Someone pitches you an "AI agent" for your business. You ask how much it
costs. You get "it depends", a discovery call, and a number that only
appears after you've sat through a sales deck. Here's the honest version
of "it depends", with real prices attached, not a funnel.

## The short answer

For a UK small business, a genuinely useful automation or AI agent project
typically starts in the low thousands, not the tens of thousands. The
range depends entirely on scope: a single automated workflow can be live
in around two weeks from roughly £1,950. A proper custom system or AI
agent built to last starts from £4,500. If you don't yet know what's worth
automating, an Automation Opportunity Audit starts the whole process for
£450, and that fee comes straight off if you go on to do the work with us.
Those are our own published prices, not industry averages, but they're a
real, current UK data point for what this actually costs when a vendor
tells you the truth up front.

## Why "it depends" isn't a dodge, but it's also not an excuse

The honest reason cost varies is that "AI agent" covers wildly different
amounts of engineering. A script that reads an inbox and drafts a reply
for a human to approve is a different job from a system that ingests
messy client data, matches identities across records, and writes back into
three other platforms. Vendors who say "it depends" and then refuse to
give you *any* number until you've sat through a call aren't protecting
you from a bad estimate. They're protecting their pricing from comparison.

## What actually moves the price

- **How much human review stays in the loop.** More judgement calls kept
  with a person costs more to build (proper approval flows, audit trails)
  but usually costs less in risk. We build this in by default, not as an
  upsell: a human makes every decision and takes every call on anything
  that matters.
- **How many systems it has to talk to.** One clean workflow between two
  tools is a Sprint-sized job. A system that has to reconcile data across
  four platforms and keep them in agreement is a Build.
- **Data quality going in.** Clean source data is cheap to automate on top
  of. Messy, duplicated, inconsistent data (which is most small
  businesses, honestly) needs a records layer built first, which is real
  work, not padding.
- **What "properly built" actually includes.** Audited, monitored, backed
  up and tested infrastructure costs more up front than a demo that only
  has to survive one meeting. It's also the difference between something
  that's still running in six months and something that quietly breaks the
  first busy Monday.

## What that looks like against a real number

We built a self-service AI product for a diversity & inclusion consultancy
that replaced a **£300–400 consultant engagement** with a **£10–80
self-service task, completed in minutes instead of hours**. That's not a
cost estimate for a generic AI agent. It's the real economics of one
[shipped product](/work/debiaser-ai-product/), included here because it's a
useful sanity check: a well-built AI product doesn't just move a task from
a person to a machine, it can fundamentally change what the task costs the
customer, because the delivery model changed, not just the labour.

## A quick way to sanity-check any AI agent quote you're given

Ask three questions before you sign anything:

1. **Can you show me this running in production somewhere, today, not in
   a slide deck?** If the answer is no, you're paying for a prototype, not
   an agent.
2. **What happens when it gets something wrong, and who signs off before
   it acts?** If there's no human in the loop for anything that touches
   money, customers, or compliance, that's a red flag, not a feature.
3. **Is the quote a real number, or a range that only becomes real after a
   sales call?** A vendor who can't give you a ballpark before a meeting
   usually has a reason not to.

## Our own answer, published, not pitched

- **Automation Opportunity Audit:** from £450. Fee credited against any
  project you go on to do.
- **Workflow Sprint:** from £1,950. 1–3 automations live in around two
  weeks.
- **System / Agent Build:** from £4,500. A proper custom system or AI
  agent, built to last.
- **AI Ops Partner:** from £495/month, cancel anytime. We keep it running
  and keep automating the next thing.

Full detail on what's included at each level is on our [services and
pricing page](/services/). If you're not sure which one fits, start with
the Audit. That's exactly what it's designed to answer.
