The essentials
- The simple rule: below €2,000 of monthly media budget, a freelancer or assisted in-house management; between €2,000 and €15,000, a senior freelancer or a small agency; above that, an agency with a creative and data team.
- 2026 costs: freelancer €400 to €800 per day or 10 to 20% of the budget with a minimum of €300 to €600 per month; agency 15 to 20% of the budget with a minimum of €800 to €2,000 per month, creative costs on top.
- The decisive criterion: the ability to produce creative, the first performance lever in 2026, more than campaign settings.
- Non-negotiable: you remain the owner of the ad account, the pixel, the page and the audiences.
Once you have decided to invest in SMA, the next question is whose hand steers: yours, a freelancer's or an agency's. The answer depends on the media budget, the volume of creative to produce, the time available in-house and how mature the account is. This article compares the three options, gives the 2026 costs, the thresholds that tip the choice, the selection criteria and the clauses to insist on. The same question on the Google Ads side is covered in working with a Google Ads freelancer.
The three options compared
| Criterion | In-house | Freelance | Agency |
|---|---|---|---|
| 2026 management cost | Employee time: 1 to 3 days a month for a simple account, plus training | €400 to €800 per day; or 10 to 20% of the media budget, minimum €300 to €600 per month | 15 to 20% of the media budget, minimum €800 to €2,000 per month; creative billed on top (€500 to €3,000 per batch) |
| Skills | Variable; knowledge of the product and the customers | One profile, often specialised (Meta, LinkedIn, e-commerce, B2B) | Several profiles: media, creative, data, strategy |
| Creative production | Limited unless there is an in-house resource | Often limited; some freelancers produce, others subcontract | Studio or network of creators |
| Responsiveness | Immediate | High, depends on their workload | Depends on the size of the account at the agency |
| Continuity | Depends on one person | Depends on one person (holidays, sick leave) | A team, but contacts rotate |
| Suitable media budget | Less than €2,000 per month, or a mature account | €500 to €15,000 per month | More than €5,000 to €10,000 per month |
| Main risk | Lack of perspective and method | Dependence on one person, limited scope | Cost, a junior on the account, standardisation |
The thresholds that tip the choice
- Less than €1,000 per month: external management costs as much as the media; run it in-house with automation (Advantage+), a short training course and a one-off audit by a freelancer (1 to 2 days).
- €1,000 to €5,000: a senior freelancer specialised in your platform and your model (e-commerce or lead generation); the creative often still has to be produced on your side or by a second freelancer.
- €5,000 to €15,000: a senior freelancer with a creative partner, or a small agency specialised in social ads; the volume of creative (10 to 20 a month) becomes the bottleneck.
- More than €15,000: an agency with a creative, data and strategy team, or hiring a traffic manager in-house alongside a studio.
The selection criteria
- Specialisation: B2C e-commerce social advertising and B2B lead generation on LinkedIn are two different jobs; ask for results on your model.
- The creative: who produces the visuals and videos, how many a month, at what cost; a provider who only talks about targeting and bidding is five years behind.
- Measurement: they must set up or check the pixel, the conversions API, consent and UTM before launching; see conversion tracking in SMA.
- Reporting: cost per qualified lead, cost per purchase, ROAS, share of new customers, not just reach and clicks; see the SMA KPIs.
- References: two customers to call, read access to an anonymised account or detailed screenshots.
- The method: test cycle (audiences, creative, offers), frequency of review meetings, alert thresholds.
- Transparency: full access to your account, media invoices paid by you to the platform.
What the contract must cover
- Ownership of the assets: ad account, pixel or dataset, page, catalogue and audiences in your business portfolio; the provider gets revocable partner access; see Meta Business Suite.
- Paying for the media: with your card or your account, never through the provider (except an agency with transparent rebilling).
- Scope: platforms, number of campaigns, creative included, frequency of reports and review meetings.
- Term and exit: a 3-month commitment to absorb the learning phase, one month's notice, handover of access and documentation on exit.
- Objectives: a target cost per result and a volume, reviewed each quarter; no guarantee of results, but thresholds that trigger a review.
- Payment: flat fee or capped percentage; a pure percentage encourages spending.
The warning signs
A provider who wants to create the ad account on their side, who refuses full access, who reports in impressions and clicks, who does not talk about creative or who guarantees a ROAS before seeing your margins should be ruled out. The symptoms of poor management are detailed in the signs of a badly managed SMA campaign ; auditing an existing account in carrying out a social ads audit.
Keeping a hand in-house
Whatever the choice, someone in-house must understand the account: read the cost per result, check measurement, approve the creative and the offers. Two days of training is enough to talk with the provider and spot drift. Metric tracking, independent of the provider, happens in your own dashboard.
How GreenRed helps
Rather than juggling several tools, GreenRed's social media tracking brings these metrics together in a single dashboard, compares them over time and tells you which actions come first. You can try it free, with no card, from the Pricing.
Frequently asked questions
From what budget should you hand your social ads to a provider?
From €1,000 to €2,000 of monthly media budget: below that, the management cost (a minimum of €300 to €600 for a freelancer) weighs too much against the media; run it in-house with automation and a one-off audit. Between €1,000 and €15,000, a senior freelancer is often the best value; above that, an agency with a creative and data team.
How much does running social ads campaigns cost in 2026?
Freelancer: €400 to €800 per day or 10 to 20% of the media budget with a minimum of €300 to €600 per month. Agency: 15 to 20% of the budget with a minimum of €800 to €2,000 per month, creative billed on top (€500 to €3,000 per batch). In-house: 1 to 3 days of work a month for a simple account.
Freelancer or agency: what difference in results?
Campaign settings are comparable; the difference lies in creative production, continuity and scope. A specialised senior freelancer often beats an agency on a mid-sized account; the agency takes the advantage when the volume of creative and platforms exceeds what one person can produce.
What must a contract with a social ads provider cover?
Ownership of all the assets (account, pixel, page, audiences) in your portfolio, the media paid by you, an explicit scope (platforms, campaigns, creative included), reporting on cost per result and ROAS, a 3-month commitment with one month's notice, and handover of access and documentation on exit.
