I am using dataprovider for my travel company. We use it for all our online booking needs, like hotel, flights, and car rentals. It is very simple to use and the customer support is top notch. The price is also very reasonable. There is nothing I dislike so far. The only thing I dislike is the lack of a mobile app. I wish there was a mobile app to use on the go. I highly recommend this product. DataProvider helps us to maintain a database of hotels, flights, and car rentals. It helps us to keep track of our inventory. It also helps us to keep track of our sales.
