If you have admin access, you can manually close at anytime from Closeout app  or Orders app . If you are on autoclose, your autoclose time will still process at its designated time.
NOTE
If you are manually closing out Closeout app , you will be prompted to enter tips for all transactions without designated tips. If you are manually closing out from Orders app  (only available to merchants on Pro plan), you will not need to designate tips for any order.
