Who We Serve
We offer cross-border tax compliance, outsourced accounting, audit, and financial reporting services for businesses and individuals operating across the US, Canada, and Australia. Our typical client operates across more than one jurisdiction, has outgrown generic accounting solutions, and needs a firm that understands the cross-border implications of every financial decision they make.

Foreign-Owned Entities and Non-Resident Founders
You have set up a US LLC or corporation to access the American market, but as a non-resident owner, your filing obligations go far beyond a standard tax return. From mandatory Form 5472 and pro forma 1120 filings to ITIN applications and state tax compliance, the IRS has specific requirements for foreign-owned entities that most general accountants are not equipped to handle. We are. We make sure your US entity is fully compliant from day one, so a $25,000 penalty never appears on your radar.

E-Commerce Businesses and Online Sellers
As a cross-border e-commerce seller, you are managing inventory, suppliers, platforms, and customers across multiple countries. The last thing you need is to be navigating two tax systems at the same time. We handle your US and Canadian tax filings, sales tax compliance, bookkeeping, and multi-currency reconciliations so you can focus on growing your store and your margins.

Remote-First Companies and SaaS Businesses
Your team is distributed across the US and Canada. Your revenue crosses borders. Your payroll, entity structure, and tax obligations follow suit. We work with remote-first companies and SaaS businesses to handle cross-border payroll structuring, multi-entity accounting, and tax compliance across both jurisdictions, keeping your operations clean and your books investor-ready at every stage of growth.

Businesses Requiring Audit, Assurance, and Investor-Grade Reporting
You are raising capital, preparing for an audit, or need financial statements that meet IFRS, ASPE, or US GAAP standards. Banks, investors, and regulators will look closely at your numbers. We prepare financial statements and audit-ready records built to hold up under that scrutiny, so you can walk into any financing or due diligence conversation with confidence.
OUR PROCESS
Clarity Before Any Work Begins
01
Free Consultation Call
This is a discovery call where we discuss your current cross-border tax and accounting situation, your business structure, the jurisdictions you operate in, and what you need. It is also a chance for you to learn about us and how we work. If there is a clear opportunity for us to add value, we move to the next step.
02
Gathering Information
We prepare a detailed questionnaire and request your prior tax returns, financial statements, entity structure documents, and any other relevant information. The goal at this stage is to build a complete picture of your current compliance position across every jurisdiction your business touches.
03
Assessment and Gap Review
This is where our audit background earns its place. We review your prior filings and financial records with a senior auditor's eye, identifying compliance gaps, filing errors, missed deductions, and any risks that need to be addressed. A majority of new clients we work with have at least one issue that their previous accountant missed.
