The short version. ChatGPT or Claude is the first purchase and the only one most small businesses genuinely need. HubSpot’s free CRM is the customer record, and it costs nothing. Zapier removes the copying-between-apps work you are currently doing by hand. Tidio answers customers at eleven at night. Canva produces the marketing. Total for a working stack: well under $100 a month, and two of the five have real free tiers.
Prices below were read off each vendor’s own pricing page on 15 August 2026, except Canva (verified 9 August 2026) and the assistant tier. OpenAI’s page blocked our request, so we describe rather than quote it.

The five jobs we ranked against
The average small business now runs around five AI tools, and that number is the problem rather than the achievement. Five subscriptions arrived one at a time, each solving something narrow, and most owners could not say what any single one saves them.
This list is built the other way round: what are the five jobs a small business actually loses money on, and what is the cheapest credible tool for each. So we weighted:
- Does it replace an hour you are personally working? Not an hour in theory, an hour on your own calendar this week.
- Is there a real free tier? Small businesses have lumpy cash. A tool you can start on for nothing and pay for when it proves itself is worth more than a marginally better one with a card up front.
- Does it work without anyone technical? If setup needs a developer, the price is not the price.
- Does it survive you being busy? The tools that fail in small businesses are the ones needing weekly attention. The ones that work run whether or not you look at them.
We have deliberately not included anything industry-specific. Your trade’s software matters more than everything here. This is the layer that sits on top of it.
1. ChatGPT or Claude: best because it is five tools you did not buy
Both sell an individual tier around $20 a month, with usable free tiers. We describe rather than quote: OpenAI’s pricing page returned a 403 to us on 15 August 2026.
If you buy one thing on this page, buy this, and give it a fortnight before adding anything else. The reason is not that it is the most impressive. It is that it absorbs the jobs you would otherwise buy four separate subscriptions for.
Concretely, for a business with no marketing department and no assistant: quotes and proposals from a rough description, the awkward email to a late-paying customer, a policy document you have been putting off, product descriptions, replies to reviews, summarising a contract before you sign it, and turning a voice note recorded in the van into something you can send.
The common failure is treating it as a search engine. It is not one, and it will produce a confident wrong answer about a regulation, a price, or a legal deadline. Use it for things where you can tell whether the output is right. Which is most business writing, and none of the questions where you would otherwise call your accountant.
Who it’s wrong for: nobody, at this price. But it is wrong used as an oracle for anything regulated. Tax treatment, employment law, licensing. Those answers arrive with the same confidence as everything else and are wrong often enough to be expensive.
2. HubSpot’s free CRM: best because it costs nothing and stops leads dying
Free tier $0/month for up to 2 users, no card required. Starter is listed at $7 per seat per month against a normal price of $20 per seat per month. Verified 15 August 2026.
The most expensive thing in a small business is the enquiry nobody followed up. It cost you money to generate, it went into an inbox on a busy day, and it is now four hundred emails down. Every business that has ever said “we don’t really need a CRM” is losing money exactly here.
The free tier is genuinely free rather than a trial, and it is more than enough: contacts, deals, email tracking, forms. The AI layer sits on top of that record, and this is the important part. An assistant that knows who your customers are and what you last discussed is a different tool from one starting from a blank page every time.
Start free. The upgrade decision makes itself when you can see the pipeline you are currently guessing at.
Who it’s wrong for: businesses with no repeat custom and no enquiry pipeline. A walk-in-only shop is not going to benefit. Also be careful about the seat pricing before you put a growing team on it; this is a product designed to become expensive later, and that is a fine trade if you make it deliberately.
3. Zapier: best for the copying-and-pasting nobody should be paid for
Free tier with 100 tasks a month. Professional starts at $19.99/month billed annually for 750 tasks ($29.99 month-to-month), scaling by task volume. $49/month annually at 2,000 tasks, $89 at 5,000. Team plans start at $69/month annually for 2,000 tasks. Verified 15 August 2026.
Every small business has two or three routines where a human moves information between systems that could talk to each other. A form submission that has to become a CRM contact. An invoice paid that should trigger a thank-you. A booking that needs to reach a spreadsheet the team actually looks at.
Each of these takes ninety seconds and happens forty times a month, which is why nobody ever fixes them. Zapier connects the apps you already use, and the honest scope is small: two or three automations that each remove a recurring irritation. That is the whole win, and it is a real one.
Price on tasks, not on the headline. A task is one action, so a single automation firing forty times a month is forty tasks. The free tier’s 100 tasks covers one modest routine; most small businesses land comfortably in the $19.99 tier and stay there for years.
Who it’s wrong for: businesses running one system that already does everything. If your trade software handles bookings, invoicing and customers, there may be nothing to connect. And building automations for their own sake is a hobby that bills monthly.
4. Tidio: best for answering customers at eleven at night
Free tier with 50 conversations and 50 one-off Lyro AI conversations. Starter $24.17/month for 100 billable conversations. Growth from $49.17/month for 250+. Plus from $300/month. Verified 15 August 2026.
Most enquiries arrive outside working hours, and most of them are the same six questions: are you open, do you cover my area, how much roughly, do you do this particular thing, how soon, can I book. A visitor who does not get an answer goes to whoever answers.
Tidio’s Lyro answers from your own content, your pages, your FAQs, rather than making things up, which is the distinction that decides whether a support bot helps or embarrasses you. Set up is a form and some copy rather than a project.
The pricing detail that matters is the AI conversation allowance, not the chat widget. Free and Starter include a one-off block of Lyro conversations rather than a monthly one, so the free tier is a trial of the AI in practice. Watch that number, because it is the thing you will run out of.
Who it’s wrong for: businesses whose enquiries are genuinely bespoke. If every question needs a quote based on a site visit, a bot answers nothing useful and adds a layer between you and a customer who wanted a person. Also anything regulated, where a wrong answer given confidently at midnight is a liability rather than a saved call.
5. Canva: best for the marketing you keep not doing
Free tier. Pro for individuals. Canva Business at $20 per person per month with no seat minimum; Canva Teams is closed to new signups. Verified 9 August 2026.
The realistic alternative for most small businesses is not a designer. It is nothing. A social account last posted to in March and a flyer made in Word in 2019.
Canva’s value is that the output is sized correctly, on brand, and finished. Set up a brand kit once with your colours, logo and fonts, and producing a month of posts, a price list and a van sticker becomes filling in templates rather than making design decisions you are not equipped to make.
The free tier is substantial and many small businesses never need to leave it. Upgrade when the brand kit and background remover start mattering, not before.
Who it’s wrong for: businesses with an existing brand identity built by a designer. Work in their files or you will erode it within a year. And it is not a substitute for photography; good templates around bad photos advertise a business that looks worse than it is.
Businesses this list won’t help
Businesses without their industry software sorted. If your booking, invoicing or job management is still on paper, fix that first. It will do more than everything here combined.
Ecommerce sellers. Your problems are product photography, order support and inventory cash, which is a different stack. We have a separate list for that.
Regulated professions. Clinics, law firms and financial advisers have data handling obligations that change which tools are permissible, not just which are useful.
Anyone hoping AI fixes demand. Every tool here helps you serve customers or reach them more efficiently. If the phone is not ringing, that is a market or pricing problem, and a subscription is a comfortable way to avoid looking at it.
What we left off, and why
Jasper, Copy.ai and the dedicated writing tools. They wrap the same models a general assistant gives you, at a comparable or higher price, with a narrower surface. For a small business owner rather than a marketing team, the assistant wins on breadth.
Mailchimp and the email platforms. Genuinely useful, and left out because email marketing is a discipline rather than a tool. Buying the platform without the list or the habit is the most common wasted subscription in small business.
Bookkeeping AI. Real and valuable, and inseparable from which accounting software you run, which is not a decision this list should make for you. Ask your accountant, who has an opinion and will have to work in it.
AI phone answering services. Improving quickly and worth watching. Today the failure mode, a confident wrong answer to a customer who thinks they spoke to your business, is more expensive for a small firm than a missed call.
Owner questions
What should a small business buy first?
An assistant, at around $20 a month, and nothing else for a fortnight. Use it daily on real work, then look at which of the remaining four jobs still hurts. Most owners find they need two of these five, not all of them, and the two are not the ones they expected.
How much should a small business spend on AI tools?
The stack described here runs well under $100 a month at small-business volumes, with two genuinely free tiers in it. If you are spending more than that and cannot name what each subscription replaces, you have accumulated tools rather than chosen them, which is the normal way it happens.
Is it safe to put customer information into these tools?
Check the data handling terms and, if you are in a regulated field, your obligations. Consumer, business and API tiers of the same product often treat data differently. As a general rule, avoid pasting anything into a general assistant that you would not be comfortable seeing outside your business, and keep customer records in the CRM, which is designed to hold them.
Can AI replace hiring my first employee?
It can defer the admin part of that hire, and that is worth real money. It cannot answer the phone like a person, turn up to a site, or take responsibility for anything. Businesses that use these tools to stay lean a little longer do well. Businesses that use them to avoid hiring past the point where they need someone burn the owner out instead.
Do I need a chatbot if I answer my own enquiries?
Only if enquiries arrive when you cannot answer them. Evenings, weekends, while you are on a job. If you reliably respond within the hour during working hours and that is when people ask, a bot adds a barrier and removes nothing.
Why isn’t there a dedicated AI writing tool on this list?
Because you would be buying a prompt. Those products wrap the same underlying models, and for a business owner writing across quotes, emails, policies and marketing, the general assistant covers all of it for the same money.
