How to sell on WhatsApp in India (catalog → payment → GST invoice)
Last updated:
Selling on WhatsApp in India usually means three jobs: show products clearly, collect payment safely, and send a proper invoice when the customer needs one. You can start with WhatsApp Business alone, then add a store checkout link when orders grow. This guide walks through catalog setup, UPI and COD, when a hosted checkout helps, and how GST invoices fit in—without claiming any platform is “best.”
1. Use WhatsApp Business (not only personal WhatsApp)
Download WhatsApp Business and create a business profile with your shop name, category, address (if you have a storefront), and business hours. Add a short greeting so new chats know you sell products and how you take orders.
Keep one number for customer chats. If you already use a personal number for friends and family, move selling to a dedicated business number when you can.
2. Build a simple product catalog
In WhatsApp Business, set up a catalog (or Collections) with:
- Clear product names and prices in INR
- At least one good photo per item
- Size / colour options in the description when it matters
Share catalog items in chat instead of only sending scattered photos. When someone asks “what do you have?”, send the catalog link or product cards so they can browse.
3. Decide how you take payment
Common options for Indian WhatsApp sellers:
- UPI — Share your UPI ID or QR after the customer confirms the order. Ask them to send a payment screenshot, then confirm.
- Cash on delivery (COD) — Useful for local delivery. Note the address, COD amount, and delivery window clearly in chat.
- Payment link / gateway — When you connect a supported gateway on your online store, you can send a checkout link so the customer pays on a secure page.
Whatever you choose, write the total (product + shipping if any) in the chat before they pay.
4. When to use a store checkout link
WhatsApp works well for discovery and conversation. A store checkout link helps when:
- Customers ask for size/colour options you cannot manage in long chat threads
- You want one place for stock, price, and order status
- You need online payment without chasing screenshots
You can keep Instagram or WhatsApp for discovery, then send a ShopSynq storefront or product link so the customer completes the order on your store. ShopSynq is an ecommerce and retail management platform for Indian small businesses—it does not promise customers or sales; it helps you organise products, inventory, orders, and invoices in one place.
5. GST invoice: when and how
If you are registered under GST and the sale requires a tax invoice, issue one with the correct GSTIN, invoice number, taxable value, and tax break-up. Many sellers prepare invoices from their billing or store software after the order is confirmed—not only as a WhatsApp PDF.
Typical flow:
- Confirm items and amount in chat (or via checkout).
- Collect payment (UPI, COD, or gateway).
- Create the GST invoice in your billing tools.
- Share the invoice PDF or link with the customer.
If you are not GST-registered, follow your accountant’s advice on bills of supply or simple receipts—do not invent tax claims in chat.
6. Keep chats tidy as you grow
- Use quick replies for “price?”, “sizes?”, and “delivery time”
- Save frequent customer details (name, address, preferred payment)
- Move confirmed orders into a single order list so nothing is lost in unread chats
When volume grows, managing products, stock, and invoices only inside WhatsApp becomes hard. That is when a simple online store plus POS/billing workflow (such as ShopSynq) is useful alongside WhatsApp—not instead of talking to customers.
Frequently asked questions
- Do I need WhatsApp Business to sell in India?
- You can take orders on personal WhatsApp, but WhatsApp Business is designed for shops: business profile, catalog, labels, and quick replies. Most growing sellers prefer Business for catalog and clearer branding.
- Is UPI enough, or do I need a payment gateway?
- UPI is enough for many early sellers. A payment gateway or store checkout link helps when you want automated confirmation, cards/netbanking options, or fewer payment-screenshot disputes. Gateway fees are charged by the provider, not as a WhatsApp feature.
- When should I send a GST invoice?
- If you are GST-registered and the sale requires a tax invoice, issue it after the order (and payment terms) are clear. Share it on WhatsApp if the customer asks. Unregistered sellers should use the document type their tax adviser recommends—do not put incorrect GST details on invoices.
- Can ShopSynq replace WhatsApp for selling?
- No. ShopSynq does not replace WhatsApp or promise new customers. It helps you run an online store and manage products, inventory, orders, customers, payments, and GST-ready billing alongside channels like WhatsApp where you already chat with buyers.
