What changes in the shop 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 shop situations before and after the CertuAI agent.

What does a conversation handled by the AI look like?
Example conversation
The shop's AI agent
Customer: My computer won't turn on, can you look at it today?
AI agent: That goes to the technician. Send me the model, the system and what you've already tried.
AI agent: With that, I'll forward the case ready to go.
Is an AI agent or manual customer service better for computer stores?
The agent wins on repeated tasks, and the person keeps winning on anything that takes judgment. With manual service, someone at the shop has to stop what they are doing; with the CertuAI agent, the reply goes out on its own and you step into the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Sales and repairs on the same number | People who want to buy and people whose machine is down compete for the same queue | The agent identifies the path in the first message and sends each person to the right place |
| Part compatibility question | The technician stops the repair midway to answer | The agent collects model, system and configuration and hands the technician a ready case |
| Quote for a machine or a custom build | Messages going back and forth all day | Price range and options answered right away, with what you set up |
| Warranty period and what voids it | Explained case by case, with different answers from each attendant | Always answered with the same rule you wrote |
| Sale to a company with an invoice | Depends on someone in administration being free | The agent collects the CNPJ, items and billing details and passes them to your finance team |
What does the WhatsApp agent do for computer stores?
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.
Triage between sales and repairs
People who want to buy go down the sales path; people with a machine that's down go to your technician.
Price range for machines and parts
Laptops, desktops, monitors and peripherals, with the prices you keep in the Brain.
Collecting data for the technical case
Model, system, configuration and what has already been tried, collected before it reaches your technician.
Service price list with price and turnaround time
Formatting, cleaning, screen replacement and data recovery, the way you set them up.
Business orders with an invoice
CNPJ (Brazilian company tax ID), items and billing details collected and forwarded to your finance team.
What questions do clients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday shop messages no longer depend on you having your phone in hand.
How does the agent start answering at the shop?
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, logs every request and quote in the included CRM and follows up with people who went quiet.
How much does a WhatsApp AI agent cost for computer stores?
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.
Get started now
Create the agent and connect WhatsApp to see it working in the shop.
Create my agentWhat needs to be ready before turning the agent on in the store?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The lines the store sells and the brands it doesn't service
- The service price list with price and turnaround: formatting, cleaning, screen replacement, data recovery
- The price range for each category of machine and peripheral
- The warranty for each line, what it covers and what voids it
- The data the agent needs to collect before passing a case to the technician: model, system and configuration
- Whether the store issues invoices to companies and what finance needs to receive for that
Whether the agent answers compatibility questions using what's written in the Brain or whether every technical question goes straight to the technician.
The most common mistake: Leaving sales and repairs on the same reply path. Someone who wants to buy a laptop and someone whose machine is down need different conversations, and mixing them delays both. Read how to fix this.
Frequently asked questions from computer stores
Does the agent check whether a part is in stock?
No. CertuAI doesn't read inventory. It answers lines, price range, warranty and the service price list you set up, and alerts your team when the question is about a specific item on the shelf.
Does it answer technical compatibility questions?
It answers what you taught it and collects model, system and configuration. The technical opinion stays with your team, which receives the case already detailed.
Can it separate over-the-counter sales from technical repairs?
Yes, and it's the main gain here. You define in the Brain what counts as a sale and what counts as a service, and the agent sends each conversation down the right path in the very first reply.
Does it explain what voids the warranty?
Yes, with the text you write. A broken seal, liquid damage and use outside the specifications are the three questions that come up most, and it's worth having them answered the same way every time.
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
Separates sales from repairs, answers price range and warranty questions, and hands over the technical case already detailed, with everything logged in the store's CRM.
