The 5 biggest mistakes in purchasing
This blog post examines five common misconceptions about procurement that lead to the function being underestimated and viewed too narrowly in many organisations. It focuses on why modern procurement is about much more than simply cutting costs and processing orders: it acts as a strategic lever for supply capability, risk management and better decision-making through market transparency and robust supplier relationships.
Procurement is still underestimated in many organisations. All too often, it is reduced to two tasks: driving down prices and processing orders. This is understandable – cost savings are visible, easy to measure and quick to communicate. But this is only part of the picture.
Modern procurement is a strategic lever. It secures supply chains, manages risks, strengthens competitiveness and ensures that what has been decided and negotiated is actually implemented in day-to-day operations. In practice, we repeatedly encounter the same errors in thinking – and they prevent procurement from realising its full potential.
Mistake 1: The main purpose of procurement is to reduce costs.
This phrase is so widespread that it almost seems like a law of nature. Yes: cost management is very important. But when procurement is reduced to mere ‘savings’, two things happen: firstly, the focus narrows to price rather than total value (Total Cost of Ownership, supply risks, quality, flexibility, capacity for innovation). Secondly, procurement becomes reactive: it only comes into play when it comes to approvals or discounts – not when the actual course is being set.
Cost savings are evident, but they are only part of the story. The real challenge also lies in risk management, supply continuity and robust supplier relationships.
What matters instead is: ensuring supply reliability (particularly for critical product groups, single-source suppliers and volatile markets), identifying risks at an early stage (supplier creditworthiness, capacity, geopolitical dependencies, contractual risks) and demonstrating the value added – not just ‘€ saved’, but also ‘shortage prevented’, ‘time-to-market accelerated’ or ‘quality stabilised’.
Mistake 2: The best negotiators are the loudest ones in the room.
We’re all familiar with the picture: tough talk, dominance, maximum pressure. In reality, ‘loud’ rarely leads to ‘good’ – and almost never to lasting success. Preparation beats volume. Those who can remain calm and are well prepared achieve the better results.
Good negotiation is less about putting on a show and more about craftsmanship. Objectives, BATNA (Best Alternative to a Negotiated Agreement) and limits must be clear. Cost and value drivers should be understood, rather than simply demanding blanket percentage reductions; options need to be prepared (alternative suppliers, specification variants, batch sizes, contract terms, service levels). And crucially: stakeholder alignment ideally takes place before you even approach the supplier. Particularly in tight supply markets, it is not the loudest voice that wins, but the one who analyses the situation thoroughly and manages relationships professionally.
Mistake 3: The purchasing department makes the decision.
Formally, procurement is often part of the process: tendering, requesting quotations, awarding the contract. In reality, however, in many cases the supplier has already been chosen before procurement is even involved. At that point, the process shifts from selection to securing the contract.
This is risky: competition is simulated rather than harnessed, room for negotiation shrinks, dependencies are addressed too late, and procurement becomes a compliance checkpoint rather than a value driver. It is helpful to integrate procurement at an early stage into the process of clarifying requirements and defining specifications, and to structure governance in such a way that procurement does not simply sign off at the end, but is involved in shaping the process from the outset. Roles should be clearly defined: the line department defines the requirements; procurement designs the market approach, risk and contractual frameworks, and facilitates the decision-making process.
Mistake 4: Suppliers are the biggest challenge.
Of course, suppliers can be difficult. In many organisations, however, the greater friction lies within. Internal stakeholders often pose a greater challenge to procurement than external partners. Anyone who ignores this is fighting the wrong battle.
Typical internal hurdles include unrealistic timetables, a lack of specifications, pre-selected suppliers, inconsistent requirements (technology vs. quality vs. finance) or shadow procurement. Modern procurement is therefore also about interface and change management: managing expectations, creating transparency regarding costs and risks, designing processes to help rather than hinder, and getting stakeholders on board – without compromising procurement principles.
Mistake 5: Once the contract has been signed, the job is done.
Once the contract has been signed, the real work often only just begins. Value is created during implementation: service delivery, quality, delivery dates, escalations, renegotiations and performance tracking. What was negotiated and what is ultimately delivered are often two different things.
One under-utilised lever is consistent supplier and contract management: making KPIs and SLAs measurable (rather than simply leaving them on paper), establishing regular meetings and reviews (e.g. quarterly business reviews), identifying deviations at an early stage (delivery performance, quality, price or index clauses) and feeding lessons learnt back into the next procurement process. This is where procurement as a project differs from procurement as a system.
Conclusion
These five misconceptions share a common core: procurement is viewed as too late, too narrow or too operational. Positioning procurement as a strategic function provides leverage that goes far beyond cost savings: a more stable supply chain, lower risks, better decision-making through market transparency, stronger supplier relationships, and demonstrable compliance with contractual agreements.
