There are two different accepted pages available from your dashboard, "Sales" and "Purchases". After reviewing your invoices in your inbox, you can send the them to their respective pages.

This allows you to seperate the reviewed invoices from the incoming ones. When calculating tax returns, this is where your invoices will be pulled from. For more information, see Tax Returns.

Once you are completely finished with these invoices and wish to archive them, simply select the invoices and click the "Send to Archive" button. This will store your invoices, for as long as you need.

If you notice an error or wish to edit the invoices further, you must move the invoices back to your inbox and edit from there. This process is exactly the same as before. Select the invoices you wish to edit and click the "Send to Inbox" button.
