The Order Completion wizard is a sequential set of steps to guide a photographer
through completing an order and uploading it directly or saving it to media to
be delivered physically.
The first step is to select the manner of delivery:

Send now via the
Internet will upload the order file directly to the lab's servers for
processing. While uploading immediately sent orders, other orders can't be
created or manipulated. If a user wishes to upload and create orders at the same
time, use the next completion option.
Save for sending later via the
Internet will queue the file to be uploaded later. To see and upload the
queued orders, use the "Show Queued Orders..." from the main window's "Open
& Save" menu. While uploading queued orders, other orders can be created and
manipulated.

The top
area of the Queue Window shows the orders queued for sending. Select one or more
of these and hit "Send" to start doing so. To remove them from the queue, click
the "Remove" button. Note that this does not delete the order, it simply moves
them out of the queue to the order history area.
The order history area
shows past orders. These orders are kept in the preference folder for the length
of time specified in the "Days to backup orders" preference.
Save to disk
for alternate delivery simply saves the order file to a location specified
by the user, so it can be burned to CD or DVD for some other delivery method.
Orders which are saved to an alternate location aren't kept in the order history
area.
The second step is to select the manner of payment:

These will differ
based on what the lab has configured, but the common methods of payment are
described below.
Credit Card shows entry fields for credit card
information. This information is encrypted with the order for safe transmission
over the Internet or via recorded media.

Use the "Save for
future orders" to save an encrypted file in the preferences folder which
contains your payment information.
PayPal instant payment will
open a browser window so you may pay for the order immediately using PayPal to a
lab's PayPal account. While the browser window is open, a notification window is
shown. When order payment is complete, the method of delivery selected in Step 1
will be done.
Charge to lab account/Other simply marks the
order as having not yet been paid for, and performs the delivery method
selected.
The next step is carried out by the application, which is
performing the order delivery method selected in Step 1. The order is first
compressed and encrypted for ease of handling and security.

If the selected
delivery method is to send immediately, then the application communicates with
the lab servers and begins transfer.

If
the transfer is cancelled, the order file is moved to the queued folder for
sending later.
The order is complete! Other orders can be created or
changed, or the application can be safely quit.
