Transportation is taken care of by a 3rd party transportation company. This company takes care of the transportation between your company, an airfield, additional handling and the transportation from the airfield to your customer. For handling and transportation you pay a price, of course.

When you want to buy a number of products, e.g. 20 PC's, you'll send a request for quote to one or more suppliers. As a result, you'll receive a number of quotes. In each of these quotes, a part of the proposed price is for transportation. These costs are calculated on the weight of the product, the requested amount and the region and distance to the supplier. When you pay a bill, the costs for transportation are diverted to the 3rd party transportation company.

When you send a quote to one of your markets, the transportation costs are added to your quote automatically. However, you're able to see these costs when you send a quote. When a payment is received from one of your markets, the transportation costs are diverted to the 3rd party transportation company.

As you can see, the transportation company takes care of all the handling and transportation involved with your shipments. For case specific costs used in your game, please check the case description, e.g. Local vs. Global.
