Linked chests allow automated systems to interface with company products. There are four types: Restock, Recall, Buy, and Sell. They act the same way as the player command work.

• Restock: Any items that go into the chest are put into the company's product holdings
• Recall: A specified number of a specific item are kept in the chest. If the number of items in the chest goes below the specified number, items are pulled from the company's holdings.
• Sell: Just like restock for the target company, except the selected company gets paid the sell price of the product
• Buy: Just like recall, except the selected company pays the buy price of the product
