i like to be able to get income beside the freelance jobs , something that can generate revenue , i was wandering is there any good market niche that i can build software and sell l it ? plugs-ins or desktop apps
as an add-on question... does anyone have experience with selling wordpress plugins? is there a market for commercial plugins, or are most people not willing to pay since there is a lot of free stuff?
There are also "add-on" stores for big SaaS platforms such as Salesforce.
