uniTender is a venture based on the vision that every small, medium or large enterprise should optimize its procurement processes using supplier auctions. Large Corporations have their own reverse auction platforms operated by their own IT departments, but small and medium enterprises have little access to auction platforms. uniTender believes that every SME should use reverse auctions to negotiate with their suppliers. Some specialized auction platforms exist, but auction setup is customized (slow) and auction costs are not affordable to SME's (over USD 1000 / EUR 1000 per auction). We believe that with intensive investment on a new technologic approach, based only on standard technologies, it is possible to offer affordable auctions, with similar or better quality than public tendering platforms. The uniTender concept arised from the founders experience with public sector e-procurement platforms, working with public sector suppliers organizations. These platforms yield excelent results, but most of the processes are fit to the public sector burocratic model.
