Trio built its EOR service around fintech engineering teams specifically. The same fintech-native judgment that shapes our staff augmentation work shapes this too.

Trio engineers are highly skilled at their jobs, and fully vetted by the Trio team BEFORE their resumes got to my desk. Being able to see a video of a Trio engineer walking me, in English, through the sample project he developed for Trio was a real game-changer.
When I started my new job last year, I specifically requested Trio and we have built up two teams of Trio developers. They are intelligent, ethical, hard-working, efficient, produce quality work and so kind and fun to work with. I can’t say enough good things about them… You can’t go wrong with Trio!
Trio was incredibly effective in determining our project’s needs and solving them with the right team. The engineering team had the exact expertise we needed, and provided proactive communication during development. The overall experience was clear and reliable.
Share the role, the country, and the person if you’ve already identified them.
We confirm entity requirements, compliance obligations, and a realistic timeline for that specific country.
Your engineer is legally employed through Trio’s EOR entity, typically within days.
Tickets, standups, review, performance, all exactly as it would be with an internal hire.
Payroll, statutory filings, and benefits administration continue in the background without your involvement.

An Employer of Record is a specific, well-defined tool. It does not work for every situation, especially not in regulated industries like fintech, but it works very well for a small subset of requirements.
Understanding exactly what it does, and just as importantly what it doesn’t, is essential to deciding if this might be the right option for your company and the software you are trying to get on the market.
To find out more about whether or not our EOR services are the right fit for you, book a call.

Contractor arrangements are where we see most LATAM compliance failures happening.
The biggest issue here is that the line between a genuine contractor and a de facto employee is thinner than most US companies expect. In regions like Brazil and Mexico, authorities have started enforcing proactively, instead of reactively, using digital tracking and cross-agency data sharing to catch it.
Misclassification exposure can cost you as much as $50,000-500,000+ per worker, with retroactive liability, back benefits, social security, profit-sharing obligations, and interest.
EOR removes that misclassification risk by definition, since the worker is properly an employee from day one.
The headline fee is the smallest part of the real number, and usually sits at around $400 per employee per month, with a typical range of $199-699 depending on provider tier.
The loaded cost, built up properly:
| Layer | What It Adds |
| Gross salary | Baseline |
| Employer social contributions | Varies enormously by country, from low single digits to well over 30% |
| Statutory bonus, where mandated | Common across most of LATAM, commonly 8%+ of annual salary |
| EOR platform fee | $199-699+ per employee per month |
| Benefits markup, FX fees, per-event charges | Most providers carry several line items below the headline fee |
There are two pricing traps we see clients fall into all the time here.
Percentage-of-payroll pricing punishes senior roles directly, since engineers are expensive and a percentage model scales right along with that. At 12% on a $150,000 hire, that’s several times the flat-fee equivalent.
This just means that, for most engineering teams, flat per-employee-per-month is almost always the right structure.
Country surcharges are the second trap. A lower headline rate that surcharges a specific country can end up costing more than a slightly higher rate that doesn’t. You should always compare against your actual country mix rather than a generic list price.
Also don’t forget the costs that are never billed directly, like recruitment time, the vacancy when someone resigns, and the cost of doing the whole search again.
Under an EOR, all of that is yours. Under staff augmentation, it’s already built into what you’re quoted.
While an EOR genuinely removes entity risk, misclassification risk, and the burden of local payroll and filing compliance, it does not remove every risk. Three survive it, each with a real price tag attached if ignored.
Tax authorities assess substance, so permanent establishment risk depends on what your people actually do, and using an EOR does not by itself resolve it.
The behavior that raises PE questions is directing work closely and integrating someone into your operations.
That’s usually exactly how a software engineer gets managed. They take tickets from your backlog, attend your standup, work in your repository, and get reviewed by your tech lead.
An EOR arrangement where you retain full day-to-day direction is, in substance, exactly the thing PE analysis looks for.
It’s worth talking to counsel to figure out how to avoid this risk.
Converting a long-running contractor to EOR employment doesn’t erase the period before the conversion.
Retrospective liability from the contractor phase isn’t automatically absorbed unless the agreement says so explicitly.
If an EOR relationship ends, there’s going to be a real transition window to stand up an alternative for people who are legally that provider’s employees.
The transition clause, the liability cap, and the indemnification terms are the three things that actually determine what happens if this becomes relevant.
EOR fits clearly when you’ve already found the person, a specific engineer, referred or headhunted, who lives somewhere you have no entity, and you just need a way to legally employ them.
It’s also the strongest fit when converting a contractor who’s become a de facto employee, which is becoming an increasingly urgent move thanks to the enforcement trends in markets like Mexico and Brazil specifically.
Staff augmentation fits when you need capability rather than a specific person.
For example, you may know that you need a senior payments engineer, but you may not have a candidate or want to run the search yourself.
It also fits when speed matters more than permanence. Sourcing a senior LATAM engineer independently takes weeks to months, while a benched provider can place someone in days.
Once you strip away the pricing factor, you need to consider if you have a person, or if you have a need?
A person means EOR, or an entity at scale. A need, with recruiting capability and time, still means EOR works, but you will have to run the search yourself.
A need, without recruiting capability or time, means staff augmentation will be a far better fit for your company.
A genuinely project-shaped piece of work with real contractor independence means contractor, carefully, with counsel.
If you need 25 or more people in one country, it’s probably time to start thinking about a local entity.
From what we have observed, a hybrid approach is the most common and often the most sensible option.
To do this, we recommend staff augmentation where you need to move now, converting the engineers who prove essential onto EOR or entity employment later.
Whichever structure fits, Trio can help you get there. Request a consult.
Frequently Asked Questions
When you should set up your own entity depends on the country. 8-12 employees is a good time to start considering it, but that number might realistically be closer to 15-25 in many markets, higher where compliance overhead is heavier.
You should use an EOR instead of staff augmentation if you’ve already found a specific person, you’re converting a long-running contractor, or you want them on your team permanently.
No, an EOR does not eliminate permanent establishment risk. Tax authorities assess substance, not paperwork, so PE risk depends on how closely you direct your people, which is exactly how software work gets managed.
An EOR employs a person you already found. Staff augmentation finds, vets, employs, and replaces the person for you. It comes down to whether you have a person or a need.
The cost of an EOR is around $400/month per person, ranging from $199 to 699. On top of that, you may need to pay employer contributions, which could run from the low single digits to over 30% depending on the country.
An Employer of Record becomes the legal employer in the worker’s country, handling payroll, tax, social security, and statutory benefits. It doesn’t source, assess, manage, or replace anyone.
