The short answer: an in-house social media manager costs salary plus benefits, tools, freelancers for video or design, and management time. An agency retainer bundles strategy, creative, posting, ads support and backup coverage under one fee. Neither is automatically cheaper. Pick based on whether you need one dedicated seat or a full stack that already includes filming and paid media. For the manager-side cost breakdown already published, see how much a social media manager costs.
What "in-house" really costs
Budget the loaded salary (not just the posting rate), software, stock or UGC licenses, freelance editors on shoot weeks, and the hours a founder or marketing lead spends directing the work. One strong generalist can own calendar and community. They rarely also shoot cinematic on-location video, run Meta and Google at senior level, and cover vacations without a gap. When volume spikes, quality or response time slips unless you hire more seats.
What an agency retainer usually covers
Pricing models (retainer, per-channel, per-creative, performance) are spelled out in social media agency pricing models when published; until then use the live pricing page above.
Side-by-side decision grid
| Factor | In-house manager | Agency |
|---|---|---|
| Fixed monthly cost shape | Salary + tools + freelancers | Retainer (+ ad spend to platforms) |
| Coverage when someone is out | You scramble or pause | Team backup is the point |
| On-location video | Often vendor extras | Can be included if that is the agency's craft |
| Ads depth | Depends on the hire | Senior buyers if the agency runs paid |
| Brand knowledge | Deep if they stay | Must be onboarded; then shared across the pod |
| Speed to launch | Hiring cycle | Faster if the stack already exists |
When in-house wins
You have steady volume, a clear creative director on staff, and mostly need daily community plus light content. You already buy video and ads elsewhere and only need a coordinator.
When an agency wins
You want social, filming and ads judged on bookings, sales and leads without hiring three roles. You need vacation-proof coverage. You are a practice or South Bay business that wants practitioner-led video without building a studio. See video production Los Angeles and services.
Hybrid options
Some LA companies keep a coordinator in-house and hire an agency for shoots, ads or strategy. That works when roles are written down so nobody assumes the other side owns tracking or replies. Start with a free ad account audit if paid is in the mix (checklist).
Agree the commercial scope
This article does not list fees or platform spend thresholds. Separate media spend from management and production, and agree which work, access and reporting are included before committing.
Plan the next step
For implementation scope, compare specialist marketing services with the full service offering. For a focused Los Angeles plan, see the relevant agency service.
Questions people ask
Is an agency always more expensive than a manager?
Not always. Add benefits, tools, freelancers and manager oversight to the salary before you compare to a retainer.
What does Robbp Media charge for social?
There is no universal amount or guaranteed result. Agree a scope and measurement plan using your own business data before starting.
Can we start with an agency and hire later?
Yes. Many teams use an agency to build the system, then bring coordination in-house once the playbook is proven.
Do you replace our internal marketer?
We can partner with them. The goal is more booked outcomes, not office politics.
Where should we start this week?
List every task you expect social to own, price those tasks both ways, and audit tracking before you scale spend.
Who approves the plan before launch?
Agree the scope, factual claims, review responsibilities and reporting definitions before anything is published.
