How to make money on cheap software, or the GWS business model

I am writing this post because for many people it may seem strange why Green Work Schedule is so cheap. inEwi charges between 10.95 zł and 19.95 zł per user, Kadromierz between 12.99 zł and 19.99 zł per employee, and ProPlanum between 12 and 18 zł per employee.

There are actually 2 ways to make money with this type of application. The first is Software as a Service (SaaS), which is what the companies mentioned above do: prepare one universal tool that many different companies can use and sell a subscription. The second is writing dedicated software — creating an application for one specific company to meet their specific needs.

In the case of SaaS applications, the difficulty is to come up with something original that is not yet on the market. In the case of dedicated applications, the difficulty is marketing — convincing the client that our company can create such software better than anyone else.

The business model of Green Work Schedule is to create software that attracts as many clients as possible. Then, once clients are satisfied with its operation, when they need dedicated software, they will be more willing to look at our company. On top of that, we can offer consulting services.

This approach is common in the industry of tools intended for IT professionals (programming libraries, databases, etc.), so it is time for it to also take root in other industries.
