Operations
AI agents vs automations: the difference for a service business

Zapier moves a field. An agent watches a queue. Mixing them up is how operators buy the wrong thing.
Zapier moves a field. An agent watches a queue. Mixing them up is how operators buy the wrong thing and then decide AI is theater.
An automation is a trigger and an action. Lead arrives, create a contact. Invoice paid, send a receipt. Fine. Necessary, even. It does not notice that an estimate aged past the window, or that the same customer called twice and nobody called back.
An agent has a job. Watch stalled repair orders. Watch unsold estimates. Assemble the morning briefing. It reads more than one system. It decides whether something is an exception. It drafts, flags, or, where you approve it, takes a small action. Then it logs what it did.
You still want automations. They are cheaper and more reliable for the dumb paths. The mistake is asking ChatGPT plus a zap to run the shop. Glue cannot respect permissions, keep a history, or get better as the operation changes. That takes architecture, testing, and someone watching the watchers.
In the audit we mark which stalls are automations, which are agents, and which should stay with a person. If a path needs taste or a hard conversation, it is not an agent job. If it is a field moving from A to B, it is not an agent job either.
