I have completed my very first order without making any custom order for my client due to lack of knowingness. Only for the payment purpose I made a custom order where the delivery time I mentioned 20 days (amount of days the order took me to complete). although the payment has been made but the order on which the payment has been made keeps on displaying the delivery time (20 days ) for the order I have already completed. My manage sales section of my account keeps on showing no orders completed. Can someone tell me How can I mark my order as complete.
P: I expiration date of order is 3 days
