What does a conversation handled by the AI look like?
Example conversation
Metalworking shop AI agent
Customer: How much is a tilt-up gate?
AI agent: Send me a photo and the measurements of the opening. With that, I'll book the technical visit to measure.
Customer: Do you serve my neighborhood?
AI agent: Send me the address and I'll check it and offer you your open slots.
Which is better for metalworking shops: an AI agent or manual customer service?
The agent wins at repetitive tasks, and people keep winning at what takes judgment. With manual service, someone at the metalworking shop has to stop what they're doing; with the CertuAI agent the answer goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Gate request while the welder is running | Quote waits until the job is done, and the customer has already called another shop | Type, opening, material and photo collected right away, without stopping the shop |
| Measuring visits | Out of sync, each one in a different corner of the city | Organized by region and day, with the address confirmed |
| "Is my gate ready yet?" | Calls interrupting production to give the same answer | Stage and installation date answered on their own |
| Urgent stuck-gate call | Goes into the regular queue and the customer is stuck in the garage | Recognized by your rules, priority slot and immediate alert |
| Maintenance of an installed motor | Customer only comes back when the gate stops for good | Periodic service offered at the right time to customers who had one installed |
