AI agents are software that can carry out multi-step tasks on their own, rather than just answering a single question. A customer service agent might read an incoming email, check order status in your system, and draft a reply, while a sales agent could qualify an inbound lead and book it straight into a calendar.
Unlike a basic chatbot that follows a fixed script, an AI agent uses a language model to understand intent and decide what action to take next, often pulling live data from your CRM, booking system or inventory. Good implementations are given clear boundaries so they escalate to a human when a query falls outside what they are trained to handle.
Pricing models vary widely between a flat monthly platform fee, a per-conversation or per-resolution charge, and usage-based pricing tied to the underlying AI model. Most UK small businesses land somewhere between £100 and £800 a month depending on volume and how many workflows are automated.
Handles enquiries and tasks outside office hours without extra staffing cost.
Reads and updates real data in your CRM, calendar or order system.
Hands complex or sensitive queries to a human rather than guessing.
Pricing is usually a platform fee plus usage; figures are monthly for a small business.

Read guideNo. A chatbot follows scripted rules, while an AI agent can understand intent, take multi-step actions and use live data to complete a task.
Under UK consumer protection guidance, businesses should be transparent that a customer is interacting with an automated system.
Accuracy depends heavily on setup quality and how narrowly the agent's scope is defined. Well-configured agents typically resolve routine queries reliably.
Some platforms integrate with payment providers, but most businesses keep payment confirmation as a human-reviewed step for security.
