The Archive folder is where all previously processed and published invoices are stored. The invoices can be viewed and downloaded just like the Inbox but they are not editable from within the archive folder as it represents the details that were published to your accounts package.
An invoice can be unpublished by clicking on the green 'Published' tick to the left.
This transfers the invoice back to the inbox where it can be edited if required before publishing again.
NOTE: While you can unpublish an invoice in AutoEntry, it DOES NOT remove the invoice from your accounting package. This must be done manually before publishing the invoice again in AutoEntry.d
