Selling on WhatsApp: the complete guide for businesses

Why sell on WhatsApp instead of email?

WhatsApp is the most direct channel you have to reach your customers: a message there gets read far more often than an email, and usually within minutes of being sent. Open rates on instant messaging apps are much higher than on email, where a large share of messages lands in spam or simply gets ignored. For a shop or a small business, the difference is tangible: a question asked on WhatsApp expects a fast answer, and a fast answer converts into a sale far more easily.

There is another advantage: WhatsApp is already installed on your customers' phones. No account to create, no app to download, no form to fill in. The conversation starts with one tap, right where your customers already spend their day.

What does a typical WhatsApp sales journey look like?

The typical journey has four steps: a Meta click-to-WhatsApp ad, a conversation, a booking, then a payment link. In practice, your Facebook or Instagram ad opens a WhatsApp chat directly instead of sending people to a website. The prospect asks a question, you answer, you offer a time slot or a product, then you send a payment link. No friction, no cart abandoned halfway through an endless checkout funnel.

Budget-wise, plan at least 300 € of ad spend per month to get usable results, and give Meta's algorithm 2 to 4 weeks of learning before judging performance. Our Meta Ads page explains how these campaigns work.

What do you get for free with WhatsApp Business?

The WhatsApp Business app is free and already covers the essentials for a small operation. Three features make a daily difference:

• The catalog: your products or services with photo, price and description, browsable without leaving the chat.
• Quick replies: shortcuts for your recurring messages (opening hours, prices, address), sent in two taps.
• Labels: a simple way to sort your conversations (new customer, order in progress, payment received) so nothing slips through.

Add a complete profile and an away message, and you have a working conversational storefront in about an hour.

How do you reply 24/7 without hiring?

The answer is an AI assistant plugged into your WhatsApp that replies on your behalf when you cannot. This is the weak spot of conversational selling: messages arrive in the evening, at weekends, in the middle of service. Every hour without a reply lets the prospect's interest fade.

Zazapp, the messaging AI agent built by Neting, replies 24/7 in 15 languages, qualifies enquiries, books appointments and takes payments via Stripe, from 44 €/month. It works on WhatsApp as well as Instagram, Messenger, Telegram, TikTok and email. To understand what a conversational agent can do for a small business, read our guide on AI chatbots for SMBs.

WhatsApp Business alone or an AI assistant: which one?

WhatsApp Business is enough to get started; the AI assistant pays off as soon as message volume exceeds what you can handle by hand.

The right approach is gradual: start on your own, measure the volume, automate once you start losing sales for lack of time.

Which rules must you follow to avoid getting blocked?

Three rules protect your account: consent, the reply window and restraint in outbound messages. First, only contact people who have agreed to be contacted: a customer who writes to you first, or who has given explicit permission. Second, respect the reply window: after a customer's last message you have a limited window of 24 hours to reply freely; beyond that, only pre-approved message templates are allowed. Finally, do not spam: unsolicited bulk sends lead straight to your number being blocked.

Data protection rules apply too: keep proof of consent and offer a simple way to opt out. Under the GDPR, fines can reach 20 M€ or 4 % of worldwide turnover, so treat consent as seriously as any contract.

How do you get started in 5 steps?

You can launch your WhatsApp sales channel in one to two weeks:

1. Install WhatsApp Business and complete your profile: hours, address, description.
2. Build your catalog with your 5 to 10 best-selling products or services.
3. Prepare your quick replies and your labels.
4. Launch a Meta click-to-WhatsApp campaign with a test budget of 300 €/month.
5. When volume grows, plug in an AI assistant so no message ever goes unanswered again.

How much does full-service support cost?

Neting's Growth plan costs 690 €/month and covers the whole chain: Meta campaigns in 3 languages, 10 landing pages, WhatsApp AI messaging, appointment booking, catalog and payment gateway, for an ad budget from 600 €/month. For comparison, campaign management on the market runs between 690 and 4 000 €/month. Quotes are free, with a reply within 24 hours through the website form.
