The SIE file format

The SIE format is an open standard for transferring accounting data between different softwares by different software vendors. SIE could be used to transfer data between on-premises softwares as well as Apis. Due to the fact that the SIE standard is so widely adopted in the software business in Sweden it has become a de facto standard for transferring accounting data. The format is open to everyone, but only SIE members can get their software approved.

Different SIE-format types

  • Type 1, Year end balance. Contains opening and closing balance for all accounts in the chart of account
  • Type 2, Period balance. The same content as in type 1 and in addition balance change per month for each account.
  • Type 3, Profit centre. The same content as in type 2 in addition balance for different profit centers.
  • Type 4, Transactions. The same content as in type 3 in addition all vouchers in the accounting year.
  • Type 4i, Transactions. Only vouchers. The purpose of this format is to make it possible to produce vouchers for different support systems and then import them in the accounting system, e g wage software or invoicing software.
