Frequently Asked Questions (FAQs)

Learn more about the benefits of payroll solutions for businesses, accounting firms or a payroll service bureaus.

Payroll is how businesses pay their employees. It includes calculating wages, withholding taxes, deducting benefits, and making sure payments go out on time. It also covers keeping records and staying compliant with labor laws and tax regulations.
Processing payroll, or running payroll, involves a few key steps: gathering employee details (like hours worked, salaries, and tax details), calculating gross pay, deducting taxes and benefits, paying employees (via direct deposit or checks), and filing tax forms.

Some businesses handle payroll in-house using payroll software or a payroll team, for full control. Others outsource it to a payroll service provider, which takes care of everything—compliance, tax filings, and payments, —so they don’t have to worry about admin work, errors, or penalties.

Payroll compliance laws make sure businesses pay employees fairly and follow tax rules. In the U.S. that includes laws like the Fair Labor Standards Act (FLSA), which covers minimum wage, overtime pay, and record keeping, and Federal Insurance Contributions Act (FICA), which requires employers to withhold Social Security and Medicare taxes). There are also state-specific payroll compliance laws to follow.  
A payroll provider is a company that handles payroll for businesses. They manage wage calculations, tax filings, compliance, and employee payments, usually with payroll software to make things easier.
It depends on what you need. Think about pricing, features (e.g., tax filing, direct deposit, benefits management), ease of use, and integration with your existing tools., Good customer support, and compliance expertise are key, too.
