AI in a small business: where it pays and where it bites

We run AI across our own operations every day. This is what has worked, what has not, and the six controls we would not operate without.

By Richard Yeo, Director, Fortis Business Advisory

Where it genuinely saves time

  • Drafting: quotes, specifications, proposals and routine correspondence from your own templates and price lists
  • Answering staff questions from your own procedures, product data and past jobs, so people stop interrupting the owner
  • Triage: sorting enquiries, summarising calls and flagging what needs a human
  • Extraction: pulling data from supplier invoices, delivery notes and forms into your systems
  • Commentary: turning management accounts into a readable first draft of the monthly narrative

The pattern is consistent: AI is strongest where there is a lot of text or data in a known format, a clear template for the output and a human who checks it before it leaves the building.

Where it goes wrong

  • Confident, fluent, wrong. A model will state an incorrect price, date or regulation with complete confidence. Unchecked output is a liability.
  • Data leakage. Pasting customer, staff or financial data into a consumer tool may put it outside your control. Use business-grade services with clear data terms.
  • Tools bought on a demo. A licence per user per month across the company, used by three people after the first quarter.
  • Automating a broken process. If the process is wrong, AI makes it wrong faster.
  • No ownership. Nobody accountable for the output, no audit trail, no idea what the model was given.

The question is not whether to use AI. It is which specific task, with which data, checked by whom, and measured how.

Six controls before you start

  • A business account on a service that does not train on your data, with data held in the UK or EU where possible
  • A written list of what data may and may not be used, and who can use the tools
  • A human check on anything that goes to a customer, HMRC or a regulator
  • An audit trail: what went in, what came out, who approved it
  • One named owner for each AI-assisted process
  • A measure: hours saved, error rate or turnaround time, reviewed quarterly

Where to start

Pick one process that is high volume, text-heavy and low risk. Drafting quotes from a template is a classic. Run it for a month with a human check, measure the time saved and the error rate, then decide whether to extend. Most businesses find two or three processes where AI pays clearly, and that is enough to matter.
