AI Agents: A Practical
Guide
What they are, how they work, and whether they belong in your business. No hype, no jargon.
What is an AI Agent?
An AI agent is software that can complete tasks autonomously. Unlike a chatbot that responds to prompts, an agent can be given a goal and work out how to achieve it: breaking the task into steps, using tools, making decisions, and iterating until done.
Think of it as the difference between asking a colleague a question versus asking them to handle an entire task. One gives you an answer. The other gets it done.
How Agents Differ from AI Assistants
ChatGPT and similar tools are excellent for generating ideas, drafting text, and answering questions. Agents are what you build when you want AI to take action.
AI Assistant
- — Responds to your prompts
- — Session-based memory
- — Works from training data
- — You drive the interaction
AI Agent
- + Completes tasks autonomously
- + Maintains context and tracks progress
- + Uses tools: apps, APIs, files, browsers
- + You set the goal, it drives itself
What Can Agents Actually Do?
Every agent performs some combination of three core actions: perceive (gather information), decide (make choices based on that information), and act (do something in the real world).
Most business processes are variations of these three steps repeated. That's why agents are useful: they map naturally onto how work actually gets done.

Finance & Accounting
Invoice processing, expense categorisation, report generation, anomaly detection.
HR & People
Policy Q&A, onboarding documentation, interview scheduling, benefits queries.
Is This Right for Your Business?
AI agents aren't a universal solution. Here's an honest framework for evaluating fit.
Good Candidate Tasks
- The task happens repeatedly
- It involves moving information between systems
- Human judgement is needed, but not constantly
- Errors can be caught before causing problems
Less Suitable Tasks
- Requires nuanced relationship management
- The process changes unpredictably each time
- Highly sensitive data without proper governance
- No clear, documented process exists yet
The best predictor of success: being able to clearly describe the task, step by step. If you can explain it, it can probably be built.
Where to Start
The most common mistake is trying to automate too much too soon. Start small.
Identify one repetitive task
Something that takes meaningful time and doesn't require constant judgement calls.
Document it
What triggers it? What information is needed? What does success look like?
Get a second opinion
Talk to someone who builds these. Validate whether it's a good candidate.
Most successful agent projects start with a conversation and a single use case, not a transformation strategy.
