I get asked this a lot. Usually by the owner or MD of a business with somewhere between 10 and 100 people. They've seen the headlines. They know AI is "the future." But they're running a real business with real margins and they want to know if it's actually worth spending money on.
Fair question. Honest answer: it depends.
Not a cop-out. Let me explain what it depends on.
The 10-person rule
Here's a rough rule I use. If you have more than 10 people doing office-based work, there's almost certainly something AI can save you meaningful time on. Not everyone will be affected. Maybe 3 or 4 roles will see real benefits. But those benefits add up.
Below 10, it gets harder. Not impossible, but the savings might be small enough that the cost of setting it up doesn't make sense. If you're a 5-person company and the AI saves you 3 hours a week, is that worth the investment? Maybe. Depends on what those 3 hours are worth.
Above 10, the maths almost always works. Because the same AI setup that saves one person 2 hours a week can usually be applied to 5 or 6 people doing similar work.
When it's clearly worth it
If your team spends significant time on any of these, AI will pay for itself quickly:
Data entry. Typing information from one system into another. Copying from emails into spreadsheets. Entering invoice details. This is the lowest-hanging fruit in any business, and the time savings are immediate.
Document processing. Reading documents, extracting information, filing it. Whether that's CVs, invoices, quality reports, or compliance forms. If someone's reading and summarising documents for more than an hour a day, AI will cut that dramatically.
Report writing. Weekly summaries, monthly reports, anything where someone's pulling data together and writing it up. AI drafts, humans review. The time saving on a single report can be 70-80%.
Repetitive communications. Answering the same customer questions. Sending the same follow-up emails. Drafting responses to routine enquiries. If your team's writing similar emails 20 times a day, AI can draft them in seconds.
When it's probably not worth it (yet)
I believe in being honest about this. AI isn't the answer to everything.
If your problem is process, not efficiency. Sometimes a business is slow because the process is broken, not because the admin takes too long. AI will speed up a broken process, which just means you get the wrong result faster. Fix the process first.
If you don't have the data. AI needs something to work with. If your business runs on phone calls, handshakes, and notes scribbled on the back of a delivery note, there's a step before AI that involves getting your information into a system. Not a huge step, but it exists.
If you're only looking at one person's time. Setting up AI properly costs money. If it's only going to save one person an hour a week, the payback period might be a year or more. That's not necessarily bad, but it's worth knowing upfront.
If you're chasing the hype. "Our competitors are doing AI" isn't a good reason on its own. Maybe they are. Maybe it's working for them. Or maybe they spent £20k on something that nobody uses. Find your own reason.
The cost question
Realistically, getting AI set up for a specific use case in your business might cost somewhere between £3k and £10k. That's for someone to come in, understand your operation, configure the tools, and make sure your team knows how to use them.
Is that worth it? Let's do the maths.
If AI saves 10 hours a week across your team, and you value that time at £20/hour (conservative for any office role), that's £200 a week. £10,400 a year. A £5k investment pays for itself in 6 months and then keeps saving you money every week after that.
That's a simplified version, obviously. There'll be some ongoing costs for the AI tools themselves, usually £50-200/month depending on what you're using. But the maths still works comfortably for most businesses above that 10-person threshold.
What I'd actually do if I were you
If you're curious but not sure, don't spend £10k finding out. Spend £3k on an assessment. Get someone in for a couple of weeks to look at your business and tell you honestly where AI fits, what it'll save, and what it'll cost. If the numbers work, carry on. If they don't, you've spent £3k and you know.
That's how our AI readiness assessment works. Two weeks, honest answers, no pressure to buy anything else. If AI isn't right for your business right now, I'll tell you. I'd rather have that conversation honestly than sell you something that doesn't deliver.
