SIE is a universal data format to exchange accounting information between different systems.

Our auditor prefer having a SIE4 file, which he would import into his own system, to do the final revision and making necessary documentation for the government. W/o this file he has to tap in the data manually, which takes more time and cost us more money.

We would like to add the SIE file format as an alternative for export.
