WhatsApp Marketing for Restaurants: A Beginner's Guide

Bring back customers, share offers, and build loyalty โ€” all through WhatsApp

๐Ÿ“ฑ Why WhatsApp is the Best Marketing Channel for Indian Restaurants

India has over 500 million WhatsApp users. Your customers โ€” regardless of age or tech-savviness โ€” use WhatsApp every day. Unlike Instagram or email, WhatsApp messages are opened within minutes. For local restaurants, this makes WhatsApp one of the highest-ROI marketing channels available, with near-zero cost.

What restaurants use WhatsApp for:
  • Sending digital bills after every meal
  • Sharing weekend specials and new menu items
  • Announcing festive offers (Pongal, Diwali, New Year)
  • Collecting post-meal feedback
  • Sending reorder reminders to regulars

๐Ÿš€ Step 1: Build Your Customer WhatsApp List

Every customer who dines at your restaurant is a potential WhatsApp contact. The key is collecting numbers with consent at the right moment.

  1. Collect numbers at billing When the cashier generates a bill in Unavakam, the system can optionally ask for a phone number to send the digital invoice. Enable "WhatsApp Invoice" in Settings โ†’ Billing. This builds your list automatically.
  2. Add a QR code at the table Place a small card: "Join our WhatsApp for exclusive offers โ†’ [QR]". This takes the customer to a WhatsApp pre-filled message that adds them to your broadcast list.
  3. Ask at the counter Train your cashier to say: "Can I send your bill and future offers on WhatsApp?" Most customers agree. Note: always get explicit verbal or written consent โ€” do not spam unsolicited numbers.

๐Ÿ“ฃ Step 2: What to Send (and When)

  1. Digital bill after every meal Unavakam sends a PDF bill via WhatsApp automatically when the cashier clicks "WhatsApp Invoice". Customers love the convenience, and it keeps your restaurant name in their chat list.
  2. Weekend special (Friday 11 AM) Send a short message with your weekend special: "This Saturday: Fresh Mutton Biryani + Raita for โ‚น189. Limited portions. Book your table: [link]." Keep it under 3 lines. Include a food photo when possible.
  3. Festive offers (2 weeks before the occasion) Examples: Pongal thali advance booking, Diwali sweets pre-order, New Year dinner reservation. Festive messages see 3x higher response rates than regular promotions.
  4. Re-engagement for dormant customers In Unavakam Reports โ†’ Customer Visits, filter customers who haven't visited in 30+ days. Export the list. Send a personal message: "We miss you! Come back this week and enjoy a complimentary dessert." This wins back 15โ€“20% of lapsed customers.

โœ๏ธ Message Templates That Work

New dish announcement:
"Hi [Name], ๐Ÿ› NEW on our menu โ€” Chettinad Chicken Gravy. Available from this Monday. Come taste it! Book a table: [link] โ€” [Restaurant Name]"
Festive offer:
"๐Ÿช” Diwali Special! Full family thali (6 items) at โ‚น249 per person. Available Oct 20โ€“23. Pre-book now to guarantee your table: [link] โ€” [Restaurant Name]"
Re-engagement:
"Hi [Name], it's been a while! ๐Ÿ˜Š Visit us this week and enjoy a FREE dessert on us. No coupon needed โ€” just mention this message at billing. We'd love to see you again! โ€” [Restaurant Name]"

โš ๏ธ Rules to Follow (and Avoid Getting Blocked)

  • Never message customers who didn't give consent
  • Send max 1โ€“2 messages per week (avoid daily broadcasts)
  • Always include an easy opt-out: "Reply STOP to unsubscribe"
  • Don't use WhatsApp Business API for mass spamming โ€” it violates Meta's policies
  • Personalize when possible โ€” use the customer's first name
