Single Administrative Document (SAD)


AEP & AIS are Revenue systems that allow for the completion of Customs-related procedures in an electronic format.

The automation of Customs import and export procedures was introduced nationally in April 1991 by the launch of Revenue's Automated Entry Processing (AEP) system. Since then this system has been responsible for the validation, processing, duty accounting and clearance of customs declarations. The system also checks updated data formats, calculations, validations, preferential rates, prohibitions / restrictions and verifies that sufficient credit is available in the Trader's account.

Revenue will implement a new national import system on Monday, 23 November 2020 at 9:00am. This new Automated Import System (AIS) has been introduced to comply with the provisions of the Union Customs Code (UCC). AIS will ensure that businesses can import goods legally from outside the EU using the most efficient process possible.

Due to the introduction, by European Regulation, of a harmonised and codified Single Administrative Document (SAD) the AEP system was redeveloped by Revenue. Since completion of the redevelopment project, traders now have direct access to AEP via the Revenue Online Service (ROS) and greater scope for flexibility and trader facilitations. From 23 November 2020 AIS will also be accessible via the Revenue Online Service (ROS).
