Once you have imported all verification attachments and customer and supplier invoices into Boardeaser, you can double-check that everything has been imported.
You can access a table or the dashboard. Then click one of the sums, and a small pop-up will appear. Click on the "Drill Down" option.

Now, you should see the attachment with you.
