When you've sent an order, mark it as Shipped. When the customer has collected it, mark it as Picked Up. This moves the order from Unfulfilled to Fulfilled and takes it off the green number beside Orders.
How to mark one order as shipped
Go to Orders and click the order number to open the order panel.
Click Mark as Shipped. For a pick up order, the button is Mark as Picked Up.
The confirm pop-up asks "Are you sure this order has been shipped?". The Send notification email to customer box is ticked. Untick Send notification email to customer if you don't want to email the customer.
Click Yes.
The order now shows Fulfilled and a Fulfillment Date. If you left Send notification email to customer ticked, the customer gets an email saying their order is on its way.
How to mark many orders as shipped or picked up
Go to Orders. Filter the list to the orders you've sent, or tick them.
Click Mark as Shipped or Mark as Picked Up. The number on the button is how many orders it applies to.
Confirm.
How to undo Mark as Shipped (revert the status)
If you marked an order as shipped or picked up by mistake:
Open the order panel.
Click Revert Fulfillment Status.
Click OK to confirm.
The order goes back to Unfulfilled, and the Mark as Shipped button is back. If the customer already got a shipped email, let them know about the mistake yourself.
How to send a pick up reminder
For pick up orders, click Send Pick Up Reminder on the Orders screen to email customers that their order is ready to collect. See "How to send a pick up reminder".
