All approved invoices will be posted to your finance system. The time it takes to do this is dependent on whether your application is on-premise, or cloud based. If your application is cloud based, posting will be instantaneous, if it's on-premise, it may take a little longer.
Navigate to your 'Approved' tray.
In the far-right column, the invoice has a journal ID attached to it. This means that your invoice has been posted.
In the unlikely event that a transaction fails to post, it will drop in to the 'Posting failures' tray. Two things will happen in this case:
1. The administrator will receive a notification to inform them of the failure.
2. The administrator will be able to load the transaction and see the failure on screen. They can then retry the posting, or return the invoice to the unprocessed tray to be further edited.
