For a one-person business, an AI assistant costs a monthly subscription (Claude Pro starts at $17/month) plus real setup effort, while a human virtual assistant charges by the hour and the cost scales with every hour you use. The honest distinction isn't cost alone: a human VA brings judgement and can act on your behalf, while an AI assistant does legwork - drafts, research, briefings - faster and at a fraction of the price, with your judgement staying firmly in the loop. Many one-person businesses do best starting with AI for the legwork and hiring humans later, for the work that genuinely needs a person.
Here's the comparison in full, including the parts that don't flatter either option.
A VA charges for time. Rates vary widely with experience, specialism and location, so check current rates where you are rather than trusting a number in an article. But the structure of the cost is the point: every hour of help is an hour billed.
For illustration only: at £30 an hour, five hours of help a week comes to roughly £650 a month, or close to £8,000 a year. Change the rate and the hours to fit your reality; the shape stays the same. The cost scales linearly with use, and it never stops.
You also pay in coordination. A VA needs briefing, managing and enough steady work to stay worth retaining. For a business that needs help in bursts - a heavy fortnight, then a quiet one - you either pay for hours you don't use or spend time negotiating hours you suddenly do.
None of this is a criticism of VAs. It's what buying human time costs, and human time is worth it for the right work.
A subscription plus effort. Claude Pro starts at $17/month with annual billing ($20 monthly), billed in US dollars by Anthropic - we've broken down what Claude costs a small business in detail, including the caveats. That price doesn't change whether you use it five hours a week or twenty-five, which is the structural difference from hourly help: the marginal hour is free.
The honest part is the effort. A subscription alone buys you a clever generalist that knows nothing about your business. Making it useful takes a real setup: teaching it your business, your voice and your files, then testing it before you trust it. Done properly, that's about a fortnight of sessions for a first role - a chief of staff that knows your whole business - and about a month to a small working team. Front-loaded effort, no shortcut, and anyone who says otherwise is selling something.
Where a human VA wins, clearly:
Where an AI assistant wins, clearly:
Where you should be sceptical of both pitches: an AI assistant, properly set up, should never post, send or spend on its own. Everything arrives as a draft, a briefing or a list for you to review - your name goes on the work, so your judgement stays in the loop. That's a design principle, not a flaw. If a product promises an AI that runs your business while you sleep, put it down.
Ask what you're actually short of. If the answer is judgement, presence and hands - someone to take the phone calls and handle the humans - that's a person, and no software truly replaces them.
If the answer is hours - the drafting, the research, the summarising, the tidying, the planning that eats your evenings - that's legwork, and legwork is exactly what an AI team is for at a fraction of hourly rates.
For many one-person businesses the sequence that works is AI first, human later. Build the AI team to absorb the legwork now, at subscription prices. Then, when you do hire human help, you hire for the genuinely human work rather than paying someone by the hour to format documents and dig through folders. The two aren't rivals; they're different tools for different jobs, and the mistake is paying human rates for machine work or expecting machine judgement to be human.
Three, stated plainly:
A VA has catches too - cost that scales, availability, the management overhead - but you likely knew those already. The AI catches are the ones the adverts skip.
The difference between an AI subscription that pays for itself and one that gets cancelled in month three is almost always method. Build My AI Team is a guided method that takes a non-technical person from zero to a working AI team on Claude in about a month: a chief of staff first, then roles you choose from a catalogue, each tested before it goes live, with a proper filing structure underneath so it still works at month six.
One-time purchase, £119, 12 months of updates included, no subscription to us. The Claude plan is a separate cost, billed by Anthropic, and we say so upfront. Built on Claude, not affiliated with or endorsed by Anthropic. If your evenings are currently full of machine-shaped work, it's worth a look.
