Cosuno

Cosuno operates a cloud-based software-as-a-service platform for tendering and awarding construction services (Ausschreibung und Vergabe). It targets the phases of construction procurement in which general contractors, project developers, property developers and architects solicit, compare and award bids from subcontractors. The platform lets users create a tender, upload bills of quantities (Leistungsverzeichnis), plans and documents, assemble a bidder list and dispatch the request centrally instead of sending large numbers of individual emails; incoming bids are tracked automatically and compared in a price-comparison view (Preisspiegel). The company describes its positioning as making "200 emails into 3 clicks" [2][4][5].

The product suite spans tender creation and award (AI-supported creation and analysis of specifications, central bid dispatch, digital bid submission, automatic price comparison, digital award and rejection), documents and contracts (cloud document storage, digital evidence management, contract conclusion, change-order management), project control and communication (collaboration, task management, dashboards, bidder communication), master data, ratings and qualification of partners, and costing/controlling (quantity determination, cost calculation, a historical price database, AI market prices and award success analysis). A marketplace component allows buyers to publish bid packages publicly so that contractors searching for work can find and respond to them, and a subcontractor directory lists specialist firms by trade, region and company size [0][1][2].

Alongside its own network, Cosuno positions itself as compatible with common AVA tools, supporting GAEB file import and export by drag and drop, and offers integrations with SAP, RIB iTWO, Nevaris Build and BRZ. The company states its software is certified [2][4][5].
