iDempiere is best suitable ERP for small and medium businesses.

Following are the features why I think iDempiere is best.

1. Active community support https://groups.google.com/forum/#!forum/idempiere
2. Technical upgrades are very frequent
3. Plugin architecture , we can plugins for our needs install and play instead of playing and changing or deploying the whole application. The second feature of iDempiere are the plug-ins to modify or extend the ERP, CRM and SCM functionality.
4. Available plugin library http://wiki.idempiere.org/en/Category:Available_Plugins
5. CHUCK: it make it easy to do my job… I do not find myself fighting the software

Functional

Most of the customers I work with are between $X and $Y in yearly turnover and operate in distribution and manufacturing industries. iDempiere has the feature set to support this size organization well.

1. iDempiere is an open source Enterprise Resource Planning (ERP) software. It has also customer relationship management (CRM) and supply chain management (SCM) functions. It is in contrast to proprietary or most other open source ERP solutions driven only by a community of supporters.
2. Manufacturing – Plugin available manufacturing plugin , Plugin is available here
3. Use friendly web UI.
4. iDempiere supports:
   1. Multiple tenants
   2. Multiple organizations (branches, plants, etc.)
   3. Multiple languages (29 localizations; mixed access in a single installation is possible)
   4. Multiple currencies
   5. Multiple accounting schemas

Cost

As an integrator, I do not like dealing with selling software. I know of no customers that like ‘paying’ for software. Because iDempiere is free and open source, I get to specialize in what I do best – help customize iDempiere for specific needs.
