One Source Employer Services

One Source Employer Services gives U. S. Businesses a single point of contact for payroll, human resources, employee benefits, and employer risk management. Based in Tempe, Arizona and operating since 2001, OneSource has spent more than 25 years helping employers across the country offload the administrative complexity that comes with running a workforce, so leadership can stay focused on the work that moves the business forward. The services OneSource offers cover every major area of employee administration. Payroll processing handles accurate, timely pay runs along with direct deposit, tax deposits, certified payroll, job costing, and customized reporting. HR support extends from initial onboarding and employee recordkeeping through policy development, performance management, compliance, and employee relations. For employers who want to consolidate these functions into a formal outsourcing arrangement, OneSource offers both PEO and ASO structures, giving clients the flexibility to choose how much administrative responsibility they transfer and how much they retain. Employee benefits administration and workers' compensation round out the back-office picture. OneSource coordinates enrollment, eligibility, employee communications, and payroll deductions for benefits, and manages workers' compensation coverage, claims coordination, safety programs, OSHA assistance, and return-to-work planning. Bringing these functions together with a single partner reduces the vendor fragmentation that often makes workforce costs harder to track and control. What sets OneSource apart from the large national HR outsourcing platforms is straightforward: it is a locally owned, locally operated firm where clients reach experienced professionals, not automated portals. BBB Accredited with an A+ rating, the company operates from its Tempe headquarters while serving employers nationwide. When a payroll issue needs to be resolved the same day or an HR situation cannot wait for a callback, clients have a direct line to people who know their account. For companies that want a clearer picture of where their HR practices stand, OneSource offers a complimentary Human Resources Assessment, a written review with no obligation. To discuss payroll, HR, benefits, or risk management for your organization, call (602) 553-8300 or request a consultation on the OneSource website.
