How Much Does AI Cost for a Small Business?
Most Australian small businesses start with AI for around $30 to $50 per person per month, through a business subscription to an AI assistant or AI features added to software they already use. Custom work costs more: an assistant trained on your own information or an automation connecting several systems typically ranges from about $5,000 to $30,000, plus ongoing usage costs. The right budget depends on the job you want AI to do, not on the technology.
The four levels of spending
These are broad planning ranges in Australian dollars at the time of writing. Prices for AI tools change often, so treat them as a starting point.
| Level | Typical cost | What you get |
|---|---|---|
| AI assistant subscriptions | $30–$50 per person a month | A general assistant for drafting, summarising, research and analysis, with business data terms |
| AI features in existing software | $0–$40 per person a month | AI add-ons in email, accounting, CRM, meeting and office software you already pay for |
| Off-the-shelf AI tools | $50–$500 a month | Ready-made chatbots, transcription, writing or support tools set up with your information |
| Custom assistants and automation | $5,000–$30,000+ to build | AI connected to your own systems and data, restricted to your information and tested for your use |
Most small businesses get useful results from the first two levels. The third and fourth make sense once a specific, repeated job is clear.
Subscriptions: the cheapest place to start
A business plan for a general AI assistant is the simplest step. It covers drafting quotes and emails, summarising documents, analysing spreadsheets and preparing first versions of proposals and policies.
Pay for a business plan rather than letting staff use free personal accounts. Business plans generally offer clearer terms about how your data is handled and whether it is used to train models, which matters for your obligations under the Privacy Act. Our article on the risks of using AI in business covers this in more detail.
You rarely need a seat for everyone on day one. Start with the people who write, quote or report the most.
AI already inside your software
Many businesses are already paying for AI without using it. Email platforms, accounting software, CRMs, video meeting tools and office suites have added AI features, sometimes included and sometimes as a paid add-on.
Before buying anything new, check what your current software offers: meeting summaries, email drafting, transaction categorisation, report writing or reply suggestions. Turning on a feature you already pay for is the cheapest AI project there is.
Off-the-shelf tools
The next level is a dedicated AI product for one job, such as a website chatbot, call transcription, customer support replies or document processing. These are usually priced as a monthly subscription, sometimes with usage limits.
They suit businesses whose needs match what the product does. The costs to watch are setup time, usage limits that trigger higher tiers and the effort of keeping the tool's information up to date.
Custom assistants and automation
Custom work is worth considering when an off-the-shelf tool cannot connect to your systems, cannot be restricted to your own information, or cannot handle your volume. Typical projects include:
| Project | Typical build cost |
|---|---|
| Automation that moves details from emails or forms into your systems | $3,000–$15,000 |
| Customer or staff assistant that answers from your own content | $8,000–$30,000 |
| Document search across manuals, policies or contracts with source references | $10,000–$30,000 |
| AI features built into your own product or platform | $20,000–$80,000+ |
What moves the price is the same as for any software: how many systems are involved, how messy the source information is, how much testing is needed and what happens if the AI gets something wrong. An internal tool that drafts replies for staff to check is far cheaper to make safe than an assistant that talks directly to customers.
The running costs
AI has an ongoing cost profile that surprises some businesses:
- Usage costs. Custom AI features usually pay per use of the underlying AI model. For most small business volumes this is tens to a few hundred dollars a month, but it grows with usage.
- Hosting and storage for any custom system.
- Keeping information current. An assistant answering from your price list is only as good as the price list. Someone needs to own updates.
- Testing after changes. AI models are updated by their providers. A feature that worked well can behave differently after an update, so important uses need periodic checks.
- Support and improvements as you learn what customers and staff actually ask.
A reasonable planning figure for a custom assistant is 10–20% of the build cost per year for running, monitoring and improvements, plus usage.
Working out whether it is worth it
The useful comparison is not "AI versus nothing". It is AI versus the cost of the work it replaces or speeds up.
A simple calculation:
- How many hours a week does the task take now?
- What does an hour of that person's time cost the business?
- What share of the task can AI realistically take on? Be conservative. Half is often more realistic than all of it.
- Multiply for a year, and compare with the subscription or build cost plus running costs.
If a task takes ten hours a week at $50 an hour and AI can take half of it, that is about $13,000 a year. A $40 subscription pays for itself in days. A $15,000 custom build pays for itself in a little over a year, if the estimate holds. Test on real examples before committing to the bigger number.
Frequently asked questions
How much does business AI cost per month?
Most small businesses start at around $30 to $50 per person per month for a business subscription to an AI assistant. AI features in existing software range from included to about $40 per person per month, and dedicated off-the-shelf AI tools typically cost $50 to $500 a month.
How much does a custom AI chatbot cost for a small business?
A custom assistant that answers from your own content and is tested for your use typically costs about $8,000 to $30,000 to build in Australia, plus ongoing usage and support costs. Off-the-shelf chatbot tools are cheaper to start, usually $50 to $500 a month, but offer less control.
Are there ongoing costs with AI?
Yes. Custom AI usually has usage costs that grow with volume, plus hosting, keeping the source information current, testing after model updates and ongoing improvements. A reasonable planning figure is 10–20% of the build cost per year, plus usage.
Is free AI good enough for a business?
Free AI tools are fine for trying ideas and general drafting, but businesses should avoid entering client, health or confidential information into free consumer tools. Business plans usually offer clearer data-handling terms, which helps you meet your privacy obligations.
