Declaring the bias upfront
We are an agency. We benefit if you choose an agency. Read accordingly. That said, we have told prospects to hire in-house often enough to be reasonably honest about when it is right, and the answer depends far more on your stage than on any general argument.
The comparison people get wrong
The usual mistake is comparing an agency retainer to one salary. The real comparison is to a full team, because marketing is not one skill.
To cover what a mid-sized agency retainer covers, you need paid media, SEO, content, design, some development, and analytics. In-house that is several salaries plus tooling. Hiring one generalist to do all of it produces someone competent at one thing and out of their depth in four.
Do not forget the costs that never appear in the comparison: recruitment, notice periods, the two to three months before a new hire is productive, tool subscriptions, training, and the risk that your single specialist leaves and takes the institutional knowledge with them.
Hire in-house when
- ✓One channel dominates and needs daily attention. A large, single-platform ad account genuinely benefits from a dedicated owner.
- ✓Deep product knowledge is the bottleneck. Complex technical or regulated products where explaining the product is the hard part.
- ✓You are big enough to hire a real team, not one person doing six jobs.
- ✓Speed of internal coordination matters more than breadth of skill.
Use an agency when
- ✓You need several skills part-time. Most businesses need a fraction of a designer, a fraction of a developer and a fraction of a media buyer.
- ✓You are not sure what works yet. Agencies see patterns across many accounts. That pattern recognition is genuinely hard to build from one dataset.
- ✓You need to start now. Hiring takes months. Onboarding an agency takes weeks.
- ✓The workload is lumpy. Campaign peaks, launches, exhibition seasons.
The arrangement that usually wins
For most mid-sized businesses the best structure is neither. It is one strong in-house marketing manager who owns strategy, brand knowledge and internal coordination, plus an agency for execution depth across channels.
That person is the difference between an agency that performs and one that drifts. They hold context, make decisions quickly, and push back credibly. Agencies without an engaged client counterpart tend to produce activity rather than outcomes, and any agency claiming otherwise is selling you something.
Questions that settle it
- 1How many distinct skills does your plan need in the next twelve months?
- 2Can you attract and retain specialists in your location and budget?
- 3Is your workload steady or lumpy?
- 4Does anyone internally have the time to actually manage an agency?
If you would like a straight answer about which side of this line you are on, we will give you one on a call, including when it is "hire someone, not us". Our services are on the performance marketing, web development and SEO, AEO and GEO pages.
Frequently asked questions
Is an agency cheaper than hiring in-house?
For breadth of skill, usually yes, because you are buying fractions of several specialists rather than whole salaries. For a single channel at high volume, a dedicated in-house owner often wins on cost.
What is a reasonable agency retainer?
It varies enormously by scope and seniority. What matters more than the number is whether the scope is written down clearly and whether you can tell what you are getting each month.
How do I stop an agency relationship drifting?
Have one internal owner, agree three metrics that define success, and hold a monthly review against them. Drift almost always starts when nobody internally has time to engage.
