When you want to transfer information to an accounting system we haven't integrated to, you have the option of downloading an SIE file. You will however require configured Accounting Data.
When this is done, do the following.
In Backoffice, click Reports and choose Z Report.
Pick a period and then click Show Report.
At the top of the report you'll find the options Email Report, Print and Download SIE File, pick Download SIE File. If your accounting data is correct for this period you will download the file. You can now send it to your bookkeeper. They will be able to load the file in their accounting software without manual handling.
