How to Sell on WhatsApp Business Step by Step: Strategies, Templates and Phrases (2026)

In Colombia, WhatsApp is the number one sales channel for thousands of businesses. The question is no longer whether to sell on WhatsApp, but how to sell more without spending the day glued to your phone. Here's the step-by-step process, message templates ready to copy and a checklist to review your strategy.

#How to sell on WhatsApp Business, step by step

1. Install WhatsApp Business (it's free) with a number dedicated to the business.
2. Complete your profile: logo, a clear description, opening hours, address and a link to your website.
3. Create your catalog with real photos, price and a short description of each product.
4. Set up automatic messages: greeting, away message outside business hours and quick replies.
5. Organize with labels: "new", "quoted", "paid", "shipped".
6. Drive traffic: a WhatsApp button on your website, Meta ads that open the chat and a link on Instagram.
7. Close with a payment link (Wompi, Bold, PayU or bank transfer) instead of waiting for the customer to "let you know".
8. Follow up with anyone who hasn't replied within 24 hours, without overdoing it.

#Message templates for selling on WhatsApp

Copy, adjust and save them as quick replies:

• Greeting: "Hi, [name]! 👋 Thanks for writing to [business]. What are you looking for today? I'll help you in a moment."
• Sending a product: "Here's the [product] I mentioned: [price]. We have it in [sizes/colors]. Which one do you prefer?"
• Answering questions: "Sure. Shipping to [city] takes [days] and costs [amount]. If you pay today, it ships tomorrow."
• Closing: "Here's the secure payment link: [link]. As soon as it's confirmed, I'll send you the tracking number."
• Follow-up: "Hi, [name]. Did you get a chance to look at the [product]? I can hold it for you until tomorrow if you'd like."
• After the sale: "Your order arrived! What did you think? If you leave us a review, we'll give you [benefit] on your next purchase."

#Mistakes that cost you sales

• Replying hours later: most customers buy from whoever answers first.
• Sending long voice notes or price lists in PDF without context.
• Asking the customer to "write when you want to pay" instead of sending the link.
• Sending bulk messages from the regular app: WhatsApp may ban your number.
• Not saving customer details to sell to them again.

#When the app can't keep up: API + AI

If you get dozens of messages a day, the app falls short. The official WhatsApp Business API lets you:

• Have several reps on the same number.
• Run an AI agent that replies 24/7 with your real prices and inventory.
• Collect payment inside the chat and issue the electronic invoice automatically.
• Send permitted bulk messages with templates approved by Meta (with a per-message cost by category).
