How to choose an AI agent developer
Ask every vendor these five questions before you sign. The answers separate builders from resellers of a chatbot widget.
- What systems will the agent read from and write to? A good answer names your CRM, calendar, inbox or ticketing tool and explains how permissions work.
- Can I see one live agent you built? A demo account or a public product beats a slide deck.
- What happens when the agent doesn't know the answer? Look for a defined handoff to a person, with the conversation attached.
- How will we measure it? You should get a dashboard showing conversations, leads captured, bookings or hours saved, not just message counts.
- Who owns the prompts, data and code? You should, in writing, with no lock-in to the vendor's platform.

What's the difference between an AI chatbot and an AI agent?
A chatbot answers questions in a chat window. An AI agent can also take actions, such as booking appointments, updating records and sending follow-ups, through connections to your other software.
How much does a custom AI agent cost?
Published pricing varies widely. Simple website chatbots can start in the low thousands of dollars, while multi-system agents with custom integrations commonly run into five or six figures. Ask for a fixed-scope first phase.
How long does it take to build an AI agent?
A focused agent for one workflow, like lead qualification or appointment booking, can launch in a few weeks. Agents spanning several departments usually roll out in phases over a few months.
Can an AI agent qualify leads and book sales calls?
Yes. This is one of the most common uses: the agent answers questions, asks qualifying questions, captures contact details and books a call directly on a sales rep's calendar.
