Buyer's guide
AI software for small business: how to choose it and what it should cost
Most owners do not need more AI capability. They need the invoice chased, the quote sent and the month planned. This page sorts the categories of AI software on the market, what each realistically costs, and the five questions to ask before you pay for any of it.
The four categories, and what each is good for
| Category | Typical cost | Where it fits |
|---|---|---|
| General assistants | $0 – $30 / user / month | Drafting and thinking out loud. Starts blank every time, so you re-supply your prices, terms and tone. |
| Single-purpose point tools | $30 – $60 each / month | One job done well. Five of them is $200+ a month and five logins nobody keeps up with. |
| Bolt-ons inside your CRM or accounting app | $10 – $40 / month | Useful summaries of data already in that app. Will not write your quote or your collections sequence. |
| AI back office (CEO Engine) | $49 – $399 / month | 9 departments in one subscription, each returning a finished document built from your saved profile and client records. |
Market rates are indicative ranges for US service businesses, not quotes. CEO Engine pricing is our own.
Five questions before you buy
- — Does it hand back finished work, or a draft you still have to rewrite?
- — Does it remember your prices, terms, trade and tone without being told again?
- — Can a non-technical owner set it up in one sitting, with no integrations?
- — Is there a real trial, so you can judge the output before committing?
- — Does one subscription cover several jobs, or does each job add a bill?

Common questions
What is the best AI software for a small business?
The one that removes recurring paperwork rather than adding a tool to learn. For service businesses that means collections, quoting, follow-up, pricing, marketing and forecasting — the work that currently eats evenings.
How much should AI software cost a small business?
Budget $50 to $400 a month in total. Below that you are usually buying a general assistant you have to prompt yourself; far above it you are paying for enterprise features a 5 to 30 person company never touches.
Do I need to integrate anything?
No. CEO Engine is set up by filling in one business profile, then typing what you need in plain language. Members who use HubSpot can connect their own account read-only so client records and unpaid totals flow into briefs.
What does the output actually look like?
A finished, sendable document: a three-step invoice-chasing sequence with send days, a priced itemised quote with scope and exclusions, a month of marketing copy, or a written cash-flow forecast with the tight weeks flagged.
Judge it on the output, not the demo
Three free days, card required, nothing charged before day four.
