Start-Ops handles the full incorporation in Mexico stack — entity formation, RFC, RNIE foreign-investment registration, and a working Mexican bank account — so your subsidiary is operating in weeks, not months.

Setting up a Mexican subsidiary looks simple on paper. In practice, the choice of entity, the foreign-investment registration, the bank account, and the RFC are linked steps that go wrong in subtle, expensive ways.
A friend-of-a-friend notario sets up an S de RL de CV — but skips the RNIE filing, picks the wrong shareholder structure for a foreign parent, or leaves the RFC and e.firma to figure out later. Six months in, you can’t open a bank account, you can’t issue CFDI invoices, and your entity exists on paper but can’t operate.
A clean deck and a $25,000 invoice. Worse, the Big 4 hands you off after formation. Nobody owns the bank account opening, the ongoing CFDI provisioning, or the monthly accounting. You’re back to coordinating four vendors yourself.
You delay incorporation and pay people in Mexico as 1099 contractors. Mexico aggressively reclassifies contractors as employees — triggering retroactive severance, IMSS contributions, and joint liability that can dwarf the cost of doing it right from day one.
Start-Ops is built for the COO, CFO, or GM of a foreign company opening a Mexican entity for the first time. We handle formation, RNIE, banking, tax registration, and the operational handoff into accounting and payroll — under one roof, in your time zone, in plain English.
Formation, legal, tax, accounting, payroll, and HR under one roof — no juggling three vendors and a notario.
Every contract, filing summary, and update in clear English — with the Spanish originals attached.
Real humans answering during US business hours — not a ticket queue in another time zone.
Specialists in foreign-shareholder structures, RNIE filings, and the bank-account hurdles that trip up generic local firms.
We map your shareholders, capital structure, and operational plan, then recommend the right entity (S de RL de CV vs SA de CV), capital amount, and legal representative setup. You sign off before anything is filed.
We draft the constitutive act, run the notario público appointment, and register the company with the Public Registry of Commerce (RPC) and SAT for your RFC and e.firma — the digital signature you’ll need for everything else.
We file your foreign-investment registration (RNIE), open the corporate Mexican bank account, and provision your CFDI invoicing so the entity can transact, invoice, and receive funds the day it goes live.
We hand off into ongoing accounting, payroll, tax filings, and IMSS employer registration — so your new Mexican entity stays compliant from month one without you hiring an in-house team.
A working Mexican entity — fully registered, with RFC, e.firma, RNIE filed, and CFDI provisioned — typically takes 6 to 9 weeks with Start-Ops. The single biggest variable is the corporate bank account, which can add 2 to 6 weeks depending on the bank’s foreign-shareholder onboarding pace. We start the bank conversation on day one to avoid surprises.
The S de RL de CV is the Mexican LLC — fewer shareholders, simpler governance, and often cleaner tax treatment for US parents (it can elect to be treated as a pass-through for US tax purposes). The SA de CV is the Mexican corporation — more flexible for share transfers and outside investors. Most foreign-owned subsidiaries we set up are S de RL de CV. We’ll recommend the right one based on your shareholder structure and US tax goals.
No. Mexico allows 100% foreign ownership in almost every sector. You do, however, need a legal representative in Mexico who can sign on behalf of the company and a Mexican tax address — both of which Start-Ops provides as part of the engagement.
Start-Ops entity setup is a one-time fee of $3,500–$4,500 USD, depending on shareholder complexity and structure. Ongoing monthly compliance — bookkeeping, tax filings, statutory reporting — runs $1,000–$1,500 USD per month, scaling with transaction volume and headcount. No surprise invoices, no hourly partner billing.
Yes — without a Mexican bank account, your entity can’t pay vendors, run payroll, or receive client payments. Foreign-shareholder bank account opening is the hardest single step in Mexican incorporation and is where most DIY paths fail. Start-Ops handles bank introductions, KYC packaging, and accompaniment to the in-person account opening with the legal representative.
For the first 1 to 10 employees in Mexico, often yes — and many of our clients start with our Employer of Record service before incorporating. Once you cross ~10 employees, plan to operate long-term in Mexico, or need to invoice Mexican customers locally, your own entity is almost always cheaper and cleaner. We can run EOR and entity formation in parallel and migrate your team when you’re ready.
