QUICK ANSWER

What drives the cost of building an AI agent — scope, integrations, volume and governance — with typical ranges and how to budget for a pilot.

KEY TAKEAWAYS
✓Cost is driven mainly by integrations and the number of actions an agent can take.
✓A focused pilot is the lowest-risk way to prove value.
✓Running costs (model usage, hosting, monitoring) should be budgeted from day one.

Build costs vs running costs

Build covers design, integrations and testing. Running costs include AI model usage, hosting, monitoring and improvements. Usage-based model costs are usually small compared with staff time saved, but must be tracked.

Start with a pilot

Pick one workflow, set a success metric (for example tickets resolved or hours saved) and run for 4–8 weeks before scaling.

Common mistakes to avoid

✕Treating AI visibility as a one-off project instead of a monthly habit
✕Describing your business differently on every profile and page
✕Publishing generic AI-written content with no first-hand expertise
✕Blocking AI crawlers by accident in robots.txt or firewall rules

Frequently asked questions

Can I use an off-the-shelf chatbot instead?

For simple FAQs, yes. Custom agents make sense when you need access to your own systems and actions.

How long does a pilot take?

Typically 3–6 weeks to build and 4–8 weeks to measure.

Who owns the agent?

You do — code, prompts and configuration are handed over.
