From In-Portal User Manual

Pending

The Pending tab displays all pending orders. These are submitted orders, which are pending payment authorization. There maybe credit card orders, for which the credit card has been authorized, but not charged; there also maybe manual payment orders, for example when the customer is paying by check or wire transfer. The administrator of the store has to verify that the payment has been received (or that the credit card order is valid), and Approve or Deny the order.
This section has the following action buttons in the toolbar:

• Edit – edits the selected orders (as with any other list in In-portal, you can edit multiple items at once). You can only edit the administrator comments at this stage.
• Clone – creates a complete copy of the order, but assigns it a new order number, resets the status to “Incomplete” and clears any shipping dates and payment receipt confirmations. This is very useful for re-ordering – creating new orders for the same products to the same customer, as well as modifying orders when they have already been processed – to do this, clone the order and deny the original.
• Approve – approves the order for further processing. For credit card orders, the payment is collected, and for other payment types, it is assumed that the payment has been collected. The order becomes approved for shipping, and attains the “To Ship” status.
• Deny – denies the order, setting its status to “Denied”. All order information is left as-is, however when an order is denied, you can only archive it. Such order cannot be approved, shipped or processed any more.
• Print – prints the order invoice.
