Gusto buys Mosey to boost small-business compliance
Gusto has acquired business compliance platform Mosey, extending its reach into compliance management for small employers.
Mosey's tools cover HR, payroll, tax and corporate registration compliance for companies with remote, multi-state or international workers. Gusto plans to integrate the business into its existing platform for the more than 400,000 small businesses that use its software to hire and pay staff.
The move comes as small employers face rising compliance burdens across US states and local jurisdictions. Figures cited by Gusto show that one in three small businesses is fined for compliance violations each year, while companies with fewer than 50 employees face compliance costs of about USD $14,700 per employee annually.
Rising burden
That burden often increases as employers expand into new states. A single hire can trigger new unemployment insurance registrations, workers' compensation requirements, paid leave obligations and tax filings across multiple agencies. Separate rules on workplace notices, retirement plans and local policies add further complexity.
The combined business aims to handle registrations, filings, renewals, and other ongoing obligations in a single system. This would eliminate the need for a separate compliance tool and allow businesses to manage payroll and related compliance tasks on the same platform.
Gusto also highlighted the pace of legislative change. Roughly 15,000 new laws are passed each year across all levels of government in the US, creating a compliance environment that smaller firms may struggle to track without dedicated legal or finance teams.
Mosey was founded by Alex Kehayias, who previously started several businesses and has spoken about his own difficulties with payroll setup, tax deadlines and legal advice. Gusto said those challenges reflected a wider problem among founders who struggle to understand what is required after incorporation and during early hiring.
Platform plans
Mosey's technology will support a product called Gusto Business Compliance. Gusto plans to build compliance management into its broader payroll, HR and benefits offering, using automation and AI to handle parts of the process behind the scenes.
The acquisition also reflects a broader trend among software groups serving small businesses, as providers expand beyond core payroll or accounting functions to capture more of the administrative work tied to employment and growth.
For smaller employers, compliance has become a material operating cost rather than a background task. Gusto said 51% of small businesses report that compliance affects their growth, suggesting regulation is shaping hiring decisions and expansion plans as much as wage costs or access to finance.
Multi-state employment has added to that pressure. Remote work has made it easier for businesses to recruit outside their home state, but it has also exposed owners to new state tax, labour and registration rules that many traditional payroll systems do not fully address.
Founded in 2012 as ZenPayroll, Gusto processes payroll worth tens of billions of dollars each year and also offers employee benefits, including health insurance and retirement accounts. The company has positioned itself as a provider of integrated back-office tools for smaller employers.
