Leave space for flooring!
If the kitchen flooring is going to be hardwood or tile, and you’re installing it after the cabinets, you’ll have to raise the cabinets off the floor or the dishwasher won’t fit under the countertop. Use blocks to represent the finished floor height, and add those distances to the guideline for the base cabinet tops. Hold the blocks back a bit from the front so the flooring can tuck underneath. Your flooring guys will love you for this.
