Once a lab has sent you an offer for your request, you can view it on your dashboard. Go to the detail view of the corresponding request and click on "View offer" or "Place order".
This will open a window in which you can view the offer or accept it and directly mandate the lab. In addition, you can add an order number, an order document and a message, which are then transmitted to the commissioned lab.
All other requested labs are informed that another lab has been selected for the project. The requests to these labs will be canceled.
