About Us

From a local firm to a binational platform

Since 1991, we have built a professional services firm designed for companies that don’t fit within a single border. What began as an accounting practice in Mexico is now a platform with a presence in Mexico, the United States, Spain, and Asia, integrated into the SMS Latinoamérica network. We help Spanish and European companies establish operations in the Americas, and American companies to operate in Europe, under a single quality standard and a single point of contact.

 

Why choose us

Specialists in eliminating the financial challenges of your international expansion

Coordinating accountants, tax specialists, lawyers, and auditors across three different countries shouldn’t be your problem. At AS Consulting Group, we bring together in one firm everything that would normally require four providers in Mexico, the United States, and Spain — under a single contract, one team, and consolidated reporting.

Clear processes from day one

Every project begins with a diagnostic session with the specialist for your market. We identify risks, map out the compliance roadmap, and set deliverables — with no surprises or bureaucracy.

A dedicated team for your industry and market

We don’t work with generalists: each Desk masters the tax and operational regulations of its jurisdiction. Your company enters each market backed by local experts, not improvisers.

 

Agile support during business hours

We offer fast responses to address initial questions, preliminary reviews of your tax situation, and specialized materials on expansion and cross-border tax. You are never alone in the process.

We are committed to your growth

We support Spanish, Mexican, and U.S. companies as they expand, meet their tax obligations, and scale with full financial control — under one provider and one standard.

Who We Are

A multinational firm built to support you from start to finish

AS Consulting Group is a multidisciplinary firm with real operations in Mexico, the United States, Spain, and Asia. Accountants, tax specialists, auditors, corporate lawyers, and M&A experts work in coordination to deliver a truly integrated experience — not a patchwork of isolated services.

What makes us unique is not only our geographic reach, but the way we execute: we develop our own technology tools for CFDI processing, real-time financial dashboards, and compliance engines, instead of relying on generic software. Every deliverable reflects standardized criteria across accounting frameworks and jurisdictions.

We speak the language of each market — literally. Spanish, English, Mandarin, Portuguese, and French. Because international expansion requires more than technical expertise; it requires frictionless communication with every team, authority, and partner in the destination market.
