Influencer Agency vs Influencer Platform vs In-House: How to Choose

The three models compared

There are three basic ways to run influencer marketing: a full-service agency that does the work for a fee, a self-serve platform that gives you the tooling while you keep the strategy, or in-house/manual, where your own team handles it without specialised software. None of the three is universally "best" — each fits a different combination of budget, internal capacity, and how many collaborations you're running at once.

How each option actually works

Full-service agency

An agency takes on most of the work: sourcing and vetting influencers, negotiating terms, briefing, following up, and reporting. You keep overall ownership of objectives and budget, but day-to-day execution sits with the agency. It's the most expensive per collaboration, but requires the least internal time — valuable when you're short on either capacity or experience to run it yourselves.

Self-serve platform

A platform gives you the structure — per-creator tracking links, briefs, a status overview, payment — without taking the strategy off your hands. You still find and choose the influencers yourselves (see how many influencers you need for a campaign), but you skip building tracking and follow-up in a spreadsheet. It's typically the model that gives the most control per krone, if you have someone who can spend a few hours a week on it.

In-house / manual

Pure manual operation — DMs, spreadsheets, email — works fine for the first handful of collaborations. The problem isn't that starting this way is wrong; the problem is that it breaks down quietly as the number of creators grows. See why manual influencer marketing becomes messy for the specific symptoms and where the threshold usually sits.

How agencies typically charge

Agencies typically use one of three fee models, or a combination:

• Monthly retainer. Covers the agency's time — strategy, sourcing, outreach, negotiation, running the programme, and reporting — not the payments to influencers themselves.
• Project fee. A one-off amount for a defined campaign with a clear start and end date. Common for product launches and seasonal pushes.
• Percentage of spend. The agency takes a cut of the total spent on influencer collaborations and, sometimes, paid distribution. This ties the agency's earnings to how much you spend — not necessarily to how well it performs, which is worth keeping in mind when negotiating.

The exact numbers vary widely by agency, market, and scope. Treat them as something to negotiate and pin down in a contract for the specific engagement, not as an industry standard. See what to put in an influencer contract for the terms that should be written down regardless of which model you choose.

Decision framework: which model fits you?

• Fewer than 5 concurrent collaborations, still validating the channel: Start manual. Don't spend money on structure before you know whether the channel works for you.
• Growing volume, and you want to keep ownership of data and creator relationships: A platform gives you the structure without handing over the strategy.
• No internal marketing capacity, or a large one-off campaign with a tight deadline: An agency solves it fastest, for a higher fee.
• Multiple markets, complex negotiation, or very limited internal time — even at high volume: An agency, or a hybrid of agency and platform.

What it actually costs: an illustrative worked example

The figures below are illustrative, built to show how the cost splits between the fee and internal time — they are not actual agency or platform prices. The example assumes a brand running 15 concurrent creator collaborations a month, and an internal hourly cost of DKK 400.

At this illustrative volume, the platform is cheapest, because the software removes a large share of the time-consuming tracking and follow-up without costing a full agency retainer. The agency is the most expensive in kroner, but demands the least of your own time. The manual track looks cheap until you count the internal time — exactly the trap manual influencer marketing describes. At lower volume (say, 3-4 collaborations), the picture flips: the internal time manual work takes is low enough that neither an agency nor a platform is justified yet.

The hybrid reality

In practice, many brands change models over time, or combine them. A common path: start manual to validate the channel, move to a platform once volume outgrows what a spreadsheet can carry (see how to build an always-on influencer and UGC system), and bring in an agency for specific, time-boxed activations — a product launch, a major seasonal push — without giving up the platform as the day-to-day foundation.

Common mistakes

• Hiring an agency before the channel is validated. An agency retainer pays for execution at scale — not for finding out whether influencer marketing fits your product at all.
• Staying on the manual track too long. See the symptoms in why manual influencer marketing becomes messy — once two or three of them hit at once, the constraint is operational, not strategic.
• Underestimating the internal time a platform still requires. A platform removes the tracking and follow-up work, not the sourcing and relationship work.
• Assuming "percentage of spend" is always cheapest. That model ties the agency's earnings to your spend, not to the outcome.

Make Influence's take

It's our experience — not an objective truth — that most brands underestimate how much control they give up by going straight to a full-service agency, and how much structure they can get without it by using a platform instead. We built Make Influence because we saw the gap between "hand it all to an agency" and "run it in a spreadsheet until it breaks" as a false choice. A platform can give you most of the structure — per-creator tracking, briefs, a status overview — without handing over the strategy.

FAQ

Is a platform always cheaper than an agency?

Not necessarily — it depends on what your internal time is worth and how many collaborations you're running. At low volume, an agency's fixed fee can cost more than a platform fee plus internal time; at very high volume or complex execution, an agency's scale can make it relatively cheaper per collaboration.

Can you switch models later?

Yes, and most brands do. The most common path is manual → platform → occasionally an agency for specific activations, as volume and complexity grow.

Is in-house the same as manual?

No. In-house means your own team runs it — that can happen on a platform just as easily. "Manual" specifically means without specialised tooling, typically in spreadsheets and DMs.

Does a hybrid setup make sense for a smaller brand?

Rarely at first — hybrid setups require someone to coordinate across vendors, which is itself an administrative cost. They make the most sense once volume and complexity are high enough to justify it.

Should large brands always use an agency?

No. Plenty of large brands run their entire influencer programme on a platform with an internal team, precisely because they want to own the relationships and the data. An agency matters when capacity or specialised expertise is the limiting factor — not automatically past a certain size.
