The short version
Most small businesses can get meaningful value from AI for somewhere between £0 and a few hundred pounds a month. The tools themselves are cheap; the cost that matters is the time it takes to set them up properly and connect them to how you actually work.
Think of it in three buckets: free tools you use yourself, paid tools that run in the background, and the one-off cost of getting it all set up so it actually saves you time instead of becoming another thing to manage.
1. Free and near-free tools
Tools like ChatGPT, Claude, and the AI features now built into software you already pay for (your email, your accounting package, your booking system) cost little or nothing. For drafting emails, summarising documents, or answering a quick question, this is often all a sole trader needs.
The catch: free tools only help if you remember to use them and know how to ask. The value is real but it lives entirely in your own time and habit.
2. Paid tools that run in the background
This is where it gets interesting for busy businesses. An AI receptionist that answers missed calls, a system that chases unpaid invoices, a bot that handles 'where's my order?' — these typically run from £20 to a few hundred pounds a month depending on volume.
The way to judge the price is simple: what's the cost of the problem today? If missed calls lose you one £500 job a month, a £100/month tool that catches them pays for itself five times over.
3. The real cost: setup and fit
The biggest variable isn't the monthly fee — it's getting AI set up so it fits your business and your customers. Done badly, it frustrates customers and creates more work. Done well, it quietly saves hours every week.
This is the part a consultant helps with: working out which one or two things are worth automating, choosing tools that won't lock you in, and setting them up so they sound like you. It's usually a one-off cost, not a forever one.
So what should you actually budget?
If you're testing the water: £0 and a few hours of your own time. If you want something running in the background that genuinely saves hours: budget a modest monthly tool cost plus a one-off setup. The mistake to avoid is paying for clever software that never gets used because nobody set it up to fit how you work.
Frequently asked questions
- Is free AI like ChatGPT good enough for a small business?
- For drafting, summarising, and answering your own questions, yes — free tools go a long way. You'll outgrow them when you want something running automatically in the background, like answering calls or chasing invoices without you doing it.
- Do I need to pay a consultant, or can I set it up myself?
- You can absolutely start yourself with free tools. A consultant earns their fee when you want AI working automatically and fitting your business — choosing the right tools, avoiding lock-in, and setting them up so they actually save time rather than create work.
- What's the cheapest way to start?
- Pick the single most repetitive task in your week and try a free AI tool on it for a fortnight. If it saves you real time, that's your signal to do it properly.
