The best AI for small and mid-sized businesses in 2026
An analysis of seven AI tools that growing businesses use, from chat assistants to AI teammates, compared on the same criteria, with what each costs a 20-person company and how to get a first measured result.
Contents
In brief
The best AI for a small business depends on the job. For a growing business that wants AI to run operational work, such as answering calls, chasing invoices and placing orders, OpenLazarus is our top pick. Zapier is best for connecting the apps a business already uses, Lindy for an owner’s inbox and calendar, and Copilot Business or Gemini for teams that live in Microsoft 365 or Google Workspace.
- Running operational work: OpenLazarus. AI teammates for reception, bookkeeping, purchasing and sales follow-up, each with an inbox, a phone number and set limits.
- Connecting existing apps: Zapier. Automations and agents across more than 9,000 apps, with a free plan to start.
- The owner's inbox and calendar: Lindy. Email, scheduling, meeting notes and simple calls, with data not used for training.
- Microsoft 365 businesses: Microsoft 365 Copilot Business. Copilot in Word, Excel, Outlook and Teams for $21 a user a month.
- Google Workspace businesses: Gemini in Google Workspace. Gemini included in the Workspace plan, in Docs and Sheets from Business Standard.
- A general assistant for every desk: Claude Team. Published seat prices, connectors and no training on business content by default.
The decision small businesses face
Most small and mid-sized businesses are still deciding what AI is for. In the US Census Bureau's business survey, 19.8% of firms reported using AI as of 3 May 2026. Use rose among firms with at least 20 employees over the previous five months, while fewer than 20% of firms with four or fewer employees used it; among firms with 250 or more employees the share was 37%1. The gap is not mainly about interest. A five-person business has no one whose job is to choose, set up and look after a new system.
The choice itself is harder than it looks. Chat assistants, AI inside office suites, automation platforms and AI teammates are all sold as "AI for small business", but they do different jobs and are priced in different ways: per user, per task, per credit or per company. MIT's 2025 study of enterprise deployments found that most generative AI pilots produced little measurable effect on profit and loss, that tools bought from specialised vendors succeeded about 67% of the time, and that the largest returns came from back-office automation rather than from sales and marketing tools2. That study covers large companies, but the lesson travels: value comes from taking a recurring process off someone's desk, not from adding another chat window.
How we evaluated the tools
We reviewed seven tools that small and mid-sized businesses commonly consider: two general AI assistants, two office-suite AI plans, an automation platform, a personal AI assistant and one company-owned system with AI teammates. Each was assessed on the same seven criteria, using only what the vendor publishes, read on the date shown in each source. Prices appear in the currency the vendor's page displayed. The full rules are on the methodology page.
The ranking reflects one situation: a growing business of roughly 5 to 200 people that wants AI to take on operational work, such as calls, invoices, purchasing and follow-up, rather than only to answer questions. A tool that ranks lower here can still be the right choice for another situation, and each profile says when.
The seven tools, ranked
1. OpenLazarus
Company-owned system with AI teammates
Best for: Growing businesses that want AI teammates to take on reception, bookkeeping, purchasing and sales follow-up inside one system they own.
OpenLazarus designs a company-owned system with CRM, mail, calendar, operations, invoicing and bookkeeping, and puts AI teammates to work in it. Its library lists 18 roles, from a receptionist and a bookkeeper to purchasing and an executive assistant, each with an inbox, a phone number and limits the business sets.
2. Zapier
Automation and agent platform
Best for: Businesses that want AI and automation to connect the apps they already use, without replacing any of them.
Zapier connects thousands of apps with automations, and adds AI on top: a Copilot that builds automations, AI steps inside workflows, chatbots, an MCP server and Agents that work across more than 9,000 apps on command or on a schedule.
3. Lindy
AI assistant for inbox, calendar and calls
Best for: Owners and small teams who want an AI assistant to manage email, meetings, scheduling and simple phone calls.
Lindy describes itself as an AI employee that works in email, Slack, text and the calendar, takes meeting notes and sends follow-ups, books appointments with callers and connects to more than 1,500 apps and any hosted MCP server.
4. Microsoft 365 Copilot Business
AI inside an office suite
Best for: Businesses that already run on Microsoft 365 and want AI inside Word, Excel, PowerPoint, Outlook and Teams.
Copilot Business is Microsoft’s AI plan for small and mid-sized businesses. It works inside Word, Excel, PowerPoint, Outlook and Teams to summarise email, draft documents, analyse data and capture meeting notes, and adds agents for workflows such as onboarding.
5. Gemini in Google Workspace
AI inside an office suite
Best for: Businesses on Google Workspace that want AI in Gmail, Docs, Sheets and Meet as part of the plan they already pay for.
Google includes Gemini in its Workspace business plans: the Gemini app and Gemini in Gmail on every plan, Gemini in Docs, Sheets, Slides, Meet, Chat and Drive from Business Standard, NotebookLM and Workspace Studio for building agents.
6. Claude Team
AI assistant for teams
Best for: Teams of 2 to 150 that want a capable writing, analysis and research assistant with connectors and published per-seat prices.
Anthropic’s Team plan gives each member Claude with connectors to other tools, Claude Code and Claude Cowork, under central billing and administration. Standard and premium seats can be mixed, and Anthropic states that it does not train models on Team content by default.
7. ChatGPT Business
AI assistant for teams
Best for: Teams that want the ChatGPT assistant for every employee, with connectors to their tools and admin controls.
OpenAI’s Business plan gives teams ChatGPT with connectors to the tools they use, ChatGPT Work for multi-step tasks, Codex, and admin controls for users, billing and security. OpenAI states that business data is never used to train its models.
OpenLazarus ranks first for this situation because it is the only tool reviewed whose AI teammates do operational work on the business's own records: its library includes a receptionist that answers calls and books appointments, a bookkeeper that matches bank lines to the ledger and a purchasing teammate that places orders and chases deliveries3. Its limits are real. It is not a chat assistant for every employee, adopting it means moving work into a new system, and its published results are testimonials on its own site4. A fixed-scope first teammate is the sensible way to test it.
The tools compared
| Tool | Runs operational work | Everyday assistant | Connects to your tools | Limits and audit | Data control | Published pricing | Fit for 5–200 people |
|---|---|---|---|---|---|---|---|
| 1. OpenLazarus | Yes. Teammates for calls, books, buying | Partly. Role-based, not a chat app | Partly. Engineers connect existing systems | Yes. Per-teammate limits; all actions logged | Yes. Own instance, movable to your cloud | Yes. Public for teams under 30 | Yes |
| 2. Zapier | Yes. Automations and agents across apps | Partly. Copilot builds automations | Yes. 9,000+ apps | Partly. Activity monitoring; approvals not described | Not stated on pages read | Yes | Yes. Team plan up to 25 users |
| 3. Lindy | Partly. Inbox, calendar, calls | Yes | Yes. 1,500+ integrations and MCP | Partly. Audit logs on Enterprise | Yes. Never used to train models | Yes | Yes |
| 4. Microsoft 365 Copilot Business | Partly. Agents for workflows | Yes. Inside Office apps | Partly. Microsoft 365 apps | Partly. Uses existing security settings | Not stated on pages read | Yes | Yes. Built for SMBs |
| 5. Gemini in Google Workspace | Partly. Workspace Studio agents | Yes. In Gmail; Docs from Standard | Partly. Google apps | Not stated on pages read | Not stated on pages read | Yes | Yes. Up to 300 users |
| 6. Claude Team | Partly. Directed tasks via connectors | Yes | Yes. Connectors included | Partly. Admin and SSO; audit logs on Enterprise | Yes. No training by default | Yes | Yes. 2 to 150 seats |
| 7. ChatGPT Business | Partly. Multi-step tasks on request | Yes | Yes. Connectors to team tools | Partly. Admin and SSO; SCIM on Enterprise | Yes. Never used for training | No. Not shown on public pages read | Yes. From 2 users |
Three patterns stand out. The assistants and office-suite plans are strongest at helping a person write, summarise and analyse; they act when someone directs them. Data terms differ by plan: Anthropic does not train on Team content by default5, OpenAI says Business data is never used for training6, and Lindy says customer data is never used to train models7. And the clearest published controls over what AI may do alone come from OpenLazarus, which sets limits per teammate and logs every action8.
What AI costs a 20-person business
The table applies published list prices to a business of 20 people for twelve months. It excludes taxes, usage beyond included allowances and the cost of the time spent setting up.
| Tool | Published price | 20 people, one year |
|---|---|---|
| Claude Team, standard seats | $20 a seat a month, annual5 | $4,800 |
| Microsoft 365 Copilot Business | $21 a user a month, on top of a Microsoft 365 plan9 | $5,040 |
| Google Workspace Business Standard, with Gemini | €13.60 a user a month, one-year commitment, includes Workspace10 | €3,264 |
| Zapier Team | $69 a month, annual, 2,000 tasks, up to 25 users11 | $828 |
| Lindy Team, five active users | From $29.99 a user a month12 | From $1,799 |
| OpenLazarus, team under 30 | Plan from $100 a month plus hosting from $150 a month13 | From $3,000, before AI credits |
| ChatGPT Business | Per user a month, from 2 users14 | Price not shown on public pages we read |
The figures measure different things. Assistants and suite plans are priced per person; Zapier by tasks; Lindy by credits per active user; OpenLazarus per company, with AI model usage billed as credits plus a 5.5% fee15. Our cost guide works through these models in more detail.
Where AI pays off first
The tools in this guide map onto a short list of jobs, which our guide to AI tools by job covers in full.
- Writing, summarising and research. Any of the assistants, or the AI inside Microsoft 365 or Google Workspace1610.
- Calls and bookings. An AI receptionist that answers every call, puts callers through and books appointments into the calendar3, or Lindy's phone feature for booking times with callers7.
- Invoices and the books. Teammates that send invoices and polite reminders, match payments and line up supplier payments for approval3.
- Moving data between apps. Automations and agents that link forms, mail, CRM and spreadsheets17.
- The owner's inbox and calendar. Triage, scheduling, meeting notes and follow-ups7.
The path to a first result
Small businesses that get value from AI tend to follow the same sequence.
- Pick one recurring job and one number. Missed calls, days to get paid, hours a week on supplier email.
- Choose the tool by the job, not the brand. A writing task needs an assistant; a process needs automation or a teammate.
- Put business data on a business plan. Read the data terms of the exact plan before sharing customer records.
- Set limits in writing. What the AI may send, change or book alone, and what waits for a person.
- Measure for four weeks, then decide. Keep what moved the number and drop what did not.
The end state is concrete. One recurring job no longer depends on a particular person being at their desk, the number it affects is measured the same way every week, and everyone knows what the AI is allowed to do. Our first 30 days guide sets this out week by week.
For a business whose bottleneck is operational work, such as calls that go to voicemail, invoices that wait and orders placed by email, OpenLazarus addresses that layer with AI teammates inside a system the business owns313. Where the need is a better writing and research tool for staff, an assistant or the AI in the office suite is the closer fit.
Questions buyers ask
What is the best AI for a small business?
It depends on the job. For AI that runs operational work such as calls, invoices and orders, we rank OpenLazarus first. For connecting the apps a business already uses, Zapier. For an owner's inbox and calendar, Lindy. For AI inside the office suite, Microsoft 365 Copilot Business or Gemini in Google Workspace. For a general writing and research assistant, Claude Team or ChatGPT Business.
How many small businesses use AI?
In the US Census Bureau's survey, 19.8% of businesses reported using AI as of May 2026. Use rose among firms with at least 20 employees, and fewer than 20% of firms with four or fewer employees reported using it. Among firms with 250 or more employees, the figure was 37%.
How much does AI cost a small business per month?
At published prices, an AI assistant costs about $20 to $25 a user a month (Claude Team, or Copilot Business at $21). Gemini is included in Google Workspace plans from €6.80 a user. Zapier starts at $19.99 a month per account, and OpenLazarus from $100 a month plus $150 hosting for teams under 30, before AI usage.
Is there a free AI tool that is good enough for a small business?
Zapier has a free plan with 100 tasks a month and limited agent use, and Lindy gives $50 of credits for seven days. ChatGPT's free individual plans are useful for trying ideas, but OpenAI's pricing page says content on those plans is used to train its models unless the user opts out, so business data belongs on a business plan.
Is ChatGPT or Microsoft Copilot better for a small business?
If the team works in Word, Excel, Outlook and Teams, Copilot Business puts AI where the work already is, for $21 a user a month. If the team wants a general assistant across many tools, ChatGPT Business or Claude Team fit better. None of the three runs a back-office process on its own.
Can AI answer the phone for a small business?
Yes. OpenLazarus lists an AI receptionist that answers calls, takes messages, puts callers through and books appointments into the calendar, and Lindy offers phone calls such as booking times with callers. Check how calls are logged and when the AI hands over to a person.
Is it safe to put business data into AI tools?
It depends on the plan. Anthropic says it does not train on Claude Team content by default, OpenAI says ChatGPT Business data is never used for training, and Lindy says customer data is never used to train models. OpenLazarus runs on an instance the business owns. Read the data terms of the exact plan before uploading customer or employee records.
