Accounting, Tax & Cross-Border Advisory for U.S.–Mexico Operations
We help U.S., Mexican and international companies coordinate accounting, federal tax, financial reporting, payroll and compliance across both sides of the border — with one team that understands how the entire operation fits together.

Cross-Border Complexity
Your business may operate as one company. Your advisors often do not.
Expanding between the United States and Mexico creates dependencies between entities, financial teams, payroll systems, reporting calendars and regulatory obligations. The problems usually begin when each part is managed independently.
Cross-border complexity comes from managing both countries as if they were unrelated.
01
Different advisors. No single owner.
No one is responsible for coordinating how decisions in one country affect the other.
02
Financial reporting does not align.
Different systems, calendars and formats slow down decisions at headquarters.
03
Tax decisions cross borders.
Intercompany services, loans and dividends can create consequences in both jurisdictions.
04
Compliance calendars become fragmented.
Management lacks a unified view of what must happen and when.
05
Management receives data instead of answers.
Information exists, but does not show where risks and priorities sit.
Integrated Business Services
The services your U.S. operation needs — coordinated around one business.
Most international companies do not need more providers. They need better coordination between accounting, tax, payroll, reporting and compliance.

Learn more →Our Cross-Border Advantage
One operation. Two jurisdictions. One coordinated team.
A company may have a legal entity in the United States and another in Mexico, but management still thinks about revenue, cash flow, people, margins and growth as one business. That is how we approach cross-border advisory.
Rather than treating each country as an isolated compliance project, AS Consulting Group coordinates the financial, tax and operational information that connects both sides.
Mexico → United States
Coordinate funding, accounting, payroll, reporting and related-entity transactions before fragmented processes become permanent.
United States → Mexico
Improve visibility over local accounting, reporting, tax, payroll and recurring compliance in the Mexican operation.
One Point of Coordination
Connect local execution with the broader firm so management does not have to coordinate every jurisdiction alone.
Who We Help
Built for companies operating across borders — not just across state lines.
We work best with companies that need coordinated thinking across entities, markets and management teams.
Mexican companies expanding into the U.S.
Build accounting, payroll, reporting and compliance with the international structure in mind.
U.S. companies operating in Mexico
Improve coordination between U.S. management and local teams in Mexico.
Foreign-owned U.S. subsidiaries
Bridge local requirements and the reporting standards of an international parent.
Mid-market international businesses

Professional services & technology

Beyond Compliance
Financial information should give management control.
A company can be fully compliant and still lack the information needed to manage effectively. We connect local financial information with the way management needs to see the business.
Compliance tells you whether the company met an obligation. Financial control tells you whether management understands the business.
Monthly reportingReliable information available in time to support decisions.
Headquarters alignmentConsistent reporting across local teams and international management.
Intercompany reconciliationIdentify inconsistencies before they accumulate.
Cash & obligationsBetter visibility over accounts, deadlines and responsibilities.
CFO supportComplement finance leadership without unnecessary internal expansion.
Management clarityTurn accounting data into a coherent view of the operation.
