What is the best WhatsApp chatbot for PPE stores in Brazil?
The best WhatsApp chatbot for PPE 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 PPE (personal protective equipment) store is an automatic assistant that answers what the CA (Certificate of Approval) number is for each item on file, which sizes exist, whether the store sells to individuals, the invoicing terms for companies (CNPJ) and the delivery time, building the order list in the conversation.

What does a conversation handled by the AI look like?
Example conversation
The shop's AI agent
Customer: What's the CA for this safety boot?
AI agent: The CA for this boot is what you entered.
Customer: Do you deliver straight to the construction site?
AI agent: Send me the area and the site address and I'll tell you the lead time.
Is an AI agent or manual customer service better for PPE 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 an item's CA | Someone looks it up on the product sheet and answers later | Answered right away, with the CA you entered on the item |
| Long order list | The salesperson retypes it item by item | The agent organizes the list with item, size and quantity in the conversation |
| Boot sizes available | Depends on someone checking the stock | Answered according to what you keep on file |
| Individual customer | Finds out at the end that the store only sells to companies | Gets the rule right away, in your words |
| Formal quote request | Waits in the queue until the salesperson opens the spreadsheet | The agent builds the list and opens the task for the salesperson to issue the quote |

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.
- A catalog by category with the CA number of each item
- The sizes the store really keeps in stock
- Whether the store sells to individuals and what the minimum order is in each case
- Invoicing terms for companies (CNPJ), including payment terms and what the company needs to send
- Delivery areas, lead time and the rule for delivery to a construction site
Whether the agent gives prices in the conversation or builds the list and the price comes in the salesperson's quote.
The most common mistake: Letting the agent talk about CA validity. The number is product data and can be answered, but validity changes and isn't in the Brain. Write in the Brain that this confirmation always comes from the store.
PPE store FAQ
Does the agent answer the CA for any product?
It answers the CA you entered on the item. For a product with no CA on file it doesn't make one up: it passes the question to your team to confirm.
Does it say whether the CA is valid today?
No. CA validity changes over time and CertuAI doesn't check the official database. The agent gives the number on file and checking validity stays with the store.
Does it check stock in real time?
No. It answers with what you keep on file in the Brain. When an item is critical, you set it to confirm with the store before closing.
Does it help with company orders that need a purchase order?
Yes. The agent organizes the list with item, size and quantity, and opens the task in the CRM for the salesperson to issue the quote in the format the company requires.
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 CA numbers, sizes and availability and organizes the company's order list. Every conversation becomes a contact and a task in the CRM, with nobody typing.
