Order Statuses in WooCommerce:

• Pending: Order received, awaiting payment.
• Processing: Payment received and the stock has been reduced; the order is awaiting fulfillment.
• On hold: Awaiting payment – stock is reduced but the order needs confirmation.
• Completed: Order fulfilled and complete – no further action is required.
• Cancelled: Cancelled by an admin or the customer – no further action is required.
• Refunded: Refunded by an admin – no further action is required.
• Failed: Payment failed or was declined (unpaid).
