AI agents for small business: notes from seven jobs, with the numbers and what broke

AI agents for small business, from my job notebook: seven agents I set up near Marseille, what each cost, the number before and after, and what broke.

Owners ask me whether AI agents for small business are worth paying for, and in my notebook they were when they took on calls, replies or follow-ups that nobody on the payroll got to on time, which I could count in missed calls, hours of delay and quotes that went out. If none of those is a problem, I'd keep the money.

The notebook is a graph-paper one from the stationery store behind the port in La Ciotat, and the entries below, on seven businesses around Marseille in the south of France, are copied from it with their dates. My studio charges €900 before tax to set up a first agent, around $1,000, for one to three weeks of work, and the client then pays the model's bill every month, which goes up and down with the volume of data the agent processes.

What an agent is, and why the chat bubble on a website isn't one, is in a separate piece for business owners.

Seven AI agents for small business, from the notebook

June 15, 2025. Cassis, real estate agency

The agency has two real estate agents and gets about 180 requests for showings a month in summer from three listing sites (SeLoger, Leboncoin and Bien'ici, the French Zillows), and until this spring somebody read them twice a day, at 9 in the morning and at 6, by which time, as the owner said at our first meeting, "they've booked a showing with somebody else."

Since April the agent answers each request in under three minutes, asks about the budget, the moving date and whether a mortgage is actually in progress, and files the contact in the CRM with a score out of 5, with times offered only to the 4s and 5s. The first reply has gone from 11 hours on average to 3 minutes.

A couple toured three houses on a 5 they got for writing "financing all set," and they had never spoken to a bank, so from tonight the agent asks which bank.

The figures I keep in mind here come from a 2011 HBR study, in which a test inquiry sent to 2,241 US companies got its reply after 42 hours on average, and firms that answered within an hour were nearly seven times as likely to qualify the lead as those that waited even an hour longer.

Added in January 2026: showings as a share of requests went from 22% in the first half of 2025 to 31% in the second half, for around €40 a month.

June 25, 2025

A Gartner forecast made the rounds today: more than 40% of agentic AI projects will be canceled by the end of 2027, as costs climb and the business value stays unclear. I copied the sentence onto the inside cover, to see in a year or two whether mine end up among them.

October 2, 2025. Gémenos, landscaper

He told me in July that he wasn't chasing anybody because he was on a mower all day, and with two crews to keep busy I could see his point. So the agent chases for him.

He phoned this morning to ask whether it had been selling behind his back, because his third quarter came out at 19 signed quotes out of 61, against 14 of 58 in the second, and I had to tell him that all it does is what he did when he remembered: an email four days after a quote and another at ten, at the same prices and with him still answering the phone.

Before agreeing to do his invoices as well I looked up how common the problem is, and the Federal Reserve's 2024 Small Business Credit Survey has 51% of the 7,625 employer firms that answered naming uneven cash flow as a financial challenge, a category in which the Fed includes collecting receivables. His second agent goes through his Pennylane export (the French QuickBooks) at 6 every morning, sends a polite reminder on anything three days overdue and a firmer one at fifteen, and asks him before sending a third.

In the second month it chased a client for €1,840 that the client had paid by check the day before, and the reply ("I paid you yesterday, is this a joke?") was forwarded to me without a word. I called the client to apologize. Since then an invoice has to show as unpaid on two exports 48 hours apart before the agent writes.

October 9, 2025. La Ciotat, electrician

His quotes went out six days after the visit on average in 2024, and when I asked him why, in August, he said he did them on Sunday nights from a catalog of 1,200 lines and didn't want to do them any other night. From this morning a voice note of about two minutes, recorded in the van after the visit, gives the agent enough to put a priced draft in his invoicing software by the evening. The set-up came to €900 for twelve days, then about €15 a month for the model, mostly transcription.

A 2023 supplier price that nobody had updated sent three quotes out 12% too cheap a few weeks later, and he called me to ask who had put 2023 prices in there, before figuring out that he had. When I saw him in August 2026 he showed me that month's bill, €14.20, and said that since October his quotes have left within 24 hours and that by his count the ones he sends the next morning are signed nearly twice as often.

2026

March 31, 2026. Vitrolles, trucking company

I advise against this kind of agent more often than any other, yet last October I built one for a trucking company with 22 trucks, and it reads about thirty sources every morning, among them the French public procurement bulletin and three trade federations' newsletters, so that at 7 he gets ten lines on the bids and rule changes in his sector.

When he asked me back then how he would know it was working, I said he might never know, so I was relieved this morning when he estimated that two bids between October 2025 and March 2026 would have slipped past him without an agent that costs him about €25 a month.

In the first weeks he stopped reading it altogether because the summaries ran to 40 lines, so we cut them to ten.

April 8, 2026. La Ciotat, physical therapy practice

The owner of the practice by the harbor, three therapists, one receptionist and one landline, was sure they didn't miss many calls, so we agreed to count for four weeks in March, and she went quiet when it reached 41 a week, almost all between noon and 2, while the receptionist was at lunch. From Monday a voice agent will answer whenever nobody has picked up by the third ring, to book or cancel appointments and take messages for the therapists.

What worried her was medical advice, so at 7:40 this morning I called it with an invented bad back and asked which stretches to do, and it told me it couldn't advise me but could have a therapist call me back in the afternoon. I'd quoted her €85 to €130 a month for the line and the voice on top of the €900, because voice uses about ten times the data of text.

June: three to six missed calls a week, mostly from people who hang up when they hear it isn't a person. In its first week it had given 30-minute slots to patients who needed 45, which was my doing, as I'd never scripted the question about why they were coming. There's an example of a voice agent interface in my portfolio.

May 12, 2026. Near Marignane, pergola maker

The owner called from her car to say that our agent had told a customer his pergola motor was under warranty for five years. It's two. She only found out because he wrote back to thank her. I went through the logs over lunch.

Of the fourteen PDF manuals we had given it, three give different warranty periods for that motor, and it had used the longest. Since this afternoon it answers only from its knowledge base, and when the answer isn't there or two documents contradict each other the email goes to a person; I'm adding the same rule to the other agents this week.

She had warned me the inbox was chaos, yet when we went through a month of it, two-thirds of the 60 to 80 emails a day that come in during April and May (a lot for fourteen employees and a WooCommerce store) were one of the same six questions, mostly when the pergola is coming and what to do when the remote stops working. The agent answers those six itself, quoting the page or the manual its answer comes from, and drafts the rest for the after-sales person.

In the 2025 high season an email waited 26 hours on average, and this year it's four minutes for the six usual subjects and about five hours for everything else, which gave the owner back the Thursdays she had asked for at our first meeting. It cost €1,400 and three weeks, €500 more than usual, because their after-sales software has no API, and it runs at €20 to €45 a month.

May 26, 2026. Aubagne, accounting firm

The Census Bureau's Business Trends and Outlook Survey, which asks firms every two weeks whether they used AI in the last two weeks, put the figure for the period ending May 3, 2026, at 19.8% of American businesses, with 37% among firms with 250 people or more and under 20% among the tiny ones with four employees or fewer, and that counts somebody asking ChatGPT to rewrite a newsletter.

Also today, I put the French public holidays into the shared calendar at the accounting firm in Aubagne, because yesterday, May 25, was Whit Monday and their agent had booked a client in for it (it was Memorial Day in the US as well).

The firm has seven employees and about 400 clients, and since January the agent has been booking and moving their appointments and texting each client the day before with the papers to bring, and no-shows have gone from 9% in the last quarter of 2025 to 2% by March.

Reading the notebook back

Each of the seven breakages took less than an hour to fix, because I was reading the logs on those mornings.

Clients usually want to start with the agent they'd most enjoy describing at dinner, and I talk them around to the problem that is losing them customers, so a phone that rings out at lunch gets the receptionist first, inquiries that wait half a day get the qualification agent and quotes that leave a week after the visit get the quote agent, with monitoring left until last. I wrote down how I choose, with a before-and-after figure, in AI automation: where to start, and for building one yourself there is my comparison of n8n, Make and Zapier for AI agents.

If you would like a second opinion on which of the seven fits your business, if any, book a fifteen-minute call.

FAQ

What is the best AI agent use case for a small business?

The ones that touch revenue have paid for themselves fastest at my clients, which means the Cassis agency's inquiries, where showings went from 22% to 31% of requests, and the electrician's quotes, sent within 24 hours instead of six days.

Can an AI receptionist replace a front desk?

It covers lunch and the evenings, but I wouldn't let it replace the person, since three to six callers a week at the La Ciotat practice still hang up on the synthetic voice. If one call can be worth ten sessions, keep a human from 8 a.m. to 7 p.m. and leave the agent the nights, the weekends and the lunch break.

How much do AI agents for small business cost?

From €900 before tax at my studio, about $1,000, for the first one, set up in one to three weeks, then the model bill, which for the seven businesses above runs from about €15 a month for the electrician's quotes to €130 for the therapy practice's voice agent with the phone line. Software without an API costs more to set up, €1,400 at the pergola maker.
