WhatsApp is not just a messaging app in South Africa — it’s the country’s primary communication channel. With over 24 million active SA users, WhatsApp reaches more South Africans than any social media platform. For Cape Town and Johannesburg businesses, WhatsApp Business is not optional — it’s where your customers expect to communicate, and where leads convert. This guide covers everything you need to set up and use WhatsApp Business as a genuine marketing and lead generation tool for your SA business.

Step 1: Set Up WhatsApp Business Correctly
1. Download WhatsApp Business app from Google Play or App Store
2. Verify using your South African business phone number
3. Set your Business Name — use your exact trading name for trust and discoverability
4. Add Business Category — choose the most accurate category for your Cape Town or Joburg business
5. Write a compelling Business Description (max 256 chars) mentioning your key service and location
6. Add your website URL, email address, and physical address or service area
7. Set your Business Hours — customers see this before messaging
Step 2: Set Up Automated Messages
Away Message
Set an away message for outside business hours so Cape Town and Johannesburg customers receive an immediate response with your expected reply time. Example: “Thanks for contacting Unified Marketing. We’re currently closed but will respond within 2 business hours during Mon–Fri 8am–5pm SAST.”
Greeting Message
Set a greeting message that fires when a new contact messages you for the first time. Example: “Hi! Thanks for reaching out to Unified Marketing. What can we help you with today? We’ll get back to you shortly.” This keeps the lead warm even when you’re away from your phone.
Quick Replies
Create quick reply shortcuts for your most common responses — FAQ answers, pricing information, booking links, and consultation request prompts. These save significant time when managing high enquiry volumes.
Step 3: Build Your WhatsApp Catalogue
WhatsApp Business Catalogue allows Cape Town and Johannesburg businesses to showcase services or products directly within WhatsApp. Add each of your services with name, description, price range, and a professional image. Customers can browse your offerings without leaving the app — reducing friction in the sales conversation.
Step 4: WhatsApp Broadcast Lists for SA Businesses
What are Broadcast Lists?
Broadcast lists allow you to send a single message to up to 256 contacts simultaneously, appearing as a personal one-to-one message in each recipient’s inbox — not as a group chat. This makes them highly effective for promotional messages, special offers, and business updates to your existing client base.
POPIA Compliance for WhatsApp Marketing
Under South Africa’s POPIA (Protection of Personal Information Act), you must have explicit consent to send marketing messages via WhatsApp. Only add contacts who have actively provided their number AND consented to receive marketing messages. Always include a clear opt-out mechanism in broadcast messages.
Step 5: Integrating WhatsApp Into Your Digital Marketing
- Google Ads — run Click-to-WhatsApp campaigns that connect ad clicks directly to your WhatsApp chat
- Facebook & Instagram Ads — Click-to-WhatsApp ads are one of the highest-converting SA ad formats
- Website — add a WhatsApp sticky button on all pages (bottom right, visible on mobile)
- Email signatures — include your WhatsApp number as a clickable link
- Business cards and printed materials — add WhatsApp QR code
WhatsApp Business Best Practices for SA Businesses
| Practice | Why It Matters |
| Respond within 2 hours during business hours | SA customers expect fast WhatsApp responses — delays lose leads |
| Use the customer’s name in first response | Personalisation increases engagement and trust |
| Keep messages concise — no walls of text | WhatsApp is a conversational medium, not email |
| Use voice notes for complex explanations | SA customers relate well to voice messages — humanises your brand |
| Never spam broadcast lists | Opt-out requests must be honoured immediately under POPIA |
| Use professional language matching your brand | WhatsApp doesn’t mean casual — maintain your brand voice |
Frequently Asked Questions
Can I use WhatsApp Business on a landline number in South Africa?
Yes. WhatsApp Business can be verified using a landline number through the voice call verification option. The verification code is delivered via an automated phone call to the landline rather than an SMS. This allows Cape Town and Johannesburg businesses with dedicated office lines to use that number for WhatsApp Business without requiring a mobile number.
Is WhatsApp Business marketing POPIA compliant in South Africa?
WhatsApp marketing can be POPIA compliant if done correctly. You need lawful grounds to process contact information — usually explicit consent from the recipient to receive marketing messages from your business. Never add contacts who haven’t specifically provided their number for business communication purposes. Always offer a clear opt-out mechanism and honour opt-out requests immediately. When in doubt, consult a POPIA compliance specialist.
What is the difference between WhatsApp Business and a regular WhatsApp account for a SA business?
WhatsApp Business includes features specifically designed for South African businesses: a business profile with your company details, automated greeting and away messages, quick replies for common responses, a product/service catalogue, broadcast lists for client communication, and message statistics. These features make customer communication significantly more efficient and professional compared to using a personal WhatsApp account for business purposes.
Should I use WhatsApp Business or WhatsApp API for my Cape Town business?
WhatsApp Business App (free) is suitable for most small and medium Cape Town and Johannesburg businesses handling enquiries with 1–2 staff members. WhatsApp Business API is worth the investment for businesses handling high message volumes, needing multiple agents to respond simultaneously, wanting chatbot automation, or requiring CRM integration. Most SA SMEs start with the free Business App and upgrade to API as their communication volume grows.
How do I add a WhatsApp button to my South African business website?
The simplest method is adding a click-to-chat link using the format: https://wa.me/27662423570 (replace with your number without the + and with the country code 27). Many WordPress plugins create a floating WhatsApp button widget automatically. For maximum lead capture, ensure the button is visible on mobile without scrolling, uses your correct +27 number, and optionally pre-fills a greeting message to reduce the first-contact friction.
