A lot of owners have asked me some version of the same question this year: will AI replace agencies and consultants? Usually they're asking because they're paying one and quietly wondering what they're paying for.
Here's my honest answer. AI won't replace the people who know what to do. It's already replacing the thing most of those firms actually sold, which is hours.
I built tools and workflows at a 55-person agency before I went out on my own. I like a lot of the people in that world. But the business model is cracking, and owners should understand why before they sign the next retainer.
How the billable-hours model works
Most agencies and consulting firms price the same way underneath. Hours times a rate.
A "retainer" sounds different, but it usually isn't. It's a monthly fee for an assumed block of hours. If the team uses fewer, you rarely get money back. If they use more, you hear about "scope."
Then there are the layers. A typical setup looks like this:
- An account manager who talks to you.
- A project manager who talks to the account manager.
- A specialist who decides what to do.
- A junior who does the clicking and typing.
Every layer bills. Every handoff is a game of telephone. And the actual production, the part that changes your business, sits at the bottom.
That made sense when production was slow and expensive. Building a campaign, a report or a website update took real hours of skilled clicking. Somebody had to do it, and the firm earned its margin on those hours.
What happens when production gets fast
This week I built two Google Ads search campaigns on my own sites with an AI agent driving the browser.
Each one had roughly 100 phrase-match keywords pulled from Google's >Keyword Planner, a negative keyword list, and two responsive search ads with only the first headline pinned so I could test it. I set >ad rotation to rotate indefinitely, $10 a day, St. Louis targeting.
The agent did the clicking. I made every decision and reviewed everything before it went live. It took an afternoon instead of days.
Now picture billing that hourly. The faster I work, the less I make for the same result. The incentive points the wrong way. A firm that bills by the hour either has to pretend the work still takes days, or watch its revenue shrink while the quality stays the same.
That's the trap. AI agents like >Claude in Chrome can now operate real software, so the hours were never going to stay put.
Will AI replace agencies and consultants?
Not all of them, and not the useful part.
What AI replaces is production: the clicking, typing, formatting and setup that filled the bottom of the org chart. It also hollows out the layers that existed mainly to manage that production. If there's less production to coordinate, there's less reason to pay three people to coordinate it.
What AI doesn't replace:
- Knowing what to build. An agent will set up the wrong campaign perfectly.
- Knowing the order. Fixing tracking before buying ads, not after.
- Checking the result. Agents misclick and misread. Somebody has to catch it.
- Owning the outcome. A vendor who stands behind the work.
So the question isn't whether you still need outside help. It's what you should be paying for.
Why layered retainers are in the most trouble
The firms in the worst position are the ones whose margin depends on the layers.
When the junior's eight hours of production become forty minutes of an agent plus a careful review, the account manager and project manager are suddenly managing very little. The firm can cut prices, cut people, or keep billing the old way and hope clients don't ask.
Owners are starting to ask. And small businesses feel this most, because a 3 to 30 person company was always paying for overhead built for much bigger clients.
How to buy outside help now
Whether you're hiring an agency, a consultant or a freelancer, these questions sort out who's selling hours and who's selling direction.
| Question | Hours answer | Direction answer |
|---|---|---|
| What am I paying for? | A block of hours | A defined scope of work, worked in priority order |
| Who does the work? | "Our team" | Named person plus the tools they use |
| Who checks it? | Unclear | The same person, every piece, before it goes live |
| Who owns the accounts? | Sometimes the vendor | Always you |
| Can I leave? | 6 or 12 month term | Month to month |
| How do they use AI? | Vague, or "we don't" | Specific, with human review on anything risky |
A few more tips from my side of the table:
- Ask for a weekly view. You should see what got done every week in plain English, not a monthly PDF.
- Own your logins. Your ad account, your analytics, your website, your CRM. Grant the vendor access. Never let them hold the keys.
- Watch for scope fights. If every small request triggers a change order, the model is hours in disguise.
- Don't pay for layers you never talk to. If you only ever speak to an account manager, ask who actually touches your stuff.
A quick illustration of the math
Say you pay a hypothetical firm for a 20-hour monthly retainer. Half of those hours were always production. If agents shrink that production to a fraction of the time, one of two things is true. Either the firm lowers the price, or you're paying for hours that no longer happen.
I'm not putting dollar figures on that because rates vary too much. Run it with your own invoice. Ask the vendor how many of your hours are now done by AI. The answer tells you a lot.
How I priced my own work
I went flat on purpose. $499 a month, no task cap, month to month. My agents do the production, I direct and review every piece, and we meet once a week. The task list gets worked in priority order, so the price doesn't move when the agents get faster. The details are on my pricing page, and the reasoning behind the model is in why the future of work is directing it.
That's not the only good way to buy help. But I'd look hard at any arrangement where the vendor earns more when the work takes longer.
Frequently asked questions
Will AI replace agencies and consultants?
It replaces the part they mostly billed for: production hours. It does not replace judgment, strategy or accountability. Firms that sell hours of clicking and typing are in trouble. People who sell clear direction and stand behind the result are more useful than ever.
Is a monthly retainer the same as billable hours?
Often, yes. Many retainers are a block of hours with a monthly price on it. Ask how many hours the retainer assumes, who does them, and what happens to unused ones. If the answer is a timesheet, you're buying hours.
What should I ask before hiring an agency or consultant now?
Ask who does the work and who checks it, whether you own every account and file, whether you can leave month to month, how they use AI, and what you'll see each week. Good answers are specific. Vague answers usually mean layers.
Should I just do the work myself with AI?
For small, occasional jobs, maybe. For ongoing work, your time is usually worth more running the business. The tools are getting easier, but knowing what to build, in what order, and whether it came out right still takes experience.
Bring me your current invoice
If you're paying a retainer and can't say what it buys, bring the invoice to a 30-minute call. I'll tell you what I'd keep, what's now cheap to do, and whether I'm the right fit. Or skip ahead and try a $99 first month.
