Email threads and spreadsheets used to run construction tenders. We built Tenderix to replace both.
It's a reverse-auction platform. The admin builds each tender as a table — work items down the side, cost columns across — and sets a minimum bid step per column. Suppliers type offers straight into the cells, and every new bid has to come in lower than the last one by at least that step. So the price only moves one way.
Everyone sees the leading number. Nobody sees who's behind it until the admin picks a winner — and the pick can weigh delivery term and qualification alongside price.
Two portals (admin and supplier), light and dark themes, and the same bidding table working down to a 320px phone screen. Design and development by WebDesignSun on React and Node.
