different analytical approach from standard P&L review. Standard P&L analysis measures cost in aggregate categories. Hidden cost analysis requires mapping cost to activity understanding what each cost element is producing, for whom, and whether that production justifies its expense at current rates.
This is an operational intelligence exercise before it is a financial one. It requires access to operational data, supplier contract terms, utilisation metrics, and organisational mapping that finance teams rarely hold in one place.
The diagnostic typically takes 46 weeks for a company in the €20200M revenue range. The findings rarely surprise operational managers, who know where waste accumulates. They consistently surprise ownership and financial leadership, who see the P&L but not the architecture beneath it.
