Kansas City barbeques are famous, tasty, but not so easy to start. Because Kansas City sits on four different counties, licensing and permitting is extraordinarily complex. Many businesses - particularly those selling food, alcohol or producing hazardous waste - often require city, county and state licenses. Depending on the area of Kansas City in which a business operates, the licensing requirements can vary widely. As a result, city officials have a very difficult time advising entrepreneurs and a small business owner can easily find him or herself in a quandary. Although at one time, the cattle trade, agriculture and river transportation were once the dominant industries of Kansas City, today the city has a diverse economy. Kansas City is now home to major companies in communications, food, manufacturing, agriculture, restaurant and greeting card industries.
