Quick verdict: A small business does not need twenty AI subscriptions. It needs six jobs covered — thinking/writing, organization, automation, design, polish and client admin — and in 2026 that entire stack costs $63 a month if you choose the right tier of each tool (annual billing, prices verified below). Start at $0 with the free stack, move to the $63 Core Stack when the business is paying you, and add the final two tools to reach the $98 Growth Stack only when client volume demands it. Every tool and price in this guide was checked on October 14, 2026.
The three stacks at a glance
| Stack | Monthly cost | What’s in it | Who it’s for |
|---|---|---|---|
| Starter | $0 | ChatGPT free · Fathom free · Canva free · Make free | Pre-revenue and testing the waters |
| Core | $63/mo | ChatGPT Plus $20 · Notion Plus $10 · Make Core $9 · Canva Pro ~$12 · Grammarly Pro $12 · Fathom free | Most small businesses — the sweet spot |
| Growth | $98/mo | Everything in Core + Bonsai Essentials $19 + Descript Hobbyist $16 | Client-heavy and content-led businesses |
Monthly figures use annual-billing equivalents (the way these tools are cheapest). Pay month-to-month instead and the same stacks run roughly 30–50% more — the single easiest way to overspend on AI tools is refusing annual plans for tools you use daily.
The six jobs every small business stack must cover
1. Thinking and writing — ChatGPT Plus ($20/mo)
Your general-purpose brain: emails, proposals, product descriptions, spreadsheet formulas, brainstorming, first drafts of everything. Plus at $20/mo is the tier with the strong models and none of the ad-supported compromises of the cheaper $8 Go tier (which may include ads — a strange look for business work). Claude Pro (from $17/mo billed yearly) is the legitimate alternative if your business writes long documents all day; we compared both in depth in our freelancers guide. Pick one — never both.
2. Organization — Notion Plus ($10/mo billed yearly)
Client pipelines, project trackers, SOPs, content calendars, a wiki your future hire will thank you for. One trap to dodge: Notion’s full AI features live in the $20/mo Business tier, and Plus includes only an AI trial. For most small businesses the organization alone justifies $10 — let ChatGPT do the AI heavy lifting and skip the upgrade until a team member needs workspace-wide AI search.
3. Automation — Make Core ($9/mo billed yearly)
The stack’s best value, and it isn’t close. Core’s 10,000 monthly credits cover lead capture, invoice reminders, review requests, order sync and reporting for most businesses. Our Zapier vs Make cost test priced the same workloads on Zapier at $49–129/mo; choose Zapier only when a niche app connection forces your hand. This is where the under-$100 stack is won or lost.
4. Design — Canva Pro (~$12/mo billed yearly)
Social graphics, presentations, menus, ads, one-page flyers — the design department for businesses that will never hire one. Pro runs $18/mo monthly or roughly $144/yr annually; Canva has adjusted prices several times since 2024, so confirm the live annual figure at checkout. The free plan is strong enough for the Starter stack; Pro earns its place when brand consistency and the full template/AI library start saving real hours.
5. Polish — Grammarly Pro ($12/mo billed yearly)
The quiet professionalism tool: it sits in your browser, inbox and documents catching the errors that make a small business look small. $12/mo billed yearly (the $30 month-to-month price is not the deal). If every customer-facing word passes through it, it’s the cheapest credibility you can buy.
6. Meetings — Fathom (free)
Client and sales calls record, transcribe and summarize themselves. Fathom’s free plan is unlimited for recording and transcription (advanced AI summaries capped at 5 calls a month) — good enough that it stays free in all three of our stacks. Our notetaker comparison covers when the $16/mo Premium or a rival makes sense; for most small businesses, not yet.
The Growth Stack additions (+$35/mo)
Bonsai Essentials ($19/mo billed yearly) — client admin
Contracts, proposals, invoices and payments in one freelancer-and-small-business-shaped tool. Note there’s no free plan (7-day trial) and the $9 Basic tier lacks the invoicing/contract features that are the whole point — Essentials is the honest entry price. Add it when client paperwork eats more than an hour a week.
Descript Hobbyist ($16/mo billed yearly) — content
If the business markets with video or a podcast, Descript’s edit-by-transcript workflow is the fastest route from recording to published. Hobbyist (10 media hours/mo, no watermark) covers a weekly show or regular social video; Creator ($24/mo) is the step up when volume grows. Businesses that don’t publish video should skip this entirely — a stack is only cheap if every tool is used.
What we deliberately left out (and why)
- A second AI assistant: ChatGPT or Claude, never both — overlapping subscriptions are the #1 stack leak.
- Zapier: priced out by our cost test for any business with growing automation volume; revisit only for a must-have app connection.
- AI image generators as separate subscriptions: Canva’s built-in AI covers small-business design needs; standalone image tools are a creator expense, not a business one.
- Enterprise anything: if a tool’s pricing page says “talk to sales,” it’s not for this stack.
How to roll this out without the subscription sprawl
Week 1: run the $0 Starter stack on real work. Week 2–3: upgrade the two tools you touched daily (usually ChatGPT and Make) to Core tiers. Month 2: add design and polish. Add Bonsai and Descript only when a specific weekly pain — client paperwork, video editing — proves it deserves $16–19/mo. Then audit quarterly: any tool nobody opened in 30 days gets cancelled at renewal, no sentimentality. Stacks stay under $100 by subtraction, not by hoping.
FAQ
What is the single best AI tool for a small business?
A frontier AI assistant — ChatGPT Plus ($20/mo) for breadth, Claude Pro (from $17/mo billed yearly) for writing-heavy businesses. It’s the one subscription that touches every department. After that, automation (Make, $9/mo) returns the most hours per dollar.
Can a small business really run on free AI tools?
Yes, at the start: ChatGPT free + Fathom free + Canva free + Make free (1,000 credits/mo) covers the essentials with no watermarks on your client calls or designs. The caps you’ll hit first are AI summary limits and automation volume — both are good problems, because they mean the business is busy.
Why does annual billing matter so much?
Because the gaps are unusually large in AI tools right now: Descript charges roughly 50% more month-to-month, Grammarly is $12/mo billed yearly versus $30 monthly, and Make and Notion follow the same pattern. Rule: one month monthly to validate, then commit yearly.
How much should a small business budget for AI tools per employee?
Our Core Stack works out to $63/mo for the business’s shared core; per-seat tools (Notion, Grammarly) scale with headcount while Make and Fathom largely don’t. A 3-person business should expect roughly $85–110/mo all-in — still less than one hour of most professionals’ billed time.
