WyattERP is an all-inclusive business management software, abbreviated from Enterprise Resource Planning, that offers complete control and organization of a company's resources.
Traditionally, there have been three methods to achieve a true ERP. One is to grow your own software from scratch, the second is to integrate a diverse set of existing commercial applications, and thirdly, to pay for a commercial ERP system. However, off-the-shelf ERP systems always seem to have a pre-determined set of business rules in mind, which may not fit your business.
Integrating existing applications seems like the easiest way to get a custom solution, but it is much harder than it sounds. Each application has its way of storing data, its API, and its operational methodology. It is challenging to get into the internals of the application, which is a must for a true integration project. Furthermore, when applications are not seamlessly integrated across the business, querying data across a wide range of sources and parameters becomes difficult-to-impossible.
Growing your software seems the only way to achieve true custom integration, but the size of the task has made it next-to-impossible for all but the largest enterprises. Companies claim to be able to produce a custom solution, but it seldom pans out as good as it sounded in the sales presentation. And more troubling, you get left with a product your own people don't know how to maintain or extend.
WyattERP has released a set of tools created for the purpose of making it possible for even a small enterprise to develop its own fully-functioning ERP system. Your own IT team can learn to use WyattERP tools to make a database-driven system to run every aspect of your business. You can design your own system that runs according to your company's way of doing business. You will own and understand your design so you can maintain and extend it as much as you like.
Wylib and Wyseman are open source tools used for creating fully customizable, affordable ERP solutions on a Linux platform using PostgreSQL. Wylib provides an easy-to-use, robust application framework, while Wyseman provides a way to create database models using user-defined schema files. Both Wylib and Wyseman interact with the PostgreSQL database to provide an ERP solution seamlessly.
Wylib and Wyseman are released under two licensing options. This dual license allows for a fair exchange, or Quid pro Quo, to take place between the licensee and the licensor (WyattERP). The source code for Wylib and Wyseman is identical for both licenses.
