Human resource outsourcing (HRO)

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.

HR outsourcing, outsourcing and outstaffing

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.

How to outsource HR functions

  1. Choose what to outsource. Start with repetitive, rules-based work such as payroll or HR administration.
  2. Compare providers on expertise, references, data security and price.
  3. Agree an SLA with scope, deadlines, quality metrics and who answers employees' questions.
  4. Sign a data processing agreement and limit the provider's access to the data it needs.
  5. Review the results regularly against the SLA.

HR outsourcing in the UK

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.

HR outsourcing and PeopleForce

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.

FAQ

What is an example of HR outsourcing?

A 60-person company hands payroll and HR paperwork to an accounting firm, while its own HR manager keeps hiring, onboarding and employee engagement.

Is HR outsourcing worth it for small businesses?

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.
