What a third-party administrator does and when to use one

Executive overview

Small and mid-sized businesses often lack the in-house capacity to manage the complexity of employee benefits, claims, COBRA, and compliance. A third-party administrator (TPA) takes over these tasks, bringing specialised knowledge and established processes.

The case for a TPA comes down to three things: lower cost than hiring in-house, specialist expertise to reduce errors, and staying compliant with constantly changing benefit regulations.

Outsourcing benefits administration to a TPA lets HR teams focus on higher-value work while reducing compliance risk.

Why small and mid-sized businesses use TPAs

• Cheaper than hiring additional internal HR staff for specialised tasks
• Reduces errors in benefits management through specialist knowledge
• Keeps the organisation compliant as regulations change — without requiring internal tracking

Common TPA services

• Managing employee health benefits and processing claims
• COBRA and state continuation administration
• Retirement plan management
• FSAs, dependent care FSAs, HRAs, HSAs, and commuter benefits

What to look for when selecting a TPA

• Expertise: proven track record in the specific services you need
• Customer service: responsive and easy to work with — they become an extension of your HR team
• Technology: modern platforms that integrate with your existing HR tools
• Pricing: transparent fee structure, no hidden costs, flexible contract terms
