Software packaging initially provided customer service for WinNexus when selling products. With the rapid increase in the number of customers, the speed of software packaging was not enough to meet customer needs, which became a bottleneck for our after-sales service. In order to solve this problem once and for all, WinNexus turned this service into a tool, and created an exclusive packager, which can be easily used even by non-IT personnel, and independently packaged software, which is highly accepted by customers. We continue to improve the packager, expand and update more practical application software and systems in real time, give customers more software choices, and improve the efficiency of MIS.
