It's easy to use and has all the features one needs for an On Demand booking system. Nothing really as I have been using it for quite some time now. However, the support team is excellent, they are always willing to help out. If you want to develop a robust taxi booking platform then this is what you should go for. Their support is also top notch at times when you need assistance in using their product. We needed a robust taxi booking solution for our clients who wanted to book taxis via mobile app. This helped them track their journey and give feedback on their experience. I like how it's easy to use once installed without any prior knowledge of coding or programming needed. It also has an excellent customer support team who are always there when required. Nothing so far really! Customer service is great but they do need more employees in their office since sometimes emails never go through or take time to reply back. Definitely worth trying out if looking into creating an On demand taxi booking solution. We were solving our customers' problem finding cheap cab services.
