AI agents vs automation vs AI integration: which do you need?
Short answer: an automation follows fixed rules, an AI agent can read and make sense of messy input and do a job, and AI integration is the wider work of connecting AI, often several agents, into how your business runs. LuxxStack builds all three. Use an automation for simple, predictable steps, an agent for one job that needs judgement, and integration when several teams or systems are involved.

Key points
- Automations are cheap and reliable when the input is predictable.
- Agents cope with variety, such as emails, receipts and enquiries.
- Integration joins them up with your systems and your people.
- Whatever you choose, keep a person approving what matters and keep someone running it.
The three, side by side
| Automation | AI agent | AI integration | |
|---|---|---|---|
| What it does | Follows fixed rules | Reads, decides and prepares one job | Connects several agents and systems across a business |
| Copes with messy input | No | Yes | Yes |
| Example | When a form is submitted, add a row to a sheet | Read an incoming receipt, check it and queue it for review | A recruitment agency with compliance, bookings, portals and chasers working together |
| Needs a person approving | Rarely | For anything sensitive | For anything sensitive, with an audit trail |
| Typical LuxxStack price (excl. VAT) | Typically £2,500 to £15,000 for a workflow | Typically £2,500 to £15,000 | From £15,000 |

When you need which
An automation is enough when the steps never change. A form comes in, a row is added, an email goes out. There is no judgement involved.
You need an agent when the input varies. Every client writes differently. Receipts come in as photos. Enquiries leave out the important detail. An agent reads them, works out what is missing and asks.
You need integration when the work crosses teams or systems. If one job triggers three more, and each lives in a different tool, you want them designed together, with shared records, approvals and access by role.
A middle path: the managed AI teammate
Not every business needs a project. A managed AI teammate, sometimes called an AI employee, is one AI agent set up around your business, connected to your tools and looked after by us. It starts from £295 a month plus setup, and it is a low-risk way to see how this works before you commit to more. Read what an AI employee is.
What matters whichever you choose
- Approvals. Anything that goes to a client or costs money waits for a person.
- A record. Every action is logged.
- Someone running it. Workflows change and tools update. Most agencies build and hand over. We build it and then run it.
