What is human resource outsourcing?
Human resource outsourcing (HRO) is when a company hands some or all of its HR functions to an external provider, for example payroll, HR administration, recruitment or benefits. The company stays the employer and keeps responsibility for its people, while the provider runs the agreed processes under a service contract.
| Function | What the provider does |
|---|---|
| Payroll | Calculates pay, deductions and taxes, prepares payslips and filings |
| HR administration | Keeps employee records, contracts and HR documents up to date |
| Recruitment | Sources and screens candidates, sometimes runs the whole hiring process (RPO) |
| Benefits administration | Manages pensions, insurance and other benefits |
| Training | Designs and delivers training programs |
| HR advice and compliance | Advises on employment law, policies and disputes |
HR outsourcing is one type of outsourcing: the provider takes over HR processes, not the company's core work. In outstaffing or with an employer of record, the provider becomes the legal employer of people who work for you. With HRO, your employees stay yours.
| Pros | Cons |
|---|---|
| Lower cost than a full in-house team for small companies | Less control over processes and service quality |
| Access to legal and payroll expertise | Sensitive employee data is shared with a third party |
| Easy to scale up or down | Slower answers for employees if the provider is not close to the team |
| HR team can focus on strategic work | Switching providers takes time and effort |
Under UK GDPR the provider acts as a data processor, so Article 28 requires a written contract that sets out how it may use employee data. If staff move to the provider as part of the deal, TUPE rules can apply and their employment terms transfer with them.
Many companies combine an in-house team with an external provider. In Core HR, employee data stays in one place, and access roles let you open only the sections an external partner needs. Routine work that often gets outsourced, such as leave tracking and document approvals, can be automated inside the company instead.
A 60-person company hands payroll and HR paperwork to an accounting firm, while its own HR manager keeps hiring, onboarding and employee engagement.
Often yes for payroll and legal compliance, where mistakes are costly and a full-time specialist is hard to justify. Work that shapes culture, such as hiring and engagement, usually works better in-house.
