SAP is a well-established and highly popular ERP system used by large enterprises around the world. It has a broad range of modules and functionalities, from finance and accounting to human resources and supply chain management. However, its licensing costs can be very high, and its implementation can be complex and time-consuming.

It is highly modular and can be extended through the development of new modules and functionalities. As an open-source solution, iDempiere offers lower licensing costs and more freedom for customization.
In summary, SAP may be a better choice for large enterprises with complex requirements and established budgets, while iDempiere may be a better choice for smaller organizations or those with more flexible requirements and budgets.
