This is something I found amazing about WeChat as well. You can schedule appointments with barbers, doctors, physicians, etc all through custom interfaces implemented by 3rd party vendors within the app. It's kind of like its own operating system. And for all of the needs that aren't already covered, you can always resort to basic text messaging (again through WeChat). This probably covers 100% of business communications: customers talking to vendors, vendors talking to customers, and vendors talking to other vendors. The only thing missing as far as I know is a way to communicate with government entities to e.g. file paperwork and such. But I'm sure that will come in time.
