List of top open source ERP free solutions

A friend recently asked if I know of any open source ERP free solutions for him to recommend to his IT department.

During these uncertain times, many organizations are holding back on IT spending causing some software vendor shares to slide on early warnings.

Companies such as SAP, headquartered in Waldorf Germany have indicated that the recent financial crisis has affected their ability to sign contracts as many customers put IT investments on hold. This illustrates how dramatically enterprise application spending has dipped in just a few weeks.

Most organizations feel that to implement an ERP solution, the cost is usually very high, tedious, and requires a lot of time and effort to put in. At these times, most organizations may be looking for alternative software solutions which are:

  • Lower in cost
  • Flexible in many ways
  • Having a large group of users
  • Not dependant on the solution provider

Why is having inventory management solution so important for your business?

To counter the drawbacks mentioned above, Open Source ERP solutions may be the answer. With Open Source ERP solutions, companies can download the solutions and customize it based on business requirements that fit the company’s business flow and processes. Most times, implementors and users of these solutions are only bound to the type of licensing model that the ERP solution is released under.

If your organization is planning to implement an ERP solution which best fits the business processes within the organization, the following are a list of Open Source ERP solution to evaluate and implement:
