Rule to complete checkout for all orders How can I create a rule to process checkout for all orders. Te be more specific: I'm creating a shop in which the whole checkout is based on a cronjob. So customers add their products to the shopping cart and every week at friday a cronjob is processed to process all shopping carts and create a order for them. Payment is not necessary, and users can not manually complete orders.

I've tried to create this in rules, but their is only the option to "Complete checkout for an order" not all orders.
There is no default Commerce rules action that selects all orders. You're going to have to build your own action, or find a contrib module that provides it for you, that selects such a list of commerce orders to act upon.
