What does a conversation handled by the AI look like?
Example conversation
Automatic door company AI agent
Customer: My store door got stuck open, can you come today?
AI agent: I'm logging the call now: send me the store address, the equipment and what is happening.
AI agent: A jammed door is treated as a priority and goes to the technician for your region.
Is an AI agent or manual customer service better for automatic door companies?
The agent wins at repetitive tasks, and people keep winning at what takes judgment. With manual service, someone at the automatic door 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 |
|---|---|---|
| Stopped door service call | Customer calls several times during peak hours | Answered right away, with location, equipment and symptom logged |
| Identifying the customer and the equipment | Asked from scratch on every call | The contact is already linked to the contract and the equipment in the CRM |
| Preventive maintenance under the contract | Booked by phone when someone remembers | The agent confirms the date with the person in charge and records the approval |
| New door quote | Waits until sales has time | Qualified right away: clear opening, door type, traffic and location |
| Contract renewal | Remembered after it has already expired | The agent starts the conversation before the expiration date |

Get started now
Create my agentWhat needs to be ready before turning the agent on at the automatic door company?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The list of contract customers, with location, door type and brand of the operator
- What counts as a total stoppage and what is a defect that can wait, written with the symptoms of each
- The response time promised in the contract and what applies to one-off customers
- The data sales needs for a new door: clear opening, leaf type, foot traffic and type of location
- The preventive schedule per customer and who signs the approval at each location
Whether the agent sends total-stoppage calls straight to the technician for the region, or everything goes through the dispatch center first.
The most common mistake: Treating a contract customer's call as a new lead. They already answered these questions when they signed, and redoing everything with the store shut down is what makes contracts go unrenewed. Read how to fix this.
Frequently asked questions from automatic door companies
Does the agent solve the technical call?
No. It answers right away, identifies the customer and the equipment, and passes it on to the technician. The service itself is still done by your team.
Does it tell contract customers apart from one-off customers?
Yes. The contact is linked to the contract in the CRM, and you set different priorities and terms for each case.
Is it useful for selling new doors, not just maintenance?
Yes. It qualifies clear opening, door type, foot traffic and location, and hands your sales team a ready request to build the proposal.
Does it know which technician covers each region?
It knows based on what you configure. The call goes out with location, equipment and symptom already written, directed to the route of the technician for that region, with nobody relaying it by phone.
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?

In short
