EOR or Representative Office in Vietnam is a question many foreign businesses face when entering the market: should they recruit through an EOR or open a representative office from the outset? Is it really necessary to establish a legal entity just because someone is working in the market? Or are there more flexible options that help avoid legal constraints from the start?
In this article, Green NRJ examines this issue from both a legal and operational perspective to determine when to use an EOR, when to open a representative office, and why many businesses do not choose one path from the very beginning.

ToggleWhen businesses consider entering Vietnam, the story often starts simply: they need local staff. But going from “having people” to “having a legal presence” are two completely different steps.
According to Vietnamese law, a representative office is not a business entity and is only permitted to conduct communication, market research, and trade promotion activities. If a representative office engages in revenue-generating activities, the risk of being considered an illegal business operation is entirely possible. This might seem sufficient for the initial stage, but in reality, many businesses only realize this limitation when their operations have begun to expand.
Conversely, EOR services in Vietnam take a different approach. Businesses don’t need to establish a legal entity, but can still legally recruit personnel through a third-party labor agency. This might sound “strange” to many people hearing it for the first time, but in fact, this is a model that has been quite commonly used in international human resource management.
The difference lies in the fact that one is about “presence,” while the other is about “immediate operation.” For a broader comparison with other flexible hiring models, you can also refer to our analysis on EOR vs outsourcing in Vietnam.
Many businesses face a reality: they are uncertain about the market, but still need to act. This could be to find customers, build relationships, or simply verify demand.
If they choose to open a representative office from the start, they will have to go through a process that isn’t overly complicated, but is time-consuming enough. More importantly, even after having an office, they are still limited in their operations—unable to directly sign contracts and generate revenue.
Meanwhile, EOR solves this very “bottleneck.” Businesses can hire almost immediately. Personnel can work, develop the market, and even support sales. All of this is legal, because legally, employees are contracted with the EOR and fully comply with tax and insurance obligations as stipulated in Vietnam.
Of course, this flexibility comes with a service fee. But when weighed against the opportunity costs — delays, missed market opportunities — many businesses still find this a reasonable option.
But EOR (Employee Ownership Authority) isn’t always the answer. There are times when businesses need a more visible presence, especially when working with large partners or building trust in the market. In this case, a representative office acts as an “official touchpoint.” It doesn’t generate revenue, but it creates a presence. And sometimes, that alone is crucial. However, this is also where many businesses fall into misunderstandings. They think that having a representative office means they can operate their business. But according to regulations, if a representative office engages in revenue-generating activities, the legal risks are real—and not insignificant. Therefore, this option is only truly suitable when the business understands its limitations and has a clear long-term plan.
Looking closer, the question “EOR or representative office?” isn’t really about the model. It’s about timing. In the early stages, when things are still uncertain, businesses often need flexibility. They need to experiment, adjust, and sometimes withdraw quickly if the market doesn’t meet expectations. An EOR fits that. But as the market becomes clearer, and the business has a long-term vision, the needs change. At this point, stability and presence become more important. And that’s where a representative office comes in. In fact, many businesses don’t choose one over the other. They start with an EOR, then move to a representative office or even establish a company. That’s not a drastic change of mind. It’s a natural progression.
Conversely, choosing the wrong model from the outset can lead to restructuring, increased costs, and even legal risks during operation.
In the “employment through EOR or opening a representative office” scenario, Green NRJ supports businesses in evaluating the most suitable model from the outset – from legal aspects and operational structure to practical implementation in Vietnam. This helps businesses avoid mistakes at the very beginning, instead of having to deal with the consequences later. In reality, each business has a different starting point. We usually begin by asking ourselves: what are the market entry goals? How fast do we need to go? What level of risk are we willing to accept? It sounds simple, but these questions determine almost all subsequent choices. From there, Green NRJ will analyze both the legal aspects – including scope of operations, compliance obligations, and potential risks – and the practical operational aspects, such as costs, time, and scalability.
With our EOR service in Vietnam, we help businesses deploy their workforce quickly and legally, without needing to establish a legal structure from scratch. Through our representative office model, we provide support from licensing procedures to operational consulting, helping businesses avoid common risks.
Hiring personnel through EOR or opening a representative office is not a right or wrong choice. It’s a choice that suits the situation at each point in time. If a business needs speed and flexibility to test the market, EOR is a reasonable starting point. But if the goal is to build a long-term presence, a representative office becomes a necessary step. Most importantly, this decision should not be made hastily. If you are considering between the two models, Green NRJ can help you see the bigger picture—to make the right choice from the start and move faster in the Vietnamese market.
