Its headquarters, offices and factory are all situated in the town, close to Legoland. Historically the prosperity of the town has been closely tied with the success of the company. When Godtfred Kirk Christiansen took over The Lego Group as managing director in 1957 due to his father's illness, the company experienced continued international and economic growth over several decades. Employment at the company grew from approximately 200 in 1960 to 1,000 in 1970, 3,000 in 1980, 7,000 in 1990 and 9,000 in the mid-1990s with half of employees living in Billund and the other half internationally. By 2022, the company employed 20,000 people, with over a quarter being employed in Billund.

In 2010, Billund was ranked as the top place in Denmark with the highest employment in the experience industries (27.3%). One in four people (25.9%) living in the municipality worked in the traditional tourism industry, particularly in local attractions such as Lego, Legoland, Lalandia and Givskud Zoo. Only 1.4% were employed in the creative industries. Transport Billund is served by Billund Airport, which is the second largest airport in Denmark after Copenhagen.

In 1964, the ownership of the airfield was transferred to Billund Airport A.m.b.A. When it opened to the public in 1964, it comprised an old hangar, a runway of 1,660 metres in length and a single control tower. In its early years, the airport served approximately 4,000 passengers with only two domestic departures per day. Since then, Billund Airport has experienced major growth and now serves
