WhatsApp for Restaurants: How to Use It for Bookings and Customer Communication
By Reserva
Why WhatsApp Is Now a Hospitality Tool
Over 45 million people in the UK use WhatsApp, and for many demographics it's the primary communication channel. A message sent via WhatsApp is more likely to be seen, read, and responded to than a text or email — which makes it an increasingly important tool for UK restaurants managing bookings and customer relationships.
WhatsApp Business, the platform's free app for businesses, adds features specifically useful for hospitality: automated greeting messages, quick reply templates, product catalogues, and business profile information. WhatsApp Business API goes further, enabling automated messaging integrated with booking systems.
WhatsApp for Booking Confirmations and Reminders
The most immediate application for restaurants is using WhatsApp in place of — or alongside — SMS for booking confirmations and reminders. The advantages over traditional SMS:
- **Read receipts**: You know when the customer has seen the reminder, not just when it was delivered
- **Richer formatting**: Bold text, line breaks, and links display properly rather than as plain text
- **Two-way conversation**: Customers can reply with questions or to confirm, and your team can respond in the same thread
- **Higher trust**: Messages arrive from a verified business profile, not an unknown number
A WhatsApp reminder that reads "Hi James — your table for 4 at The Oak is confirmed for Saturday at 7:30pm. Reply to this message if you have any questions. We look forward to seeing you!" feels qualitatively different to the equivalent SMS.
Setting Up WhatsApp Business for Your Restaurant
WhatsApp Business App (free): Suitable for smaller operations where a single staff member manages customer messaging. You get a business profile, automated greeting messages, and quick reply shortcuts. Limitation: only usable on one device at a time.
WhatsApp Business API (via a provider like Twilio): Suitable for businesses that want WhatsApp integrated into their booking system, with automated messages sent without manual staff input. Requires a registered WhatsApp Business number and approved message templates.
For restaurants using a booking system with WhatsApp integration, automated confirmation and reminder messages can be sent via WhatsApp at the same trigger points as SMS — without any additional staff action.
Managing Inbound Customer Messages
WhatsApp's two-way nature means customers will reply to messages. This is a feature, not a problem — but it does require a clear process for who handles inbound messages and how quickly.
Best practices:
- Set a WhatsApp auto-reply for out-of-hours messages that acknowledges receipt and gives expected response time
- Ensure at least one team member monitors WhatsApp during service hours
- Use the WhatsApp Business label feature to tag conversations (e.g. "booking query", "complaint", "compliment") for easy management
WhatsApp for Group Booking Management
Group booking organisers frequently prefer WhatsApp for ongoing communication — changing guest counts, dietary requirements, and logistics updates are more naturally handled in a messaging thread than over email. Proactively offering group bookers a WhatsApp contact for pre-event communication is increasingly valued.
A group organiser who can easily message "we'll be 9 not 10" and receive a quick confirmation is a more confident, committed customer.
The Privacy Consideration
UK GDPR applies to WhatsApp communications in the same way as email and SMS. You need a legitimate basis for sending marketing messages (typically explicit consent), and customers must be able to opt out. Transactional messages — booking confirmations and reminders — have a stronger legitimate interest basis than promotional ones.
Ensure your booking flow includes clear language about how you'll contact customers, including WhatsApp if applicable.
