Most brands can run influencer marketing in-house, and around two-thirds do. The decision between in-house and agency comes down to three variables: how much team time you can commit, how much campaign volume you run, and what a mistake costs you. In-house wins on control and cost per campaign at volume; an agency wins on speed, existing creator relationships, and avoided errors.
The short answer: run it in-house when influencer marketing is a constant, core channel and the volume justifies dedicated headcount. Use an agency when you need to move fast, want vetted relationships instead of cold outreach, or cannot afford to learn vetting, disclosure, and rights negotiation on live budget. Many brands sensibly do both.
Key Takeaways
- Around two-thirds of brands run influencer programs internally, so in-house is normal, not a compromise.
- An agency’s fee buys sourcing, vetting, briefing, contracts, payments, rights, coordination, and reporting, plus the mistakes you never make.
- In-house is cheapest per campaign once volume is steady; the hidden cost is the time to build vetting and rights expertise.
- The most common end-state is hybrid: routine campaigns in-house, an agency for scale, new markets, or specialist briefs.
- Whoever runs it, the brand carries the legal responsibility for disclosure and claims, so process quality is not optional.
What Does an Influencer Marketing Agency Actually Do?
An agency runs creator campaigns end to end: strategy, finding and vetting creators, briefing, negotiating and contracting, coordinating content and timelines, handling payments and usage rights, and reporting results against the goal. The value is concentrated in two places: time saved (sourcing and coordination are hours-heavy) and mistakes avoided (fake audiences, missed disclosure, rights that were never secured).
On money: agencies charge a management fee on top of creator costs, a bundled project rate, or a retainer for ongoing programs, with creator fees, product, and paid amplification billed separately. Ask any agency for the split between their fee and what reaches creators; a good one shows it without being asked. Fee context sits in our influencer marketing cost guide and on our pricing page.
Can You Run Influencer Marketing In-House?
Yes, and most brands do: roughly two-thirds of companies run their influencer programs internally (Influencer Marketing Hub). The channel has no gatekeeper; what it has is workload.
Running it in-house means owning every step of the campaign process: goal-setting, budgeting, sourcing and vetting, outreach and negotiation, briefs, contracts, logistics, disclosure compliance, and measurement. The two steps that punish inexperience are vetting (fake and mismatched audiences are invisible until the results arrive, which is why the vetting checklist exists) and rights (content you cannot legally reuse is value left on the table).
There is also a liability point worth being clear-eyed about: under Australian Consumer Law, the brand is responsible for claims in posts it incentivises (ACCC). Whoever runs the campaign, the compliance risk stays yours, so the process has to be sound either way.
When Does Each Option Win?
| Your situation | Better fit |
|---|---|
| First campaign, no creator experience in the team | Agency, or a hybrid with agency sourcing |
| Occasional campaigns around launches and events | Agency per campaign, no retainer |
| Constant always-on program with steady volume | In-house, agency for peaks |
| Entering a new market or niche you do not know | Agency with an existing network there |
| A specialist brief (events, tours, multi-city) | Agency with that track record |
| Strong in-house social team with spare capacity | In-house, platform tools for discovery |
Hire an agency when you want speed without adding headcount, when existing creator relationships matter, or when the brief is outside your team’s experience. Build in-house when influencer marketing is core, continuous, and high-volume enough to justify a dedicated salary, because at that point the agency fee buys work your team could absorb.
The Hybrid Model Most Brands Land On
The agency-versus-in-house framing suggests a permanent choice, but in practice most brands converge on a mix. The common path: start with an agency to learn what works (which tiers, formats, and creators move your numbers), then bring the routine parts in-house (ongoing creator relationships, repeat briefs, community management) while keeping an agency for scale moments, new verticals, and campaigns where specialist coordination earns its fee.
The inverse hybrid also works: in-house owns strategy and measurement, and an agency handles sourcing and vetting only, the most time-expensive step. Per-campaign pricing with no retainer, which is how we work, exists precisely so brands can use an agency at the moments it pays and not in between.
How Do You Choose a Good Agency?
If the decision lands on agency, choose on process, not promises.
- Relevant experience. Campaigns in your industry or an adjacent one, with results they can describe specifically.
- A real network, not a database. Existing creator relationships mean faster launches and honest intel on who delivers. Ask how many of their creators they have actually worked with.
- A visible vetting process. They should explain exactly how they check audience location, engagement authenticity, and disclosure history.
- Transparent money. A clear split between the agency fee and creator costs, and a straight answer on how usage rights are priced.
- Reporting tied to outcomes. Ask what a results report looks like; it should lead with spend against return, not a collage of likes.
- Compliance fluency. They should raise AANA disclosure and ACCC obligations before you do.
The red flags are the mirror image: guaranteed virality, reach sold without fit, vague fees, and creator lists they have never worked with.
Does This Apply to B2B Brands Too?
Yes, with different creators and platforms. Consumer brands dominate the channel, but B2B brands increasingly partner with industry experts and niche creators on LinkedIn and YouTube to reach decision-makers, and the logic is identical: a trusted voice in the category outperforms an ad. The agency-versus-in-house calculus is the same; only the talent pool changes.
Frequently Asked Questions
How do influencer marketing agencies charge?
A management fee on creator costs, a bundled project rate, or a retainer for always-on programs. Creator fees, product, and ad spend are separate lines. Always ask for the breakdown so you can see what runs the campaign versus what reaches creators.
Do agencies handle contracts and content licensing?
Good ones do. We handle contracts and licensing as part of every campaign, so the brand has clearance to run Spark Ads, boost creator posts, and reuse content across its own channels without renegotiating after the fact.
What kinds of businesses get the best results?
Businesses with a clear audience, a product or experience people can show, and a defined goal: hospitality, food and drink, beauty, retail, tourism, and events consistently perform. With the right creators and a realistic goal, almost any business can make the channel work; the evidence is in does influencer marketing work in Australia.
How fast can an agency launch compared with in-house?
With relationships already in place, a standard agency-run campaign goes from kickoff to live content in 3 to 6 weeks, and urgent activations can compress to about two. An in-house first campaign usually runs longer, because sourcing, vetting, and contracting are being built from scratch.
Decide on Workload, Not Ideology
Neither option is the “professional” one; the professional choice is matching the model to your volume, timeline, and appetite for learning curves. If you want the agency side of the comparison priced for exactly that decision, per campaign, no retainer, no lock-in, our services page shows what end-to-end management covers, and the influencer marketing FAQ answers the rest.
