Apprende has just released updates to the order process.

Create an order from a user's profile
You can now initiate a new order directly from the user's profile. Visit the Orders tab within the user's profile to see the new Create Order button.

Streamlined Create Order Process
The choice of creating an order or an invoice has been removed.  You will now be presented with only one option, Create Order, and will have the opportunity to apply payment or save an open order.

Edit Open and Incomplete Orders
You may now add and remove line items to orders in Open or Incomplete status.
