VoiceBots can also trigger processes and help your customers as a digital assistant. You can even give your customers the opportunity to receive offers and create orders by linking your VoiceBot to various internal systems. Please have a look at our case studies: HypoVereinsbank, 123tv, and ITDZ for more ideas.
As for the budget:
Of course it is no secret that the conception and development of a VoiceBot costs money. But this should not be an obstacle. It's best to start with a small, manageable usecase. In the process, you and your employees learn from the experience with your first VoiceBot, take advantage of it and use the success stories for further developments.
