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 message asking the price of a perfume arrives in the middle of the night and goes unanswered
With CertuAIThe agent answers right away, with the price range you set
TodayGift kit arranged by phone and jotted down on a piece of paper at the register
With CertuAIThe kit order is written in the conversation, and the counter just checks and assembles it
TodayA customer asks about the shade of a foundation and nobody can stop to look
With CertuAIThe agent covers the line and hands the shade confirmation to the team
TodaySomeone who has bought before has to repeat their address and preferences every time
With CertuAIThe contact in the CRM keeps the history and the conversation starts out ahead
What does a conversation handled by the AI look like?
Example conversation
The shop's AI agent
Customer: Is this moisturizer good for oily skin?
AI agent: I can tell you how the brand positions this moisturizer: what you set up. I don't make recommendations for treating skin problems.
Customer: Can you still deliver today? Until what time can I order?
AI agent: Yes. In your area, the cutoff time is your time and shipping is your price.
Is an AI agent or manual customer service better for cosmetics 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 |
|---|---|---|
| Question about brand and price range | Answered when the store empties out, often the next day | Answered right away, with the lines you set up |
| Foundation shade or specific color | The customer goes to the store just to find out whether it exists | The agent explains the line and hands the shade confirmation to the team |
| Gift kit put together in a rush | Arranged by phone, with the items jotted down on paper at the register | Items, packaging cost and pickup date recorded in the conversation |
| Order to be delivered the same day | Accepted without anyone knowing whether today's delivery still fits | The agent answers with the delivery window and cutoff time you set |
| Customer who reorders the same product every month | Has to explain everything again with every order | The history stays on the CRM contact, and the conversation picks up where it left off |
What does the WhatsApp agent do for cosmetics 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.
Brands, lines and price range
The agent answers what the store sells and how much it costs, using what you keep in the Brain.
Gift kit assembly
Items, packaging cost, card and pickup date recorded before the order reaches you.
Same-day delivery window
Delivery area, shipping cost and the cutoff time to still receive it today, set the way you define it.
Skin recommendation limit
The agent describes what the product is and how the brand positions it, and does not recommend treatments for skin problems.
Terms for resellers
Minimum quantity, discount and payment terms, answered according to your rules.
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.

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 brands and lines the store sells, and the ones it doesn't carry
- The price range per line and what changes when the item comes in a sealed kit
- How the gift kit works: what goes in it, the packaging cost and how long it takes to assemble
- The delivery area, shipping cost, the day's delivery window and the cutoff time for an order to still go out today
- The exchange policy for opened cosmetics and sealed products
- Terms for resellers: minimum quantity, discount and payment terms
Whether the agent can suggest a shade or a line based on what the customer describes, or whether every question about color and texture goes to the team.
The most common mistake: Letting the agent recommend products for skin problems. Describing what the brand positions is one thing, saying what clears up acne is another, and the second doesn't belong in automated customer service. Read how to fix this.
Frequently asked questions from cosmetics stores
Does the agent check the store's inventory?
No. It works with what you taught it: brands, lines, price range, delivery and exchange policy. Specific shades and items that have to be seen on the shelf become an alert to your team.
Does it recommend products for skin problems?
No. It describes what the product is and what the brand positions it for. Skin questions stay with you and with the professional the customer sees.
Does it remember what the customer bought last time?
Yes. The contact in the CRM keeps the conversation history, so customers who reorder the same line every month don't have to start the explanation over.
Does it answer questions about original, sealed products?
It answers with the text you write about origin and seal. It's the question that comes up most for perfume, and it's worth having the answer come out the same 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
Answers questions about brands, builds gift kits and arranges delivery even in the middle of the night, and the CRM keeps the history of customers who always reorder the same line.
