The "documents" tab contains all invoices, credit notes and reminders that are no longer in the outbox and therefore have already been sent to the customer.
You can download all documents individually by clicking on the PDF symbol or bundled as a .zip file. You can specify individual date ranges to download the invoices.
Also you can review the invoice by clicking on the document number, afterwards you can press the "Perform Action" symbol to download or correct the invoice.
In the "Reminders" section you can view reminders sent out to your customers. You can also filter and download them according to the respective reminder level and date.
