eInvoicing in Bulgaria is based on bilateral agreements between economic operators (or solution providers acting on their behalf) and public administrations.  

According to the practice of the Commission for Protection of Competition, resolutions for termination of a procedure with participants are served only through CAIS EPP. Article 9k, paragraph 1 of the the Regulation for the Implementation of the Public Procurement Act states  states that the exchange of documents and communications between contracting authorities, candidates, participants and contractors is carried out through the platform.  

CAIS EPP notifies the participants of new publications in the Buyer’s Profile about the procedures in which they participate. 

It is specified that according to Article 9k, paragraph 3 of the Regulation for the Implementation of the the Public Procurement Act, the users of the platform are obliged to monitor their profiles for notifications, messages and documents. CAIS EPP also notifies the participants of new publications in the Buyer’s Profile about the procedures in which they participate.
