What does a conversation handled by the AI look like?
Example conversation
Company AI agent
Customer: How much does it cost to renovate a sixty-square-meter apartment?
AI agent: Tell me what you want to renovate, the desired timeline and the investment range. I'll put together the summary for the team.
Customer: Can you do a visit to quote, with no commitment?
AI agent: Yes. I have your free time slots for a visit at the job site address.
Is an AI agent or manual service worth more for renovation companies?
The agent wins at repetitive tasks, and people keep winning at what takes judgment. With manual service, someone at the company has to stop what they're 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 |
|---|---|---|
| Price question with no briefing | The conversation stalls on "it depends" and the customer looks for another company | The agent pulls scope, square footage and timeline before any price |
| Booking the site visit | Arranged over the phone in the middle of a job and forgotten during the week | Booked on the team's calendar, with confirmation the day before |
| Telling the curious from a real project | Only becomes clear after you have already traveled to the address | The briefing shows scope and budget before the team heads out |
| Condo building renovation rules | Repeated in every conversation: permitted hours, authorization, dumpster | Answered on its own, with what you wrote once |
| Proposal sent with no reply | Waits for the customer to remember to reply | The agent picks the negotiation back up a few days later |
What does the WhatsApp agent do for renovation companies?
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.
Renovation briefing
Asks what the customer wants to renovate, approximate square footage, desired timeline and investment range, and hands you the finished summary.
Technical visit booking
Shows the free days in your calendar and books the visit at the job site address, without endless back-and-forth messages.
Answers about how you work
Regions you serve, payment methods, whether you issue a nota fiscal (Brazilian tax invoice) and how the project schedule works, all defined by you.
Screening for what is worth your time
Separates people who just want a ballpark figure from people with a real project, so you can prioritize the right visits.
Quote follow-up
After the proposal is sent, the agent picks the conversation back up at the right time and reopens the negotiation.
What questions do clients send on WhatsApp?
They're always the same questions, and the agent answers each one on its own. These everyday company messages no longer depend on you having your phone in hand.
How does the agent start answering customers at the company?
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 services, prices, hours and rules, as you would to a new employee.
How much does a WhatsApp AI agent cost for renovation companies?
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 the agent, connect WhatsApp and see it working at your company.
Create my agentWhat needs to be ready before turning the agent on at the company?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The types of work you take and the ones you turn down, such as structural work or a renovation without a plan
- Whether the price covers only labor or materials too, and who buys the tile and finishes
- Whether you carry out an architect's plan or do your own drawing before starting
- Condo building renovation rules: permitted hours, the building manager's authorization and who hires the dumpster
- Whether the site visit is charged and whether the fee is deducted when the job is signed
- The investment range above which it is worth sending the team out
Whether the agent gives a per-square-meter range for standard-priced services, such as painting and tile setting, or whether every price comes only after the visit.
The most common mistake: Letting the agent talk about the project timeline before the visit. A wall with hidden moisture or an old electrical panel changes the entire schedule, and the timeline said on WhatsApp is the first one the customer holds you to at handover. Read how to solve this.
Frequently asked questions from renovation companies
Does the agent give the renovation price over WhatsApp?
A serious renovation depends on a site visit, and the agent explains exactly that. It gathers the briefing and turns the inquiry into a booked visit instead of guessing a price.
How does it help avoid wasting time on people just curious?
By doing the briefing before you go. Someone who just wants a loose number becomes clear in the conversation, and you save your visits for real projects.
Can I change what it says about the company?
Yes. You teach it the regions, payment methods and how you work once, and adjust whenever you want.
Does it work outside business hours?
That is when it works the most. Late in the afternoon and on weekends the customer gets an answer right away and the visit calendar is filled by morning.
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
Briefing on scope, square footage and timeline before any price, a site visit booked on the team's calendar and the proposal tracked closely in the CRM.
