OUR STORY/Original Intention and Advice The original intention of Zhiyanfa is to enable enterprises and teams with communication needs to have their own instant messaging products more conveniently: the interface is user-friendly, the functions are practical, and the deployment methods and data management can also be in their own hands. We aim to transform complex technical capabilities into tangible and practical products, and at the same time, clearly explain the delivery content of each package, enabling customers to make choices based on their own needs. We value every genuine experience and also hope to make the promised matters clear and well done during product iteration, deployment and subsequent communication, so that every cooperation is built on understanding and trust. Before purchasing an IM system, here is a sincere piece of advice for you. When choosing a system, it is recommended that you first watch a real demonstration, personally experience the chat and the back-end, and then verify whether what you have bought is a finished product or a source code. For those requiring secondary development, it is necessary to clarify whether the source code is complete, whether key functions can be modified, and the specific scope of deploying and updating services. At the same time, get to know in advance the possible costs involved in servers, domain names, text messages, push notifications, and application listings, and confirm the delivery list, after-sales service period, and mutual agreements clearly. No matter which one you ultimately choose, it will be more convenient to carry out business in the future if it suits your actual needs and you can understand the delivery content.
