Influencer Marketing In-House or With an Agency? An Honest Comparison
Updated on 11 November 2026
Running influencer marketing in-house makes sense if you work with only a few creators, someone on your team has regular time for it and you want to build the knowledge internally. An agency makes sense when several creators run at once, when contracts and usage rights need to be properly settled or when you lack capacity. In between are hybrid models, which suit many brands best.
What does an influencer campaign actually involve?
The workload is almost always underestimated because only the finished post is visible. Behind it are these tasks:
- define goal, audience, budget and timing
- research and vet creators
- approach, follow up, negotiate
- settle the contract and usage rights
- write the briefing
- ship products and keep to dates
- review and approve drafts
- check ad disclosure
- accompany publication and keep an eye on comments
- collect and evaluate the figures
- check and pay invoices
With one creator that is manageable. With eight creators on different schedules it becomes a job of its own.
What speaks for doing it yourself?
- Closeness. You talk to the creators directly. That builds relationships that last beyond one campaign.
- Knowledge stays in-house. You learn which profiles, formats and messages work for your brand.
- No agency fee. The budget goes into creators and content. You invest your own working time instead, and that belongs in the calculation.
- Short lines. Decisions are made without an intermediary.
For it to work you need one person with dedicated time – not “on the side” – templates for contract and briefing, and a clear approval route. The basics are in our articles on how to find influencers and contract and briefing.
What are the risks of going it alone?
- Choosing by gut feeling. Without comparison, every likeable profile seems to fit. Only the analytics show whether the followers are your audience.
- Fees without a benchmark. If you rarely negotiate, you don’t know what is customary – and either overpay or put off good creators with low offers.
- Gaps in the rights. If a video is to run as an ad later, that has to be agreed beforehand. Renegotiating costs more.
- Missing disclosure. If a post is not labelled as advertising, it reflects on your brand too. The basic rules for the German market are in our article on ad disclosure.
- Dependence on one person. If your colleague is ill or changes jobs, contacts and experience leave with them.
- No plan B. If a creator drops out shortly before the date, you need a replacement fast. Without a network that is difficult.
What does an agency bring – and what doesn’t it?
An agency brings experience from many campaigns, personal contacts with creators, a benchmark for fees and established routines for contracts, approvals and reporting. It can manage several creators in parallel and has alternatives when someone drops out.
What it does not take off your hands: you still have to set the goal and the budget, provide a good briefing on the brand, give approvals promptly and name someone internally who decides. An agency costs money and adds one more party to the coordination. And at the start it knows your product less well than you do. Our article on how to choose an influencer marketing agency explains what to look for.
When does which option fit?
In-house fits if
- you work with one to three creators, ideally long term,
- someone on the team has dedicated time and an interest in the subject,
- the planned use of the content is limited,
- you want to gain experience before planning bigger.
An agency fits if
- several creators or several platforms run at the same time,
- a fixed date such as a launch has to be met,
- content is also to be used for ads, your shop or retail,
- well-known faces or longer partnerships are planned,
- nobody on the team has lasting time for it.
Which hybrid models are there?
It doesn’t have to be all or nothing:
- Selection external, day-to-day internal. The agency supplies vetted suggestions and negotiates; your team runs the ongoing collaboration.
- Start with an agency, then take over. The first campaign runs entirely externally. You keep the templates, routines and lessons afterwards.
- Everyday internal, projects external. You look after lasting collaborations with a few creators yourself and bring in support for launches and larger campaigns.
- Buy content only. If you mainly need videos for ads and your shop, UGC content is a separate, easily planned solution.
With any hybrid model, put in writing who is responsible for what. Otherwise nobody feels in charge of disclosure and reporting in the end.
How do you compare the two honestly?
Don’t set the agency fee against zero. On one side, count the internal hours for research, negotiation, coordination and evaluation, plus tools and the time that is missing elsewhere. On the other side are the agency fee and the effort that stays with you anyway. Include risk in both calculations: what does it cost if a date slips, rights are missing or a post has to be produced again? Often the decision is then not for good, but for the next campaign.
Checklist: in-house or agency?
- How many creators are to run at the same time?
- Who on the team has fixed hours per week for this?
- Do you have templates for contract and briefing?
- Do you know which fees are customary in your category?
- Is the content also to be used as an ad or in your shop?
- Is there a fixed date that must not slip?
- Who checks ad disclosure?
- Who steps in if the person in charge is unavailable?
- What does internal working time cost compared with an agency fee?

Frequently asked questions
Yes. With a few creators, one person with dedicated time and templates for contract and briefing, influencer marketing can be handled well in-house. The work lies less in the individual post than in research, negotiation, approvals, checking disclosure and evaluation.
An agency is worth it when several creators or platforms run at once, a fixed date has to be met, content is also to be used for ads, well-known faces are planned or your team lacks capacity.
Typical risks are choosing by gut feeling rather than by audience, fees without a benchmark, usage rights that were never agreed, missing ad disclosure and dependence on a single person on the team.
Yes. Hybrid models are common: the agency handles selection and negotiation while your team looks after the ongoing collaboration. Or you manage lasting partnerships yourself and bring in support for launches and larger campaigns.
Set the goal and the budget, provide a good briefing on brand and product, approve drafts promptly and name one person who decides. No agency can take those tasks off your hands.
