How to sell on WhatsApp in 2026: a step-by-step guide for your business

The WhatsApp Business app is free and works well when one person replies from their phone. The official API (Meta's WhatsApp Business Platform) lets several people answer the same number from a shared inbox, connect a CRM and an AI assistant, and send templates to customers who agreed to receive your messages.

It isn't a one-way door: with WhatsApp coexistence you connect your number to the API and keep using the app on your phone. If you're unsure, read whether you can use the app and the API together.

Every place a customer finds you should have a shortcut to your WhatsApp:

• A wa.me link with a pre-filled message for your bio, emails and ads. Create one with the WhatsApp link generator.
• A QR code in your store, on packaging, cards and flyers, with the QR code generator.
• A WhatsApp button on your website, with the button generator.
• Click-to-WhatsApp ads on Facebook and Instagram: reply within the first 24 hours and the conversation stays free for 72 hours.

People who message on WhatsApp are often comparing options at the same time. Three habits help you reply fast without losing quality:

• Saved replies for prices, opening hours, shipping and payment methods.
• An AI assistant that answers 24/7 from your business information and hands the chat to a person when it's time to close. See what an AI assistant can do on WhatsApp.
• A shared inbox where every chat is assigned to someone, so none goes unanswered. Read how several agents can answer one number.

Since October 1, 2026 every message you send inside the 24-hour window is billed, so answer with complete messages instead of several short ones.

A chat without a stage is a sale nobody is following. Define a few clear stages, for example New → Interested → Quoted → Won or Lost, and move each customer when their situation changes. Use tags for product, source (ad, QR, website) and priority, so anyone on the team knows what comes next. More in WhatsApp sales pipelines.

Outside the 24-hour window you can only message a customer with a Meta-approved template, and only if they agreed to receive your messages. Utility templates cover order, appointment or payment updates; marketing templates cover offers and purchase reminders. In Mexico, from October 1, 2026, a utility template costs US$0.0085 and a marketing template US$0.0397.

Get ideas from our WhatsApp template library, check why Meta rejects templates and, before messaging many contacts, read how to send bulk WhatsApp messages safely.

Each week, check four numbers: how many new chats came in and from where, how long the first reply took, how many chats reached Won, and how much each person sold. That tells you which channel to grow, who needs support and which replies to improve.

• Bulk messages to people who didn't opt in. Meta can limit or block your number and lower its quality rating.
• Several people on one phone. Nobody knows who replied or what was promised.
• No follow-up. Many customers don't buy in the first chat; without a reminder, the sale goes cold.
• Bots with long menus. They tire customers and, since October 1, 2026, every extra message also costs money.

ChatSales connects your number to the official WhatsApp API, with coexistence so you can keep using the app. Your team works from a shared inbox, every chat moves through your pipeline, the AI assistant answers 24/7 from your information and people close the sales. You pay for messages directly to Meta, with no markup.
