There are several operating models available to US-based B2B tech companies entering Mexico: a DIY stand-alone entity, the Build-Operate-Transfer (BOT) model, an Employer of Record, and the Subsidiary-as-a-Service model. Each one produces a fundamentally different cost structure, risk profile, implementation timeline, and long-term foundation.
This page breaks down each model across the dimensions that matter most to operators and investors, and every dimension is a consequence of that one structural choice.

THE FOUR MODELS · OVERVIEW
Expansion Models: An Overview
In the IT industry, these options can be divided into four categories based on the company’s goals and scale:
- For startups hiring one individual they know from anywhere in the world, an Employer of Record (EOR) is the common option.
- For small teams or temporary project deployments with a hybrid work arrangement, companies move from EOR to the SUBaaS model to provide end-to-end support — recruiting, compliance, payroll, and local presence — without permanent commitment.
- For building a permanent nearshore center, from 20 to 150 people, the Subsidiary-as-a-Service (SUBaaS) model offers a scalable, cost-efficient path.
- For operations starting at 200 or more people, the standalone DIY entity is the primary option, but it can be assisted with the BOT model or the scalable SUBaaS, as both have the transfer option once they are stable.
Each model has trade-offs in cost, control, risk management, and timeline.
THE FOUR MODELS
Mexico's Expansion Models
Four models exist for building foreign operations. Each involves a different trade-off between control, cost, speed, and risk. Understanding where each model fits best is the starting point for any expansion decision.
| Dimension | SUBaaS | Captive (DIY) | BOT | EOR |
|---|---|---|---|---|
| Best for | Speed, pilots, flexibility. Budget-conscious companies, any size — from small pilots to full regional centers. | Large operations from the start, budget variability not a concern, leadership experienced in local markets. | Large operations where budget variability is a concern and leadership lacks local bandwidth. | Single remote hires across multiple countries. Not suited for building a team. |
| Ownership | Company owns and operates the team; uses a partner's legal and operational infrastructure. | Company fully owns and operates everything. All resources internally managed. | Operating vendor owns the entity during the build phase before transferring to the client. | Employer of Record is the legal employer. Company directs the work. |
| Control | High. Local team managed by the company, uses its systems and follows its guidelines. Partner handles administration. | High. Full control over operations, processes, and decisions. | Lower initial control. External partner leads all operations during the build phase (typically 2–5 years). | Medium. Company directs work; EOR manages employment compliance. |
| Setup time | Weeks, not months. Fastest of all models. | 6–8 months before first productive hire. | Similar to DIY — new entity setup from the ground up. | Days for first hire. Not a team-building model. |
| Cost | Highest cost-efficiency — lower setup costs and lower day-to-day operating costs than a Captive. | Costly setup. International legal and compliance advisory drives up costs rapidly in Year 1. | Higher than Captive due to partner margin. Creates pressure to transfer the operation on a compressed timeline. | Lower than DIY & BOT. Higher than SUBaaS, as client hires separate vendors for recruiting, facilities, operations compliance, etc. |
| Flexibility | High. Can start any size, validate, scale, and exit. Shutdown cost exposure reduced by 80%+ vs. a standalone entity. | Medium once operational. Low shutdown feasibility. Fixed infrastructure creates exit costs. | Limited. Long-term commitment expected. Expensive exit. | High per individual. Not designed for team-level flexibility. |
| Risk | Lower — partner absorbs many local risks. Compliance handled by a multi-company specialist team. | Higher — full accountability for compliance, performance, and market risk. Steeper learning curve. | Lower local risk — partner absorbs compliance risk. Same compliance advantage as SUBaaS, with less control. | Low for 1–3 persons. Compliance gaps emerge quickly at team scale and multiple vendors. |
| Local Presence | Yes | Yes | Yes | No |

SMALL TEAMS & TEMPORARY HIRING
Hiring a small team
For companies hiring individual contributors or a small team — whether for a temporary project or a permanent operation — there are a few options. We are discarding staff leasing from another firm, as those workers cannot be hired directly by your company when the contract ends. An EOR is the go-to payment tool for a startup that needs one expert engineer, fast, from anywhere. But it doesn’t work well for hiring a team, whether temporary or permanent, because recruiting, local presence, compliance monitoring, procurement, and day-to-day operational coordination are handled by separate providers that you must manage in a foreign country.
Too strategic for an EOR. Too small for a standalone operation (DIY) or the BOT model. That’s exactly where the Subsidiary-as-a-Service (SUBaaS) scalable model fits.
NEARSHORE OFFICE & CENTER OF EXCELLENCE
Building a full Mexico operation
When the goal is a permanent nearshore office or a full Center of Excellence, the model decision determines cost structure, timeline, and risk exposure for years. Three models are the most used and each has its own variables.
DIY — Stand-Alone Entity
The company incorporates a Mexican legal entity, opens a local bank account, hires administrative staff, and manages all legal, HR, payroll, tax, and compliance obligations independently under Mexican law.
Needs certain size to reach cost-efficient threshold to offset setup and ongoing support costs.
Best suited for
Large operations from the start. Budget variability is not a concern. Leadership team experienced in local markets. No urgency in time to value.
BOT — Build-Operate-Transfer
A local partner builds and operates the new entity with an expected size from the ground up, stabilizes it, then transfers ownership after an agreed period.
The contract requires long-term headcount and infrastructure commitments.
Best suited for
Large operations where budget variability is a concern and leadership lacks local bandwidth. No urgency in time to value.
Note: Cost is higher than DIY — the partner charges a margin on the total operation.
SUBaaS — Subsidiary-as-a-Service
The client operates under the partner’s existing legal, HR, payroll, and facilities infrastructure with full operational ownership and brand control from day one. Pay-per-use, no entity build required. Can transfer to a standalone entity when the scale is right.
Best suited for
Any size — from small pilot teams to full Centers of Excellence. Budget-conscious companies. Time to value is a concern.

DECIDING BASED ON OPERATIONAL SCALE
Which Model Fits Your Operational Scale
Company size influences the decision, but the level of commitment and the intended scale of the new operation in Mexico have the greatest impact on the expansion strategy.
| Operational Scale | Options | Why |
|---|---|---|
| 1 to 3 hires, speed priority, no intent to scale | EOR, SUBaaS | Lowest friction for small headcount, no infrastructure investment needed, temporary or permanent hiring. |
| 5 to 100 headcount, no long-term fixed hiring | SUBaaS | Cost-efficient since day one, operational in 30 to 45 days, full brand ownership, scale only when needed, lower exit risk. |
| 100+ employees on first year | DIY or SUBaaS hybrid | Leverage SUBaaS in the first years to avoid high setup costs and learning curve, stabilize operation, then transfer to stand alone. |
| 300+ employees | SUBaaS hybrid, BOT, DIY | Leverage SUBaaS or BOT for budget control on the first years, stabilize operation, then transfer to stand alone. |
A well-designed team running under the wrong model will systematically underperform its savings potential. The talent strategy and the operational structure must both be resolved before any cost projection is valid.

COMMON QUESTIONS
Frequently asked questions about Mexico expansion models.
Q01What is a soft landing in Mexico for a tech company?
A soft landing is a structured market entry that avoids the overhead and local risk of an immediate full-scale entity build. Instead of incorporating a standalone Mexico company from day one, a tech company launches operations on top of an existing local operating infrastructure, reducing setup time, lowering initial cost, and limiting legal exposure during the validation phase. SUBaaS is the IT industry implementation of this approach.
Q02How long does it take to set up a Mexico entity?
A DIY stand-alone operation in Mexico takes 4 to 8 months from decision to first productive hire, including entity incorporation, SAT and IMSS registration, bank account setup, accounting software and processes, and first administrative hires. The timeline can be longer, as it is dependent on different government instances availability.
Q03What is Subsidiary-as-a-Service (SUBaaS)?
Subsidiary-as-a-Service (SUBaaS) is a Mexico operations model that lets a company launch and run its own Mexico team on top of an existing operating infrastructure — without setting up a standalone legal entity. The company retains full ownership and brand control from day one. Everscale runs the employment, payroll, HR, facilities, and compliance infrastructure in the background. The model is pay-per-use: cost efficiency begins from the first hire, scales to any size, and includes the option to transition to a standalone entity at any point. The model is also known as GCC-as-a-Service, Virtual Subsidiary, and Micro Capability Center.
Q04What is the difference between SUBaaS and EOR?
EOR provides payroll processing, only. It does not include facilities, HR management, an onboarding infrastructure, benefits design, management support, compliance monitoring, and more. Soon, the company is hiring multiple vendors, creating accountability gaps and building the wrong foundation. For a single remote hire, EOR can be adequate, but for a team that needs to function as a cohesive business unit with local presence, SUBaaS is the full accountable operating platform.
Q05What happens if we need to shut down a Mexico operation?
Under a DIY entity, shutdown cost exposure for a 30-person team reaches $512K at Year 1 and $1.16M at Year 2, including sunk costs, mandatory severance under Mexican Federal Labor Law, entity dissolution fees, and lease cancellations. Under the as-a-Service model, that exposure drops by 83% at Year 1 because the administrative infrastructure is reassigned rather than dissolved.
Q06Can a PE Portfolio company run Mexico operations without setting up its own legal entity?
Yes, that is one of the primary use cases for SUBaaS. Portfolio companies that operate under the as-a-Service framework reduce setup cost, timeline, and shutdown cost exposure. The portco retains full management authority and team ownership from day one. It can transfer the operation when the scale reaches efficiency.
