Procurement Controlling: KPIs That Steer Purchasing

How much did the team save last quarter? Where are costs running out of control? Which suppliers keep their promises? A head of purchasing who cannot answer these questions at quarter-end is flying blind. This is exactly where procurement controlling brings clarity. It translates day-to-day purchasing work into reliable figures and makes the function plannable, comparable and strong at the negotiating table. And the more supply chains fluctuate and material prices rise, the more this transparency turns into a genuine competitive advantage.

In brief: Procurement controlling is the systematic planning, steering and monitoring of all purchasing activities based on key performance indicators (KPIs). It splits into an operational part (day-to-day efficiency) and a strategic part (long-term value creation). What matters is not having as many metrics as possible, but the right five to ten, ideally available in real time rather than in a quarterly report.

What Is Procurement Controlling?

Procurement controlling is the systematic planning, steering and control of all purchasing and sourcing activities based on defined KPIs. It makes savings measurable, surfaces risks early and replaces gut feeling with data. That puts it well beyond mere cost control: it is the instrument that turns purchasing from an executing function into a value-creating one.

Its importance is growing noticeably. According to the joint study by BME and entero, around 52 percent of the German companies surveyed had an established procurement controlling function in 2025, clearly more than in previous years. The reason is obvious: every euro saved flows straight into the bottom line. As a result, purchasing is moving closer to the executive level.

Just how big that lever is becomes clear from McKinsey's analysis. Companies that analyze their sourcing data systematically unlock additional savings of 8 to 12 percent of purchasing volume, and with advanced analytics, as much as 15 to 20 percent.

How Do Operational and Strategic Procurement Controlling Work Together?

In practice, two levels work hand in hand. Operational procurement controlling steers the day-to-day business. It keeps an eye on order values, delivery dates, complaints and process costs, working short-term, tightly clocked and aimed at securing ongoing efficiency.

Strategic procurement controlling looks ahead. It assesses the savings ratio over the year, dependence on individual suppliers, contract coverage and procurement's contribution to the company result. This is where the groundwork for make-or-buy decisions and supplier strategies is laid. A sound supplier evaluation based on clear criteria delivers important input data for it.

The two levels interlock: operational data provides the early-warning signals from which strategic decisions grow. Anyone who looks at only one level either treats symptoms or loses sight of the day-to-day business.

In our sourcing projects, we regularly see mid-sized importers focus on operational day-to-day tracking first and only build out the strategic layer later, often once a single supplier failure makes the underlying dependency painfully visible.

Which KPIs Should You Measure in Purchasing?

Which KPIs belong in an effective procurement controlling system? The overview below brings together the metrics most frequently used in practice, separated into operational and strategic steering. As rough orientation, two widely used reference values apply: a maverick buying rate below 10 percent and on-time delivery above 95 percent.

The maverick buying rate is especially revealing: the share of orders that bypass the controlled purchasing process. Just how costly this is becomes clear in The Hackett Group's Maverick Spend Report: leading purchasing organizations source 91 percent of their volume under contract, and as a result lose around 60 percent fewer savings to non-compliance than the average.

One thing to keep in mind: a metric only reveals its value in context. The savings ratio alone says little as long as the calculation baseline stays unclear. Only the combination of several KPIs (for example savings in relation to on-time delivery and complaint rate) shows whether savings are sustainable or come at the expense of quality. Anyone who wants to do the math properly also looks at the full life-cycle costs in the sense of total cost of ownership rather than the purchase price alone.

How Many KPIs Make Sense?

The most common weakness in procurement controlling is not a lack of figures but a surplus of them. Anyone who collects dozens of metrics without prioritizing creates a "metrics graveyard": reports that no one reads because the essentials are lost in the detail.

The recommendation from controlling practice is clear: five to ten metrics that pay directly into corporate goals carry more weight than twenty that merely fake completeness. A mid-sized importer, for instance, does well to focus on savings ratio, on-time delivery, maverick buying rate and contract coverage, rounded out by a metric for supplier dependency.

Three questions help with the selection: Does the metric pay into a concrete corporate goal? Who is responsible for it? And can it be captured reliably with reasonable effort? A metric that no one owns, or that only arises through major manual effort, is in doubt no metric at all.

Why Does Real-Time Procurement Controlling Pay Off?

The greatest lever in modern procurement controlling lies not in new metrics but in when they are available. As long as KPIs are laboriously gathered from spreadsheets once a quarter, steering stays backward-looking: it shows what was, not what is happening right now.

The mid-market is moving here noticeably, as part of a broader digitalization of procurement. According to the "Einkaufsbarometer Mittelstand 2025" by BME and Onventis, around 60 percent of the purchasing departments surveyed have digitalized their procurement processes, with a further 30 percent planning the step. Respondents cite a lack of time and staff as the biggest hurdle.

In practice, we repeatedly observe that the move to real-time metrics rarely fails because of technology. It fails because of data discipline in daily operations: only once orders, delivery notes and invoices are consistently captured in the same system does a dashboard deliver reliable numbers.

That the step pays off is shown by Deloitte's Global Chief Procurement Officer Survey 2025: digitally leading procurement organizations meet or exceed their savings targets 96 percent of the time, compared with just 80 percent for less digitalized competitors. These "digital masters" put up to 24 percent of their budget into technology, almost twice as much as in 2023.

This is exactly where our SCD Dashboard (Supply Chain Digitalization) comes in. It maps the supply chain and the central purchasing KPIs in real time: order status, delivery dates and cost trends are visible at any time, not only in the monthly report. Backward-looking reporting becomes forward-looking steering. Artificial intelligence in procurement, too, only plays to its strengths on such a clean, current data foundation.

What Mistakes Weaken Procurement Controlling in Practice?

Even well-intentioned controlling often fails in practice due to the same patterns:

• Data silos: Purchasing data spreads across ERP, spreadsheets and email inboxes. Without a consolidated data basis, every metric remains contestable. Deloitte names siloed working as one of the biggest barriers to high-performing procurement functions.

• Double-counted savings: Anyone who records savings without a clean baseline and clear scope produces flattering reports that withstand no scrutiny.

• Metrics without owners: Every KPI needs an owner who interprets it and derives measures from it. Without one, the metric stays pure decoration.

• Reporting instead of steering: Collecting figures is not the same as steering. What matters is that deviations lead to concrete action.

Frequently Asked Questions on Procurement Controlling

What is procurement controlling? Procurement controlling is the systematic planning, steering and control of all purchasing activities based on KPIs. Its goal is to make savings measurable and to base decisions on data.

Which KPIs belong in procurement controlling? Central KPIs are the savings ratio, the maverick buying rate, on-time delivery, contract coverage as well as complaint and process costs. A selection of five to ten metrics is advisable.

What distinguishes operational from strategic procurement controlling? Operational controlling steers the short-term day-to-day business: orders, dates, costs. Strategic controlling assesses long-term variables such as the savings ratio, supplier structure and procurement's value contribution.

How many KPIs make sense in purchasing? Five to ten clearly owned and goal-linked metrics carry more weight than an extensive catalogue that goes unused in practice.

Conclusion: Procurement Controlling as a Competitive Advantage

Procurement controlling is neither an end in itself nor a tedious reporting obligation. It is the tool that turns reactive purchasing into a strategic value driver. Two things decide whether it succeeds: the selection of a few genuinely meaningful metrics, and their availability in real time. Companies that invest in clean data and well-designed processes negotiate better, spot risks earlier and secure measurable savings.
