We dispatch our goods using a 3rd party fulfillment company and have a sales order export module which fires over all orders with the status of Processing.
We currently accept card payments with a card facilitator using their hosted form, and when payment has gone through successfully the order is given the status of Pending. We can then manually change this to Processing when we're confident the order is fully in stock and good to go.
When customers pay via PayPal Express, the order is automatically given the status of Processing.
How can I change this to Pending?
