What changes at a dealership with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. These are four everyday situations at a dealership before and after the Certu Agent.
TodayAn ad lead arrives at 9 p.m. and is only answered the next day, after they have already talked to another dealer
With CertuAIThe agent answers in seconds, qualifies and schedules the test drive before you open the store
TodayThe salesperson spends the morning answering whether the car in the ad is still available
With CertuAIThe agent answers availability and version on its own, and the salesperson gets people who already want to visit
TodayTest drive booked by phone and forgotten by the customer
With CertuAITime confirmed in the conversation, with a reminder the day before
TodayAnyone who did not reply in the first week disappears from the spreadsheet
With CertuAIAutomatic follow-up keeps the conversation alive and logged in the CRM
What does a conversation handled by the AI look like?
Example conversation
Dealership AI agent
Customer: Is the model from the ad still available?
AI agent: I'll check for you. Meanwhile: which version, when are you looking to buy and how do you plan to pay?
Customer: Can I do a test drive Saturday morning?
AI agent: On Saturday morning I have your open slots. I'll confirm with the right salesperson and car, and send you a reminder the day before.
Is an AI agent or manual customer service better for car dealerships?
The agent wins at repetitive tasks, and people keep winning at what takes judgment. With manual service someone at the dealership has to stop what they are doing; with the Certu Agent the answer goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Ad lead outside business hours | Waits for the team to arrive, and by then the customer has already talked to another dealer | Answered in seconds, qualified and with a visit scheduled |
| Asks whether the car in the ad is still available | Keeps the salesperson busy dozens of times a day | Answered on its own, with the inventory you keep updated |
| Test drive scheduling | Booked by phone, with no confirmation and no reminder | Confirmed in the conversation, with a reminder the day before |
| Lead record | Depends on the salesperson entering it in the spreadsheet after hours | Each conversation becomes a contact, a deal and a task in the CRM on its own |
| Lead idle for a week | Drops off the list and nobody follows up | Automatic follow-up, without depending on someone remembering |
What does the WhatsApp agent do for car dealerships?
It does the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers clients your way, with your rules.
Instant reply to ad leads
Whoever clicks the ad gets an answer in seconds, already about the model they asked about, at any hour.
Interest qualification
Model, version, purchase timeline and payment method, all logged before it reaches the salesperson.
Test drive scheduling
Time confirmed in the conversation, with the right salesperson and car, and a reminder the day before.
Qualified lead distribution
The deal opens in the CRM already with the responsible salesperson, by the rule of brand, vehicle type or the day's duty roster.
Follow-up with leads who did not come back
Someone who asked for terms and went quiet gets a new message about the same model, with no one having to remember.
What questions do clients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday dealership messages no longer depend on you having your phone in hand.
How does the agent start answering customers at the dealership?
In three steps, on the same day. No installation, no code and no changing the number clients already know.
Teach your business
In one conversation, you explain catalog, prices, delivery, warranty, and rules, the way you would to a new employee.
The agent answers
It answers right away, records each order and quote in the included CRM, and contacts again those who went quiet.
How much does a WhatsApp AI agent cost for car dealerships?
The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business Brain, the CRM, automatic follow-up and AI assistants, which come with every paid plan. Pro costs US$ 120 per month and adds the landing page, the wallet and 10 people on the team instead of 5. No contract and no setup fee.

Create the agent, connect WhatsApp and see it working at the dealership.
Create my agentWhat needs to be ready before turning on the agent at the dealership?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The list of models, versions and colors on the lot, separating new from used, and how often it is updated
- The terms published in the ads: minimum down payment, number of installments and what is already included in the advertised price
- The banks and lenders the dealership works with, and what the agent can say about credit without speaking for the bank
- The lead distribution rule: by brand, by vehicle type or by the day's duty roster
- The test drive schedule: how many fit per time slot, which cars are available and who accompanies the customer
- What the dealership accepts as a trade-in and the note that the appraisal of the used car is done in person
Whether the agent can repeat the financing terms from the ad or whether every installment conversation waits for the salesperson.
The most common mistake: Letting the agent confirm that a car is on the lot from last week's list. Someone who crosses the city for a specific version decides the trip based on that answer, and inventory is the part of the Brain that needs daily updating. Read how to fix this.
Frequently asked questions from car dealerships
Does the agent negotiate price and discounts with the customer?
No. It answers availability, version, options and the terms you publish, qualifies the interest and hands off to the salesperson. Negotiation stays with your team.
How does the qualified lead reach the right salesperson?
You define the distribution rule, by brand, by vehicle type or by the day's duty roster. The agent opens the deal in the CRM already with the responsible salesperson and an open task for them.
Can it separate interest in new cars from used cars?
Yes. The agent identifies the interest in the conversation and logs separate deals in the CRM, each with its responsible salesperson.
Does it answer questions about financing approval?
It logs that the customer asked and notifies whoever handles financing at the dealership. Credit status comes from the bank, so the agent does not give the answer in its place.
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
Ad leads go cold with a full showroom. The agent answers version and color, schedules the test drive and opens the deal in the CRM with the right salesperson.
