Agency or in-house marketing hire? How to decide

Start with what you are really buying

You are buying some mix of three things: skills (people who can do the work well), capacity (hours to get it done) and ownership (someone accountable who knows your business). Agencies sell skills and capacity. A hire gives you ownership and some capacity, but rarely all the skills.

When an agency tends to fit

• You need several specialist skills for a defined job, such as a website rebuild, a paid-search launch or a content programme.
• You need to start soon and cannot wait months to recruit.
• The work is project-shaped or may change a lot, so a permanent salary would be hard to justify.
• You have someone internal who can brief the agency and judge its work.

When an in-house hire tends to fit

• Marketing is central to how you grow and will stay that way for years.
• Deep knowledge of your customers and product matters more than breadth of skills.
• You can write a clear job description with three to five outcomes the person will own.
• You have, or will have, someone who can manage and mentor them with real marketing judgement.

When a mix works

Many small companies end up with one in-house owner plus specialist help: a marketing manager who sets direction and measures results, with an agency or freelancers for work needing deeper skills. It costs more to coordinate but avoids both the single-point-of-failure hire and the agency that nobody inside is steering.

The costs people forget

• Agency: your management time, onboarding, approvals, and the fact that ad spend is usually separate from fees.
• Hire: salary, benefits, tools, recruiting time, a ramp-up of several months, and the risk that one person leaves with everything they know.
• Both: a slow first quarter. Neither delivers meaningful results in the first month.

A simple decision path

1. Write down the three outcomes you want in the next 12 months, in numbers where you can.
2. List the skills those outcomes need. If it is more than two or three different skills, one hire will not cover it.
3. Ask who will manage the work every week. If the honest answer is nobody, fix that before choosing either path.
4. Check you can fund the choice for at least six months without panicking.
5. If you still cannot decide, start with the smallest reversible step: a short, tightly scoped agency project or a part-time specialist.
