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: What sizes and prices do you have?
AI agent: The sizes and prices are your price. Want to add granola, fruit or powdered milk?
Customer: Do you deliver to my neighborhood? What's the fee?
AI agent: Send me the address and a landmark and I'll tell you the fee and the delivery time.
Is an AI agent or manual service better for açaí shops?
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 |
|---|---|---|
| Order at the afternoon peak | Waits for someone to step away from the counter and sometimes the customer gives up first | Taken right away, with the items confirmed one by one |
| Bigger cup and add-ons | Only offered when someone remembers in the middle of the line | Offered on every order, the way you defined |
| Delivery details | Asked one by one, stretching the conversation and the delivery | Collected along with the order: address, landmark and payment |
| Delivery fee and time by neighborhood | Answered from memory, with a different price from each attendant | Always answered the same way, from the table you maintain |
| A cream or fruit that ran out midday | Discovered by the customer only when the cup is being assembled | The agent stops offering it as soon as you update the menu |
What does the WhatsApp agent do for açaí shops?
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.
Order taking
Receives the order on WhatsApp, confirms the items and organizes everything so your team can assemble it without mistakes.
Sizes and add-ons
Offers the bigger cup and the add-ons you define, powdered milk, granola, fruit and creams, raising the average ticket on every order.
Delivery details
Collects the address, landmark and payment method, and gives the delivery fee and time for the area.
Menu and prices
Answers about sizes, flavors, add-ons and prices, all defined by you and updated whenever you want.
Hours and availability
Gives the opening hours and warns when something on the menu has run out, so the customer doesn't order what you don't have.
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 services, prices, hours and rules, as you would to a new employee.

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.

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 menu with cup sizes, creams, fruit and add-ons, each with its price
- Neighborhoods you deliver to, the fee for each and the minimum order value
- How far it is worth delivering without the açaí arriving melted
- Payment methods on delivery and whether the card machine goes with the motorcycle courier
- Opening hours and the cutoff time for accepting delivery orders
Whether the agent closes the delivery order on its own or sends the summary to someone to check before the team assembles it.
The most common mistake: Leaving the menu untouched when a cream or fruit runs out. The agent answers what is written, and updating the list in the middle of the afternoon is what keeps the promise it makes on every order. Read how to fix this.
Açaí shop FAQ
Does the agent raise the order value?
Yes. It offers the bigger cup and the add-ons on every order, the way you configure it, without depending on your team remembering in the rush of the line.
Can it handle the afternoon peak?
It can. Answering many people at once is exactly what the agent does better than a busy attendant at the counter.
Can I update the menu and add-ons?
Yes. You teach it the menu once and update it whenever you want: sizes, flavors, add-ons and prices.
Does it stop offering what ran out?
It does, as soon as you take the item off the menu. The agent answers exactly what is written, so what leaves the list in the middle of the afternoon stops showing up in the add-on suggestions.
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.
