# AI agent use cases

> The best first AI agent use cases are repetitive, documented and bounded, with a clear definition of done and mistakes that can be reversed: support triage, internal help desks, lead enrichment, invoice matching, report preparation and scheduling all fit. In each, the agent reads your systems, drafts or completes the routine cases within limits, and routes the exceptions to a person with the evidence attached.

## At a glance

- **What qualifies:** Work that repeats, follows written rules, has a clear finish and can be checked or reversed by a person.
- **What the agent needs:** Read access to the systems of record, a way to draft or act within limits, and a queue to hand exceptions to.
- **Where people stay:** Approvals above a limit, anything irreversible, and the cases the agent flags as unsure.
- **Best first pick:** The use case with the highest volume of routine cases and the cheapest mistakes, usually internal or draft-only.

Most teams can name a dozen tasks that feel automatable and struggle to say which one an agent should take first. This library groups the common use cases by function, shows what the agent does in each, what it needs access to and where a person stays, and helps you pick a first one that will earn trust.

## What makes a task a good AI agent use case?

A good use case is repetitive, documented and bounded, with a definition of done and a way to catch mistakes. Volume makes it worth doing; reversibility makes it safe to start.

An agent is handed a goal and a set of tools and works out the steps. That makes it good at work that varies in its details but not in its rules: the request is different every time, the procedure is not. It also means the agent is only as good as the rules it can read and the systems it can reach. A task that lives in one person's head, or in a system nobody can connect to, is not ready however tedious it is.

The second test is what happens when the agent is wrong. Early on it will be wrong sometimes, and the question is whether a person can catch and reverse the mistake cheaply. A draft reply can be rejected. A record can be edited. A wired payment or a legal notice cannot. Start where mistakes are cheap and move towards the expensive ones as the log earns it.

- The process has a written procedure, or someone could write one in an afternoon.
- The information the agent needs lives in systems it can be given access to.
- There is a clear definition of done that a person can check quickly.
- Mistakes can be caught and reversed: a draft rejected, a record edited, a message held.
- The volume is high enough that minutes per case add up to real hours.

## Which AI agent use case should you start with?

Answer four short questions about where the time goes, who the work touches, whether the rules are written down and how reversible a mistake is. The result is a first use case, not a final one.

_Interactive on the web page: Find a first use case. The pathfinder asks where your team's repetitive time goes, whether the requests come from customers or colleagues, whether the rules are written down somewhere an agent could read, and whether a mistake could be caught and reversed. Teams with documented, reversible customer work are pointed to support triage; internal requests and scheduling point to an internal help desk; copying invoices or contacts between systems points to invoice matching or lead enrichment; and where the rules live in people's heads it recommends starting with report preparation, where the agent reads and summarises rather than decides, so that the rules get written down through review._

## What are the common AI agent use cases by business function?

Customer service, sales, finance and operations, and internal support each have a small number of well-worn use cases. In every one the agent reads, drafts or completes within limits, and a person keeps the decisions that carry risk.

| Use case | What the agent does | Needs access to | Where a person stays |
| --- | --- | --- | --- |
| Support triage | Classifies each case, looks up the customer and order, drafts or completes routine replies | Help desk, order system, policy documents | Refunds, complaints, anything above the limit |
| Order and returns handling | Checks eligibility against policy, creates the replacement or return as a draft | Order platform, returns policy, shipping records | Approval above a value limit, disputed cases |
| Lead enrichment | Fills gaps on new leads, scores against written criteria, drafts the first reply | CRM, inbound forms, approved data sources | Sending, pricing, any promise to the prospect |
| Quote follow-up | Chases open quotes on a schedule, answers stock and lead time questions from the record | CRM, quoting tool, inventory | Discounts and terms |
| Invoice matching | Extracts fields, matches the invoice to purchase order and receipt, posts clean matches | Accounts payable, purchasing, document store | Payment approval, every mismatch |
| Report preparation | Pulls the figures, writes the narrative, flags what changed since last time | The systems of record and the last report | Interpretation and the decisions the report leads to |
| Internal help desk | Answers policy and how-to questions from your documents, raises the right ticket | Handbook, IT and HR knowledge, ticketing | Anything about a named individual, access grants |
| Scheduling | Finds times, books rooms and visits, sends confirmations, reschedules on request | Calendars, booking rules, contact records | Conflicts between priorities, sensitive meetings |

Across functions the shape is the same. The agent needs read access to the system of record before it needs anything else, and the person stays wherever a decision is irreversible, involves money above a limit, or concerns a named individual. If you cannot fill in the last column for a candidate use case, you have not finished designing it.

## Which use cases are not ready for an AI agent?

Anything where the rules are unwritten, the action cannot be undone, or the decision is really about a person. Those can be supported by an agent that prepares the case, but not handed to one.

- **Negotiating price or terms** The agent can prepare the history and the limits; a person makes the offer.
- **Hiring, performance and disciplinary decisions** An agent can schedule and summarise, but a decision about a person needs a person, and the rules for what it may summarise need care.
- **Anything that moves money without a second check** Payment runs, refunds above a limit and changes to bank details need approval by design, not by exception.
- **Processes nobody can describe** If two experienced people disagree about the steps, the agent will pick one and be wrong half the time. Write it down first.
- **Regulated advice** In legal, medical and financial contexts, an agent can find and cite the source material; a qualified person gives the advice.

## How do you choose between several candidate use cases?

Score each candidate on volume, documentation, access and the cost of a mistake, then pick the one that is highest on the first three and lowest on the last. Ties go to the one whose owner wants it most.

1. **List the candidates with an owner each** A use case without a person who runs the process today is not a candidate.
2. **Count the volume** Cases per week and minutes per case. Small numbers can still be worth it if the work is painful, but say so explicitly.
3. **Check the rules and the access** Is the procedure written? Can the systems be connected read-only this month? A no on either pushes the candidate down the list.
4. **Price the mistake** What does the worst plausible error cost, and how quickly would you notice? Prefer cheap and visible over expensive and quiet.
5. **Pick one and define done** Write the definition of done and the limits before anyone builds. The second candidate is the plan for next quarter, not a parallel project.

## Frequently asked questions

**Q: What is the easiest AI agent use case to start with?**  
A: Usually an internal one: a help desk that answers policy and how-to questions from your own documents, or report preparation that reads your systems and drafts a summary. Both have cheap mistakes, obvious owners and a natural review step, and they build the integrations you will reuse for customer-facing work.

**Q: Do AI agent use cases need custom software?**  
A: Not always. Many run on integrations to the systems you already have, with the agent's tools, limits and review queue as the custom part. Custom software becomes the answer when the process has no system of record, or when the review and hand-off need an interface your existing tools cannot provide.

**Q: How many use cases should we start with?**  
A: One. A second process is far cheaper once the integrations, the review habit and the audit trail exist, so the fastest route to several use cases is to finish the first one properly.

**Q: Can one agent handle several use cases?**  
A: Technically yes, but it makes permissions, limits and measurement harder to reason about. Treat each use case as its own agent with its own limits, even if they share tools and a model. It is easier to pause one, widen one and explain one.

**Q: How do I know a use case is working?**  
A: Measure the same things before and after: volume handled, time per case, backlog, rework and how often the agent's drafts go out unchanged. If the acceptance figures climb and the exceptions the agent raises are the right ones, it is working. If reviewers approve everything without reading, it is not being measured.
