Payroll Companies & Payroll Services in Manchester, NH

Trivantus is a payroll and human capital management provider headquartered in Manchester, New Hampshire. Since 2003 it has given employers an alternative to handling payroll, taxes and HR paperwork themselves. It works with companies ranging from a single worker to organizations with more than a thousand staff.

Its main focus is northern New England, with dedicated resources for Maine, Massachusetts and New Hampshire, but it also has clients in other parts of the country. It also runs a program aimed at seasonal operations.

Payroll and Tax Services

The core offering is Freedom Payroll, a cloud-based system that sits inside the company's broader Freedom HCM suite. Because payroll, HR, benefits and timekeeping share one employee record, changes flow through the platform as they happen rather than waiting on separate modules to sync.

A configurable pay rules engine handles overtime, shift differentials, and workers who hold more than one role or work at several sites. On the tax side, Trivantus computes liabilities, makes deposits and submits returns to federal, state and local agencies on a client's behalf. It also handles any agency notices that follow, along with W-2 and 1099 preparation.

• Direct deposit to any number of checking, savings or money market accounts, plus paper checks
• Payroll reports that can be exported or emailed automatically after each run
• General ledger exports for import into accounting software
• 401(k) support covering deferrals, employer matches, safe harbor contributions, loans and census reporting
• Automated federal and state new hire reporting
• Garnishment, levy and child support remittance

HR, Benefits and Compliance Tools

Beyond paychecks, the platform includes time and attendance tracking, employee scheduling, recruiting, onboarding, online benefits enrollment, ACA reporting, performance management, a compliance hub and a mobile app. Optional add-ons carry the Freedom brand. These include background screening through a partnership with National Crime Search, labor law posters with ongoing updates, and E-Verify eligibility checks.

Clients can also get Social Security number validation through the SSA to help keep year-end W-2s accurate. Freedom Flex sets up and maintains a Section 125 premium-only plan, with yearly testing, so staff can pay benefit premiums with pre-tax dollars.

Workers' Compensation

Through Freedom Comp, Trivantus arranges pay-as-you-go workers' compensation coverage with brokers nationwide and access to more than 50 carriers. Premiums are calculated from actual wages each pay period instead of an upfront estimate. No deposit is required, although some states may still charge mandatory assessments. Trivantus sends the wage and premium figures to carriers itself, which the company says simplifies audits and reduces surprises at year end.

Background and Approach

The business is owned by the Gatsas family. Michael Gatsas previously helped launch Staffing Network, a professional employer organization that became a major New England employer. Trivantus cites more than 252 years of combined staff experience and over ten million checks processed. Its stated philosophy centers on building relationships through clear communication and personal attention.

Client testimonials highlight smooth transitions and responsive help, even for small accounts. The firm also runs a referral initiative, Checks for Charities, which pairs fee credits with donations to charities chosen by clients.
