AI agents work differently. They receive an objective and decide the steps, drawing on tools and data you connect them to. An agent can qualify an inbound enquiry, check the CRM for history, draft a tailored response and flag the edge cases for a person.
Because agents exercise judgement, they cost more to build well, which is why the agent range runs from USD 40k to 90k over six to ten weeks. In practice the two complement each other.
Automation handles the predictable moves, agents handle the moments that need interpretation, and both plug into the same systems through integrations.
When you compare quotes from any provider, ask which of the two you are actually buying, because the words automation and agent often get used interchangeably by teams selling only one of them.
