Your corporations do not produce a profit. As a result, the enterprise is losing money instead of making some. Corporations make profits if they produce at full capacity and sell all their products. Make sure you increase production levels and hiring and mainly, make sure you sell the products in direct contracts or on the market. If there is a surplus of products on the market, you may decide to reduce your prices or increase your quality. If your products remain unsold, you will not be able to make a profit. You can make an automatic connection between the quality of your products and the price you sell them for. This will automatically update your pricing to the current quality of your products.
