QuickBooks is an accounting software package developed and marketed by Intuit. First introduced in 1983, QuickBooks products are geared mainly toward small and medium-sized businesses and offer on-premises accounting applications as well as cloud-based versions that accept business payments, manage and pay bills, and payroll functions. History Intuit was founded in 1983 by Scott Cook and Tom Proulx in Mountain View, California, USA. After the success of its Quicken product for individual financial management, the company developed similar services for small business owners. Initial release The initial Quicken software did not function as a "double-entry" accounting package. The initial release of QuickBooks was the DOS version that was based on the Quicken codebase. The Windows and Mac versions shared a different codebase that was based on In-House Accountant, which Intuit had acquired. The software was popular among small business owners who had no formal accounting training. As such, the software soon claimed up to 85 percent of the US small business accounting software market. It continued to command the vast majority of this market as of 2013. Professional accountants, however, were not satisfied with early versions of the system, citing poor security controls, such as no audit trail, as well as non-conformity with traditional accounting standards. Subsequent releases Intuit sought to bridge the gap with these accounting professionals, eventually providing full audit trail capabilities, double-entry accounting functions and increased functions. By 2000, Intuit had developed Basic and Pro versions of the software and, in 2003, started offering industry-specific versions, with workflow processes and reports designed for each of these business types along with terminology associated with the trades. Options now include versions for manufacturers, wholesalers, professional service firms, contractors, non-profit entities and retailers, in addition to one specifically designed for professional accounting firms who service multiple small business clients. In May 2002 Intuit launched QuickBooks Enterprise Solutions for medium-sized businesses. In September 2005, QuickBooks had 74% of the market in the US. A June 19, 2008 Intuit Press Release said that as of March 2008, QuickBooks' share of retail units in the business accounting category reached 94.2 percent, according to NPD Group. It also says that more than 50,000 accountants, CPAs and independent business consultants are members of the QuickBooks ProAdvisor program. By then Brad Smith was the new CEO, though former CEO Steve Bennett had nearly tripled Intuit revenue and quadrupled earnings in eight years. On September 22, 2014,
