WHMCS

Software introduction
WHMCS is a set of popular foreign domain name host management software. Like the well-known IDCSystem in China, it is designed to be very user-friendly in terms of user management, financial management, domain name interface, server management panel interface, etc. WHMCS is a set of one-stop management software that fully supports domain name registration management and resolution, host activation management, VPS activation management and server management. It has been familiar and understood by more and more Chinese webmasters. As a well-known foreign financial system, various domestic management systems have tried to use API interfaces to develop secondary functions. For example, the VPS management system Xensystem used by many domestic IDC companies has been successfully connected to WHMCS, released and is in use. This move caters to the needs of many Chinese IDC vendors who are accustomed to using foreign systems. Coupled with the continuous improvement of Xensystem and other VPS systems, I believe WHMCS will develop further in China.
The latest version is 5.2.7

Although there are many functions, the background management interface is easy to use and the design is very user-friendly.
