The courses are sold on third-party platforms, but the platforms take a 20-50% commission. The more courses you sell, the less money you will get! 3. The courses are sold through third-party systems, but an annual usage fee of over 5,000 yuan is required, and authorization for use is also necessary. It's like a bottomless pit. The more you invest, the harder it is to recoup your investment! There are already tens of thousands of course resources. If you don't build your own knowledge payment website, these course resources will be of no value at all! Benefits of building a knowledge payment website: 1. Continuous passive income. 2. Free and easy work. 3. Reduced customer acquisition costs. 4. Expanded income sources. Customer case testimonies: Sister Rong Previously, the food expert had always sold his food courses on third-party platforms. For each course sold, the platform would take a 30% commission, resulting in a very small actual amount received. Later, he bought the Gozesen knowledge payment system to build a food teaching website. Each course was sold for 99 to 399 yuan, and VIP members were 399 yuan per month. The website now earns over 10,000 yuan every month. Lu Xiaomi: Fitness experts love to teach people all kinds of fitness knowledge and often record fitness video tutorials. However, these tutorials have never been able to generate revenue. They built a website specifically for teaching people fitness with the Guozesen knowledge payment system and made profits by selling VIP members. Currently, the website has over 8,000 yuan in VIP income per month. Mr. Xie, the CEO and UI designer, has his own physical company. Every day, there are teachers teaching various UI design courses, but none of these courses can be monetize. Later, he built a UI design teaching website using the Gozesen knowledge payment system. The website makes profits solely from selling courses, with course prices ranging from 399 to 2,999 yuan. Currently, the website earns over 20,000 yuan per month. Mu Zijing: A gaming expert enjoys playing all kinds of games. She has excellent skills and unique gameplay. Later, she recorded her gameplay experiences as video courses and sold them through the Guozesen knowledge payment system. Each course costs 99 to 199 yuan. Now, she earns over 30,000 yuan a month just from selling game strategy tutorials. Teacher Ge: Previously, film and television creators had been using third-party systems to sell their courses, but they had to pay over 6,000 yuan in usage fees each year. If they didn't renew, all their courses would be emptied, just like a bottomless pit. Later, a film and television creation teaching website was built using the Gozesen knowledge payment system. Now, the website earns over 50,000 yuan per month by selling courses and VIP members. System setup requirements: 1. Baota Panel (environment: Nginx+PHP7.2-7.4+ mysql 5.5-5.7) 2.
