Hey everyone, I’m working on an MVP for a review management SaaS for restaurants and I’m trying to figure out the best workflow. The idea is to automatically send a WhatsApp message asking for feedback/review after the customer has actually visited the restaurant, not simply after making a reservation. The problem is: - For customers who book a table, we have their name and phone number, but we don't know exactly when they actually finish their meal. I could have the staff manually mark them as “served”, but ideally I’d like this to be automated. - For walk-in customers, we often don't have their phone number at all. My ideal setup would be something like: Customer pays → POS/restaurant management system detects the completed transaction → triggers the review request → WhatsApp message is sent 30–60 minutes later. Is this realistically possible through integrations/APIs with restaurant POS or management systems? And if so, which restaurant management/POS systems would be worth integrating with first, especially in Europe/Italy? I’m trying to keep the MVP simple and avoid building a different integration for every system, so I’d really appreciate advice from people who have experience with restaurant tech.
