The world of enterprise resource planning (ERP) has in turn been overwhelmed by open source solutions that have now reached maturity.
Open source ERPs initially provided small SMEs with complete management tools at the lowest cost, thereby rapidly stepping up their competitiveness. But these solutions are already climbing the ladder, currently targeting SMEs with staff of more than 1000, in the industrial, distribution and services sectors.
Because the playing field is so vast, differences in functional cover can turn a product more toward a particular sector of activities. But one of the most important selection criteria is flexibility/expandability, in other words the technological bases that will allow a given product to be adapted to a variety of different contexts with a limited number of custom developments.
Products like Compiere, OpenERP, Openbravo and ERP5 set the bar for open source ERPs.
