In Substly, you can easily add financial data using a file import. This is especially helpful when you want to get an overview of actual costs by importing data from your accounting system. The most common format for this is a SIE file.
What is an SIE file?
SIE (Standard Import Export) is a standardized Swedish file format used to securely and efficiently transfer financial data between different systems — for example, exporting accounting data from your financial software and importing it into another tool like Substly. SIE files are widely supported by most Swedish accounting systems, making them a convenient and reliable way to transfer financial data for analysis and tracking.

File Requirements
Things to keep in mind:
File format: The exported file must be in SIE type 4 or 4i format. When you export it, it should have the ending .sie or .se
File size: To ensure smooth processing, uploaded files must not exceed 10 MB. The system will not handle files larger than this limit, and an error will occur. What to do if your file is too large: If it is over 10 MB, we recommend splitting it into smaller parts. Depending on the file type, you can do this using a spreadsheet tool (like Excel or Google Sheets) or a text editor.
Time period: The system analyzes historical data to forecast future spending. For the most accurate predictions, select a more extended time period— at least 12 months to capture all annual payments, and preferably 24 months for best accuracy.
Only one SIE file can be imported at a time. Before uploading, make sure each file is under 10 MB and upload them once at a time.
Double-check the information: After importing the file, review the data to ensure accuracy and select which suppliers you want to add to your Substly account. If you experience issues exporting SIE-files, contact your accounting system’s support to verify the export.
💡 Tip
After importing your financial data, go to your Dashboard or Approved Services overview in Substly to see how the actual costs align with your expected spending. This will give you a clearer picture of where your money is going.
