Contracts are agreements between your company and another entity for bulk or custom orders. In some cases, they can be pivotal to the success or failure of your company.

The game offers several types of contracts with different requirements. You can find a basic tutorial on how to use the contract system on the Office page.

The game offers contracts that fall into three different customer types, all four design types, and variations therein.

See the Contracts Game Mechanics chapter for a more detailed breakdown of the formulas behind requirements and selection.

Military contracts are typically engine contracts for national governments. You'll design these engines for air, tank, and naval applications. Each application faces unique design challenges and can range from bulk orders to very high-priced niche orders.

Militaries can also order vehicles. Militaries will only order limited types of vehicles at this time. But they're often bulk orders and can be very profitable.

When nations go to war, military orders will increase both in terms of designs and volume. But you'll be limited to only supplying your HQ nation from factories located in your HQ. Military Contracts for your HQ nation are the only type of production not limited by conflicts in the game.

Civilian contracts can run the broad gamut of vehicle types and engine designs. These contracts can be for everything from local government vehicles, taxis, rentals, train engines, and home generators.

Most of these contracts are bulk orders, but they're unlikely to be renewed frequently, unlike military contracts. It's often wise to use your existing designs for these types of contracts.

Racing contracts focus on vehicle types used in racing and the components used in spec racing. When it comes to vehicle contracts, you'll get some credit for the success of the vehicles. However, for engine, gearbox, and chassis contracts, you will receive none. Racing contracts typically order very few units, but they pay more per unit.

When a racing contract goes unfilled, the teams or series can purchase designs from the open market. When this happens, they may purchase your designs, even though you have no associations with the team. There is no way to prevent this action since they are purchasing the designs as regular consumers.

Contract design requirements are listed on the right side of the contracts window. The game will color code these specifications if your design meets the requirements. Customers are looking for designs that meet or exceed their requirements. Therefore most of the specifications require higher numbers. But where logic dictates, the numbers should be lower. For example, your design's weight numbers should be lower than the requirement.

When accessing the Contracts system from the Research and Development room, the game will give the option to use the assisted designer for engines contracts.

Clicking the “Assisted Design Component” button from the contract window will open the Assisted Designer. The AI will also try to design a component that meets the requirement of the contract.

This system is only available for engine contracts.
