THE PROBLEM
Mexican accounting isn't bookkeeping — it's a regulated process with monthly deadlines.
SAT requires electronic accounting, monthly ISR and IVA filings, CFDI invoices for every sale and every payroll receipt, and an annual return with full reconciliations. Miss a filing and SAT can freeze your bank accounts.
01 — The freelance contador
Charges by the hour, replies in days, sends Excel sheets in Spanish. Fine until you need a clean trial balance, a year-end close, or a defensible position during a SAT review.
02 — The in-house junior
One person handling accounting, HR, and admin. Misses CFDI windows, can’t reconcile to your group’s chart of accounts, and there’s no backup when they’re out.
03 — The generic Mexican firm
Quarterly emails in Spanish. No bridge to your US GAAP or IFRS reporting. Group audit stalls because nobody can reconcile the Mexican books to the consolidation.
WHAT YOU GET
Outsourced accounting that closes the Mexican books — and bridges to your group reporting.
Start-Ops handles your full Mexican accounting stack: bookkeeping, CFDI, SAT filings, payroll booking, and monthly statements your CFO can drop straight into the consolidation.
One firm, full Mexico stack
Accounting, tax, legal, payroll, and HR consolidated. One contact, one invoice, one monthly close.
Foreign-parent fluent
Mexican-statutory books and a parent-ready reporting package in the same close. No translation step on your side.
US-time-zone responsive
Monthly reports, variance commentary, ad-hoc questions handled during your business hours — not next week.
SAT-compliant by default
Electronic accounting, CFDI invoicing, and monthly filings done correctly the first time — not patched after a notice arrives.

FAQ
The questions foreign companies ask about accounting in Mexico.
Pricing depends on transaction volume, headcount, and whether you need bilingual reporting and audit support. Most foreign-owned entities with under 50 employees fall into a fixed monthly fee that covers bookkeeping, all SAT filings, payroll accounting, and monthly statements. We send a flat-fee quote after the intake call — no hourly billing.
A Mexican accountant (contador público) handles SAT-mandated electronic accounting, monthly ISR and IVA filings, CFDI invoicing, payroll-receipt stamping, and annual returns in Mexican format. None of this is required in the US, and most of it is automated through SAT-certified software US accountants don’t use.
Yes. We deliver your monthly financials in English, in your group’s reporting format, alongside the Mexican-statutory books. We also coordinate directly with your external auditors during year-end and provide support to a statutory dictamen fiscal where required.
If you’re only using an EOR and have no Mexican entity, the EOR handles all entity-level accounting. The moment you incorporate your own Mexican subsidiary, you need full corporate accounting — bookkeeping, SAT filings, CFDI, and statements. Most clients move from EOR to their own entity within the first 12–18 months.
We respond on your behalf, prepare the supporting documentation, and coordinate with legal and tax counsel if the matter escalates. Because we run the books, we already have everything SAT will ask for.
Yes. We issue, validate, and store every CFDI 4.0 invoice your entity sends to its customers, manage cancellations and replacements within SAT’s window, and reconcile invoicing to revenue on a monthly basis.
