Our team just introduced a new feature in the document detail which opens the preview of the original invoice in a separate window!
Open your invoice and you will find it on the upper right corner.
To stop the preview from opening up, click on the "Close pop-out" button.
This way, you can easily review the line items without loosing the preview of the original document. Once you finish reviewing your invoice and move to the next one, the pop out window automatically disappears .
Imagine the difference when you review a document with tens of line items!
