Automate time-consuming and tedious tasks with Cosuno AI
Calculate prices in line with market standards using AI
Calculating bids for tenders can be a time-consuming and risky task without reliable comparative data.
The Cosuno Price Assistant uses AI specifically trained with tender data to deliver accurate price forecasts for your specifications. Semantic text matching provides you with comparative prices from your own previous tenders. This allows you to calculate precisely, remain competitive, and always have market-based comparative prices readily available for your negotiations.
Intelligent tendering
The traditional tendering process requires tedious preparation, extensive manual follow-up, and often involves hidden costs.
Cosuno's AI identifies potential risk factors as early as the specification stage, helping you prepare your tender in the best possible way. Centralized submission, easy monitoring of incoming bids, and automatic price comparisons save your procurement team time on follow-up, freeing them up to focus on what matters most.
Efficient partner search
The Cosuno network gives you access to over 250,000 qualified subcontractors, planners, and architects. Synchronize your existing contacts to manage all partners centrally.
Based on your project criteria and historical bid history, Cosuno's AI recommends suitable bidders. Additionally, you can inform companies seeking projects about your current projects on the Cosuno marketplace. This way, you secure the best offers without tedious searching.

We quickly realized that sending the bills of quantities to bidders is particularly easy. Simply create a project and provide a brief description, upload the bills of quantities, documents, plans, etc., create a bidder list, and you're ready to go. Cosuno makes this significantly faster than before.
