According to the Lake Saint Louis Comprehensive Annual Financial Report for the Fiscal Year Ended June 30, 2018,[10] the top employers in the city were:

When Schnucks opened a store on the city's previously undeveloped south side in 2004, at the intersection of I-64 and Lake Saint Louis Boulevard, it marked the beginning of a rapid retail and commercial growth for the city. This was the first new retail development the city had seen in 17 years. In addition to the Schnucks development, the National Information Solutions Cooperative (NISC) also announced plans to build its $18 million 135,000-square-foot headquarters near the same intersection in 2004. The initial commercial development of 2004 was soon followed by the development of two large retail districts in the city: The Shoppes at Hawk Ridge and The Meadows at Lake St. Louis. Prior to this period of current retail growth, the city had very little commercial development. Residents of the lakeside community traveled to nearby Wentzville or O'Fallon for most shopping, dining, and other service needs that were not previously available in the city.[11][12]

Bounded by I-64 to the north, South Fox Hound Drive to the east, and Hawk Ridge Trail to the South, the Shoppes at Hawk Ridge is an 800,000 sq ft (74,000 m2) retail development situated on the south side of Lake St. Louis. The development was spurred by the new $26 million Hwy N overpass completed in October 2005, which eventually became part of the Page Avenue extension. The development was the largest retail project in St. Charles County at the time of its construction, and it opened in January 2006. The Hawk Ridge development is anchored by St. Charles County's first Wal-Mart Supercenter, Lowe's, and numerous smaller retailers and restaurants. The Wal-Mart Supercenter was the most expensive store the company ever built, according to developer Don LaBrayere. Building styles and landscaping play a vital role in the look of the development. Businesses such as White Castle and Steak 'n Shake were forced to abandon their standard store designs and color schemes in order to comply with style elements of the development.[13]

The second major retail development that anchors the Lake St. Louis retail district is The Meadows at Lake St. Louis. Opened in August 2008, the Meadows is an open-air shopping district geared toward the community's affluent residents. The Meadows was developed to meet the growing demand for specialty stores and restaurants in St. Charles County, and it was billed as the first lifestyle center in the county. It features two landscaped boulevards in a downtown street grid, surrounded by 500,000 sq ft (46,000 m2) of restaurants and a variety of specialty retail stores. The retail portion of the development is anchored by upscale specialty department store Von Maur. Kansas City-based Ferguson Properties also plans to build a 110- to 120-room Marriott or Hilton branded hotel geared toward business travelers as part of the lifestyle center. The Meadows is located on 64 acres (26 ha) on the north side of I-64 near Lake St. Louis Boulevard.[14][15] In March 2012 the Meadows announced over the next 5 years, four more retail buildings and the addition of a Neiman Marcus or Saks Fifth Avenue. There are also plans that have been approved for a Hilton Hotel.
