When Beija-Flor Jeans started outgrowing its Intuit QuickBook software last year, the company started looking around for something more robust to help mange its growing accounting, CRM and inventory management needs.But rather than spend big bucks on a commercial enterprise resource planning suite, the company decided to try open source technology from OpenERP, a relatively little known vendor based in Belgium.Six months later, it's a move that appears to have paid off, says co-founder Kathy Moca, president and co-founder of Beija-Flor, a small business that supplies Brazilian-made jeans to about 300 boutique stores in the U.S."It cost us less than half of what it would have cost if we had gone with a commercial solution," she said. And it has been much easier to customize and mold OpenERP to their needs than it would have been possible with a commercial product, she said.
