When a company starts a transformation, gets into a crisis, grows strongly or leaves a central management function unfilled, it quickly faces the key question: interim management or management consultancy? This is precisely where it is decided whether an organization gains speed or loses time. While a management consultancy primarily develops analyses, concepts and strategies, an interim professional takes responsibility for day-to-day operations and makes decisions that take immediate effect. Despite these two options, the idea that you have to choose between external consulting and complete in-house services persists in many places. In SMEs in particular, this misconception leads to valuable potential remaining untapped - in an environment characterized by a shortage of resources, high implementation pressure and busy schedules. Those who rely exclusively on external analyses run the risk of good concepts not finding their way into implementation. The key question is therefore: Which setup suits our situation: interim management or consulting?
What does an interim professional do, what does a management consultancy do?
Before we start talking about daily rates, durations or project plans, we need a clear picture of what interim management does and what tasks a management consultancy actually takes on. Many discussions revolve around costs and names, although the decisive factor is the role: who analyzes, who decides, who implements, who bears responsibility? This is the real difference between interim management and management consultancy.
Interim management in practice: what does an interim manager do?
In practice, interim management means that an experienced specialist or manager joins the organization for a limited period of time and takes on a clear mandate - with line responsibility, with a team, with goals. Whether as managing director, in divisional management or in programme management: an interim professional makes decisions in day-to-day business, prioritizes tasks, manages budgets and is responsible for results.
According to the DDIM Market Study 2024, the most important characteristics of interim professionals include the following:
- Implementation skills
- Competence in change management
- Leadership skills
- Experience in dealing with crises
- Breiter Erfahrungsschatz
- Specific project experience
- Kommunikationskompetenz
- Erfolgsorientiertes Mindset
- Expert and methodological knowledge
- Lack of power or career interests

Whoever asks themselves, "What does an interim manager do?", rarely gets an academic answer, but a very practical one: identify problems, make decisions, implement measures, lead teams. Interim managers are not observers, but part of the system - with access to the relevant information, a view of the overall value creation and the expectation that key figures will improve noticeably within the mandate.
Typical fields of application for interim management are:
- temporary assumption of a management function
- management of critical projects (for example ERP implementation, restructuring, Carve-out)
- Stabilization of areas, where management is currently lacking
Definition of interim management
Interim management is the temporary assignment of an experienced specialist or manager who immediately assumes operational responsibility, makes decisions and implements measures in day-to-day business. The aim is to achieve results, stabilize structures or drive change within a defined mandate period.
Corporate consulting in practice: what does a management consultancy do?
A corporate consultancy works differently. Consultants rarely intervene in the line organization, but work in projects "on" the system: they analyse markets, structures, processes, organization and finances. In addition, management consultants develop concepts and strategies, create benchmarks and recommendations for action.
Whoever asks, "What does a management consultancy do?", you typically get answers like:
- market and competition analyses
- Strategieentwicklung
- Organisationsdesign
- Cost analyses
- Restructuring concepts
The role is strongly analytical and conceptual in nature. Consultants contribute methodological expertise, industry knowledge and best practices - and provide a basis for decision-making, scenarios and recommendations for company management. The involvement is usually project-related with a clearly defined scope and a fixed term. In many cases, however, responsibility for implementation in day-to-day business remains with the core organization - or with an interim manager who puts the consulting project into practice.
Definition of management consulting
Management consulting is the analytical and conceptual support of companies by external experts. They analyse markets, organization and processes, develop strategies and recommendations for action and provide structured knowledge and benchmarks - without assuming operational line responsibility in day-to-day business.
Interim management vs. management consulting: the differences at a glance
At first glance, both approaches seem similar: external support, time-limited, clearly defined mandate. However, there are three key differences:
- Degree of responsibility
A management consultancy makes recommendations, an interim professional makes decisions. Consultants deliver concepts, interim managers are responsible for their implementation - including the consequences. - Proximity to day-to-day business
Consultancies usually work in project structures, workshops and analyses. Interim management, on the other hand, takes place in the middle of the operational business: in production, in sales, in IT, in corporate management. - Time horizon and entry
A consultancy usually starts with a project assignment, a scoping phase and a team set-up. An interim professional can often start within a few days and immediately take over an existing role - including management of employees, budget and profit responsibility.
| Criterion | Interim Management | Corporate Consulting |
|---|---|---|
| Degree of responsibility | Make decisions, lead teams, implement measures, take responsibility for results | create analyses, develop concepts and recommend measures without assuming direct responsibility |
| Operative proximity | Work in the operational environment with a focus on immediately effective measures: Production, sales, IT, corporate management | Work "on" the system without involvement in day-to-day operations: create analyses, concepts and benchmarking, conduct workshops |
Time horizon | Start within a few days, direct assumption of a management role with budget and personnel responsibility | project start with scoping, team setup and analysis phases; recommendations are developed over defined project durations |
Once you understand these differences, you quickly realize that it's not about "better or worse", but about the right tool. Interim management is strong when leadership, decision-making competence and implementation are required. Corporate consulting shows its strength when the focus is on analyses, concepts and strategic decisions - ideally in combination with a manager who is responsible for implementation.
At a glance
Interim managers take on operational responsibility and implement measures.
Corporate consultants provide analyses, strategies and structured recommendations.
The main difference lies in the proximity to day-to-day business, the decision-making authority and the responsibility for implementation.

Speed, implementation power and decision-making authority: interim management vs. management consultancy
Interim management creates immediate ability to act. An interim professional can often start within a few days. This is an advantage if a department is without leadership, a project is stuck or the performance of a department collapses. Companies are immediately assigned a person who makes decisions, implements measures and shows ways out of the crisis.
Corporate consultancies require more lead time. A consulting project starts with an offer, scoping and team composition. This process creates structure, but takes time. Management consulting is therefore particularly suitable for plannable projects, not for acute crisis situations.
What impact does an interim manager have on day-to-day business?
An interim professional directly assumes operational responsibility. This means:
- making decisions
- Teams führen
- Maßnahmen priorisieren
- Stabilize processes
- Take responsibility for goals
This effect is immediately felt within the company. It is directly noticeable and improves the situation in day-to-day business.
When is speed crucial?
- When production output collapses and delivery deadlines are at risk
- When a division manager is absent at short notice.
- When a transformation project is stuck
- When a reorganization or a carve-out requires operational management.
In these situations, Interim Management is the fastest and most effective form of external support.
What effect does a management consultant achieve?
A management consultancy provides structure and analysis. It develops strategies, benchmarks, target images and programs. The impact unfolds in the depth of content and methodological quality. Consulting provides orientation for important decisions. However, implementation is usually not carried out by the consultancy itself.
Why and where does an implementation gap arise?
Corporate consultancies develop concepts.
Interim professionals implement concepts operationally.
There is always an implementation gap when a company knows in theory what needs to be done, but no one takes responsibility for implementation. This gap arises particularly in projects such as:
- Restrukturierungen
- Prozessoptimierungen
- Digitalisierungsinitiativen und ERP-Programmen
- Organizational development
At a glance
Interim Professionals start within a few days and stabilize day-to-day business.
Corporate consulting requires lead time for analysis, project definition and team building.
Interim management has an immediate effect, while consulting structures long-term decisions.
Comparing the costs of interim management and corporate consulting
When CFOs and HR managers think about external support, one of the first questions is almost always: What does it cost us - and what do we get in return? However, simply looking at the daily rate of interim professionals or the cost of a management consultancy falls short of the mark. The decisive factors are how remuneration models work, what hidden costs arise and who actually takes responsibility for results in the end.
Interim managers: daily rate
In interim management, companies usually work with daily rates. The daily rate of an interim manager depends on the function, the scope of responsibility, the industry and the complexity of the mandate. Other factors include the duration and workload: full-time mandates in critical phases differ from partial assignments, where an interim professional works around two to three days a week.
The individual daily rate is less important here than the logic behind it:
- The company pays for a clearly defined role with operational responsibility.
- The costs can be planned transparently and end with the mandate.
- Social security contributions, employer risks and long-term obligations are eliminated.
- Interim professionals have no entitlement to vacation or Christmas bonuses.
Whoever uses the costs of interim management, you should always consider what internal alternatives are realistically available . On the other hand, the question must be answered as to how much it would cost the company if a key position remained unfilled or a project continued to stall.
In SMEs in particular, an unfilled management position or a slow-moving transformation project can be significantly more expensive than a seemingly high daily rate.
In 2024, the average daily rate for interim management was just under €1,340, according to the AIMP.

Compensation models in management consulting
Other models dominate in management consulting: project flat rates, phase fees or retainer models. A team with different seniority levels is often deployed - from junior to project management to partner level. While a junior consultant, according to BDU study "Fees in Consulting 2025" has a daily rate of around 1,350 euros, a partner costs an average of 2,550 euros per day (source: Bundesverband Deutscher Unternehmensberatungen BDU e.V.). For CFOs, this means:
- The cost of management consulting depends on the project scope, duration and team size.
- Analyses, workshops, strategy papers and presentations are clearly defined.
- In many cases, responsibility for operational implementation remains with the company.
A management consultancy makes economic sense if analysis, strategy and a structured approach are required above all - and there is sufficient internal capacity to implement the recommendations independently at a later date.
At a glance
Interim management is based on daily rates with clear operational responsibility.
Corporate consulting works with project or phase fees and provides conceptual services.
The decisive factors are not the daily rates, but responsibility, time factor and overall economic benefit.
Interim management vs. Management consulting: realistically evaluating benefits and ROI
In the end, the comparison between interim management and consulting usually comes down to two key questions:
- What results does the company need and when?
If rapid stabilization, decision-making power and implementation are required, there is a lot to be said for interim management with clear responsibility for results. When it comes to market assessment, strategy development or organizational design, a management consultancy is the right instrument. - Who is responsible if something goes wrong?
An interim professional vouches for the implementation and assumes responsibility in the operational business. A consultancy is responsible for the quality of the analysis and concept - but not for the day-to-day decisions in the company.
Those who answer these questions properly will no longer just be making a decision about "daily rate for interim managers" or "cost of management consultancy", but about the most economically sensible approach for their own situation.
Typical use cases: Differences between interim management and management consulting
Companies rarely make a gut decision between interim management and consulting. The decisive factor is specific situations in which either operational responsibility or analytical depth is required.
When does interim management make sense?
Interim management comes into its own when quick stabilization, leadership and implementation are required. The following scenarios show why interim professionals are often the most effective option, especially in SMEs:
Vacancy bridging
- Challenge: A key management position becomes vacant at short notice.
- Lösung: Interim management makes sense because an experienced manager steps in immediately and assumes operational responsibility.
Crisis management
- Challenge: A company is in a crisis, a restructuring phase or a turnaround.
- Solution: Interim management in a crisis ensures that decisions are made quickly, processes are stabilized and measures are implemented consistently.
Transformation
- Challenge: A critical transformation project is at risk of failing - for example an ERP implementation, a carve-out, a site closure or the establishment of a new location.
- Lösung: Interim Transformation Management creates clarity, prioritizes measures and leads teams through complex change phases with the help of professional Change Management.
Business Development
- Challenge: An area needs to grow or scale in the short term - for example in production, sales or service - but there is a lack of internal capacity or management experience.
- Lösung: Interim management makes sense because an external manager creates structures, strengthens teams and manages growth in a controlled manner.
In all these cases, it is about taking responsibility, implementing measures and achieving impact in day-to-day business - typical areas of application in which interim professionals deliver results even before an analysis process could begin.
When does management consulting make sense?
Corporate consulting is particularly useful when companies need orientation, analytical depth and a structured view from the outside. This applies above all to market and competitive analyses, the development of new strategies, business models or pricing approaches, as well as the need for benchmarks and best practices. In these situations, consultancies provide clear data, comparisons and methodologically sound concepts that serve as the basis for strategic decisions. The focus is less on day-to-day operations and more on conceptual preparation for future developments and trend-setting decisions.

Decision guidelines: Five questions to find the right solution
When companies are choosing between interim management and management consultancy, professional criteria help them make an informed decision. The following checklist is a valuable aid.
Do we need analysis or implementation - or both?
If analytical depth and market knowledge are the main focus, there is a lot to be said for consulting. However, when decisions, leadership and implementation are required, interim management offers clear advantages.
Does someone in the company have to make decisions and take responsibility?
Interim professionals bear operational responsibility and make decisions in day-to-day business. Consultancies provide recommendations - the decision lies with the company.
How critical is the time factor?
In acute situations, such as vacancies, crises or project standstills, interim management is usually the much faster solution. Strategic issues leave more time for consulting projects.
What internal resources can we provide?
If employees are working at full capacity, consulting can come to nothing because no one can take on the implementation. Interim professionals provide direct relief in operational business.
What risks do we want to reduce?
Interim management is primarily used to minimize implementation and management risks. Management consulting, on the other hand, reduces analysis and decision-making risks.
This decision-making guide quickly makes it clear: in many practical cases - especially when responsibility, speed and implementation are crucial - interim management is the pragmatic and economical way to go. To help companies find the right solution, specialized interim management providers provide support in the selection of tested, experienced interim professionals. The focus here is not on "interim at any price", but on a tailor-made appointment that fits the respective challenge of the company.

FAQ: Interim management vs. management consultancy
What does an interim manager do?
An interim manager takes on a specialist or management role for a limited period of time with full responsibility for results and often personnel. He or she makes decisions in day-to-day business, stabilizes processes and consistently implements measures - for example in crises, transformations or vacancies.
What does a management consultancy do?
A management consultancy analyses markets, organization and processes and develops strategies, concepts and recommendations. It provides structure, benchmarks and a basis for decision-making, but does not usually take on any operational line or implementation responsibility.
What does interim management cost?
Interim management is usually remunerated via daily rates, the amount of which depends on the function, responsibility, industry and duration of the mandate. The company only pays for the actual assignment time, without long-term ancillary personnel costs.
What is the daily rate for interim managers?
The daily rate for interim managers is typically in the four-figure range per day. According to the AIMP Market Study 2024/25, the average interim management daily rate in the DACH region is around €1,340.
What does a management consultancy cost in the SME sector?
The costs of a management consultancy in the SME sector depend on the project scope, duration and team structure. According to the BDU study "Fees in Consulting 2025", daily rates - depending on seniority - are roughly between a good 1,000 and over 2,500 euros per day, usually bundled into project or phase fees.
When does interim management make sense?
Interim management is useful when rapid stabilization, leadership and implementation are required - for example in the event of vacancies in key positions, crises, turnaround situations, faltering transformation projects or rapid scaling requirements in areas such as production, sales or service.
When is management consulting useful?
Management consulting is useful when companies require analytical depth, market and competitive analyses, new strategies or reliable benchmarks. The focus is then on analysis, conception and long-term orientation - less on operational implementation in day-to-day business.
