To answer this question, we have to understand the difference between Approved and Finished status in the Payments. A transaction appears as Approved when the risk has been analyzed and the transaction approved.

After approval, the amount of the transaction is settled. However, the status of the transaction does not then automatically change to Finished. For this to happen, the Tax Receipt for the order has to be entered in the Orders module.

After this has been done, the Orders module communicates with Payments, which alters the status to Finished.
