Tandem HR

Tandem HR is an IRS-certified Professional Employer Organization (PEO) based in Indianapolis that takes HR administration off the plates of growing businesses, handling everything from payroll to benefits management so owners and operators can focus on what they do best. As a full-service HR outsourcing partner, Tandem HR delivers the infrastructure and expertise of a large corporate HR department without requiring clients to build one in-house. The company covers the full HR lifecycle. Payroll administration includes processing, reporting, and tax compliance, making pay cycles accurate and predictable. On benefits, Tandem HR uses bundled buying power to secure rates that individual businesses typically cannot access on their own, which translates to competitive health plans that help companies attract and keep qualified people. Human resources support covers onboarding, training, performance management, and employee relations, with dedicated professionals available for both routine questions and complex situations. Risk management services address liability exposure, safety audits, and compliance with changing state and federal employment regulations. Clients also access PeopleHub, the company's proprietary technology portal that gives managers and employees 24/7 self-service access to HR documents, handbooks, and benefits details. Tandem HR primarily serves small to mid-sized businesses, and client testimonials tell a consistent story: companies navigating acquisitions, fast headcount growth, and open enrollment complexity that requires more than a single in-house generalist can handle. The co-employment model gives these businesses back-office HR capabilities that normally belong to much larger organizations, which matters when competing for talent in tight markets. The dedicated team model is a meaningful operational distinction. Rather than routing clients through a general support queue, each account works with assigned HR professionals who get to know the business over time. Clients describe their Tandem contacts as a genuine extension of their own staff. The IRS CPEO certification, which requires meeting strict financial and reporting standards, provides added confidence for businesses that need a dependable outsourcing partner for compliance and payroll. For companies considering HR outsourcing as a way to reduce administrative burden and give employees a better experience, Tandem HR offers a direct path to both.
