Everything a new business owner needs to set up WhatsApp Business correctly the first time — from download to first customer message.
Step 1 — Download and Register Your WhatsApp Business Number
WhatsApp Business is a separate app from WhatsApp Messenger. Download it from the Google Play Store or Apple App Store — search exactly for 'WhatsApp Business' to avoid confusion with the standard version. The app is free for small businesses using the basic version.
During registration, use your business phone number — not your personal number. If you need both personal and business WhatsApp, use two separate SIM cards or register WhatsApp Business on a secondary number. The business number will become your public contact for all customers, so choose it carefully. A dedicated business SIM that stays active permanently is preferable to a number that might change.
Verify your number via SMS OTP. If you currently use that number on WhatsApp Messenger, the app will offer to migrate your chat history. Accept this only if you need historical messages; otherwise start fresh for a cleaner business account.
Step 2 — Complete Your Business Profile Fully
Tap the three dots menu → Settings → Business Tools → Business Profile. Fill every field without exception: business name (exactly as customers know you), business category (choose the closest match from the dropdown), description (two sentences explaining what you do and who you serve), address, business hours, email, and website if you have one.
Your profile picture should be your logo, not a personal photo. Minimum 640x640 pixels, clear background preferred. WhatsApp profile pictures display at a small size so ensure your logo is readable even at 50x50 pixels.
The business description field allows 256 characters. Use it to state your main service, your city or region, and your primary differentiator. Example: 'Kerala handmade jewellery — custom gold and silver pieces designed to order. WhatsApp orders accepted. Ships across India and GCC.' This tells a new contact everything they need to know before sending their first message.
Step 3 — Set Up Greeting Messages and Away Messages
Go to Business Tools → Greeting Message. Enable it and write a message that goes out automatically when someone contacts you for the first time or after 14 days of no contact. A good greeting acknowledges the customer, sets expectations for response time, and tells them what information to include: 'Hello! Thank you for contacting [Business Name]. Please share your requirement and we will respond within 2 hours during business hours (Mon–Sat, 9 AM–7 PM).'
Away Messages go out when someone contacts you outside your set business hours. Enable this, set your business hours under Business Profile, and write an away message that includes when they can expect a response: 'We are currently closed. Our business hours are Mon–Sat 9 AM to 7 PM IST. We will reply to your message first thing when we open. For urgent matters, email hi@yourbusiness.com.'
Never leave both messages blank. The first impression a new customer gets determines whether they wait for your reply or move to a competitor. A professional automated response signals that this is an active, organised business.
Step 4 — Set Up Quick Replies for Common Questions
Quick Replies let you save template responses that you can send with a keyboard shortcut. Go to Business Tools → Quick Replies. The shortcut is a single word you type after a forward slash — e.g., /price brings up your pricing message.
Suggested quick replies for most Indian businesses: /price (your pricing or rate card), /location (your address with Google Maps link), /hours (business hours), /payment (accepted payment methods and UPI ID), /delivery (delivery timeline and areas covered), /quote (instructions for requesting a quote), /thankyou (post-purchase acknowledgement message).
Create these before you start using the app with customers. Once you have 8–10 quick replies set up, most routine customer questions take under 5 seconds to answer professionally.
Step 5 — Add Your Product Catalogue
The WhatsApp Business catalogue allows you to list up to 500 products or services. Go to Business Tools → Catalogue → Add New Item. Add a high-quality photo, product name, description, price, and a link to your website product page if applicable.
For service businesses, create catalogue entries for your main service packages. A digital marketing agency might list 'Social Media Management — ₹12,000/month (includes 12 posts, 3 reels, daily story, monthly report)' as a catalogue item. This eliminates back-and-forth on pricing for standard packages.
Once your catalogue is live, you can share individual items or the full catalogue directly in a chat by tapping the attachment icon → Catalogue. Customers can browse and share items they are interested in without leaving WhatsApp.
What to Do in Your First Week With WhatsApp Business
- Share your new WhatsApp Business number on all existing channels — Instagram bio, Google Business Profile, your website contact page, business cards
- Add a click-to-chat link (wa.me/91XXXXXXXXXX) to your website's contact button
- Import your existing contacts and send them a broadcast introducing your new business number
- Test every automated message by having someone outside your business send you a message and checking that the greeting appears correctly
- Review the Insights tab (if on Android) to see message statistics after the first few days
Frequently Asked Questions
Can I use WhatsApp Business on the same phone as WhatsApp Messenger?
Yes. From 2021, WhatsApp allows both the standard Messenger app and WhatsApp Business app on the same device, provided they use different phone numbers. You cannot use the same phone number for both apps simultaneously. Most business owners use their personal number on WhatsApp Messenger and a dedicated business SIM on WhatsApp Business.
Is WhatsApp Business App free for small businesses in India?
Yes, the WhatsApp Business App is completely free to download and use for small businesses. The free version includes all basic features: business profile, catalogue, quick replies, greeting messages, away messages, and labels. The paid WhatsApp Business Platform (API) is separate and intended for larger enterprises needing integration with CRM systems and automated messaging at scale.
What is the difference between WhatsApp Business App and WhatsApp Business Platform?
The WhatsApp Business App is a free mobile app for small businesses — you manage everything manually from your phone. The WhatsApp Business Platform (formerly WhatsApp Business API) is for medium and large businesses needing automation, CRM integration, multiple agent access, and high-volume messaging. The Platform requires a monthly subscription through a Business Solution Provider (BSP) and typically costs ₹2,000–₹15,000/month depending on message volume.
