The software meets the requirements regarding the Public Procurement Code. Very good reactivity of the Hot Line team. For the projects managers as the engineers , there is a good view of the whole contrats of the project, with an easy access to all the details of every contract. All the market developments and situations are completely tracked. The electronic invoices with online validation allows to avoid any delays due to postal delivery. The possibility of having two situations in the same time in the validation process is a valuable asset. Good ergonomy.
