A marketing agency typically costs $1,500 to $10,000 per month for ongoing management, and ad spend is paid on top, straight to Google, Meta or LinkedIn. One-time projects like a website or a brand are quoted separately. For a local service business, the real test is simple: the agency should return more booked work than it costs.
If you are shopping for an agency, you have probably been quoted numbers that are hard to compare. One firm wants a monthly retainer. Another wants a cut of your ad spend. A third offers to work for a fee per lead. Each model pays the agency for something different, and that shapes what they work on. The simplest way to compare them is to ask what each one costs you per booked job. It is the same approach behind our integrated marketing services.
How Marketing Agencies Charge: 5 Pricing Models
Almost every agency uses one of 5 pricing models, or a mix. Here is how each one works:
- Monthly retainer: you pay a flat fee each month for ongoing management, typically $1,500 to $10,000, and ad spend is paid on top, directly to the platforms.
- Project fee: you pay a fixed price for a defined piece of work with an end date, such as a website, a brand identity or a launch.
- Hourly: you pay for time as it is used, which suits advice and small fixes but makes monthly costs hard to predict.
- Percentage of ad spend: the agency takes a share of whatever you spend on ads, so its fee rises as your budget rises.
- Performance-based: the agency is paid per lead, per sale or as a share of revenue, often with a low base fee or none at all.
The retainer is the most common model for ongoing marketing. It pays for a team's time and attention, and it lets you judge the result on its own terms. Project fees make sense for work with a clear finish line. Hourly works for a few hours of advice, not for running your marketing.
The last two sound fair, but they pay the agency for the wrong thing. A percentage of ad spend rewards spending more, not spending better. An agency that finds and cuts wasted spend also cuts its own fee. Performance deals reward whatever gets counted. If you pay per lead, you get more leads, including the ones that never turn into a job. The agency also prices in its risk, so the good months often cost you more than a retainer would have. We go deeper on this in our post on a marketing budget for small businesses.
What Drives the Cost of a Marketing Agency
Two businesses can get quotes that are thousands of dollars apart for what sounds like the same service. The difference almost always comes down to 4 things:
- Scope: how much of your marketing the agency owns, from one channel to the whole system.
- Channels: each one you add, such as Google Ads, Meta, SEO or social media, needs its own setup, management and reporting.
- Production: video shoots, photography, new web pages and written content take real hours every month.
- Senior time: how often an experienced strategist, not a junior coordinator, looks at your numbers and makes decisions.
Your industry changes the mix. A moving company lives on urgent searches, so most of the budget goes to Google Ads, the Map Pack and fast follow-up. A law firm pays for some of the most expensive clicks in local search, and its buyers often compare firms for days or weeks. More of its retainer goes into content, reviews and intake tracking, so each case can be traced to its source. The same problem looks different by vertical, as our page on law firm marketing shows.
The cheapest quote is often the one with the narrowest scope. That is fine if you only need one channel. It gets expensive when you hire 3 vendors for 3 channels and nobody connects their results to booked work. This ties directly into integrated marketing strategy, which we cover in a separate post.
What ABMG Charges: $3,500 to $6,500 per Month Plus Ad Spend
Our engagement tiers are published: $3,500 to $6,500 per month, plus ad spend. The ad budget is paid to Google, Meta or LinkedIn through accounts you own, so you can see every dollar the platforms charge.
Every tier is run by one team that covers paid ads, SEO, content, social media, web and CRM, so the channels you use are planned together. You do not manage separate vendors or referee between them. What changes as you move up is how many channels run at once, how much gets produced each month and how much senior strategy time goes into your account. At the entry level, the focus is the few channels most likely to book work first, with tracking in place. The higher levels add channels, more content and video production, and more senior planning time.
One rule holds at every level: you own every account, file and asset. Your ad accounts, analytics, website, CRM and content stay in your name. If we ever part ways, nothing has to be handed back, because it was always yours.

What a Marketing Agency Retainer Should Include
Whatever you pay, a retainer is a promise of attention and accountability. At a minimum, it should include:
- A named lead who knows your business and answers for the results, not a shared inbox.
- A monthly report that shows leads and booked work by source, such as Google Ads, organic search, Meta or referrals.
- Admin access for you to every account, including ads, analytics, your website and your CRM.
- A written plan for the next 30 to 90 days, so you can see what the fee is buying before the month starts.
If a retainer includes all of that, you can judge it. If it does not, you are paying for activity you cannot see.
Questions to Ask and Red Flags Before You Hire an Agency
These questions tell you most of what you need to know:
- Who will run my account day to day, and how often will I hear from them?
- Will the ad accounts, analytics and website be in my name from day 1?
- How do you track a lead from the first click to a booked job?
- What does the contract require if I want to leave?
Then watch for these red flags:
- You do not have access to your own ad accounts, analytics or website.
- The contract locks you in for a long term with no way out if results never show up.
- Reports lead with impressions, reach and clicks instead of leads and booked work.
- Ad spend is billed through the agency, and you cannot see what the platforms actually charged.
How to Tell If Your Marketing Agency Is Paying for Itself
The cleanest test is cost per booked job by source, measured over 90 days. Add up what you spent on each channel, including its share of the agency fee, and divide by the jobs that channel booked. Compare that to what a job is worth to you. Use 90 days, not 30. Paid ads settle in faster, but SEO and content take longer to show up in booked work, and a single month is too noisy to judge.
Here is what that looks like when it works. Just Better Moving, a Parsippany mover, earned a 2.60x return on ad spend and 27 booked moves over 16 weeks. Over the same 16 weeks, organic search booked 23 more moves worth $17,204. Both results are tracked by source, from the first visit to the booked move. That is what a retainer should produce. For proof, look at 2.60x ROAS and $17,204 booked from organic search.
If an agency cannot show you numbers like that after 90 days, the price was never the real problem. The reporting was. Pick a model that pays for attention, insist on owning your accounts and judge every dollar by the work it books. We have seen this play out firsthand, as our post on small business marketing in New Jersey explains.

Frequently Asked Questions
How much should a small business pay a marketing agency?
Most service businesses spend 5 to 10 percent of revenue on marketing in total, and that covers both the agency fee and the ad budget. Agency management typically runs $1,500 to $10,000 per month. Start with the channels most likely to book work quickly, prove the cost per booked job over 90 days, then add channels once the first ones pay back.
Is ad spend included in a marketing agency's fee?
Usually not. Most agencies charge a management fee, and ad spend is paid on top, directly to Google, Meta or LinkedIn. Ask whether the ad accounts are in your name and whether you can see what the platforms charge. At ABMG, our $3,500 to $6,500 monthly tiers are plus ad spend, paid through accounts you own.
Are performance-based marketing agencies worth it?
They can look safe, but the incentives often work against you. An agency paid per lead is rewarded for volume, not for leads that turn into booked jobs. Most also price in their risk, so strong months can cost more than a flat retainer would. A retainer with clear reporting by source and booked work is usually easier to judge and easier to trust.
