Hiring a consultant: interim, freelance or recruitment?

Once you know which type of consultant you need, the main question remains: in which form do you bring them in? That choice drives cost, speed, mandate and what stays behind when the assignment ends. Below are the four routes and the situations where they work.

Freelance: one defined assignment

A freelancer delivers a clear result with their own way of working: an advice, an audit, a dashboard, a campaign. You keep control and coordination.

Works well when: the question is clear, one discipline is enough and you can steer yourself. Does not work when: there is nobody internally giving direction. More on hiring a freelance specialist.

Interim: someone takes over a role

With interim someone temporarily fills a position in your organisation, mandate included: joining meetings, steering, deciding within an agreed budget.

Works well when: a gap opens through departure, illness or leave, or when a team mainly executes and lacks senior steering. Does not work when: you do not want to hand over decision space — then you pay a high rate for someone waiting for approval.

Recruitment: the knowledge stays in house

If the need is structural, hiring in is more expensive long term than hiring. We help with the profile, the assessment and sometimes with looking over their shoulder in the first year, so a new specialist is not thrown in at the deep end.

Works well when: the work is permanent and you have enough volume to both fill and develop a role.

An agency: several disciplines, one point of contact

When different specialisms are needed at once — strategy, technology, content and advertising, for example — one party with a team is more practical than four separate people. That is what we do daily; see our services.

How to select a consultant

1. Describe the decision, not the role. "We must choose between staying on WordPress or migrating" is a brief. "We are looking for a digital consultant" is not.
2. Ask about work, not tools. What did someone do themselves, at which organisation, with what result and what went wrong?
3. Test against your context. Experience in B2B with a long sales cycle is different from a D2C shop with 40,000 sessions a month.
4. Let them work through your question in the conversation. Not as a free pitch, but to hear how someone thinks and which questions they ask.
5. Agree a short first phase. A baseline with a go/no-go decision after. That keeps the risk small.
6. Arrange an owner on your side. Someone with time and mandate, otherwise the advice sits still.

What to agree up front

• Assignment and result — what is in place at the end and what does 'done' look like?
• Mandate — which decisions may they take, up to which budget?
• Hours and availability — days per week and reachability, holidays included.
• Form and terms — how you settle up, travel time, extra rounds and notice period.
• Ownership and access — everything in your accounts and environments. Data, documents, ad accounts and source code are yours.
• Confidentiality and processing — an NDA and, where personal data is involved, a processor agreement.
• Handover — who takes it over, and what must be documented?

We are happy to think along about the contractual form (assignment, secondment or a temporary contract), but we are not a legal advisor. When in doubt, have the form reviewed by a specialist.

Where it usually goes wrong

• The question is not sharp, so the advice could mean anything.
• Nobody owns it internally, so the advice sits on a shelf.
• Mandate and expectations are not written down anywhere.
• No evaluation moment is agreed, so adjusting feels like blaming.
• The handover is only thought about once the assignment is nearly done.

Frequently asked questions about hiring consultants

What if the consultant turns out not to fit?

Agree an evaluation moment up front and write down what happens then. That way you can stop or find someone else without being stuck halfway.

Can one consultant cover several roles?

Partly. Combining advice and delivery works well. Advising and then supervising the same thing — setting up privacy and then filling the DPO role — conflicts; better to separate that.

How much time does it cost me?

More than you think: making decisions, arranging access, reviewing and bringing your team along. Skip that and the engagement slows down.
