In industrial companies, the analytical and operational focus of purchasing has traditionally been on direct materials. Indirect purchasing – that is, expenditures for services, operating resources, C-parts , IT accessories, marketing, travel, or special requirements – is often considered secondary. This attitude is dangerous. Although indirect purchasing typically accounts for 15–30% of the purchasing volume, it generates up to 60% of operational transaction costs in purchasing for many companies.
Recent studies further underscore the strategic relevance: In indirect procurement can account for up to 50% of total procurement volume in Fortune 500 companies. In German medium-sized enterprises, the average indirect procurement volume is €31.4 million annually, while for large corporations it reaches €232.8 million. These figures highlight the enormous financial potential that often remains untapped in this area.
Professionally managed expenditure control in this area is therefore not an administrative nice-to-have, but a substantial lever for cost control, process stability and risk minimization – especially against the backdrop of increased requirements for compliance, efficiency and liquidity management.
| Cost category | range | Example of annual impact |
|---|---|---|
| Maverick purchase bonus | 10–20% loss in savings | €2–4 million out of €20 million in expenses |
| Additional transaction processing | $2.58 per $1,000 spent | €51,600 out of €20 million in expenses |
| Lost quantity discounts | Framework agreement discounts | €200,000–€500,000 potential |
| Compliance risk costs | Examination/penalty costs | Potential value of €100,000 to €1 million+ |
| administrative effort | > 1 hour per transaction | Over €120,000 (2,000 transactions) |
Indirect procurement is often characterized by heterogeneity and fragmentation. Orders are placed decentrally, processes are rarely standardized, and suppliers are involved without strategic selection. As a result, maverick buying —procurement outside of defined processes—is commonplace. The procurement organization loses control over volumes, supplier terms, and contractual frameworks. Expenditures escape analysis, and budgets cannot be reliably managed.
The scale of the problem is dramatic: In Germany, the average maverick buying rate is 25.6%, meaning that more than a quarter of all procurement takes place outside of established processes. International studies show that maverick buying can account for up to 80% of procurement volume, with companies losing 10-20% of their potential savings due to uncontrolled procurement.
The financial impact is considerable: With an average maverick buying rate of 2% or more, additional procurement costs of $2.58 are incurred for every $1,000 spent. For a company with €20 million in annual indirect purchasing volume, this translates to additional costs of over €51,000 due to inefficient transaction processing alone.
Typical symptoms of poor expenditure management in indirect procurement include:
This operational inefficiency counteracts any purchasing strategy – no matter how efficiently direct purchasing is organized.

Effective spend management in indirect procurement aims to centrally record and analyze all expenditures and control them accordingly. Operational implementation requires a combination of organizational standardization, intelligent tool support, and clearly defined roles within the procurement process.
The digitalization of procurement is gaining significant importance: German companies plan to achieve a digitalization rate of 70% in procurement by 2027, with average annual investments of €1.2 million in the digitalization of their procurement processes. The German market for procurement software is growing at an annual rate of 12.5%, underscoring the high priority of digital solutions.
Specifically, professional expense management includes:
The transition to such a target model can be done gradually – e.g. via an intelligent interim solution such as the single-creditor model.
The success of professional spend management depends not only on data analysis, but above all on the operational implementation of concrete control measures. Three approaches have proven particularly effective in industrial practice: framework agreements with service providers, negotiated catalogs with OCI integration, and the single-vendor model. They complement each other and enable a tiered control model across different demand types.
For regularly recurring services – such as facility services, maintenance, waste disposal, or IT services – framework agreements are the preferred option. They not only ensure price stability and legal certainty, but also the systematic management of the scope of services, quality, and billing.
Advantages from a purchasing perspective:
Framework agreements should be applied in indirect procurement not only to strategically important services, but also to service types that are cost-intensive. Usage can be tracked in the form of call-offs or quotas – ideally digitally supported and linked to a budget.
For standardized consumer goods (office supplies, workwear, IT accessories, consumables), negotiated catalogs with direct system integration are an established management tool. External catalogs can be directly integrated into the ERP system via so-called OCI PunchOut interfaces (Open Catalog Interface) – with automatic transfer of the items back into the ordering process.
The acceptance of e-procurement is growing steadily: In 2022, over USD 1 trillion was transacted worldwide via e-procurement platforms, and 51% of companies already use e-procurement platforms for their orders. These figures demonstrate the growing importance of digital procurement solutions.
Benefits from a purchasing management perspective:
However, the effort required to maintain and integrate such catalogs should not be underestimated – both on the supplier side and in IT. Therefore, this approach is primarily economically viable with high transaction volumes and consistent demand.
For irregular, difficult-to-standardize requirements – such as special tools, spare parts, technical literature, or individual devices – traditional e-procurement structures reach their limits. Here, the single-vendor model, as implemented by providers like FACURA, offers a highly flexible and, at the same time, process-reliable solution.
The importance of outsourcing solutions is growing exponentially: The market for indirect procurement outsourcing has grown from $5.7 billion in 2024 to a projected $10.2 billion by 2033, representing an annual growth rate of 7.2%. This underscores the increasing demand for external solutions to complex procurement requirements.
How it works:
Advantages for shopping:
The single-vendor model is particularly suitable where flexibility is required, but centralized control and budget transparency are still desired. It effectively bridges the gap between strategic purchasing planning and operational demand fulfillment. Efficient handling of special requests frees up more time for optimizing expenditures across large product groups and suppliers.
Summary of the collection of methods:
The combination of framework agreements, catalog integration, and a single-vendor model allows for differentiated control of indirect procurement based on demand type. While standard and recurring demands can be controlled through integration and standardization, the single-vendor model also enables the inclusion of atypical, special demands – without compromising compliance, data quality, or cost transparency. This transforms expenditure management into a fully operational control instrument for indirect procurement.
Transparency alone is not enough – it is a necessary but not sufficient condition for effective expenditure management. Only when transparency is consistently integrated into operational control mechanisms does it unfold its full potential. The central goal is to make data-driven decisions, effectively monitor budgets, and identify deviations early on.
Indirect procurement places specific demands on controlling. Unlike direct procurement, there are rarely bills of materials, demand forecasts, or contracts relevant to final agreements. Instead, flexible requirements, individual decisions, and decentralized requesting departments dominate – all factors that make budget discipline and cost tracking more difficult.
The costs of inefficient processes are considerable: The average cost per order in the industry is €45-59, and across all sectors it is as high as €163-217. Companies with higher maverick buying rates require a median of 16 hours more for order processing, which underlines the importance of structured processes.
An effective control model is based on three levels:
A key success factor is the standardization of data formats: Only when all purchasing documents (invoices, order confirmations, delivery notes) are structured uniformly can this information be processed automatically without manual corrections. Solutions like FACURA address this directly by providing standardized documents regardless of the originating supplier – a fundamental building block for accurate reporting and reliable analysis.
In many companies, requirements for indirect procurement are communicated informally – via email, telephone, or verbally. This leads to inconsistencies, incompleteness, and high coordination costs. Simply introducing a standardized digital form – ideally as a purchase requisition within the ERP system – for requirements notifications, with mandatory fields for purpose, category, budget allocation, and urgency, can create the following advantages:
This template can be set up in just a few hours using existing tools (e.g., an internal SharePoint or form tool). It is a simple yet effective step towards greater organization and transparency.
Especially for sporadic, non-standardized needs – from special tools and spare parts to customized services – the effort required for vendor setup, invoice verification, and approval is disproportionately high. FACURA’s single-vendor model offers an immediately deployable solution:
Advantages at a glance:
FACURA is therefore an ideal tool for establishing structured, centralized control of indirect procurement on an ad hoc basis – while simultaneously maintaining operational agility. This saves procurement departments time to focus on the major spending drivers.
Professionalizing spend management in indirect procurement is not a technical project – it is a strategic management task. Transparent, controllable, and systemically integrated processes not only create savings but also improve compliance, reduce risks, and relieve procurement of operational complexity.
The figures speak for themselves: German industrial companies can save up to €100 billion through intelligent material cost management, while 87% of German manufacturing companies have already adapted their procurement strategies in response to supply chain disruptions. The demand for procurement specialists is growing by 6% annually, underscoring the strategic importance of professional procurement.
Recommendation: Examine the spending structure of your indirect procurement. Identify maverick buying rates, transaction costs, and supplier diversity. And create a new level of procurement management with standardized, digitally supported processes – for example, via scalable solutions like FACURA.
The time for half-hearted solutions is over. In light of rising costs, more complex supply chains, and stricter compliance requirements, professional spend management in indirect procurement is no longer optional, but vital for the competitiveness of industrial companies.
