The StackWriting

The AI tool stack for a one-person business, and what it costs a month

Five jobs a solo operator actually has to do, the smallest set of tools that does each one, and the monthly total — including which subscriptions to delay until something is earning.

A one-person business has the same jobs as a company with thirty people: build the thing, publish, sell, run the admin, and know what is working. The difference is that you do all five, and you pay for all five out of the same pocket.

This is the stack I keep for that, grouped by the job rather than by the category — because nobody wakes up needing "an AI tool". They wake up needing a payment page that works before Friday.

Every price here is indicative and changes; the full list carries the current one, with what each tool is for.

Start here: four tools, about €40 a month

Before anything else, you need to be able to make something, put it somewhere, remember what people did, and take money.

The assistant for everything elseClaude~€20/mo

Taking the moneyStripeFree, % per sale

Two of those are free until you have real traffic, and the other two replace a stack of things you would otherwise buy. If you never add another tool, you can still build and sell a product with this.

The most expensive stack is not the one with the priciest tools. It is the one with five subscriptions nobody cancelled. Add a tool against a measured problem, then check a month later whether it fixed it.

If you do not want to touch a terminal

The browser builders do the same job with a different surface. You describe what you want, they produce something that runs, and you fix what leaks.

Whichever you pick, check the export path before you build something a business depends on. That is the difference between a tool and a landlord. The six ways these apps leak — and the security pass that takes an afternoon — are in The Vibe Coding Playbook.

Publishing video every day

This is where people overspend first, so be specific about the bottleneck. If the problem is quality, a phone and daylight fix it for free. Pay when the bottleneck is volume, consistency, or a second language.

Cutting and captionsCapCutFree, Pro ~€10/mo

Roughly €50 a month across the set, and you can run the first month of it for nothing. Check the commercial licence on the plan you buy before you monetise anything narrated by AI.

Running the business on AI

The half of the work nobody enjoys: notes, documents, decks, the follow-up you forgot.

Before you connect any agent to your accounts, decide what it is allowed to touch. The rule that has never cost me anything: an agent gets the access a new freelancer would get on day one, and no more.

Selling something physical

Keeping customers and follow-ups in one placeRiibaseFree tier, then paid

About €60 a month plus sampling — and this is the one stack where the tools are the cheap part. The unit economics decide whether the business exists; the software only decides how pleasant it is to run.

Knowing what actually works

The cheapest habit on this list. Two tools, and one of them is free:

If you only measure one thing, measure which links people click. It is the best content research you will get, and it costs nothing.

What this adds up to

StageStackRoughly
Nothing earning yetStart-here four~€40/mo, mostly free tiers
Publishing daily+ video set~€90/mo
Selling a physical product+ store and sourcing~€100/mo plus sampling
Client work at volume+ agents, notes, documents~€150/mo

Four numbers, and every one of them is smaller than a single freelancer invoice. The tools are not what makes this hard.

The three rules that keep it small

  1. Add against a problem you measured, not against a problem you read about. Then check a month later whether it actually fixed it.
  2. Cancel on a schedule. Once a quarter, an hour: anything you have not opened in a month goes, and anything replaced by something else in the stack goes with it.
  3. Never let a tool hold the only copy. Check the export before you depend on it — contacts, content, code. That single check is what separates a subscription from a hostage situation.

The whole list

58 tools, what each costs and when you actually need it. Updated twice a year.

Questions people ask

What AI tools does a one-person business actually need?

Four to start: an assistant, somewhere to put things live, somewhere to store data, and a way to take money. That is roughly €40 a month and most of it is free until you have traffic. Everything else should wait until a specific problem forces it.

How much should I spend on AI tools per month?

Under €50 while nothing is earning, and add tools only against a measured problem. The stacks in this piece land between €25 and €70 a month each, and the expensive part is almost never the AI — it is the five subscriptions nobody cancelled.

Is it cheaper to buy one AI subscription that bundles everything?

Only if it replaces at least two things you already pay for. Bundles that cover writing, images, video and voice run around $30 a month, which beats four separate €20 subscriptions and loses to one tool you actually use.

What should I cancel first?

Anything you added without a measured problem, anything you have not opened in a month, and any tool whose job is now done by something else in the stack. Run that check once a quarter; it takes an hour and it usually pays for the next quarter.

Do I need to pay for AI video tools to publish daily?

Not to start. A phone and daylight outperform polished output on most platforms. Pay when volume, consistency across shots, or a second language is the actual bottleneck — that is a different problem from quality.

Who wrote this. I build software with AI agents, publish video about it, and sell eight playbooks on making money with these tools. Everything here comes from work I have actually done or from the worked examples in those books — and I say which one it is.

Some links are affiliate links: if you sign up through one I may earn a commission, at no extra cost to you. It never decides what is on the list or how it is ranked. Figures here come from the worked examples in the playbooks and from current market rates — they are arithmetic, not a promise.
