What an AI automation agency actually does, what it charges, and what you should own at the end

What an AI automation agency does all week, what it charges, the deliverables to demand before you pay, and the red flags I find in other quotes.

Most of what an AI automation agency sells a small business is one job, something a person reads and then types again into another program. The agency puts a language model on the reading and a workflow tool such as n8n or Make on the typing, inside the software you already have. It tests the result on your old cases and reads the logs for a few weeks, and when it leaves, the accounts, the workflows and the API key for the model are in your company's name. Few of the quotes clients forward me say anything about that last part.

On Tuesday, March 11, 2025, an importer from New Jersey called a family wine estate in the hills above Bandol to ask where his pallet was, 600 bottles of rosé that should have left on Saturday's truck to Fos. Since the Friday before, the order emails had not been reaching the invoicing software, because in February the estate had told the agency behind the system that it would stop paying the 1,200 € a month the contract called "optimization." So the agency had switched off its Make account, and all of the estate's scenarios lived inside it.

The export manager called me two days later, and I rebuilt the order flow in six days, on their own accounts this time.

What an AI automation agency does all week

Mostly it asks questions. On my last ten jobs I would say a third of my hours went into understanding how the work is really done, before anything was connected.

At the estate, the export manager told me in the first meeting that all the importer orders arrived by email. I asked her to count the orders for one week on paper. She found 61, and 13 of them were WhatsApp photos of order sheets filled in by hand, sent by two wine shops in Brussels. The previous agency's setup had never received one of them, because she typed those in herself and had forgotten it was a separate job. "I thought the robot did the WhatsApps too," she said.

We picked one process and one number. The number was the time between the importer's email and the order appearing in the invoicing software, 1.8 days on average in the fall and 4 in December, when the Christmas orders come in. The workflow in n8n links the export inbox to the invoicing software, and the model is used only for reading, since a fixed rule cannot read a photo of a handwritten order sheet.

Before it goes live I run a few hundred old cases through it and count the mistakes. For the estate it was the 412 orders from the previous fall, and 9 were wrong, all of them pallets of magnums that the model had counted as 75 cl bottles. Adding one line about bottle formats to the instructions corrected it. After that the export manager approved every order it entered for two weeks, and most of the problems I fix on a project are found during that period.

Strictly speaking, all of this is automation. When the software also decides its own steps and when to ask you, it is an agent; I explained the difference between an AI agent and an automation in another article. Most small businesses need the first kind, and a lot of agencies prefer to sell the second.

Agencies, consultants, and the rest

When you search for AI automation companies, Google puts three different jobs on the same page.

There are the software vendors, who sell you an agent by subscription, and some of these AI agent companies are very good at one narrow thing, usually the phone or bookings. Then there are the consultants. This year I read two proposals, each from an AI automation consultant, one at 750 € a day and the other at 1,100 €. The plans were fine, but neither said who would build the thing.

And there are the agencies, which build it and stay to run it, and that is what most people mean by AI automation services. A lot of the agencies that write to my clients on LinkedIn opened in 2023 or 2024, after plenty of YouTube courses sold the "AI automation agency" as a side business for people with no clients and no code. To find out which ones have learned the job since, ask what they built last year and call that client yourself.

Gartner estimated in June 2025 that out of the thousands of vendors selling agentic AI, only about 130 were real, and it called what the rest do "agent washing": assistants, chatbots and old RPA tools with a new name. In the same release it predicted that over 40% of agentic AI projects will be canceled by the end of 2027, because of escalating costs, unclear business value or inadequate risk controls.

So do you hire someone or not? In the MIT report everybody shared in August 2025, The GenAI Divide, buying from specialized vendors and partners worked about 67% of the time, and internal builds one third as often. The report was based on 150 interviews with leaders, a survey of 350 employees and an analysis of 300 public AI deployments.

Those numbers come from big companies. In a company of five people the internal build is the owner on a Sunday afternoon with a Zapier tutorial, and for simple jobs it works. I wrote about where it stops working in my comparison of n8n, Make and Zapier.

What an agency charges, and for what

The export manager had a fixed quote for the orders only, with no retainer. The estate paid 900 € HT (before VAT), which is where a first automation starts at the studio, and had it in six days. Usually it is one to three weeks. Since then the model and the server have cost the estate around 31 € in September 2025 and 18 € in February 2026, because the monthly part follows the volume of data and the importers order for Christmas in September.

The previous agency had charged 4,800 € HT for the setup, plus the 1,200 € a month. The fourteen quotes my clients have forwarded me since 2024 went from 2,400 € to 22,000 € for the setup. The one at 22,000 € was a website chatbot and two Zapier zaps. Another promised to save 32 hours a week for a company of four, before anybody had looked at its data. Nine of the fourteen had a monthly retainer between 400 and 1,500 €, and two said what it pays for.

In four of them the model and the server were on the agency's accounts and resold, with no margin written anywhere. The estate's quote was one of the four.

Deliverables to demand before you pay the last invoice

Whether it comes from me or from anybody else, here is what you should have in your hands at the end. All the accounts (workflow tool, model provider, server) should be in your company's name, with you as owner and the agency as a user you can remove. The estate now pays for its own n8n server in France and its own key for the model, both on the estate's card.

You should get an export of each workflow with the prompts in plain text, a page that says which job it does and which number it is judged on, and the results of the test on past cases. You should be able to open the logs without calling anybody, and somebody on your side should know how to switch it off.

LangChain surveyed 1,340 people who build agents at the end of 2025: 89% had some kind of observability on their agents and 59.8% used human review. An agency that cannot show you the log of what its automation did last Tuesday is in the other 11%, and its mistakes you will find yourself, usually because a customer tells you.

OWASP puts "excessive agency" at number six in its 2025 Top 10 for LLM applications, and its own example could come from a small business: an assistant that only has to read the emails gets a plugin that can send them too, and a malicious email convinces it to forward sensitive messages to an attacker. The estate's old setup could send emails from the export manager's address, although it only needed to read them.

Red flags

In the quotes people forward me, these are the things that make me pick up the phone:

  • "Fully autonomous" in the first paragraph, and no human approval anywhere in the plan.
  • A website chatbot, sold as an agent.
  • Everything on the agency's accounts, as at the wine estate.
  • A retainer with no number attached to it.

Most agencies with one or two of these are new rather than dishonest. Still, in September 2024 the FTC ran Operation AI Comply against companies selling "AI-powered" income schemes. One of them, Ascend Ecom, had allegedly taken at least $25 million from consumers, and the FTC alleged that another, FBA Machine, cost consumers more than $15.9 million.

The same operation covered DoNotPay, which called itself "the world's first robot lawyer" and agreed to pay $193,000 in a proposed settlement. Lina Khan, the FTC chair at the time, said there is no AI exemption from the laws on the books. A saving guaranteed by a model nobody has tested on your data is not that far from those claims.

How I work

The studio is one person at a bench in La Ciotat, in the south of France, so the person who sells is the person who builds. The export manager can end our arrangement with one email, and nothing breaks; one afternoon I removed my own access to check that this was true.

The five jobs where automation usually pays back inside three months are in my article on where AI automation pays back first.

Ask any agency, me included, what stops on Monday if you stop paying tomorrow. It should be nothing. You can book a fifteen-minute call on the contact page.

FAQ

What does an AI automation agency do?

It automates one job that staff do by hand, usually reading emails or documents and typing them into another program, with a language model for the reading and a tool such as n8n, Make or Zapier for the rest. At the wine estate in this article it was importer orders going into the invoicing software, with the export manager approving each order for the first two weeks.

How much does an AI automation agency charge?

At my studio a first automation starts at 900 € HT (about $1,000), in one to three weeks, plus a monthly cost that follows the volume of data. The fourteen quotes from other agencies I have seen ranged from 2,400 € to 22,000 € for the setup.

Can I set up AI automation myself instead of hiring an agency?

For simple jobs you can, with Zapier, Make or n8n, in an afternoon. With messy emails, or an automation that writes to your customers, it is cheaper to pay somebody than to pay for the mistakes.

What should I own when the agency leaves?

You should own the accounts for the workflow tool, the model provider and the server, an export of each workflow, the prompts, the test results and access to the logs. At the wine estate none of these were in the estate's name, and the order flow stopped as soon as the agency switched off its Make account.
