Employer of Record: Cutting the Fixed Costs of Hiring Abroad

An employer of record (EOR) is a third-party organisation that becomes the legal employer of a worker in another country, running payroll, tax and statutory contributions, while the client business directs the worker's day-to-day job. For firms hiring abroad, the attraction is largely economic. It lowers the cost of entering a foreign labour market and transfers the burden of unfamiliar payroll rules to a specialist. Understanding why this works, and where it stops working, requires looking at fixed costs, economies of scale, exchange rates and information.

Fixed Costs as a Barrier to Hiring Abroad

To employ someone directly in another country, a business usually needs to register as an employer there and often to set up a local subsidiary. That involves legal fees, registrations, local bank accounts and a payroll system built around the country's tax and social contribution rules. These are fixed costs: they must be paid whether the firm hires one person or more.

For a company with few planned hires, fixed costs are spread across fewer workers, making the average cost per employee relatively high. Most of these fixed and sunk costs cannot be recovered if the business does not succeed. These high fixed and sunk costs create a barrier to entry that makes it less attractive for smaller companies to hire workers overseas, even if they have found the ideal candidate.

Economies of Scale in Payroll Compliance

Payroll knowledge is expensive to build but cheap to reuse. Once a provider has learned a country's tax bands, deduction rules and filing deadlines, applying that knowledge to one more employee costs little. This is a classic source of economies of scale, where average costs fall as output rises.

An EOR makes use of this by serving many client firms in the same country through a single legal entity and payroll system. The fixed cost of compliance is spread across a large number of employees, so each client pays a fraction of what building its own operation would cost. For the client, a large fixed cost is replaced by a monthly fee per employee, which behaves like a variable cost and rises only as the team grows.

Exchange Rate Risk in International Pay

Employees abroad are usually paid in local currency, while the employer reports its costs in its home currency. When exchange rates move, the home-currency cost of the same salary changes. If sterling weakens against the currency in which a worker is paid, a UK firm's wage bill rises even though the worker's pay is unchanged.

Using an intermediary does not remove this risk, which stays with the business paying the wages. It does, however, simplify the mechanics of converting and paying salaries across several currencies, and consolidated records make the effect of currency movements on total labour costs easier to track. Firms with large overseas payrolls may still choose to manage the risk directly, for example through forward contracts that fix a future exchange rate.

Information Asymmetry and Compliance Risk

When a company starts conducting business internationally, it often has far less knowledge of the country's tax and labour law systems than local experts. This information gap creates several risks. Miscalculating deductions or making statutory payments late can result in fines, back payments and disputes. Acquiring this information independently can be costly, and companies may make mistakes while learning the country's regulatory requirements.

Payroll errors also carry a less visible cost. Late or incorrect pay damages trust, and dissatisfied employees are more likely to leave. Labour turnover is expensive, because each departure brings fresh recruitment and training costs. Accurate, punctual payroll therefore protects the firm's investment in its workforce, not only its legal position.

Wider Access to International Labour Markets

Reducing barriers to entry allows a business to access a greater number of workers, increasing their ability to find qualified candidates. Companies with skill shortages may be able to hire foreign workers without opening offices in other countries, giving them access to a wider pool of qualified candidates. Companies may also pay lower wages in some countries because of differences in wage structures. However, firms competing for scarce talent may need to offer similar rates internationally, regardless of where their workers are located.

The Make-or-Buy Decision and Its Limits

Using a local entity or an employer of record is one option in the make-or-buy decision surrounding foreign employment. For a small number of hires, using an employer of record may be less expensive. However, as the number of employees increases, the overall cost of using an employer of record could eventually exceed the cost of establishing an international subsidiary. In addition, when using an intermediary employer of record, the client loses some control over those employees and enters into a principal-agent relationship with that entity; therefore, ongoing monitoring will be required.

Weighing the Costs and Benefits of an Employer of Record

An employer of record uses economies of scale to convert high fixed costs into manageable variable costs while simplifying multi-currency payroll and reducing compliance risks. For companies with a small number of international hires, having an EOR is typically a less expensive option than establishing a local subsidiary. However, as businesses build larger teams in one country or region, it may become more cost-effective to have a local entity maintain compliance with local labour laws and pay their employees directly.
