The AI tool stack for a small business: start with what you already pay for

Most small businesses need four tools or fewer: an AI assistant, a place for the team to talk, maybe a way to connect your apps, and a place for customer info. Before you add any of them, list what you already pay for and count the parts you actually use, because the cheapest stack is usually the one you already have.

Prices below are from each vendor's own pricing page, checked this month. Hope this helps.

Before you buy anything

Same order I use for everything: learn what you have, pick a tool if one fits, build what's missing.

List every subscription. What it costs, who uses it, and which tabs anybody actually opens.

Look for the overlaps. Two tools doing the same job is the easiest money you'll ever save.

Count the shared logins. If people share a password to save on seats, that tells you the tool doesn't fit your budget or your team. It's also a security risk, so fix it either way.

The tools I'd look at, and what they cost

Four jobs, one tool each, with this month's list prices.

Claude (or ChatGPT)

An AI assistant. For writing, research and thinking things through. Claude Pro is $20 a month, or $17 a month billed yearly. For a team, Claude Team seats are $25 a month each, or $20 billed yearly, and run under business terms.

Slack

Where the team talks. Free to start. Pro is $8.75 per person a month, or $7.25 billed yearly. Business+ is $18, or $15 billed yearly. If your team lives in email or texts and it works, you might not need it.

Zapier or n8n

Connecting apps. Zapier has a free plan, and paid plans start at $19.99 a month billed yearly ($29.99 monthly). n8n's self-hosted version is free if someone can keep a server running, and its cloud plan starts at 20 euros a month billed yearly.

A CRM, maybe

Where customers live. Could be HubSpot, GoHighLevel (from $97 a month) or a simple system built around how you work. HubSpot Marketing Hub Professional is $800 a month on a yearly plan with 3 seats, plus a required $3,000 onboarding fee, so that's the big jump.

A made-up example, real prices. A five-person shop on Slack Pro paid monthly (5 × $8.75 = $43.75), Claude Pro for the two people who use it most ($40), and Zapier's free plan comes to about $84 a month. Add HubSpot Marketing Hub Professional (yearly plan, 3 seats) and the same shop is past $880 a month, plus a $3,000 onboarding fee. That jump is the one to think hard about.

What I'd skip for now

1. Training your own AI model. You almost certainly don't need it. A good assistant plus your own templates and notes covers most of what people want from this.

2. Two AI assistants per person. Pick one for the team and learn it properly.

3. Whatever launched this week. Claude, ChatGPT, Slack and Zapier all keep adding AI features to plans you may already pay for. Check those before adding a new app.

What AI tools does a small business actually need?

Usually four or fewer: an AI assistant, a place for the team to talk, maybe a way to connect your apps, and a place for customer info. Before buying any of them, list what you already pay for and see what it can already do.

Should we build custom AI tools or buy off the shelf?

Buy off the shelf first. Build when nothing fits, or when the learning curve and support load of an existing tool outweigh the time it would take to build the piece you actually need.

Zapier or n8n?

Zapier if nobody on your team wants to think about servers. n8n if someone technical is around and you want to self-host for free. Start with whichever one your team will actually maintain.

Do we need a CRM?

Maybe not a big one. I think CRMs are overrated. Unless yours has to connect to a lot of other software, a simpler system that fits how you actually work is usually better.

Is it okay to share one AI login across the team?

I'd skip it. Shared logins to save on seats are one of the most common things I find, and they're a security risk. Everyone on the account can also see everyone else's chats. Buy the seats or pick a tool that fits your budget.

When you don't need me

Picking off-the-shelf tools is something you can do yourself.

Your stack is small and your team uses all of it. That's the goal. Leave it alone.

You just need to cancel a few things. An afternoon with your card statement will do it.

An off-the-shelf tool fits and you're willing to learn it. Buy it, learn it, and skip the custom build.
