fmOrders - Order Management Section
At the moment Magento order management section allows you to
view and filter orders, delete orders, export order data and manage orders. More functionality will be added further.
Let's go over the most important moments of Magento orders management, see product subpages for details:
Main orders section is described below.
Orders Section displays all your orders and their information in
tables. Filter option is actually the one that is responsible for the
orders' view on the page. If you'd like to display the orders that meet
some specific time requirements only, please select the time period at
the right side of the page and hit Apply button.
You can find more information about any order at the bottom.

Information Tab
This tab shows you detailed information for current order, like:
ordered products, their price and quantity, payment information, order
totals and order details.
Invoices
This section shows you invoice list. At the moment it allows you to preview invoices only. More options will be available later.
This is a record of the receipt of payment for an Order (in some
cases, payment can actually be automatically received simultaneously
during the creation of an Invoice), thereby essentially making it a
permanent record of an Order. Multiple Invoices can be created per
Order, containing as much or little of the purchased item quantity as
you desire. However, each unit of each item can only be invoiced one
time, so there is a finite limit to the number of Invoices that can be
created. Because this is a permanent record of the Order, all quantity
that has been Invoiced can no longer be canceled.
Credit Memos
This is a record of a refund. An item cannot be refunded until it is
paid (as in an Invoice), so you will not be able to create a Credit Memo
until an Invoice has been created. While it is a record of a refund, it
is not a record of a return (the actual returning of funds to the
customer). In some cases, a return can be given simultaneously during
the creation of a Credit Memo (just as a payment is with an Invoice),
but it is not a necessary part.
Shipments
This is a record of the items in an Order which have been shipped.
Like an Invoice, Multiple Shipments can be created per Order, with a
finite limit.
Comments history
Here you can find a list of order comments. To help you manage
Magento orders Order Comments can be added while creating an order, also
they can be added to completed Orders. Also here you can see whether a
customer was notified or not.
