Documents
Every document that has been created for you: orders, delivery notes, invoices. The columns are called Document number, File name — with the kind of document above it —, Recipient and Created; the button at the end of the row downloads the file.
The list is newest first. If you are looking for a particular document, go by the document number — the file name on its own says little. For older documents not every detail can still be determined; there it says not determinable.
The yearly export packages are not here
They have an area of their own: Export.
This area is one of sixteen under Settings. How they fit together and in which order to set them up is on the Settings page.
