Your route

How will you enter Mexico?

Each route has different risks and steps. Choose yours and see the order in which things should be done.

Your route into Mexico

Choose how you'll enter and what you have today. We show you the steps, the order and where the risks usually are.

–

Indicative route. Timelines depend on the notary, the bank, the authorities and how complete the target company's information is. We tailor them to your case on the initial call.

What worries investors from abroad

Investing from abroad carries risks that don't show in the financial statements

1

Contingencies that don't show on the balance sheet

Taxes from open years, gaps with IMSS or suppliers on the 69-B list. If you buy shares, they're yours from closing day.

2

No one you trust in Mexico

The bank, the SAT and IMSS require a representative with powers of attorney and a real address. Without them, the account doesn't get opened and notices get lost.

3

Operations headquarters can't see

Invoices, collections, payments and payroll in another language, under other rules and without clear reports. Decisions come too late.

Investor questions

What ask first foreign investors

What contingencies do I inherit?

Unpaid taxes, social security contributions, labor lawsuits, suppliers on the 69-B list or poorly signed contracts. Due diligence quantifies them before you set the price.

How do I repatriate profits?

Dividends to non-residents carry a 10% withholding tax, which a tax treaty may reduce. If they come from already-taxed earnings (CUFIN) there's no additional corporate income tax. We plan it from the start.

Can I open a bank account?

Yes, but the bank requires a tax ID, e.firma, a verifiable tax address, a representative with powers of attorney and beneficial ownership information. We arrive with the complete file.

Who signs before the SAT and the bank?

The company needs a legal representative with an e.firma and sufficient powers. If you don't have someone you trust in Mexico, we provide that service with controls and reporting to headquarters.

Do I need an office?

You need a real tax address where the authorities can locate you. An address that doesn't respond can end in your invoicing certificate being restricted. We provide a registered tax address that receives notices.

How do I hire staff?

With a contract, social security registration, stamped payroll and statutory benefits. Staff subcontracting has been prohibited since 2021, so staff must be on your payroll or on that of a REPSE-registered provider.

How do I handle transactions with my group?

Transactions with headquarters must be priced at arm's length and, depending on size, documented with a transfer pricing study.

How do I know what's happening at my subsidiary?

With monthly accounting, English reports for headquarters and the AO INSIGHT dashboard: cash flow, receivables and payables, payroll and obligations in one place.

Frequently asked questions

What clients usually ask us

Do you work in English?

Yes. Calls, due diligence reports and monthly reports for headquarters can all be in English.

Does the due diligence include legal?

Yes. Our team reviews accounting, tax, legal and labor matters and, depending on the issue, works with specialized outside counsel. We deliver a single report with quantified, prioritized findings.

What if the due diligence finds problems?

That's what it's for. With quantified findings you can adjust the price, ask for warranties or a holdback, require fixes before closing or decide not to buy.

Does the legal representative control my company?

Powers of attorney are limited to what's needed, and decisions and payment approvals stay with headquarters. Everything is documented and reported.

Does the tax address work for the bank and the SAT?

It's a real address where the authorities can locate you, and where we receive notices and forward them to you. We go over your chosen bank's requirements with you.

Can I hire just one part?

Yes. You can hire just the due diligence, just the representation and tax address, or the full back office.

How much does it cost?

It depends on the scope and the information you already have. After the assessment we send a written proposal with a fixed fee and no hidden charges.
