I’ve been using this app on our room-booking website and it has been extremely helpful. When a customer cancels their booking, the ‘back in stock / notify me’ feature instantly alerts other interested customers. It has improved our booking flow and reduced the number of missed opportunities. Very useful and easy to set up!

The GrootApps - Back in Stock app is really helpful for our store. Customers like getting quick alerts when products come back, and it has definitely helped us bring in sales we would have lost otherwise. Setup was simple and their support team is always ready to help.
