Well, if the customer puts down some fertilizer and if the rain (or snow) comes....most of the yard will come back.
The dry/dead areas may not, but that's where seeding/compost spreading/or slit seeding come into play.
It depends on what the customer is willing to spend and how much they care about their yard.
