Toast + DMHub: Automate Google Review Collection via WhatsApp

Google reviews are the single most important factor for local restaurant discovery. A restaurant with 200 reviews and a 4.5 rating will outperform a restaurant with 30 reviews and a 4.8 rating in search results every time. Volume matters as much as quality.

The problem is getting reviews. Asking customers face-to-face feels awkward. Table tent cards get ignored. Email requests have a 3% conversion rate. WhatsApp requests, triggered automatically after a Toast transaction, convert at 12-15%.

How It Works

The flow is straightforward:

1. Customer pays their bill (Toast POS records the transaction)
2. DMHub receives the transaction data via webhook
3. 2 hours later, a WhatsApp message asks about their experience
4. Happy customers are directed to Google Reviews
5. Unhappy customers are directed to a private conversation with the manager

This routing is the key innovation. You want positive feedback public and negative feedback private.

Setting Up the Automation

Create the Feedback Template

``` Hi {{name}}, thanks for visiting {{restaurant}} today!

Quick question — how was your experience?

Reply with a number: 5 - Loved it 4 - Really good 3 - It was okay 2 - Not great 1 - Disappointed ```

Configure the Response Routing

If reply is 4 or 5: ``` So glad to hear that! Your feedback means the world to us.

Would you mind sharing a quick review on Google? It helps other food lovers find us: {{google_review_link}}

Takes 30 seconds and makes a huge difference. Thank you! ```

If reply is 1, 2, or 3: ``` We're sorry your experience wasn't great. We take this seriously.

Our manager {{manager_name}} would like to hear what happened and make it right.

What went wrong? We'll respond personally within the hour. ```

Negative feedback goes directly to the manager's DMHub inbox. The response feels personal because it is — a real person follows up.

The Math Behind Review Collection

A restaurant serving 150 dine-in customers per day with WhatsApp numbers captured for 40% of them:

• 60 customers receive a WhatsApp review request daily
• 55% respond to the rating question (33 responses)
• 80% rate 4-5 stars (26 happy customers)
• 45% of those leave a Google review (12 new reviews per day)

That's 360 new Google reviews per month. In 3 months, you'd go from whatever your current review count is to having one of the most-reviewed restaurants in your area.

Maximizing Review Quality

Tips from restaurants collecting 200+ reviews monthly:

1. Timing matters. 2 hours post-meal is optimal. Customers have left, digested the experience, but it's still fresh. Sending immediately feels transactional.

1. Don't review-gate on the review page. Google prohibits asking only happy customers to leave reviews. However, you can ask all customers for feedback privately on WhatsApp and then offer the Google link to everyone. The happy customers will naturally follow through.

1. Respond to every Google review. When potential customers see the owner responding to reviews, they're 68% more likely to leave their own.

1. Include the server name. "How was your experience with Sarah today?" personalizes the request and increases response rates by 22%.

1. Rotate your ask. Some weeks ask about the food. Others ask about the ambiance or service. This diversifies your review content, which helps with SEO.

Handling Negative Feedback

The private channel for unhappy customers is where service recovery happens. Best practices:

• Respond within 1 hour
• Acknowledge the issue specifically
• Offer a concrete resolution (not just "sorry")
• Invite them back with a complimentary experience
• Follow up after their return visit

Restaurants that handle negative feedback well convert 40% of complainants into repeat customers. The WhatsApp conversation creates a private, personal channel for this recovery.

Getting Started

Review collection is a compounding investment. Every review improves your Google ranking, which brings more customers, who leave more reviews. Toast provides the transaction trigger. DMHub delivers the WhatsApp message. The reviews take care of themselves.
