The 5 options, one by one
-
1. When to use WhatsApp Business?
Free, on Google Play and the App Store.
- What it is
- Use WhatsApp Business when you are just starting out or want to separate the company's number from your personal one. Strengths: it is Meta's free app, with catalog, cart, labels, quick replies and greeting and away messages.
- Who it is for
- Use it when: you answer the messages yourself and can still keep up with the volume.
- Where it falls short
- Weaknesses: you are the one who answers, and the away message is always the same text. Meta Business Agent, Meta's AI inside the app, is available to qualified businesses in selected markets.

2. When to use Nuvemshop?
Começo free, with 4.69% per sale on Nuvem Pago, or Essencial at R$ 69 per month. Nuvem Chat, an assistant on WhatsApp, costs R$ 1.50 per conversation on Começo.
- What it is
- Use Nuvemshop when you want an online store where the customer chooses and pays without needing to chat. Strengths: a free plan with no time limit, with its own payment and shipping.
- Who it is for
- Use it when: you sell products at a fixed price and want the customer to buy on their own.
- Where it falls short
- Weaknesses: the store doesn't answer whoever messages on WhatsApp, and Nuvem Chat, charged per conversation, goes up in cost with traffic. Those who sell services get less out of the storefront.

3. When to use Mercado Pago?
No monthly fee. Payment link: Pix (Brazil's instant payment) 0.99%, card 4.98% to receive right away or 3.99% in 30 days, boleto (bank slip) 3.99%.
- What it is
- Use Mercado Pago when the sale closed in the conversation and you just need to charge: you send a payment link on WhatsApp. Strengths: no subscription, card in up to 18 installments, Pix (Brazil's instant payment) and boleto (bank slip).
- Who it is for
- Use it when: you already close the sale in the conversation and only need to get paid.
- Where it falls short
- Weaknesses: it doesn't talk to anyone. Someone needs to answer questions and send the link at the right time. Offering the buyer interest-free installments adds a fee for you.

4. When to use RD Station CRM?
Free plan, up to 4 users. Basic R$ 65.70 per user per month on the annual plan, with an AI copilot.
- What it is
- Use RD Station CRM when more than one person sells and nobody knows who talked to whom. Strengths: the Free plan has a sales pipeline, task reminders and a CRM next to WhatsApp Web.
- Who it is for
- Use it when: two or more people sell and you want to see each negotiation in a pipeline.
- Where it falls short
- Weaknesses: it organizes, but doesn't answer the customer. Someone still types each reply, and the AI copilot only comes with Basic, charged per user.

5. When to use CertuAI?
Start US$ 75 per month, with the AI, 1,600 replies and 5 people. No lock-in.
- What it is
- Use CertuAI when messages arrive faster than you can answer, or while the store is closed. The AI answers on the number you already use, with the price, the deadline and the way of paying that you taught it. Strengths: it answers right away, notes down each customer in the CRM on its own and follows up with people who went quiet.
- Who it is for
- Use it when: you lose sales to delays and want to keep the catalog, the store and the way of charging that you already have.
- Where it falls short
- Weaknesses: if you get few messages and answer all of them the same day, free WhatsApp Business is enough. CertuAI is also not an online store or a payment method.

How CertuAI built this list
Four well-known brands, one for each stage of the sale: chatting, showing, charging and organizing. CertuAI comes last because it works alongside the others, not in place of them. Prices read on each company's official page on Sep 25, 2026. Nobody paid to appear here.
Is CertuAI worth paying for if WhatsApp Business is free?
It depends on how many messages go unanswered. Many customer messages arrive outside business hours. That is when, without AI, the customer only gets the away message.
Start costs US$ 75 per month for 1,600 replies: less than US$ 0.05 each. If the sales that come in while the store is closed add up to more than US$ 75 in the month, the AI pays for itself.
How do you combine the tools to sell more?
1. Show what you sell in the WhatsApp Business catalog.
2. Open the store on Nuvemshop for those who want to buy on their own.
3. Charge with the Mercado Pago link.
4. If more than one person sells, track everything in RD Station CRM.
5. When messages go beyond what you can handle, turn on CertuAI on the same number to answer right away, day and night.
