What does a conversation handled by the AI look like?
Example conversation
Company AI agent
Customer: Do you do post-construction cleaning? How do you quote it?
AI agent: We do. To quote it, tell me the square footage and the condition of the property, and I'll apply the price list.
Customer: Are you available on Friday?
AI agent: On Friday I have your open slots. What's the address?
Which is better for cleaning companies: 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 company 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 |
|---|---|---|
| Post-construction quote request | Answered at the end of the day, when the customer has already gotten three quotes | Square footage and property condition collected right away, price and date settled |
| Schedule for several crews | Clashes between WhatsApp and phone, two crews in the same neighborhood | Day jobs fitted by crew and region, in organized windows |
| Weekly or biweekly customer | Cancels once, nobody confirms the next one, the recurring job dies | Each visit confirmed ahead of time, and whoever paused is reactivated |
| What's included in the day rate | Explained from scratch every time, and it turns into an argument on the day of the job | Scope and extras answered the same way every time, in writing |
| Quote with no reply | Forgotten in the conversation, customer goes with another company | Automatic follow-up days later reopens the negotiation |
