I use authorize.net which is set to authorize only. When someone places an order it comes into the admin area orders with the status set as processed. Is there a way that by default they would come in as order status open?
Unfortunately this is hard-wired into the outer “process payment” functionality and is not dependent upon the setup for the payment provider. The correct way would be to have it have a status of Authorized when an AUTH is done and then to also allow you to CAPTURE the previously authorized transaction and have the order status then changed to Processed.
