What does a conversation handled by the AI look like?
Example conversation
Buffet AI agent
Customer: Do you have availability for March 14?
AI agent: I'll check the date now. Tell me the party type, the number of guests and the location.
Customer: Can we schedule a tasting?
AI agent: Of course. I have your open times for a visit and tasting.
Is an AI agent or manual service better for buffets and party venues?
The agent wins at repetitive tasks, and people keep winning at what takes judgment. With manual service someone at the buffet has to stop what they're doing; with the CertuAI agent the reply goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Quote requested over the weekend | Bride writes on Sunday and waits until Monday, getting quotes from other buffets in between | Date, guests and party type collected right away, visit booked |
| Date already booked | Discovered after a long quote conversation | Calendar checked before any proposal, with nearby alternatives |
| Menu and drink questions | The same packages explained in every conversation | Packages, menus and what's included answered on their own |
| Tasting | Booked through back-and-forth messages over the week | Scheduled in the conversation, based on the times you open up |
| Months-long pipeline until a decision | Proposal forgotten amid so many events | Polite, spaced-out follow-up until an answer, without being pushy |
