SevenRooms WhatsApp: What You Actually Get (and What's Missing to Convert)

“Does SevenRooms do WhatsApp?” Yes, in one direction only. Sending a message from the booking system and handling a message from a guest who writes first are two different mechanics, with two Meta permissions and two ways of routing the reply. SevenRooms launched “WhatsApp Messaging” in 2024: that is the first one. When a guest messages you to book or ask a question, there is nothing on the other side. Here is where that line falls, what it costs, and what to check before you pay for the add-on.

• 98% WhatsApp open rate (vs 20% for email) (SevenRooms, 2024)
• $600–900/mo SevenRooms cost with WhatsApp add-on enabled (Industry sources, 2026)
• 62% of guest enquiries arrive outside opening hours (observed across the Heep base)

What SevenRooms WhatsApp Messaging actually does

SevenRooms announced their WhatsApp integration as "fully integrated". The word is accurate; the scope is narrower than it sounds. In practice:

Included:

• Automated booking confirmations sent via WhatsApp
• Pre-service reminders to reduce no-shows
• Reconfirmation requests and personalised outbound messages
• WhatsApp marketing campaigns (offers, events, birthdays)

Not included:

• Receiving and processing inbound WhatsApp messages automatically
• AI replies to guest questions (availability, hours, menu, allergies)
• Booking creation from a WhatsApp conversation autonomously
• Self-service modifications and cancellations initiated by the guest

That is a plumbing detail that changes everything in use. A guest who receives a WhatsApp confirmation will reply in the thread, because replying is the obvious thing to do: move the time, ask for an outdoor table, flag an allergy. On the SevenRooms side, that reply lands in a mailbox nobody reads during service.

The real cost of the SevenRooms WhatsApp add-on

SevenRooms doesn't publish pricing, but industry sources converge: the base tier starts around $499/month per venue, and the WhatsApp add-on pushes the bill into the $600–900/month range, roughly £475 to £710 at current exchange rates.

At that price you are paying for an outbound notification channel. Not a conversation channel. Handling inbound traffic requires an additional third-party service, and that stays true at any contract tier.

How to handle inbound WhatsApp on SevenRooms

Three ways to close the gap, each with what it leaves uncovered.

Option 1: Dedicated host watching the WhatsApp inbox

This is what most premium SevenRooms restaurants do today. A host replies manually to inbound messages, retypes the booking into SevenRooms. Works as long as someone is available during and outside service.

Hidden cost: around 45 hours/month if you process 50 enquiries/day, equivalent to about £850 in staff time per venue, for a task that is entirely repetitive.

Option 2: Hostie (official SevenRooms integration)

Hostie is the agent integrated into SevenRooms. It replies notably by SMS, and handles bookings, modifications and event enquiries in 20 languages.

Limits: covers SMS, but conversational WhatsApp and Instagram aren't the primary focus. No transparent pricing, quote-based sales process.

Option 3: Heep (multichannel native SevenRooms integration)

Heep is the conversational AI agent listed on SevenRooms' integrations page: "heep.ai is an AI-driven platform that automates customer interactions on social media channels such as WhatsApp, Instagram, and Messenger." It replies to inbound messages on WhatsApp, Instagram, Messenger and email, in the guest's own language, and writes the booking into SevenRooms via the official API. A call nobody could take is followed up in writing too: WhatsApp first, SMS as the fallback.

Guest types "Table for 4 tonight", Heep checks SevenRooms availability, proposes a slot, confirms, sends the WhatsApp confirmation. All in the same conversation, no human input.

How Heep and SevenRooms talk in practice

The integration runs both ways through the official SevenRooms API:

• Real-time availability lookup — Heep queries your SevenRooms calendar: capacity, tables, services, exceptions, paid experiences (chef's table, terrace, private room).
• Booking creation with metadata — when a guest confirms via WhatsApp, Heep pushes the booking into SevenRooms with a source tag so you can track attribution in your reports.
• Rich Guest Profile enrichment — preferences (allergies, birthdays, preferred table) surfaced in conversation feed straight into the SevenRooms guest profile.
• Modification sync — guest writes "move to 9pm" or "cancel" on WhatsApp, Heep updates SevenRooms and releases the table immediately.

What this changes on ROI (client data)

Three measurable effects across SevenRooms restaurants running Heep:

1. Out-of-hours recovery. Average of 14 additional bookings per month created between 11pm and 9am, the window when nobody's watching WhatsApp. At a £30 average cover, that's around £1,400 in monthly revenue recovered per venue.

2. International coverage for premium groups. SevenRooms is dominant on Michelin and premium restaurants with international clientele. With Heep, a Japanese tourist messaging in Japanese on Instagram walks away with a confirmed SevenRooms booking, no bilingual host required.

3. Host relief during service. Messages keep coming during rush, and missed calls too. Heep absorbs 80–90% of inbound messages at those moments and follows up missed calls by WhatsApp, then SMS, letting the host focus on greeting walk-ins and arriving guests.

Verdict: should you pay for the SevenRooms WhatsApp add-on?

If you operate 3+ venues and your use case is primarily outbound marketing and CRM, the SevenRooms WhatsApp add-on makes sense: you stay in a unified ecosystem and you get the native Rich Guest Profiles.

If your problem is losing inbound WhatsApp and Instagram enquiries, the add-on doesn't solve it, at any tier. In that case Heep covers four channels instead of one and integrates into your SevenRooms without replacing anything.

Before you decide, check two things. The SevenRooms API access level open on your contract and in your region: the widget alone cannot write a booking. Then the status of your WhatsApp Business number, since a number can only be attached to one integration at a time. Those two answers settle it more reliably than the price does.
