At first blush, Scott Rosa\u2019s experience parallels that of other successful open-source ERP adopters. But the path to success wasn\u2019t straight. The CTO of Prevention Partners, which manufactures and distributes posters, buttons and other health-related signage, says his company outgrew its vertical-market, Windows-based ERP system. So Rosa hired a consultant to customize the Open For Business open-source ERP software for his firm\u2019s distribution arm.But the project management spun out of control, causing the effort to go over budget. First problem: The consultant had no experience with Open For Business, and its learning curve was steeper than expected. Second problem: Because Open For Business is very customizable, both Prevention Partners and its consultant \u201cgot caught up\u201d in much customization, Rosa recalls. And Open For Business is based on Java, which Rosa\u2019s developers aren\u2019t experienced in, so they couldn\u2019t take over.But Rosa didn\u2019t move back to a commercial product. Instead, he adopted the WebERP open-source software to develop a custom version for his company\u2019s manufacturing arm, which needed a quick and easily deployed ERP solution. WebERP uses the PHP language, which his developers know, and Rosa can manage directly. He plans on completing the Open For Business\u2013based ERP effort as well. \u201cI\u2019ve got the code. I just need to find someone to finish it for us. I would not buy a proprietary solution,\u201d Rosa says. Ultimately, Rosa plans to migrate one business to the other\u2019s ERP, but he hasn\u2019t decided which of the two open-source options will prevail.
