  • Accept or reject with a single click

    With a single click, you can directly indicate in the inquiry e-mail whether you would like to submit a bid or not. As a result, you and all the stakeholders involved save unnecessary inquiries by e-mail or phone.

  • All ongoing bids constantly at a glance

    Instantly see the bids you have submitted for a particular trade. Supplements can be easily created and tracked later. Everyone involved never loses track of the current bid.

  • Fill out the bill of quantities online

    Simply fill out bills of quantities online. It is no longer necessary to print bills of quantities and scan bids and the client does not have to manually digitise your bid again. As a result, both parties save a lot of time.

  • Automatic calculation of sums

    By entering unit prices digitally, we calculate the totals automatically. As a result, you no longer have to calculate totals and page transfers yourself. This saves time and avoids errors.

  • GAEB import

    We support GAEB format, allowing you to download bills of quantities, price them in the AVA tool of your choice, and conveniently upload them to Cosuno.

  • All documents in one place

    Especially for larger projects, a smooth exchange of documents or plans is necessary. For this purpose, Cosuno has a central file repository for each request and bid. This enables all parties involved to find the appropriate documents at one place.

  • Direct contact

    If you have questions about an inquiry, you can contact the client directly via the message function. As a result, your message will be sent directly to the appropriate contact person in the case of technical questions. As soon as an answer is available, you will receive a notification.

  • Simply submit your certificates

    Clients may request certificates from you using Cosuno. Once submitted, they do not have to be uploaded again for each new trade.
