Yeah, but y'all left out the BSing, feeding the dogs, letting out the chickens... :-D
Just to add my thoughts on this: Cut outs can be done in the morning, even finished in entirety well before dark but if you don't leave the new set up there and seal it in the dark you will leave behind quite a many bees which the customer will not be happy with. Besides the colony could likely use those extras that are out foraging.
If the situation presents itself I don't have a problem leaving the new set up on site for a few days to several days then picking it up another night. An added benefit to leaving it there also allows the bees to clean up any spilled honey. Just to add, its important when leaving a hive that either the queen has been caged, the void space sealed so they can't go back in or the area sprayed down heavy with something like beee quick.
