What does a conversation handled by the AI look like?
Example conversation
Pastry shop AI agent
Customer: Do you make a hundred pastries for a party? How much notice do you need?
AI agent: We do. Tell me the flavors, the quantity, the date and the time. Do you want them fried on the spot or to fry at home?
Customer: Which market are you at today?
AI agent: Today the stall is set up at what you registered.
Is an AI agent or manual customer service better for pastry shops?
The agent wins at repeated tasks, and the person keeps winning at what takes judgment. With manual service someone at the pastry shop 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.

|---|---|---|
| List of flavors and prices | Typed again for every customer, in the middle of the rush | Answered right away, with the menu you maintain |
| Order of a hundred for a party | Kept in someone's head and checked only the day before | Recorded with flavors, quantity, pickup date and time |
| Which market the stall is at today | Answered one by one, when there is time | The agent gives the day's spot that you set |
| Neighborhood delivery order | Depends on someone leaving the fryer to answer | Built in writing in the conversation, ready for your team to dispatch |

What does the WhatsApp agent do for pastry 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.
Menu of savory pastries, sweets and sugarcane juice
Each item with its unit price and its portion price, the way you sell at the stall and not in a generic table.
Order of a hundred with a pickup time
Flavors, quantity, date and time recorded in writing, and the difference between delivering fried on the spot and delivering to be fried at home.
The market or spot where the stall is today
You set where the stall is set up and the agent answers, instead of the customer going to the wrong market on a Saturday morning.
Neighborhood delivery order
Items, address and payment written in the conversation, ready for your team to head out, without anyone leaving the oil to take notes.
How many hundreds fit in the fryer today
The agent knows your production limit and turns down a date that doesn't fit, offering the next one that works.
What questions do clients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday pastry shop messages no longer depend on you having your phone in hand.
How does the agent start answering customers at the pastry 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.
How much does an AI agent on WhatsApp cost for pastry shops?
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 my agentWhat needs to be ready before turning on the agent at the pastry shop?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The full menu with unit prices, including sweet pastries, portions and sugarcane juice
- The week's schedule of markets and spots, with address and setup time
- The price of a hundred by flavor and the difference between delivering fried on the spot and delivering to be fried at home
- How many hundreds the fryer can handle per day and how many hours ahead you need notice
- The delivery area and the fee by neighborhood, if you deliver
- The deposit rule for big orders
Whether the agent closes the order of a hundred on its own or whether every order above a certain size goes through you first.
The most common mistake: Registering the hundred at a single price. Pastries fried on the spot and pastries to fry at home cost different amounts and take different work, and the customer who agreed to one arrives expecting the other. Read how to fix this.
Frequently asked questions from pastry shops
Does the agent know which market we are at today?
It knows what you set in the Brain. You update the day's spot from your phone and it starts answering that way.
Does it say whether the hundred goes fried or to be fried at home?
It does, and it is worth registering them as two products with different prices. It is the most common misunderstanding here, and it shows up on the day of the party.
Does it work for big orders, a hundred or more?
Yes. It records flavors, quantity and time, and warns if the requested lead time is too short for what you can fry.
Can it answer while the stall is closed?
Yes, and that is when orders tend to come in. Someone messages on Thursday night for a Sunday party and leaves the conversation with a confirmed date.
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.
