Operational Due Diligence: Analyzing & Optimizing Supplier Costs

Operational Due Diligence: How Reliable Are Your Supplier Costs, Really?

Operational due diligence, just like Venture Due Diligence, is considered a central component of any corporate audit. The focus is on processes, structures, and operational performance. However, one crucial factor is often overlooked: the actual reliability of supplier costs.

For purchasing departments, cost engineers, and sales managers in particular, the quality of this data determines whether assumptions are sound or whether corrections will be necessary later on.

Why Supplier Costs Are Critical in Operational Due Diligence

In many due diligence processes, the assessment of operating costs is based on historical purchasing data, existing contracts, and simplified benchmarks. This approach falls short.

Supplier prices rarely reflect the actual cost structure. They are the result of negotiations, market dynamics, and individual margin strategies. A thorough operational due diligence must therefore go deeper and analyze the underlying cost drivers.

Especially in volatile markets, such as those for commodities or energy, significant discrepancies arise between current prices and realistic costs.

Cost Breakdown as the Basis for Informed Analysis

A reliable assessment of supplier costs starts with transparency. Cost breakdown modelsmake it possible to systematically break down prices into their component parts.

Typical ingredients include:

- Material costs
- Manufacturing costs
- Labor costs
- Overhead costs
- Logistics and energy costs

The added value comes from quantifying these elements. This enables procurement organizations to identify which factors drive pricing and where potential risks lie.

A real-world example: When oil prices rise, this affects not only material costs but also transportation and energy costs. Without a structured analysis, these effects often go unnoticed.

Should Costing as a Key to Valuation

Should-costing adds a crucial perspective to the cost breakdown. Instead of actual data, a target cost model is developed based on realistic market and production assumptions.

This method answers a key question:
What price would be justified under efficient conditions?

Using this approach as part of operational due diligence offers several advantages.
Unrealistic price levels become apparent. Negotiation potential can be quantified. Dependencies on individual suppliers become clearer.

At the same time, this provides a solid foundation for strategic decisions in procurement and sales.

Common weaknesses in the analysis of supplier costs

Many companies underestimate the complexity of global supply chains. Costs are often viewed in isolation, without taking into account their interdependencies.

Another common mistake is the linear adjustment of prices. Rising raw material costs are passed directly on to end products without examining the actual cost structure. This oversimplification leads to distorted results.

Existing supply contracts can also distort the picture. Price-fixing and delayed adjustments mean that changes in the market only become apparent later on.

Another critical issue is the lack of differentiation between different suppliers. Different production sites, technologies, and economies of scale result in significant cost differences.

Relevance for Purchasing and Sales

For procurement, thorough operational due diligence means one thing above all else: a better basis for decision-making. Price negotiations can be conducted on a fact-based foundation. Risks in the supply chain are identified early on.

There is also clear added value in sales. A realistic assessment of the cost structure enables more accurate calculations and more stable margins.

The integration of procurement, cost engineering, and sales thus becomes a key strategic factor for success.

Conclusion: Transparency is key to the quality of due diligence

The quality of an operational due diligence stands or falls on the depth of the cost analysis. Supplier prices alone do not provide a reliable picture. Only by combining cost breakdown and should costing can a realistic assessment be made.

Companies that adopt this approach reduce uncertainty and establish a solid foundation for informed decision-making. In an increasingly volatile market environment, this capability becomes a decisive competitive advantage.
