ChatApp allows you to create a cloud contact center for multichannel customer service. Operators can receive messages from various channels, such as messengers and social networks, all in one window. For example, if a client writes through WhatsApp or Telegram, the message goes to ChatApp, and the operator replies, with the response returning to the same channel. The system keeps a complete history of conversations and client information. Everything works smoothly, messages are delivered instantly, and no information is lost. To simplify operators' work, there are quick response templates, and to replace operators at night, you can create a chatbot, which doesn't require special skills – the bot is set up in a user-friendly interface. You can also configure dialogue distribution scenarios, monitor operator activity, and track statistics on customer interactions. A CRM for working with clients is not needed. The contact center operates in the cloud, but integrations with amoCRM, Bitrix, and YClients are available.
