Operations
Operations teams often see the fastest return because the work is repetitive and well-defined.
- Extracting data from invoices, delivery notes and forms into your systems.
- Summarising long reports, meeting recordings and email threads.
- Searching internal documents and procedures in plain language.
- Drafting standard operating procedures from existing notes.
Sales and marketing
AI helps sales and marketing teams spend less time on admin and more time with customers.
- Researching prospects and summarising their business before calls.
- Drafting personalised outreach, proposals and follow-ups.
- Creating first drafts of blog posts, social content and product descriptions.
- Updating CRM records automatically from calls and emails.
Customer service
The best customer service AI supports your team rather than replacing the human touch.
- AI assistants that answer common questions from your knowledge base, around the clock.
- Suggested replies for support agents to review and send.
- Automatic ticket categorisation, prioritisation and routing.
- Summaries of customer history before an agent picks up a case.
Finance and HR
These areas often involve sensitive data, which makes tool choice and data privacy particularly important.
- Reconciling transactions and flagging anomalies for review.
- Drafting management report commentary from the numbers.
- Screening and summarising job applications against clear criteria.
- Answering staff questions about policies and benefits.
AI agents: the next step
AI agents go beyond answering questions. They can carry out multi-step tasks such as researching, updating systems and sending notifications, with a human approving key steps. They work best on well-understood processes that have already been simplified and documented.
Frequently asked questions
What business processes can AI automate?
AI works best on repetitive, language- or document-heavy tasks: data extraction, summarising, drafting, searching information, categorising requests and answering common questions.
Will AI replace our staff?
In our experience, AI is most successful when it removes tedious work so people can focus on higher-value tasks such as customers, decisions and relationships, rather than replacing roles outright.
