Track all your projects in one place and save valuable time

You can manage the entire procurement process more simply and efficiently on our platform. Let your procurement managers focus on the crucial tasks while we help you to save time: improve your processes and keep all your projects in one place.

Cost calculation

Thanks to our platform it is easier for you to plan your projects. Easily determine your project costs with DIN 276 and BIM and have all project data in one place.

BoQ creation

You can create your bill of quantities and directly inform all bidders over the platform in case you had to make changes afterwards. Benefit from real-time tracking of all bid responses and use only one tool for direct outreach to subcontractors.

Material procurement

The price comparison table allows you to always select the right offer for your construction projects. It provides you with a clear overview over all costs and prices at any time during the bid negotiations. Additionally, keeping all manufacturers in one place helps to simplify all processes even more.

Achieve higher bid response rates and find suitable bidders

Cosuno will help you to receive not only more bids but the right ones for your projects.

Subcontractor network

Having access to our comprehensive subcontractor network allows you to expand your own and lets you benefit from receiving recommendations entirely based on your personal tendering activity. Once you have found a right subcontractor you can (easily) get access to their credit score.

Price comparison table

Cosuno enables you to compare all bids directly on the platform for a clear overview. Handling all negotiations on our platform simplifies communication, allows an easier price comparison and helps you to make better decisions when it comes to choosing your construction partners.


Our platform helps you to manage your documents for all construction projects in more efficient ways. By keeping all your records digital you can eliminate paper work and save money and time. Additionally, construction partners can sign their contracts directly on the platform and you can track the current status of each document during the ongoing process.

Optimize your invoicing process

Pay subcontractors on time and keep a complete overview of your finances in one place.

Invoice review

Having full control over your invoices allows you to perform reviews or amendments directly on our platform. Having a person in charge for all invoicing processes will help you to release invoices easier and pay your subcontractors quicker. Tracking the current status of each invoice ensures that you stay up-to-date throughout the whole payment process.


If a subcontractor makes changes on their side you will be directly notified on the Cosuno platform. You can review addendums which were added afterwards, approve them or reach out directly to the appropriate subcontractor if you have any questions or concerns.
