Full Service Marketing Agency: What It Does and What It Costs

A full service marketing agency runs most or all of your marketing for you, and its fees often run $5,000 to $50,000 a month, before you pay a cent for ads. That range comes from Clutch's digital marketing pricing data. What you get for the money changes a lot from agency to agency, because "full service" has no fixed meaning. This guide covers what these agencies do, how they bill, what to check in the contract, and when a marketing subscription or your own team makes more sense.

One note first. We sell a marketing subscription, so we are not neutral here. We will say plainly where a full-service agency is the better buy, and what we do not do. We checked every source below on 18 October 2026.

The short answer

• What it does: strategy, ads, website, SEO, email, content and design. Bigger agencies add PR, video, TV and print.
• What it costs: often $5,000 to $50,000 a month in fees. Ad spend is extra.
• How it bills: a monthly retainer, a project fee, by the hour, or a cut of your ad spend.
• Best for: big media budgets, TV, PR, filming, and many teams working at once.
• Simpler option: a flat-fee subscription, if your work is mostly digital and can go one job at a time.

What is a full service marketing agency?

It is one outside team that handles most of your marketing. You do not hire an SEO firm, an ads firm and a web designer and then try to get them to talk to each other. One agency owns the plan and does the work.

There is no rule for what counts as full service. Each agency writes its own list. We read three agency homepages that rank on page one of Google for "full service marketing agency". One listed public relations and video production. Another listed connected TV, out-of-home ads, podcasts and print. A third listed SEO, ads, video and photography, and Amazon marketing. All three call themselves full service.

"Full service" means whatever the agency says it means. Get the list in writing.

What is a full service digital marketing agency?

A full service digital marketing agency does only the online side. That usually means ads on Google and Meta, SEO, your website, email and social media. It does not make TV ads, radio spots or print. In our view, this is what most small and mid-sized businesses mean when they search for a full service marketing company.

Full service agency vs specialist agency

A specialist does one thing, like only SEO or only Google Ads, and a good one can go deeper in it. The cost is that you become the person joining the pieces. If your ads agency and your web designer do not talk, you hear about it when the leads stop. A full-service agency takes that job off you, if it does it well.

What does a full service marketing agency do?

Here is the work most full-service lists include, with a column for what Havstock Unlimited covers. We put that column in so you can see where we stop.

The Havstock column is from our own offer, checked 18 October 2026. If you need an app or a custom tool, ask any agency if that is in the fee. If the "No" rows are a big part of your plan, a full-service agency is likely the better fit. More on that below.

How much does a full service marketing agency cost?

Most agencies do not publish prices. None of the agency homepages we read on page one listed one. So the best numbers come from pricing data across many agencies.

Sources: Clutch's digital marketing pricing guide and its advertising agency pricing guide, both updated 21 September 2026. MarketerHire's "Marketing Agency Pricing: What to Expect in 2026", dated 17 June 2026. All checked 18 October 2026. MarketerHire places freelance marketers, so it has a side too.

Clutch also says the typical advertising project in its reviews runs "around 20 months". So the contract matters as much as the monthly price.

Is ad spend included in the agency fee?

No. The fee pays for the agency's work. Ad money goes to Google, Meta and the rest on top. Clutch's advertising guide says agency fees "are not included in the cost to run advertising campaigns." So a $10,000 a month agency running $10,000 of ads costs you $20,000 a month. Our guide to what Instagram ads cost shows how the ad side of the bill works.

The agency fee and the ad budget are two different bills. Ask for both numbers before you compare quotes.

How do full service agencies bill?

There are a handful of common ways. Some agencies mix two, like a retainer plus a cut of ad spend.

Clutch's media buying pricing guide (updated 21 September 2026, checked 18 October 2026) lists commission, hourly, project and performance-based fees. It says the commission is often 10% to 20% of total media spend. Clutch's advertising guide adds that it is "common" to keep an agency on a monthly recurring basis.

Few big advertisers still pay agencies by commission. In the Association of National Advertisers' 2022 study, only 7% of marketers used commissions for their agency services overall. For media planning and buying, it was 19%. That is as reported by MediaPost on 14 December 2022.

What does a percent of ad spend fee look like?

Here is the maths with example numbers, not results. Say you spend $20,000 a month on ads and the agency takes 15%. That is $3,000 a month in fees. Double the spend to $40,000 and the fee doubles to $6,000. The ads may need little extra work. You pay more anyway.

Hourly is similar. At Clutch's US rate of $100 to $149 an hour, 40 hours a month costs $4,000 to $5,960. Same idea: example numbers.

What to check in an agency contract

The monthly price is the part you see. These are the parts that cost you later.

• Minimum term. MarketerHire's guide says "Most agencies push 6-12 month contracts" and some ask for 3 months. Not all do. One big agency on page one says on its homepage that it does not require long-term contracts.
• Notice period. The same guide says some agencies ask for 90 days' notice. That is three more months of fees after you decide to leave.
• Auto-renewal. Check if the contract renews on its own, and how many days before the end you must cancel.
• Setup fee. Ask if there is one, and what it pays for.
• Who owns what. Your ad accounts, website, domain, CRM, ad designs and data should be yours.

Google has rules that help with that last one. Its transparency requirements for third parties (checked 18 October 2026) say an agency must give you your Google Ads customer ID when you ask. Where the agency must send monthly reports, those reports must show costs, clicks and impressions. Any management fee must be told to you in writing before your first purchase and shown on every invoice.

Ask who owns the ad accounts before you sign. Leaving is much harder when the agency owns them.

Full service agency vs marketing subscription vs in-house team

Here is how the three main ways to get a team compare.

The in-house number uses median US pay from the Bureau of Labor Statistics for May 2025: $78,760 for a marketing specialist, $92,650 for a web developer and $62,960 for a graphic designer. That is $234,370 a year, or about $19,531 a month. In June 2026, wages were 70% of what US private employers spent on staff, and benefits were the other 30%. We did the full maths on hiring in our guide to agency retainers vs a subscription vs in-house.

Havstock Unlimited is our version of the subscription. It is $4,995 USD a month, month to month. It covers a strategy call, ads on Meta, Google and LinkedIn, websites and funnels, apps and custom software, email, your CRM, SEO and AEO, AI chat on your site and a monthly results report. Most requests are done in about 48 hours. You get a small team with no juniors and no outsourcing. Try it for a week, and if you are not happy, you get 75% back.

To be fair about price: $4,995 is just under the bottom of Clutch's range, but it is not the cheapest way to get marketing. A small local agency or a freelancer on one channel can cost less. If you only need one thing, like monthly SEO, a specialist may be the better deal.

When a full service agency is the better choice

Some plans need things we do not do. Here is when we would tell you to hire a full-service agency.

• You need TV, radio, billboards or print. We do not make or buy any of these.
• You need PR. We do not do press coverage or media interviews.
• You need filming or photo shoots. We do not film, shoot photos or edit video.
• You want daily posts on your social accounts. We do not do organic social posting.
• Your media budget is very large. Our view: once you spend heavily across many channels, a big agency's media team and reporting can be worth the fee.
• You need many teams at once. A launch with ten jobs due in the same week needs people working side by side. We work one request at a time.

If your plan needs a film crew, a press release and a TV slot, hire a full-service agency. We are the wrong fit.

When a marketing subscription fits better

• Your marketing is mostly digital: ads, pages, email, SEO and your CRM.
• You have a steady stream of jobs, not one giant launch.
• You do not want a long contract or a notice period.

When an in-house team fits better

Hire your own people when you have enough work to keep several of them busy all year, or you need someone in the building. If what you really lack is a leader to own the plan, not more hands, read our guide to a fractional CMO vs an agency vs a subscription.

Is a full service marketing agency worth it for a small business?

It can be, if you will use most of what you pay for. Some full-service agencies are built around PR, video and big media buys. If you will never need those, you may be paying for a team you do not use.

Do this check before you sign. Example numbers, not results:

1. Take the monthly fee. Say $8,000.
2. Add your monthly ad spend. Say $5,000. That is $13,000 a month.
3. Take the profit on one average sale. Say $1,000.
4. Divide: $13,000 divided by $1,000 is 13 sales a month just to break even.

If 13 extra sales a month is easy for your business, the agency has room to pay off. If you sell 5 jobs in a good month, it is a big bet. Do the same maths for any option, us included.

Questions to ask before you sign

1. What exactly is in the fee? Get the list in writing, plus what costs extra.
2. Who will do the work? Ask for names and roles. Ask if any work goes to another company.
3. How do you bill? Retainer, hours, project, or a share of ad spend.
4. Do I pay the ad platforms directly? Paying them yourself keeps the ad spend clear.
5. What is the minimum term and notice period? And does the contract renew on its own?
6. Is there a setup fee? What does it cover?
7. Who owns the accounts and files? Ask for admin access to your ad accounts, website and CRM from day one.
8. What will the monthly report show? Ask for cost per lead and sales, not just clicks.
9. How long does a normal request take? Ask for a real example.
10. What happens when we leave? Ask how they hand over the accounts, pages and data.

A good agency will answer all of these without fuss. If an agency dodges the ownership question, walk away.

FAQ

What does a full service marketing agency do?

It handles most of your marketing in one place. That usually means strategy, paid ads, your website, SEO, email, content and design. Bigger agencies add public relations, video production, TV, radio and print. There is no fixed list, so each agency decides what full service means. Ask for the list in writing before you sign.

How much does a full service marketing agency cost?

Clutch's pricing data puts digital marketing agencies at $5,000 to $50,000 a month, and US agencies at $100 to $149 an hour. Its reviews of advertising projects average $9,890.93 a month. Those are fees only. Your ad spend goes to Google, Meta and other platforms on top of that.

What is the difference between a full service agency and a specialized agency?

A specialist does one thing, like SEO or Google Ads, and can go deep in it. A full-service agency covers many channels and joins them up for you. With specialists, you manage the handoffs between firms yourself. With one full-service agency, it does that part, though you pay for the extra services too.

What percentage of ad spend do marketing agencies charge?

Clutch's media buying guide says commissions often run 10% to 20% of total media spend. Plenty of agencies charge a flat fee instead. In the ANA's 2022 study, only 7% of marketers used commissions for agency services overall, and 19% for media planning or buying. Ask which model you are on.

Do full service marketing agencies require long contracts?

Many do. MarketerHire's 2026 pricing guide says most agencies push 6 to 12 month contracts, and some want 90 days' notice to leave. Not all agencies work that way, so read the minimum term, notice period and auto-renewal terms before you sign. Month to month options exist.

Is a full service marketing company the same as a full service agency?

Yes. People use both names for the same thing: one outside firm that runs most of your marketing. Some say "company" or "firm" and some say "agency". What matters is the list of services, how they bill and what the contract says.

Is a marketing subscription cheaper than a full service agency?

Often, but not always. Havstock Unlimited is $4,995 USD a month, flat, which is just under the bottom of Clutch's agency range. A small agency doing one channel can cost less. Havstock also works one request at a time and leaves out filming, PR and print. Compare what you get as well as the price.

A full service marketing agency is worth the money when you will use most of what it does: PR, filming, TV, big media buys and many people working at once. If your marketing is mostly digital and steady, you may get what you need for less with a subscription or a smaller team. Either way, ask for the full list, the fee model and the contract terms before you sign with any full service marketing agency.
