Management consultancy, system house, digital agency or IT consulting: who does what?
Four types of provider, four different bottlenecks. How to tell which one you actually need, why vendor independence is the decisive question, and the three questions that settle it in a first conversation.
Which provider you need depends on where your bottleneck sits. A management consultancy helps with the decision, an IT system house with operations, a digital agency with external presence, and IT consulting with implementation support helps with steering between those worlds. The most expensive misfires happen when a steering problem is handed to someone who sells products.
What you’ll take away:
- Four provider types address four different bottlenecks. The type decides more about project success than company size does.
- The most common misfire: a system house is asked which software fits. It reliably recommends the one it resells.
- Vendor independence is the dividing line between selection advice and sales.
- Three questions in a first conversation reveal the type, regardless of what someone calls themselves.
- If you cannot yet name the bottleneck, a maturity assessment is a cheaper first step than a project.
Which provider do I need for digitalisation?
The one whose core service matches your bottleneck. Four types are relevant in the mid-market, and they overlap less than the self-descriptions suggest.
| Type | Core service | Fits when your bottleneck is | Limit |
|---|---|---|---|
| Management consultancy | Strategy, organisation, process design | The direction is unclear | Usually ends with the recommendation, without implementation |
| IT system house | Procurement, rollout, operations, support | Operations must run and scale | Prefers to recommend what it resells |
| Digital agency | Website, campaigns, content, marketing technology | External presence is the topic | Internal processes and specialist systems fall outside |
| IT consulting with implementation support | Selection, project steering, integration into operations | Nobody is leading the project | Replaces neither operations nor support |
The row most often needed and least often ordered in the mid-market is the fourth. The reason is simple: the first three types are known as a category because they deliver something tangible. Steering is invisible as long as it works.
How do I know which type I need?
By the question that is currently blocking you.
If you do not know what the next sensible step is, you need a maturity assessment and then a decision on direction. If you know what you want but not with which system, you need a vendor-independent selection. If both are settled and the project still has not moved for months, you need steering. And if systems are running but outages and support are the topic, you need a system house.
That mapping sounds obvious and still gets skipped regularly, because the first call usually goes to the provider you already know. That is understandable, and it is also the point where the switch gets set wrong.
Why is a system house the wrong partner for software selection?
Because its business model rests on products. A system house earns on licences, implementation and operation of the systems it holds partnerships for. Ask there which solution fits and you get an honest answer within a predetermined section of the market.
That is not an accusation. A system house that knows its partner products deeply is valuable in operations, and that depth only comes from specialisation. The mistake is handing a selection decision to a party whose selection has already been made.
The practical consequence usually looks the same: a system gets introduced that suits the vendor well and the business moderately. That only becomes visible after two years, when processes have been adapted to the software instead of the other way round.
What does vendor independence mean in practice?
That the consultant earns nothing on any licence they recommend. That is a verifiable statement rather than a question of attitude. Anyone working independently can disclose what they earn on, and does so without hesitation when asked.
How to spot it in conversation: an independent selection starts with your processes and ends with a shortlist that also contains options the consultant does not support themselves. A sales-driven selection starts with a product demo.
A second test is how the existing estate is treated. Independent consulting asks first what is already in place and whether it is sufficient. The answer “your current system can do that, you just aren’t using the feature” is worthless to a sales organisation and frequently the cheapest solution for you.
Which three questions settle the type in a first conversation?
Three are enough, regardless of what someone calls themselves on their website.
First: what do you earn on in this project? Anyone earning on licences or commissions is a sales partner. That can be the right choice, but it has to be known.
Second: what happens after your recommendation? Anyone who ends by handing over a document is a consultancy. Anyone who steers implementation names responsibilities, dates and a handover point into operations.
Third: what if our existing system is already sufficient? The answer to that question is the most reliable indicator in the whole conversation.
Where does PASSION4IT sit?
In the fourth row of the table. Vendor-independent selection and steering through to go-live, without licence business and without running operations. Your system house stays responsible for operations, and that is deliberate, because the two roles have different incentives.
If the bottleneck has not been named yet, the Digital Check is a cheaper entry point than a project. It assesses digital maturity across five dimensions, from strategy through processes and technology to employees’ digital skills, and ends with a prioritised roadmap. The fixed price is 3,950 euros, and the consulting is eligible for BAFA funding; PASSION4IT is registered with BAFA, consultant number 222542.
If the direction is settled and it is only about the right system, smart software selection is the more direct route.
Frequently asked questions (FAQ)
Which provider do I need for digitalisation?
The one whose core service matches your bottleneck: management consultancy for unclear direction, system house for procurement and operations, digital agency for external presence, IT consulting with implementation support for selection and project steering. The type decides more about success than company size.
What is the difference between IT consulting and an IT system house?
A system house procures, implements and operates systems it holds vendor partnerships for, and earns on licences and operations. Vendor-independent IT consulting selects and steers the project without earning on any recommended licence.
Can a system house handle software selection?
It can give a well-founded recommendation within its partner portfolio. For an open selection it is structurally the wrong partner, because its business model rests on particular products. That is a question of incentives rather than a judgement on quality.
How do I recognise vendor independence?
By the consultant disclosing what they earn on, by the selection starting with your processes instead of a product demo, and by the shortlist also containing options they do not support themselves.
Which questions should I ask in a first conversation?
What do you earn on in this project, what happens after your recommendation, and what if our existing system is already sufficient? The third question is the most reliable indicator.
Do I need a digital agency for internal processes?
Usually not. Digital agencies are built for external presence, meaning website, campaigns and marketing technology. Internal specialist systems, interfaces and process integration sit outside their core.
What does the entry point cost if I don’t know the bottleneck yet?
The PASSION4IT Digital Check costs 3,950 euros at a fixed price and assesses digital maturity across five dimensions, producing a prioritised roadmap. It is eligible for BAFA funding, with consulting costs subsidised up to an assessment base of 3,500 euros per engagement and the rate depending on location.
Can I combine several types?
Yes, and in ongoing operations that is the normal case. The usual combination is vendor-independent steering during the project and a system house for operations and support afterwards. What matters is a defined handover point.
