About Us
You have the clients. We build the team behind them.
100 dedicated, supervised workstations in Mexico City
"Global growth starts with the right team, the right infrastructure, and the right partner".
Luis Javier Arreguín, MBA, CPF – CEO ASCG
"You don't outsource your firm. You extend it."
100 dedicated, supervised workstations in Mexico City — the same business hours as your firm.
The Real Bottleneck
The Bottleneck Isn't Clients. It's People.
Every firm hits the same wall - not enough hands, not enough hours, not enough time to hire.
Missed Opportunities
Stop turning down work because you can't hire fast enough.
Beyond Local Talent
Your growth shouldn't depend on finding another accountant in your zip code.
Empty Seats
Every unfilled seat is a client you can't take on.
The Talent Gap
Local hiring pools don't grow as fast as your firm does.

FAQs
Questions Managing Partners Ask Before Starting.
A freelance marketplace connects you to an anonymous individual working from home, with no oversight. The GSC is the opposite: a dedicated, supervised operation inside AS Consulting Group, where every professional is recruited, trained, and supervised directly by the firm — not sourced from a marketplace.
AS Consulting Group does, directly. Every professional assigned to your account goes through the firm's own recruitment, training, and supervision process before working on your account.
You work directly with your assigned team, inside your own tools, processes, and business hours — no unnecessary intermediaries.
From a dedicated facility in Mexico City with 100 physical, supervised workstations — never from someone's home or a freelancer's personal laptop.
On-site supervision, managed equipment, a controlled environment, and signed confidentiality agreements (NDA) with every professional — under documented, verifiable protocols.
Yes, through documented, auditable protocols (not an absolute guarantee): controlled access, managed devices, and an individual NDA signed by every assigned professional.
Accounting & Finance Support, U.S. Tax Preparation Support, and Bilingual Administrative Support, including bookkeeping, reconciliations, payroll administration, workpapers, back-office operations, and tax preparation support.
The GSC extends your operational capacity. Review, approval, and professional responsibility for every deliverable remain fully with your firm's own controls and signature.
No. Your team works inside your own processes, tools, and standards — it's not a new system you have to learn.
No. You can start with a single dedicated position and scale up as your firm's needs grow.
Typically 2 to 3 weeks: a diagnostic session, team assignment, and integration into your systems and processes.
Yes — the same time zone as your firm (CST/EST), so there's no lag in communication or turnaround.
