Reselling software gives you many of the benefits of a software business, without the upfront development cost.
That means you can enjoy recurring revenue, selling one product to multiple customers, and strong profit margins by white labeling a software tool that already exists.
These benefits are what attract many people to starting a SaaS, or software as a service, but you may not need to go through the trouble.
After all, there may already be a tool that solves the same problem. Could you become a software reseller instead of a software creator?
