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.
TodayThe list arrives as "ten circuit breakers and cable," and the salesperson spends the morning asking for the rest
With CertuAIThe agent asks for amperage, poles, gauge, color and length before the list reaches the counter
TodayA homeowner asks what wire to use for the shower and gets a guess by message
With CertuAIThe agent explains that it does not size installations, notes the appliance's power rating and brings in the salesperson
TodayAn electrician asks if you have his usual brand and gets no answer until lunch
With CertuAIAnswered right away, with the brands you keep registered
TodayA quote for a full panel sent on Monday and forgotten by Friday
With CertuAIDeal opened in the CRM and automatic follow-up with the customer who did not reply
What does a conversation handled by the AI look like?
Example conversation
The shop's AI agent
Customer: Do you sell 2.5 mm flexible cable by the meter or only the full roll?
AI agent: The store's cable cutting rule is what you registered. What gauge, color and length do you need?
Customer: Do you issue invoices to the construction company's CNPJ (business tax ID)?
AI agent: Yes, we issue the invoice to a CNPJ. I'll record the quote and pass it to the salesperson.
Is an AI agent or manual service better for electrical supply 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 |
|---|---|---|
| Materials list written halfway | The salesperson asks for gauge, color and length, one item per message | The agent asks for everything missing at once and returns the complete list |
| Question about whether the store sells cable by the meter | Answered when someone steps away from the counter | Answered right away, with the cutting rule and sealed roll rule you wrote |
| Customer asking which circuit breaker suits the shower | Turns into a guess by message, without seeing the panel or the installation | The agent does not size: it collects the appliance data and passes it to the salesperson |
| Requested brand the store does not carry | The customer only finds out at the counter | The agent gives the brands you registered for that item |
| Job quote sent and unanswered | Disappears in the week's list of conversations | Stays in the CRM as an open deal, with automatic follow-up |
What does the WhatsApp agent do for electrical supply 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 customers and electricians your way, with your rules.
The electrician's list, item by item
Receives the list, spots what is incomplete and asks for gauge, color, length, amperage, poles and brand before passing it on.
What the store carries
The cable, circuit breaker, outlet, conduit, panel and lighting lines and brands you registered, and what only comes by special order.
Sales by the meter, by the roll and by the sealed box
The rule for cutting cable, selling conduit by the length and selling sealed boxes, answered the same way for everyone.
Technical referral
Questions about which cable, which circuit breaker or which protection to use are not answered: the agent collects the power, voltage and distance the customer can provide and passes it to the salesperson.
What questions do customers and electricians 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 that customers and electricians already know.
Teach your business
In one conversation, you explain catalog, prices, delivery, warranty, and rules, the way you would to a new employee.
Connect WhatsApp
Scan a QR code with the number your customers and electricians already know. Ready in minutes.
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 an AI agent on WhatsApp cost for electrical supply stores?
The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business's Brain, the CRM, automatic follow-up and the 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 lock-in contract and no setup fee.

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 and brands the store carries by category: cable, circuit breaker, outlet and switch, conduit, panel and lighting
- The rule for selling by the meter, by the roll, by the length and by the sealed box
- What each item on the list needs to include so it can be quoted: gauge and color of the cable, amperage and poles of the circuit breaker, line and color of the outlet
- Who technical questions go to, what hours that person answers and what the agent says in the meantime
- Exchange rule, factory warranty, invoice to a CNPJ (business tax ID) and delivery to the job site
Whether the agent gives the price of fast-moving items from the table you maintain or whether every quote goes through the salesperson.
The most common mistake: Registering a table of "appliance X uses cable Y" to speed things up. The agent will apply the table without seeing the installation, and a wrong answer here overheats the wire inside the wall. Write that sizing is always done with a person.
Frequently asked questions from electrical supply stores
Does the agent say which cable or circuit breaker to use for an installation?
No. Sizing depends on the load, the distance, the panel and the code, and it is a matter for the electrician or the technical salesperson. The agent collects what the customer can provide and passes the conversation to a person.
Does it check stock in the store's system?
No. It answers from what you wrote and keep updated in the Brain. For fast-moving items that works. For large quantities or special-order items it records the request and leaves confirmation to the counter.
Can it serve electricians and first-time customers in the same way?
Yes, and the difference shows in the conversation. The electrician sends the list and gets the right questions to complete it. Someone who does not know what they need is referred to the salesperson, instead of getting a guessed list.
Does it handle exchanges for defective products?
It states the exchange and warranty rule you wrote, asks for the invoice and a description of the problem, and records the case. The decision to exchange stays with the store.
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
Circuit breakers, cable by the meter and the electrician's list answered from the store's catalog. Sizing goes to the salesperson and the quote stays in the CRM.
