Use an Employer of Record (EOR) in Mexico when you have only 1–2 hires, your time horizon is under 12 months, you’re testing the market, or your team has no bandwidth to oversee a Mexican subsidiary. Open your own Mexican entity (an S de RL de CV or SA de CV) when you plan to hire 3 or more employees on a multi-year horizon, need to invoice in Mexico, hold IP-sensitive work, or run manufacturing under IMMEX. EOR gets you live in 5 business days; incorporation takes 8–12 weeks but starts paying off as soon as you cross 3 employees on a 36-month horizon.
That’s the short answer. The rest of this guide is for the CFO, COO, or Head of People who has to defend the choice to a board.

The 60-second decision table
| Factor | EOR (Employer of Record) | Your own Mexican entity (S de RL or SA de CV) |
|---|---|---|
| Ideal use case | Test market, sales coverage, first 1–2 hires, short-term project, or no bandwidth for entity oversight | Long-term operations, hiring at scale, IP-sensitive work, manufacturing, local invoicing |
| Headcount range | 1–2 employees ideal; viable up to ~10 | 3+ employees, no upper limit |
| Time to first hire | 5 business days | 8–12 weeks (incorporation + IMSS/INFONAVIT employer registration) |
| Setup cost | $0 (rolled into monthly fee) | USD $3,500–$4,500 one-time (notary, capital, legal, RFC, IMSS/INFONAVIT registration) |
| Ongoing cost | From $450/employee/month at the entry tier, decreasing with headcount. Capped at 15% of gross salary, whichever is less. REPSE-regulated roles may carry an additional fee. Full pricing → | Flat USD $1,000–$1,500/month for accounting, payroll, CFDI issuance, and IMSS/INFONAVIT filings — regardless of headcount |
| 3-year TCO (5 employees) | ~USD $81,000 in EOR fees | ~USD $40,000–$62,000 all-in (incorporation + 36 months of compliance overhead) |
| Operational overhead for the foreign team | Effectively zero — Start-Ops handles the labor relationship end-to-end | Some — you own a Mexican entity and have ongoing fiduciary, banking, and statutory responsibilities even when a specialist runs day-to-day |
| Tax / permanent establishment risk | Low — the EOR is the legal employer of record | Low if structured correctly; the entity itself is the taxpayer |
| IP control | IP assigned via contract; some buyers find this thin for sensitive work | Direct — your Mexican entity owns IP and contracts |
| Local invoicing (CFDI) and Mexican RFC | No — you cannot invoice Mexican customers as a Mexican supplier | Yes — required for B2G, large enterprise, and most local commercial contracts |
| Exit complexity | Cancel the contract, terminate or transition employees | Wind-down takes 6–12 months; involves SAT, IMSS, and notary |
| When to switch | Once headcount crosses ~3 and the operation is committed | If headcount drops below 3 long-term, or you exit Mexico |
The table is honest about both paths. The next eight sections explain each row in operational detail.
What is an EOR in Mexico, and what is “your own Mexican entity”?
An Employer of Record (EOR) in Mexico is a registered Mexican company that legally employs your workers on your behalf. The EOR holds the labor contract, runs payroll, files monthly with IMSS (Instituto Mexicano del Seguro Social, the social security agency) and INFONAVIT (the housing fund), issues CFDI payroll receipts (Mexico’s mandatory electronic payroll format), and handles severance if it ever comes to that. You direct the work day-to-day. You pay the EOR a monthly fee.
Your own Mexican entity means you incorporate a Mexican legal person — almost always an S de RL de CV (similar to a US LLC) or an SA de CV (similar to a US C-corp). The entity gets its own RFC (Registro Federal de Contribuyentes — Mexico’s tax ID), opens Mexican bank accounts, registers with SAT (the tax authority), registers as an employer with IMSS and INFONAVIT, and signs labor contracts directly with employees.
A note on terminology: EOR is not the same as a PEO (Professional Employer Organization). A PEO operates under a co-employment model that requires you to already have a Mexican entity. In Mexico, what most US buyers actually want when they say “PEO” is an EOR. The 2021 outsourcing reform (a major rewrite of the Federal Labor Law, or LFT, by Mexico’s labor ministry STPS) banned generic personnel-leasing arrangements and replaced them with a stricter framework: only specialized services registered in REPSE (the Registry of Specialized Service Providers) can lawfully provide outsourced personnel. EOR work in Mexico must be performed by a REPSE-registered provider — that’s the legal floor, not a marketing claim.
When is an EOR the right call?
EOR genuinely wins in five scenarios. We say this knowing we offer entity formation, EOR, and everything in between — about 4 in 5 of our clients ultimately incorporate, but the other fifth would have wasted money doing so.
1. You’re hiring fewer than 3 people in Mexico. The fixed monthly cost of running a Mexican entity (accounting, payroll filings, statutory reports, monthly IMSS/INFONAVIT) doesn’t scale down. Below ~3 employees, EOR’s per-employee fee is cheaper than the entity’s flat overhead. At 1–2 hires, EOR is dramatically cheaper — entity overhead would be most of your Mexico spend.
2. Your time horizon is under 12 months. Incorporation takes 8–12 weeks. A wind-down takes 6–12 months. If you’re running a 9-month pilot, an entity is a poor fit — you’ll spend more time forming and dissolving it than operating it.
3. You’re testing the Mexican market. PE-backed companies, Series A startups, and corporate development teams often want a 6–9 month look at whether Mexico works before committing capital. EOR gives you a real team, real payroll, real customer interactions — without the entity commitment.
4. You need a small sales or BD presence. Two reps covering Latin America. A solutions engineer based in Guadalajara. A customer success lead who happens to be Mexican. None of these justify entity overhead, especially since these roles rarely need to invoice in Mexico.
5. Your funding or budget can’t absorb the upfront setup. Incorporation costs roughly USD $3,500–$4,500 one-time, before you’ve made your first hire. EOR has no setup cost — your first cash outflow is your first month of payroll plus the EOR fee.
6. Your team has zero bandwidth for Mexico oversight. Even when entity is cheaper on paper, EOR may be worth the premium if no one on the foreign team has time to oversee a Mexican subsidiary. EOR means zero management overhead for the foreign team — no Mexican director coordination, no statutory filings to track, no banking relationship to maintain, no annual corporate book to keep current. A well-run Mexican entity is never quite “zero ops” even when a Mexico specialist handles the day-to-day. If your CFO is already at capacity, paying the EOR premium for that simplicity is a defensible call.
If you’re in any of the above — start with an EOR. You can always transition to your own entity later. Many of our clients do exactly that, and it’s a clean migration when the time comes. For deeper reading: permanent establishment risk in Mexico covers the tax-residency question that often pushes companies toward EOR in the first place.
When is opening your own Mexican entity the right call?
This is the harder section, and the more important one — because the buyers most likely to be misled by generic global-EOR marketing are the ones who should incorporate.
1. You’ll have 3+ employees in Mexico within 12 months. At three employees, the math flips. EOR fees (~USD $450/employee/month at the smallest tier, capped at 15% of gross salary) start to match the flat ~USD $1,000–$1,500/month it costs to run a small Mexican entity (accounting + payroll + CFDI issuance + IMSS/INFONAVIT filings). By 5 employees, entity is meaningfully cheaper. By 10, the EOR premium is unmissable. EOR scales linearly with headcount; entity overhead is largely fixed.
2. You’re committing to Mexico for 3+ years. Over 36 months, the gap between EOR and entity TCO becomes substantial — see the TCO comparison below. The longer you run, the worse EOR looks on a pure cost basis.
3. You hold IP-sensitive work in Mexico. Engineering teams, R&D, proprietary manufacturing processes. With EOR, IP assignment runs through a chain of contracts (employee → EOR → your US entity). With your own Mexican entity, the work is created inside a company you own. For sensitive work, the cleaner chain is worth the overhead.
4. You’re manufacturing in Mexico. Manufacturing almost always requires your own entity (or a shelter arrangement under someone else’s IMMEX umbrella). The IMMEX program — Mexico’s manufacturing duty-deferral regime, run by the Ministry of Economy — requires the importer of record to be a Mexican entity. If you’re nearshoring production from Asia, you’re incorporating. See the IMMEX program for manufacturers for the registration path.
5. You need to invoice Mexican customers. Mexican enterprise and government customers will require a Mexican supplier with a Mexican RFC issuing CFDI invoices. You cannot do this through an EOR — the EOR invoices you; you don’t get to invoice Mexico through them. If your business model in Mexico is selling to Mexican companies, you need your own entity.
6. You’re going after government or large-enterprise contracts. Mexican procurement processes — public sector and most Tier 1 enterprise — require an established Mexican legal entity, often with a minimum operating history (frequently 2 years on file with SAT). You can’t shortcut this.
7. Your activities in Mexico create permanent-establishment exposure. If you have employees signing contracts on your behalf, holding inventory, or running operations that constitute a “fixed place of business” in Mexico under the Mexico-US (or Mexico-Canada) tax treaty, your foreign parent may already have de facto Mexican tax obligations. Forming the Mexican entity formalizes that reality cleanly. EOR can mitigate the risk for some role types but not all — this is a question for your tax advisor, not a marketing page.
For the entity choice itself, see S de RL vs SA de CV (which to pick). Most foreign-owned Mexican subsidiaries pick S de RL de CV — fewer formalities, single-tier governance, and US LLC-like treatment for check-the-box elections — but if you anticipate raising local capital or going public, SA de CV is the path.
Total cost of ownership: 36-month comparison
The illustrative numbers below assume 5 Mexican employees with average loaded compensation of ~USD $40,000/year per employee (a typical mid-market Mexican professional salary including IMSS, INFONAVIT, aguinaldo, and PTU). All figures are USD and rounded for clarity. Exact numbers depend on entity type, state of incorporation, employee mix, salary band, and whether any roles fall under REPSE-regulated activities.
Path A — EOR
| Line item | Year 1 | Year 2 | Year 3 | 3-year total |
|---|---|---|---|---|
| Setup / onboarding | $0 | $0 | $0 | $0 |
| EOR fee (5 employees × $450/mo, tier 1, capped at 15% of gross salary) | $27,000 | $27,000 | $27,000 | $81,000 |
| Compliance/audit ad-hoc | $0–$2,000 | $0 | $0 | $0–$2,000 |
| Total EOR (5 employees, 36 months) | ~$81,000–$83,000 |
The EOR fee assumes a $450/employee/month base — Start-Ops’s entry-tier rate (capped at 15% of gross salary, whichever is less). Volume discounts compress this further above 5 employees; for the full tier breakdown, see our Mexico Employer of Record service. Roles classified as REPSE-regulated specialized services may carry an additional fee; most professional roles (sales, marketing, customer success, software engineering) are not affected. EOR fees scale linearly with headcount, while entity overhead is largely fixed.
Path B — Your own Mexican entity (S de RL de CV)
| Line item | Year 1 | Year 2 | Year 3 | 3-year total |
|---|---|---|---|---|
| All-in incorporation (notary, capital, legal, RFC, SAT, IMSS/INFONAVIT employer registration) | $3,500–$4,500 | $0 | $0 | $3,500–$4,500 |
| Monthly accounting, payroll, CFDI, IMSS/INFONAVIT filings (flat $1,000–$1,500/mo) | $12,000–$18,000 | $12,000–$18,000 | $12,000–$18,000 | $36,000–$54,000 |
| Annual statutory items (corporate book, annual SAT filing) | $0–$1,000 | $0–$1,000 | $0–$1,000 | $0–$3,000 |
| Total entity (5 employees, 36 months) | ~$40,000–$62,000 |
See the full breakdown of incorporation costs in Mexico for line-item detail by entity type and state.
The crossover happens at ~3 employees. Below 3, EOR is dramatically cheaper. At 3, costs are roughly equivalent. At 5 employees, the entity route runs 25–50% cheaper over 3 years. By 10 employees, entity is ~60–70% cheaper. The reason is structural: EOR scales linearly with headcount while entity overhead stays largely fixed.
A note on what cost doesn’t capture. Even when entity is cheaper on paper, EOR may be worth the premium if your team has zero bandwidth for Mexico oversight. EOR means zero management overhead for the foreign team — no Mexican director coordination, no statutory filings to track, no banking relationship to maintain, no annual corporate book to keep current. A well-run Mexican entity is never quite “zero ops” even when a Mexico specialist handles the day-to-day. If your CFO is already at capacity, paying the EOR premium for that simplicity is a defensible call. We’ll tell you when that’s the right answer — about 1 in 5 of our clients stays on EOR for exactly this reason.
Important caveats:
- At 1–2 employees, EOR is dramatically cheaper. Don’t incorporate for one hire.
- At 3 employees, costs are roughly even — pick on the qualitative axes (IP, PE risk, manufacturing, invoicing, oversight bandwidth).
- At 4+ employees, entity wins on cost, with the gap widening fast.
- If you have one-time spikes (a 4-month consulting engagement, for example), EOR is almost always right regardless of headcount.

The decision framework: 6 questions
If you’re stuck, answer these six questions and follow the lean. Each “lean entity” answer is worth roughly 1 point; tally below.
1. How many people will you hire in Mexico in the next 12 months?
- 1–2 → lean EOR.
- 3 → break-even on cost; decide on the other questions.
- 4+ → lean entity.
2. Are you committing to Mexico for 3 or more years?
- No, this is a pilot or under 12 months → lean EOR.
- Yes, multi-year operating commitment → lean entity.
3. How sensitive is the work — IP, manufacturing process, regulated activity?
- Low — sales coverage, customer success, BD → lean EOR.
- High — engineering, R&D, manufacturing, regulated services → lean entity.
4. Will you manufacture, import, or invoice in Mexico (CFDI to Mexican buyers)?
- No → lean EOR.
- Yes (any of the three) → lean entity. Often non-negotiable.
5. What’s your setup budget and time pressure?
- Need first hire in 5 business days, no setup capital available → start with EOR.
- Have 8–12 weeks and ~USD $3,500–$4,500 for setup → entity is open.
6. Does your team have bandwidth to oversee a Mexican entity?
- No — leadership is at capacity, no one wants to learn Mexican corporate housekeeping → lean EOR even if it costs more.
- Yes — we have a CFO or COO who can own this, even at a light touch → entity is viable.
Tally: if 3 or more answers lean entity, plan to incorporate. If 3 or more lean EOR, start with EOR — and revisit when headcount or commitment crosses the threshold. For incorporation timing specifically, see our 8–12 week incorporation timeline.
Switching from EOR to your own entity
Most companies that incorporate in Mexico start on EOR. The path looks like this:
- Incorporate the new Mexican entity. Notary, RFC, SAT, opening of Mexican bank accounts. 8–12 weeks.
- Register the new entity as an employer. IMSS and INFONAVIT employer setup — typically 2–3 weeks running in parallel with the back end of incorporation.
- Plan the employee transition. Employees terminate from the EOR and onboard to the new entity on a defined date. Done correctly, this is invisible to the employee — same pay, same role, new payslip header.
- Settle severance and seniority. Mexican law treats accrued seniority carefully. The EOR usually pays out aguinaldo (the mandatory year-end bonus, minimum 15 days’ salary), pro-rated PTU (the 10% statutory profit-sharing distribution if applicable), and accrued vacation. The new entity starts a new seniority clock unless you formally recognize prior tenure (recommended — it preserves morale and reduces wrongful-dismissal exposure).
- Run final EOR and first entity payroll cycle. Most transitions happen on the 1st or 16th of a month to align with Mexico’s bi-monthly CFDI payroll cadence.
Done well, the transition takes ~12 weeks end-to-end and employees experience no disruption. Done badly, you create a severance event you didn’t have to. This is a moment where having a Mexico specialist matters — see how hiring works in Mexico for the operational detail.
Outsourcing, REPSE, and the 2021 reform — what every buyer needs to know
Mexico rewrote its outsourcing law in 2021. The reform did three things that materially affect the EOR-vs-entity decision:
- Generic personnel-leasing was banned. You cannot lawfully “rent” employees from a third party to perform your core business.
- Specialized services were carved out. Activities outside your core business can be performed by a third party — but only if that provider is registered in REPSE, a public registry maintained by STPS (the labor ministry).
- Joint and several liability for unpaid wages, IMSS contributions, and tax was extended to the contracting party (you) when working with a non-REPSE provider.
For the EOR-vs-entity decision, this means: EOR work must run through a REPSE-registered provider. If you choose EOR, ask for the provider’s REPSE certificate and verify it on the public STPS registry. If you choose your own entity, REPSE doesn’t apply to your direct employees — they’re employees of your entity, not outsourced personnel. For the full walkthrough, see REPSE registration explained.
What Start-Ops does
Start-Ops Mexico is a Guadalajara-based firm that helps foreign companies — primarily US and Canadian — start and run operations in Mexico. We handle entity formation (S de RL de CV and SA de CV), RFC and SAT registration, IMSS and INFONAVIT employer setup, ongoing accounting and payroll, CFDI issuance, employment contracts, severance and terminations, expat visas, and IMMEX manufacturing setup. We also offer EOR for clients who need it.
About 4 in 5 of our clients ultimately incorporate their own Mexican entity. The remaining fifth stay on EOR — sometimes permanently, more often for 6–18 months while they prove out the market. We work with both.
What we don’t do: pretend that Mexico is one tile in a 150-country grid. Our entire team is Mexican, English-speaking, and based in Guadalajara. When something complex comes up — a tax authority audit, a severance dispute, an IMSS reclassification — you’re talking to people who have walked into the relevant government office in person.

Frequently asked questions
For 1–2 employees, EOR is dramatically cheaper. At 3 employees, the costs are roughly equivalent. At 4+ employees, your own Mexican entity is almost always cheaper because entity overhead (accounting, payroll, CFDI, IMSS/INFONAVIT filings) is largely fixed, while EOR fees scale per-head. By 5 employees, entity is 25–50% cheaper over 3 years. By 10, the gap exceeds 60%.
Incorporation takes 8–12 weeks end-to-end for a foreign-owned S de RL de CV or SA de CV. The phases are: power of attorney and document apostille (1–2 weeks), notary public formation and constitutive act (2–3 weeks), RFC registration with SAT (1–2 weeks), IMSS and INFONAVIT employer registration (2–3 weeks), and bank account opening (parallel, 2–4 weeks). See our 8–12 week incorporation timeline.
Yes, in most sectors. Mexico’s Foreign Investment Law allows 100% foreign ownership in nearly all activities — software, professional services, manufacturing, B2B services, e-commerce. A short list of restricted sectors (certain transportation, broadcasting, and resource extraction) limits foreign ownership. Your nationality doesn’t restrict ownership of a standard S de RL de CV or SA de CV.
No, you do not need a Mexican national as director, shareholder, or partner. You do need at least one director or sole administrator, who can be a foreign national, and at least two shareholders for an S de RL de CV (one of them can be the parent company). A Mexican legal representative with a Mexican tax ID is required to interact with SAT — this is typically a Mexican attorney or accountant, not a controlling shareholder.
S de RL de CV has no fixed legal minimum — capital can be as low as MXN $3,000 (~USD $180), though notaries typically recommend MXN $10,000–$50,000 for credibility with banks and counterparties. SA de CV has a higher conventional minimum, typically MXN $50,000 (~USD $3,000), though the legal floor was removed years ago. In practice, both entity types fund operating capital separately from initial subscribed capital.
REPSE is the Registry of Specialized Service Providers, established by Mexico’s 2021 outsourcing reform. It applies to third-party providers of specialized services, including EOR providers. If you employ workers directly through your own Mexican entity, REPSE does not apply to your in-house workforce. REPSE only matters if you outsource work to another company. See REPSE registration explained.
Roughly 12 weeks end-to-end, running mostly in parallel with incorporation. The new entity needs to be incorporated and registered with IMSS/INFONAVIT (8–12 weeks), then employees transition on a clean payroll-cycle date. The transition itself takes 1–2 weeks of execution; the prep takes 8–12.
An EOR (Employer of Record) is the legal employer of your Mexican workers — it owns the labor contract. A PEO (Professional Employer Organization) is a co-employer that requires you to already have your own Mexican entity. Most US buyers asking for a “PEO in Mexico” actually need an EOR. Post-2021, PEO arrangements in Mexico are heavily constrained by the outsourcing reform; EOR via a REPSE-registered provider is the standard model.
Yes — and through your own entity too. Aguinaldo (Christmas bonus, minimum 15 days’ salary, paid by December 20) and PTU (10% of pre-tax profits, paid by May 30) are mandatory under the Federal Labor Law for all Mexican employees regardless of who the employer of record is. Under EOR, the EOR pays these from the funds you provide; under your own entity, you pay them directly. There’s no path that avoids them legally.
Yes, and many of our clients do. A common pattern: incorporate the entity for engineering and key roles, keep sales reps and short-term contractors on EOR. There’s no legal barrier to a foreign parent operating both a Mexican subsidiary and an EOR relationship simultaneously, as long as roles aren’t duplicated or restructured to dodge labor obligations.
