Despite the shaky economy, now is a good time to keep ahead of your competitors by offering products or services that they don't. Buying permission to manufacture and sell (or licensing) a product from the product developer or supplier can give your business the diversity it needs to stay competitive. The primary advantage to precasters who choose to license a system is that the licensor often provides the materials and expertise to help them get started. The license fee usually includes equipment, training and technical support, marketing assistance, and brochures and other promotional material. Some examples of products available for license are: precast furnishings, erosion control mats, retaining wall systems, and tunnel systems.
