Should You Hire a Marketing Agency or Do It In-House?

If you’re a business owner, you eventually hit a wall. Sales are flat, the phone isn’t ringing like it used to, or you just have a nagging feeling you could be doing more. You know you need to market your business, but who has the time?

You’ve been doing it yourself—a Facebook post here, an email blast there. Maybe you even boosted a post or two. But it’s inconsistent. It’s one more plate to spin, and it’s always the first one to drop when you get busy actually running your business.

So you arrive at the big question: Is it time to get serious about marketing?

That question leads to another, much harder one: Do I hire someone to work for me, or do I partner with a marketing agency?

We’ve had this conversation over coffee with hundreds of Sioux Falls business owners since we started back in 2002. It’s a classic small business crossroads. This isn’t a sales pitch. It’s a straightforward breakdown of what each path actually looks like, based on what we’ve seen work and what we’ve seen fail.

The In-House Hire: What It Really Looks Like

The first instinct for many owners is to hire someone. It feels like a direct solution. You'll have a dedicated person in your office, focused only on your business. It seems simple enough.

The problem is, it’s rarely that simple. The idea of an in-house marketer and the reality are often miles apart.

The Myth of the "Marketing Unicorn"

Most business owners start by writing a job description for a “Marketing Manager” or “Marketing Coordinator.” They list everything they can think of:

• Manage all social media channels (Facebook, Instagram, LinkedIn, etc.)
• Write and design email newsletters
• Update the website
• Run Google Ads campaigns
• Improve our SEO so we show up on Google
• Write blog posts
• Create videos for social media
• Design brochures and sales materials
• Plan and run events

This person doesn’t exist. Or, if they do, they’re not looking for a job that pays $65,000 a year in South Dakota.

What you’ve just described is not a person; it’s a department. You’re looking for a strategist, a copywriter, a graphic designer, a web developer, a videographer, an SEO specialist, and a paid ads manager all rolled into one.

No single person is an expert in all these areas. Marketing has become far too specialized. The skills that make someone great at writing long-form content are completely different from the skills needed to manage a complex pay-per-click ad budget. The eye for graphic design is not the same as the analytical mind needed for SEO.

When you hire one person to do it all, you’re not getting an expert. You’re getting a generalist. They’ll be pretty good at one or two things (usually whatever they enjoyed most at their last job) and mediocre at the rest. Your marketing will be limited by their personal skill set and their 40 hours a week.

Let's Talk Real Numbers: The True Cost of an In-House Marketer

The sticker shock for many owners isn’t the agency retainer; it’s the fully-loaded cost of an employee they haven't calculated yet.

Let's say you find a decent marketing generalist in the Sioux Falls market. You agree on a salary of $65,000. That’s just the beginning.

Here’s a more realistic look at the annual cost:

• **Base Salary:** $65,000
• **Payroll Taxes (FICA, Unemployment):** ~$5,000
• **Benefits (Health Insurance, 401k Match):** This can be 25-30% of salary. Let's be conservative and say $16,000.
• **Overhead (Desk, Computer, Phone):** ~$2,500
• **Software & Tools:** This is a big one. Professional marketing requires professional tools. A decent subscription for SEO (like Semrush), email marketing (like HubSpot), social media scheduling (like Sprout Social), and design (Adobe Creative Cloud) can easily run $500-$1,000+ per month. Let’s call it $8,000 per year.
• **Training & Conferences:** You want them to stay current, right? That’s another $1,500-$3,000 a year.

**Total Annual Cost:** ~$98,000

Suddenly, your $65k hire is a six-figure investment. And for that $98,000, you get one person’s 40 hours a week and their limited set of skills. You're also on the hook for their ad spend budget on top of this.

We had a client, a local construction company, who went through this exact cycle. They hired a marketing manager for $70,000. After a year, they’d spent over $100,000 when all was said and done, and their website traffic was flat. The person they hired was great at social media but knew nothing about SEO or how to generate actual leads from the website. They were paying a premium for a fraction of the work they needed.

The Hidden Costs: Time, Management, and Turnover

The financial spreadsheet doesn't tell the whole story. The biggest costs of an in-house hire are often the ones you don't see.

First, you have to manage them. This is your time. You’re in charge of setting goals, holding them accountable, reviewing their work, and providing direction. If you’re not a marketing expert yourself, how do you effectively manage someone in a role you don’t fully understand? It becomes a classic case of the blind leading the blind.

Second, what happens when your marketing manager goes on a two-week vacation? Your marketing stops. The blog post doesn't get written. The ads don't get checked. An important lead that comes through the website might sit for days.

Third, and most importantly, is turnover. The average tenure for a marketing specialist is about 1.5 to 2.5 years. When your one marketing person quits, your entire marketing program walks out the door with them. All that institutional knowledge, the passwords, the strategy (if there was one)—it’s gone.

You’re back to square one. You have to write the job description, interview candidates, and train a new person, all while your marketing goes completely dark for months. The cost of this disruption is massive.

Hiring a Marketing Agency: The Other Side of the Coin

Now let's look at the alternative: engaging an agency partner. This can feel like a bigger leap for some owners. You’re entrusting a critical business function to an outside group. But when you look at it from a resource perspective, the logic becomes clear.

You're Not Hiring a Person, You're Hiring a System

When you sign on with a marketing agency, you aren't just hiring a person. You're instantly plugging into a fully-formed marketing department.

Remember that “unicorn” job description? An agency has all those people on staff. For a typical client, their team might look like this:

• **Account Strategist:** Your main point of contact, responsible for the overall strategy and making sure everything aligns with your business goals.
• **SEO Specialist:** Focused solely on improving your organic search rankings.
• **Content Writer:** A professional writer dedicated to creating blogs, web pages, and other content.
• **PPC Manager:** An expert in managing Google Ads and social media ad campaigns to maximize your return.
• **Web Developer:** To handle technical website updates, speed improvements, and security.
• **Graphic Designer:** To create professional visuals for your website, ads, and social media.

Instead of one generalist trying to juggle everything, you have a team of specialists executing in their area of expertise. They collaborate, challenge each other, and bring a breadth of experience from working across dozens of industries. They’ve seen what works for the HVAC company down the street and the retail boutique on Phillips Avenue, and they can apply those lessons to your business.

The Agency Cost Breakdown: What Your Retainer Actually Buys

Agency pricing can seem opaque, but it’s actually pretty simple. Most established agencies work on a monthly retainer. For a small business, this could range from $3,000 to $8,000 per month, depending on the scope of work.

Let’s take a mid-range retainer of $5,000 per month, or $60,000 per year.

How does that $60,000 compare to the $98,000+ for an in-house person?

• You get access to an entire team of specialists, not one generalist.
• All the expensive software and tools are included in the retainer. The agency absorbs that cost.
• You don't pay benefits, payroll taxes, or for a desk and computer.
• There are no sick days or vacation gaps. The team structure means the work always gets done. Someone is always watching your campaigns.
• You get a layer of strategy and accountability that a junior in-house person can't provide.

The value proposition is about leverage. For significantly less than the cost of one fully-loaded employee, you get the output and expertise of a five or six-person team.

The Downsides: Finding the Right Fit and Staying Aligned

This isn't to say hiring a marketing agency is a magic bullet. It comes with its own set of challenges. The biggest one is finding the right partner.

There are bad agencies out there. Some are just sales organizations that outsource the work overseas. Others use a one-size-fits-all template for every client and deliver cookie-cutter results.

An agency is also not an employee. They aren’t sitting in your office, soaking up the company culture every day. This distance means communication is absolutely critical. You, the business owner, have to be willing to invest time in meetings, provide feedback, and share what's happening in your business. A good agency will force this rhythm of communication, but it’s a two-way street.

They also have other clients. You aren't their only focus, and you shouldn't be. A good agency’s strength comes from its diversity of experience. The key is to ensure they have the systems and processes to give your business the strategic attention it deserves without dropping the ball.

When you’re vetting an agency, ask them about their process for communication and reporting. If they can’t give you a clear answer, that's a major red flag.

A Practical Framework for Making Your Decision

So, how do you choose? It’s not about which option is universally “better.” It’s about which model is the right fit for your business, at its current stage, with its current goals.

When Does an In-House Hire Make Sense?

Hiring an in-house marketer can be the right move in a few specific scenarios:

• **You're a larger company (75-100+ employees):** At this scale, you may have the budget ($300k+) to build a true in-house *team*—a marketing director, a writer, a designer, etc. At that point, the economics can start to shift in favor of an in-house department.
• **Your needs are extremely narrow:** If your marketing consists solely of managing an Instagram account and sending one weekly email, you might not need a full agency. A part-time or junior-level coordinator could handle those repetitive tasks.
• **You need a full-time physical presence:** If a huge part of your marketing involves coordinating in-person events, managing a physical showroom, or constant internal communication, having someone on-site every day can be a major advantage.

Even in these cases, many large companies with in-house teams still use agencies for specialized projects like a website redesign or a major SEO push, where they need deep expertise they don't have on staff.

When is Hiring a Marketing Agency the Smart Move?

For the vast majority of small and medium-sized businesses (5-75 employees), hiring a marketing agency is the most logical and financially sound decision.

This path is for you if:

• **You are targeting significant, strategic growth.** You don't just want to 'do marketing'; you want a system that generates a predictable stream of leads and sales.
• **You need a wide range of modern marketing skills.** Your business needs SEO, content, social media, and paid ads working together, and you know one person can't do it all well.
• **You value strategy over task management.** You want a partner who will push back, bring new ideas, and talk about business results, not just how many Facebook posts they made.
• **You cannot afford for your marketing to stop.** You want the consistency and reliability that comes from a team, not the risk that comes with a single employee.

The Hybrid Model: A Powerful Third Option

There's also a middle ground that works incredibly well for many businesses. This is the hybrid model.

In this setup, you hire a junior-level, in-house “Marketing Coordinator.” This person does not set strategy. Instead, they act as the quarterback and liaison between your company and your marketing agency.

Their job is to:

• Attend agency meetings and be the day-to-day point of contact.
• Gather raw materials for the agency: taking quick photos on-site, getting a quote from a technician, passing along a customer story.
• Handle internal marketing tasks like updating sales sheets or coordinating with the sales team.
• Field incoming leads from the agency and make sure they're routed correctly.

This model gives you the best of both worlds. You have someone on the ground who lives and breathes your business, but you also have the high-level strategic horsepower and specialized execution of an agency. The agency focuses on the expert-level work (SEO, strategy, ad campaigns), and the coordinator supports their efforts and keeps the internal gears turning. It’s a highly effective and efficient structure.

The choice between in-house and agency isn't just a line item on a budget. It's a structural decision about how you want to build your business for growth.

Doing it yourself gets you started. Hiring a single person might get you to the next level. But to break through the plateaus that hold most small businesses back, you need access to specialized expertise and a consistent, strategic system.

Whether you build that system with a full internal team over time, or plug into one by hiring a marketing agency, the principle is the same. Stop thinking about hiring a person and start thinking about investing in a capability. That’s how you get off the treadmill and start growing again.
