What does a conversation handled by the AI look like?
Example conversation
Electric fence company AI agent
Customer: My wall is about thirty meters long, how much would it be?
AI agent: For thirty meters, the range is your price. Is it a masonry wall or a grille? What is the height?
Customer: I already have an old fence, can the posts be reused?
AI agent: I'll note that there's already an old fence, so the team can check whether the posts can be reused.
Is an AI agent or manual customer service better for electric fence installers?
The agent wins at repetitive tasks, and people keep winning at what takes judgment. With manual service, someone at the electric fence company has to stop what they are 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 |
|---|---|---|
| Question about price per meter | Answered only when the team comes down from the ladder | Answered right away, using the price list you maintain |
| Finding out the size of the wall | Messages going back and forth for days | The agent asks for meters, height and wall type all at once |
| Service call for a fence tripping on its own | Customer calls several times until someone picks up | Logged right away, with address and symptom, and passed on to the team |
| Difference between fence, razor wire and alarm | Explained from scratch in every conversation | Explained your way, with what you actually install |
| Maintenance for existing customers | Only happens when the customer remembers | The agent starts the conversation on the schedule you set |

Create my agentWhat needs to be ready before turning the agent on at the electric fence company?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The price per installed linear meter, separating fence, razor wire and energizer-only replacement
- What changes the price by wall type: masonry, grille, wood, a tall wall or a lot with curves
- What the company does with an old structure: when the posts can be reused and when it is a full replacement
- The standard explanation about shock, pets and regulations, written the way your company talks
- The installation warranty period and what counts as a maintenance call
- The neighborhoods and cities served and the travel fee outside the radius
Whether the agent books the installation based on the length the customer gave, or whether every installation goes through a verification visit first.
The most common mistake: Keeping one per-meter table for every wall. Grille, tall walls and lots with curves need more posts and more time on the ladder, and a single price closes jobs below cost. Read how to fix this.
Frequently asked questions from electric fence installers
Does the agent close the installation price?
It gives the per-meter range you set and books the visit. The final price comes from you, since you see the wall and the access.
Does it answer questions about shock and safety?
It answers what you write in the Brain, the way your company explains it. Anything outside that, it passes on to you.
Does it work for maintenance calls outside business hours?
Yes. It logs the call at any hour, with address and symptom, and your team finds everything in writing in the morning.
What if the customer doesn't know the length of the wall?
The agent guides the conversation: it asks about the shape of the lot, how many sides have a wall, and asks for a photo. With that you can decide whether to book the visit or ask the customer to measure with a tape.
In what other fields does the CertuAI agent work?
In any business that serves customers on WhatsApp, because the Brain is written by you. These fields have a day-to-day closest to yours.
Where can I read more about CertuAI's WhatsApp agent?
These pages explain the same agent from another angle: how it works, price, common questions and comparisons between platforms.
In short
The first question is how many meters of wall and the price per meter. The agent answers, checks the height and the wall, books the installation and logs it in the CRM.
