What is the best WhatsApp chatbot for shoe stores in Brazil?

The best WhatsApp chatbot for shoe stores in Brazil is the one that answers on the number the store already uses, with the business rules written by you. An AI agent on WhatsApp for a shoe store is CertuAI's automatic assistant.

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 if you have the model in their size and the message goes into the day's queue

With CertuAIThe agent answers the line and the price range right away and already tells the team to check the pair

What does a conversation handled by the AI look like?

Is an AI agent or manual customer service better for shoe 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.

AspectThe manual wayWith the CertuAI agent
Question about size and colorThe customer waits for someone to step away from the register to check the shelfThe agent answers the line and the price range right away, and passes on the pair check already written
Screenshot of a model seen on InstagramGoes unanswered until the store opens the next dayThe agent receives the photo, logs the model they are looking for and answers what it knows
Exchange policy for children's shoesEach salesperson quotes a slightly different deadlineAlways answered with the deadline and condition you wrote
Size missing from the size runThe customer leaves and nobody writes down what they were looking forModel and size stay on the contact, ready to call when the new shipment arrives
Hours, address and payment methodsAsked several times a day, always between one customer and the nextAnswered at any hour, including outside business hours

What does the WhatsApp agent do for shoe 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 usual size range

The agent says what the store carries and up to what size each line usually goes, based on what you keep in the Brain.

Pair check request

Model, color and size reach your team in writing, so whoever checks the shelf doesn't need to reopen the conversation.

Exchange, deadline and receipt requirement

How many days, what the store takes back and what changes for children's shoes, the way you write it.

Payment and installments

Card, Pix (Brazil's instant payment) and number of installments given before the customer crosses town.

Waitlist by size

Anyone who looked for a size that was out of stock is saved in the CRM, ready to be contacted when the new shipment arrives.

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.

Do you have these sneakers in a 38? Is a new shipment of this model coming in? Can you let me know? How much is the model in the photo? If it doesn't fit my son, can I exchange it without the receipt? How many installments do you offer? Do you deliver to my neighborhood?

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.

1

Teach your business

In one conversation, you explain catalog, prices, delivery, warranty, and rules, the way you would to a new employee.

2

Connect WhatsApp

Scan a QR code with the number your clients already know. Ready in minutes.

3

The agent answers

It answers right away, records each order and quote in the included CRM, and contacts again those who went quiet.

How much does an AI agent on WhatsApp cost for shoe stores?

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. Pro costs US$ 120 per month and adds the landing page, the wallet and 10 people on the team instead of 5. No contract and no setup fee.

What 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 carries, and up to what size each one's size run usually goes
  • The price range per line, separating what is on sale from list price
  • The exchange policy: deadline, whether a receipt (nota fiscal) is required and what changes for children's shoes
  • Payment methods, number of installments and whether Pix (Brazil's instant payment) is priced differently
  • Address, opening hours and whether the store delivers in the neighborhood, with fee and lead time
  • Who receives the pair check request, and at what time that person can look at the shelf

Whether the agent can say that a size usually exists in the store, or every size question turns into a check with the team.

The most common mistake: Writing the size run in the Brain once and never touching it again. Sizes are the data that changes the most in a shoe store, and a size run from six months ago makes the agent confirm a size the store no longer carries. Read how to fix this.

Frequently asked questions from shoe stores

Does the agent see my inventory in real time?

No. CertuAI doesn't read inventory, and in footwear the data that changes fastest is the size run. The agent answers brands, price range and up to what size each line usually goes, and sends the pair check to your team already written.

What if the customer sends a photo of a model?

It receives the photo in the conversation, logs the model and the size the person is looking for and passes it to your team to confirm.

Can I contact people who were looking for a size that was out of stock?

Yes, and you are the one who contacts them. The conversation stays in the contact's history in the CRM, with the model and the size the person asked for, so when the new shipment comes in you know who to go back to. The agent doesn't send that notice on its own.

Does it explain the size differences between brands?

It answers what you write in the Brain. If the store knows that a brand runs small, it is worth writing that down, because it is the information that prevents the most exchanges later.

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.

In short

Answers brand, size range, exchanges and installments right away, and the CRM keeps the model and size each customer came looking for in the store.
