Running accounting for a multi-entity or multinational business is complex. You’re managing more than debits and credits — you’re managing structure, timing, and confidence in the numbers. Corporate accounting is what keeps that structure intact.
At Guerrero Advisors, we work with large and growing organizations that need experienced accounting leadership without adding layers of headcount. Our team helps clients build reliable accounting systems, manage consolidations, and ensure compliance with reporting standards and regulations across various jurisdictions. The result is financial data management teams can trust and leadership can act on.
What Corporate Accounting Services Involve
Corporate accounting services aren’t just one thing. It’s a collection of recurring disciplines that create stability — close calendars that don’t slip, reconciliations that tie out, and reports that hold up under audit.
Our work often starts by tightening the basics:
- Designing a structured month-end close process that eliminates last-minute cleanups.
- Standardizing reconciliations across entities and systems.
- Building schedules that reconcile intercompany activity and multi-currency balances.
- Producing consolidated financial statements that align with GAAP or IFRS.
We also support technical areas many internal teams struggle to maintain, such as lease accounting under ASC 842 or revenue recognition under ASC 606. When standards change, we document the accounting positions and update internal policies, so nothing is left to interpretation.
Built for Scale
Most of our corporate clients operate across states or countries, with multiple entities, currencies, or lines of business. That scale adds complexity — different ERPs, different calendars, and different local reporting requirements.
We help leadership bring that complexity under control. Guerrero Advisors builds reporting structures that handle:
- Multi-currency and multi-entity consolidations
- Cross-border accounting and local statutory alignment
- Intercompany eliminations and transfer pricing coordination
- Audit-ready documentation and internal control mapping
Our goal is straightforward: to create a clear, repeatable process that enables the finance function to run predictably month after month.
Technical Accounting and Compliance
As companies expand, the demand for technical accounting expertise grows rapidly. We provide guidance and hands-on support for complex standards including ASC 842, ASC 606, and IFRS 16. That includes setting up initial calculations, journal entries, and supporting documentation, then integrating those entries into ongoing reporting.
When auditors arrive, your files are ready — reconciled, labeled, and consistent with your stated policies.
System Integration and Automation
We help companies improve accounting operations without overhauling everything at once. Our team works within your existing ERP and reporting tools, building automation around recurring entries, consolidations, and variance reports.
The focus is always practical: fewer manual adjustments, cleaner data, and faster turnaround on reporting. Whether your company uses NetSuite, QuickBooks Enterprise, or a custom ERP, we bring process discipline that complements your technology.
Working With Finance Leadership
Guerrero Advisors supports CFOs, controllers, and accounting VPs who want to strengthen their close and reporting functions without adding layers of management. We can serve as fractional leadership or work alongside internal teams to build processes that stand on their own.
Our role often includes:
- Reviewing current accounting workflows and identifying friction points
- Implementing consistent approval and review procedures
- Developing dashboards and reports tailored to management needs
- Training staff on accounting policy updates or system changes
We stay involved until the process runs smoothly on its own.
Why Companies Choose Guerrero Advisors
Controllers and CFOs come to us for a few specific reasons:
- Their accounting teams are stretched thin, and monthly closes are inconsistent.
- Multi-entity consolidation is slowing down board reporting.
- Technical accounting standards aren’t being applied consistently.
- Audit preparation is often reactive rather than planned.
We fix those problems by creating structure — clean procedures, defined timelines, and clear accountability. Once those are in place, the accounting team can focus on analysis instead of corrections.

These are operational results, not theoretical ones.
FAQs
How are corporate accounting services different from managed accounting?
Corporate accounting focuses on structure and compliance for larger organizations — multi-entity consolidations, technical accounting, and audit readiness. Managed accounting focuses on day-to-day transaction processing and reporting.
Do you support global operations?
Yes. We work with companies operating under both GAAP and IFRS, coordinating with local teams to maintain consistent global reporting.
What size companies use these services?
Most clients are mid-market or enterprise-level organizations, often managing complex financial operations or preparing for expansion, audit, or acquisition.
Final Perspective
Outsourcing corporate accounting gives large companies the control and transparency they need to scale responsibly. When systems, processes, and standards align, leadership can focus on direction instead of reconciliation.
Guerrero Advisors helps companies build that structure. We combine accounting discipline with practical finance experience so every report, forecast, and decision is grounded in accurate information.
Clean data. Consistent process. Confident leadership. That’s the foundation of corporate accounting done right.
