While these models have diminished in mature e-commerce and online advertising markets they are still prevalent in some more nascent industries. China is one example where Affiliate Marketing does not overtly resemble the same model in the West. With many affiliates being paid a flat "Cost Per Day" with some networks offering Cost Per Click or CPM.
Because 2Checkout exclusively sells software and digital products, it is best suited for established influencers whose target audience is interested in buying products in this niche. But while you won’t find any physical products for sale, 2Checkout is probably the market leader in selling software of every type, including very specific use case items (like software that can convert Microsoft Word documents to PDF, for instance).
The only difference with the offline middleman and affiliate business program is that the online affiliate does not need to get hold of the actual product to earn revenue. He doesn’t need to shell out money to buy the product that he has to sell. All he has to do is create a site that markets the products of the producer. Every time he makes a sale, the producer will take over to send the actual products, receive payments and extend customer support, when necessary. A special web-based script records this process and thus the affiliate is paid for every successful sale he makes.
