They are complete ERP implementations, based on our alpha360 data models. Think of them as "templates" - that let you implement your own ERP - using WINDEV, WEBDEV or .NET/C#.
Commercial implementations are available for WINDEV21, WEBDEV21 and .NET/C#. They include full source code, support and royalty free distribution of your compiled applications.
The alpha360 Data Models and the core WINDEV21 ERP implementation are both Open Source. Download them, study them and use them in whatever way you like.
