DIY Social Media With AI or Hand It Off? The Real Cost for Medium-Sized Businesses
Once a business gets to 50 or 100 staff, social media usually lands in 1 of 3 places: an overstretched marketing person, a new hire, or "we'll just use ChatGPT". Each has a price, and most businesses only count the obvious one.
This post runs the real numbers so you can decide with your eyes open.
What does a social media manager cost?
Market | Average base salary | Typical range | Source |
UK | £29,313 | £21,000 to £45,000 | |
US | $60,881 | $41,000 to $88,000 |
For North America and Europe, check local salary data for your city, as ranges vary a lot by market.
That's base salary only. On top you'll pay employer taxes and pension or benefits, plus:
Scheduling, design, video editing and AI tool subscriptions
Training to keep up with platform changes
Holiday and sick cover, when posting often stops
Your own time managing, briefing and approving
Recruitment costs, and starting again if they leave
The job is bigger than 1 person
The average social media user is on 6.75 platforms a month (DataReportal). HubSpot's 2026 State of Marketing report shows brands spread across Instagram (70%), Facebook (69.6%), X (55.8%) and TikTok (54.5%), with short-form video the top format for ROI.
So a single hire is expected to be a strategist, copywriter, video editor, designer, community manager and data analyst. That's before anyone mentions brand activation.
The pressure is going up, too. 83.5% of marketers in HubSpot's research were expected to produce more content in the past year, and 35.7% were asked for much more. 29.8% named keeping up with trends and platforms as a top challenge, and 33% said measuring ROI was their biggest one.
Can AI plug the gap?
Partly. AI saves hours on drafting and reporting, and we cover how in How to use ChatGPT for social media. It won't fill the strategy, video or community gaps, and obvious AI content has a trust cost: 52% of consumers disengage when they suspect it (Bynder).
Then there's replies. Sprout Social found 71% of social users will buy from a competitor if a brand doesn't answer customer service questions. A tool can't sit in your DMs and care.
Your 4 options compared
Option | Who does the work | Best for | Watch out for |
DIY with AI | Existing staff plus ChatGPT | Very tight budgets, low posting needs | Generic content, burnout, gaps when staff are busy |
In-house hire | 1 employee | Businesses needing someone on site daily | 1 person covering 6 roles, cover gaps, churn |
Train your team | Your staff, properly skilled | Teams with time but no know-how | Needs someone to own it week to week |
Done for you | A specialist agency like ours | Businesses wanting results without adding headcount | Pick an agency that knows your industry and your voice |
When to hand it off
Hand social media to an agency if:
Posting stops every time your team gets busy
You have launches, openings or campaigns coming and no one to run them properly
Your leadership team can't see what social is delivering
You're paying for tools nobody has time to use
Keep it in-house and train your team if you have someone with the time and appetite to own it, and you mainly need the skills and a system.
