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.
TodayA customer asks how many liters they need and waits for someone to step away from the tinting machine
With CertuAIThe agent estimates it right away from the coverage and coats you set up
TodayThe difference between flat and semi-gloss explained ten times a day
With CertuAIAutomatic answer, always with the text you wrote
TodayAn urgent job-site order arrives by voice message and the address comes out wrong
With CertuAIThe delivery driver leaves with the address, landmark and items checked in writing
TodayA painter who buys every week has to repeat everything on each order
With CertuAIContact in the CRM with history, and the order starts out already half done
What does a conversation handled by the AI look like?
Example conversation
The shop's AI agent
Customer: How many liters do I need to paint a four-by-three wall?
AI agent: Based on the area you gave, the coverage per liter and the number of coats, the estimate is what you added.
Customer: Can you deliver today? The painter is already at the job site
AI agent: Send me the items, the address, a landmark and the time. It all goes in writing for the delivery driver.
Is an AI agent or manual customer service better for paint 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 |
|---|---|---|
| How many liters for a given area | The customer waits for someone to step away from the tinting machine to do the math | The agent estimates it from the coverage and coats you added |
| Difference between finishes | Explained ten times a day, in different words each time | Always answered with the text you wrote |
| Color in the tinting system | Can only be settled with the customer in the store | The agent explains how it works and passes the base confirmation to the team |
| Urgent delivery to the job site | Address dictated by voice message, with the risk of the driver circling around looking for it | Address, landmark, time and items recorded in writing |
| Painter who buys every week | Repeats the same conversation and the same terms on every order | The history stays on the CRM contact and the order starts half done |

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.

From the coverage per liter and the number of coats you add, with the area the customer gives.
Explanation of finish and line
Flat, satin, semi-gloss and enamel, the way you describe them in the Brain.
How tinting works
Which bases the store carries, what is ready on the spot, and what needs a check from the team.

Items, address, landmark and time recorded in writing, ready for the delivery driver.
Painter and contractor accounts
The terms for someone who always buys, with the history saved on the contact in the CRM.
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, records each order and quote in the included CRM, and contacts again those who went quiet.

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.

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 coverage per liter of each line, as the manufacturer states it, and how many coats the store recommends
- The price table by container size: can, gallon and bucket, by line
- The explanation of each finish written your way: flat, satin, semi-gloss and enamel
- How tinting works at the store, which bases exist and what is not ready on the spot
- The delivery area, the shipping cost and the cutoff time for paint to reach the job site today
- The painter and contractor terms, and what you require before granting payment terms
Whether the agent can close the order with the quantity it estimated itself, or whether your team confirms the number before picking.
The most common mistake: Adding coverage without saying how many coats. A calculation made with one coat sends the painter back to the store in the middle of the job, and the estimate turns into a complaint instead of a sale. Read how to fix this.
Frequently asked questions from paint stores
Does the agent check whether the paint and base are in stock?
No. CertuAI does not read inventory, and with paint, what holds things up is the tinting base. It answers about lines, finishes, coverage and price range, and passes the base and color confirmation to your team.
Is the quantity calculation reliable?
It uses the coverage per liter and the number of coats you add, with the area the customer gives. It is an estimate to guide the order, and your team confirms it at the time of sale.
Does it say which paint to use on each surface?
It answers what you write about each line, such as floors, exteriors and wood. Where the store usually asks for a look at the site, the agent hands it off instead of taking a risk.
Does it work for a store that sells a lot to painters and contractors?
Yes. The contact is saved in the CRM with the order history and the agreed terms, so someone who buys every week doesn't have to repeat everything.
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
Calculates the amount from the coverage and number of coats you added, explains the finishes, and records the job-site delivery address in the CRM.
