What changes in the snack bar with an AI agent?
What changes is who answers first: the message no longer waits for you and gets an answer right away. These are four everyday situations at the snack bar before and after the CertuAI agent.
TodayTen messages piled up at the evening peak and nobody to answer
With CertuAIThe agent handles all ten at the same time, with no conversation queue
TodayCustomer asks the fee for their neighborhood and gives up waiting for an answer

TodayAddress written down wrong and the courier drives around the whole neighborhood
With CertuAIAddress written and checked in the conversation before dispatch
TodayQuestion about closing time repeated all night
With CertuAIAutomatic answer, even after the griddle is turned off
What does a conversation handled by the AI look like?
Example conversation
Snack bar AI agent
Customer: Can you take out the onions and put the sauce on the side?
AI agent: Yes. Noted: no onions and sauce on the side, each note on the right sandwich.
Customer: Do you deliver to the Santa Mônica neighborhood? What's the fee?
AI agent: Send me the street, number, unit and landmark and I'll check the fee and the time for the neighborhood.
Is an AI agent or manual customer service better for snack bars?
The agent wins at repeated tasks, and the person keeps winning at what takes judgment. With manual service someone at the snack bar has to stop what they are 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 |
|---|---|---|
| Order at the rush | Message goes unanswered and the customer orders somewhere else | The agent answers everyone at the same time and builds each order |
| Menu and combos | Photo of the menu resent in every conversation | Answered in text, item by item, with the right price |
| Fee and delivery time | Estimated off the top of the head, causes complaints later | Given in writing, with the neighborhood rule you set |
| Address and payment method | Jotted down in a rush, with a risk of error when the order goes out | Recorded in the conversation, checked before dispatch |
| Customer who always orders the same thing | Has to repeat the whole order every time | The history stays in the CRM and the agent picks up where it left off |
What does the WhatsApp agent do for snack bars?
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.
Menu, combos and extras
Sandwich, side, drink and the day's special, with the price of each extra listed separately, which is where the total usually goes wrong.
Order built with a note for each sandwich
No onions on the first, sauce on the side on the second: each note is tied to the right item, and not to a loose sentence at the end.
Real fee and time by neighborhood
The rule you set for each area, and the peak-time estimate, which is not the same as six p.m. on a Tuesday.
Address checked before dispatch
Street, number, unit and landmark written in the conversation, so the courier doesn't drive around the neighborhood looking for the right gate.
The usual, without repeating everything
The history stays on the contact, and someone who orders the same sandwich every Friday doesn't have to build the whole order again.
What questions do clients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday snack bar messages no longer depend on you having your phone in hand.
How does the agent start answering customers at the snack bar?
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 an AI agent on WhatsApp cost for snack bars?
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 in the snack bar.
Create my agentWhat needs to be ready before turning on the agent at the snack bar?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The full menu with prices, including each extra and what each combo includes
- The fee table by neighborhood and, above all, how far you don't deliver
- The average delivery time at quiet hours and at the peak, because it is not the same number
- The payment methods you really accept, including which meal voucher brands
- The possible customizations: what can be removed, what can be swapped and what is charged separately
- The order cutoff time for each day, including Sunday and holidays
Whether the agent closes the order and sends it straight to the kitchen or whether your team checks every order before starting to make it.
The most common mistake: Registering the fee by neighborhood and forgetting to say how far you don't deliver. The agent accepts an order from the other side of the city, and the customer only finds out when someone calls to cancel. Read how to fix this.
Frequently asked questions from snack bars
Does the agent deliver the order or call a courier?
No. CertuAI doesn't make deliveries or call a motorcycle courier. It builds the order, records the address and payment and hands that over ready to your team.
Does it connect to my point-of-sale system?
The order stays in writing in the conversation and becomes a contact and a deal in the CRM, which is included. Entering it into the point-of-sale system stays with your team.
Does it record extras and notes without mixing them up?
It records them per item. Each sandwich in the order carries its own extras and its own note, and the kitchen reads them already separated.
At the evening peak, does it answer everyone at the same time?
Yes. That is where messages sit the longest, and where a conversation with no answer in five minutes becomes an order placed with a competitor.
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.
