On the Cosuno platform, you can see all bid requests and the appropriate message histories with construction partners and stakeholders. A transparent overview of all messages will help you to manage all bid requests in more efficient ways.

Share bid requests

With just one click, you can share bid requests with your construction partners. Monitor and keep a clear overview of all incoming and outgoing responses for a faster collaboration between all parties.


The Cosuno platform enables you to keep all communication for the complete tendering process in one place. Monitor messages by using the built-in messaging function. This way, communication and collaboration between all involved parties are easy and fast.

Send invoices and get paid earlier

Invoice management

Our platform enables a more convenient and efficient way for your invoice management. Create and send out invoices to receive payments quicker, keep track of their current status, and get paid on time. If payment problems occur or you notice discrepancies in payments you have received, you can take immediate action and contact the appropriate construction partner.


With Cosuno, you will receive your payments earlier and won’t have to wait long periods. Send your invoice to your construction partner and get paid directly after a completed project. To have more control and a better overview of all transactions, you can keep track of their current status.


You can handle all addenda for every project directly on the Cosuno platform and receive updates about their status. Construction partners will be informed about these changes immediately after you publish them and can react right away.


"Once we booked a demo with Cosuno, we immediately realised that the software was what we needed. Within three days, we were able to manage the entire manual tendering and awarding process online with the Cosuno software."
