Assign Bitizens to jobs they are skilled at to get faster restocking. Bitizens will constantly ask you to operate the elevator. If you have the time to do so, you will earn extra Imperial Credits. The elevator can be upgraded to move faster, but this requires Imperial Bux. Up to three Bitizens can work on a level, and each of them is responsible for stocking a specific item. Low-tier items are stocked quickly, sell quickly, but do not earn a large amount of Imperial Credits. Higher-tier items require more time to stock, but appear in higher numbers and can earn more Imperial Credits. Every Bitizen has a dream job. When assigned to a dream job, you will be able to order twice as much of the stock that particular Bitizen sells.
