WHMCS is a very easy-to-use financial management system. Except for a few foreign VPS hosting companies that have developed their own financial systems, most hosting companies (such as classic VPS) use WHMCS. WHMCS can be used to sell hosts, domain names, space, etc., as well as accounts, virtual downloads, certificates, etc. But if WHMCS is used in China, one of the biggest problems is the WHMCS payment gateway problem. WHMCS comes with Paypal, but gateway interfaces such as Alipay and WeChat need to be developed before they can be accessed. Fortunately, there are many WHMCS players in China, and many free and open source WHMCS Alipay plug-ins can be downloaded and used for free. This article will share several WHMCS payment gateways: weloveidc WHMCS-Payment-Gateway-alipay, f2faliPay For WHMCS v2.9, 52fancy whmcs-alipay and Whmcs payment gateway Youzan (Alipay + WeChat). To learn more about how to use WHMCS, see: WHMCS from beginner to proficient.
