Although the GoBD (Principles for the proper management and storage of books, records and documents in electronic form and for data access) has already been included in the 1. January 2015 in force, but now the transition period ended. Since the 1. January 2017, all companies that have a minimum turnover of 17.000 Euro, are obliged to comply with this administrative regulation. This means that all electronically-generated data, ultimately having an impact on accounting, must meet GoBD requirements throughout the retention period. Not only the documents that directly affect financial accounting are affected, but also all records from ancillary and ancillary systems, such as payroll accounting, fixed asset accounting or enterprise resource planning. Also included is the data generated by electronic systems, including POS systems and cash registers or electronic scales.
