The BII workshop has developed a set of profiles to support interoperability in the pre- and post-award areas. The scope of BII is public procurement but the profiles apply as well to private trade since many private customers use tendering as good business practice. In those cases official Notification of calls and contracts is often not applicable. The scope of BII pre-award profiles include processes that support communication of notices on the procedures, calls for tenders with and without catalogue requests, tenders with and without catalogues and qualifications contract notices. During these processes additional information need to be exchanged between contracting bodies and economic operators, such as questions and answers and documents supporting a virtual company dossier.
