Gusto, Inc. is a company that provides payroll, benefits, and human resource management software for businesses based in the United States.

[6] On June 12, 2013, Gusto announced support for paying contract workers, including making sure of tax compliance (by filing the relevant Form 1099 and other paperwork).

This was touted by some technology writers as giving the company an advantage over competitors such as ADP and Paychex, whose payroll software was claimed to lack the flexibility to accommodate contract workers.

[7][8] In August 2013, Gusto announced that it had crossed $100 million in payments processed annually, and was launching in Florida, Texas, and Washington state.

[9] In September 2014, Gusto announced its application programming interface (API) and partnerships with over a dozen small and medium business (SMB) back-office service companies.

[13] In September 2015, it was announced that ZenPayroll had changed its name to Gusto, and was broadening its focus to integrate health benefits and workers' compensation into its payroll software.

[14] In 2016, the firm launched an ad campaign featuring Kristen Schaal playing a Gusto human resources representative.
