HR and Workforce Services: Options, Costs & Top Providers

HR and workforce services help businesses manage employees from hire to retire. HR services cover recruiting, onboarding, benefits, compliance, handbooks, performance and employee relations, while workforce services cover time and attendance, scheduling, leave and labor cost management. Both connect to payroll, and businesses can get them through HR software, an ASO, a PEO, consultants or an in-house team.

HR software typically costs about $6 to $15 per employee per month, HR consulting about $100 to $200 per hour, an administrative services organization about $50 to $250 per employee per month, and a PEO about $100 to $250 per employee per month or 2% to 12% of payroll. Insurance premiums are usually extra.

A PEO becomes a co-employer, running payroll under its own tax ID and offering access to large-group benefits and workers’ compensation. An ASO provides similar HR and payroll administration without co-employment, so your business stays the sole employer and keeps its own benefit plans.

HR services focus on the employee relationship, such as hiring, benefits, compliance, policies and performance. Workforce management focuses on deploying labor efficiently, such as scheduling, time and attendance, leave tracking and labor forecasting. Many platforms combine both with payroll.

Consider outsourcing HR when you reach about 10 to 15 employees, hire in a new state, face a compliance issue or employee complaint, want better benefits, or when the owner or office manager spends hours a week on HR tasks.

For most businesses under about 100 employees, outsourcing is cheaper. HR managers earn a median of about $140,030 a year before benefits, while outsourcing HR for 50 employees typically costs about $2,500 to $12,500 per month depending on the model and services.

Federal anti-discrimination laws including Title VII and the ADA apply at 15 employees, age discrimination rules and COBRA at 20, FMLA and the ACA employer mandate at 50, and EEO-1 reporting and the WARN Act at 100. Many states apply similar rules at lower headcounts.

Yes. Most major payroll companies, including ADP, Paychex, Paycor, Paylocity, Rippling and Gusto, offer HR tools or HR services alongside payroll, and ADP and Paychex also offer PEOs.

A PEO typically provides payroll and tax filing, benefits administration with access to large-group health plans, workers’ compensation, HR compliance support, employee handbooks, training and help with hiring, discipline and terminations.

Yes. Many businesses keep HR software in-house and outsource specific functions such as payroll, benefits administration, recruiting, compliance audits or handbook creation, either through an ASO, an HR consultant or add-on services from their payroll provider.

Look for experience with businesses your size and industry, coverage in all your states, integration with payroll and time tracking, access to certified HR professionals, clear pricing, strong data security and contract terms that let you leave without heavy fees.

No. Even with a PEO or ASO, your business remains responsible for managing employees and following employment laws. Providers share or take on specific responsibilities, such as payroll tax filing for a certified PEO, but they don’t eliminate your obligations.
