What does a conversation handled by the AI look like?
Example conversation
Glass shop AI agent
Customer: How much is a standard bathroom shower enclosure?
AI agent: The standard shower enclosure is your price. If it's not standard, send me the measurements and a photo of the bathroom.
Customer: Do you come to the site to take measurements?
AI agent: We do. I have your open slots for measuring in your area.
Which is better for glass 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 glass 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 |
|---|---|---|
| "How much is a shower enclosure?" with no measurement or photo | Messages going back and forth through the day until you have what you need to quote | Measurements, model and photo requested in the right order, quote ready to close |
| Price-list item, like a standard shower enclosure or a mirror by the meter | Customer waits for an answer to a price that never changes | Answered right away, straight from your price list |
| Booking the measuring visit | Three calls to find a time that works | Booked in the conversation, with time window and address confirmed |
| Order follow-up | Customer asks about the date every week and someone stops to check | Stage answered on its own, with notice when the glass arrives |
| Quote sent with no reply | Gets forgotten and the customer disappears | A polite follow-up reopens the conversation within a few days |
