Outsourced Controller Services for Growing Companies
What makes us different?
A controller is the operational leader of the accounting function — the person who owns the close process, ensures the accuracy of financial statements, manages the accounting team, and maintains the general ledger. For many companies, the gap between a bookkeeper and a full-time controller is a difficult one to bridge — bookkeepers lack the technical depth and management capability a controller provides, but a full-time controller hire is often premature.
Corviniti provides outsourced controller services that bridge that gap. We take ownership of the accounting function at the controller level — managing the close, reviewing reconciliations, preparing financial statements, and ensuring the books are accurate, consistent, and audit-ready. We operate as a member of your team, not as an outside vendor processing transactions.
Our controller professionals are Big 4-trained CPAs with the technical depth to handle complex accounting questions as they arise — which distinguishes our service from traditional bookkeeping or accounting outsourcing. When a new contract raises a revenue recognition question or an equity issuance requires technical accounting analysis, we handle it directly rather than escalating it to a separate advisor.
We help with:
- Month-End Close Management: Own and manage the full monthly close process — journal entries, account reconciliations, financial statement preparation, and review of supporting schedules.
- Financial Statement Preparation: Prepare GAAP-compliant balance sheets, income statements, cash flow statements, and statements of equity on a monthly, quarterly, and annual basis.
- General Ledger Oversight: Maintain a complete, accurate, and well-organized general ledger with consistent account coding and clean supporting documentation.
- Account Reconciliation Review: Review and approve all balance sheet reconciliations, ensuring they are complete, accurate, and supported by appropriate documentation.
- Management Reporting: Prepare tailored management reporting packages — financial summaries, variance analysis, and KPI dashboards — for management and board review.
- Technical Accounting Compliance: Apply US GAAP or IFRS standards consistently across all transactions, handling complex accounting questions as they arise during the close.
- Audit Preparation: Build and maintain audit-ready workpapers, reconciliations, and supporting schedules throughout the year so external audits proceed efficiently.
- Accounting Team Management: Manage and develop the internal bookkeeping and accounting staff, providing direction, review, and quality control.
- Accounting Policy Application: Ensure accounting policies are applied consistently across all periods and that new transactions are accounted for in accordance with established policies.
- Systems and Process Improvement: Identify and implement improvements to the close process, accounting systems, and internal workflows that improve accuracy and efficiency.

Frequently Asked Questions
A bookkeeper records financial transactions, reconciles bank accounts, and maintains the general ledger. A controller manages the full accounting function — overseeing the close process, preparing financial statements, reviewing the work of bookkeeping staff, handling complex accounting questions, and ensuring the financial records comply with GAAP. The controller is the technical accounting leader of the organization; the bookkeeper is the transaction processor.
A controller is primarily focused on the accounting function — financial record-keeping, close management, financial statement preparation, and compliance. A CFO operates at the strategic level — advising management on financial decisions, managing investor and board relationships, overseeing capital allocation, and leading fundraising and transaction activities. Many companies need both; others start with a controller and add CFO-level advisory as the business grows.
Yes. In most outsourced controller engagements, your existing staff continues to handle day-to-day transaction processing, and our controller provides the oversight, review, and management layer above them. We review their work, manage the close process, prepare the financial statements, and handle the accounting questions that are beyond the team’s technical capability.
Complex transactions — equity issuances, debt modifications, revenue recognition questions, lease modifications — are handled directly by our controller professionals, who have the technical accounting depth to analyze and document them correctly. We do not escalate these to a separate advisor or ask you to figure them out independently. The controller function includes technical accounting capability, which is what distinguishes our service from traditional bookkeeping or accounting outsourcing.
Audit-ready means that when your external auditors arrive, they receive a complete, organized package of financial statements, supporting schedules, and reconciliations that agree to the general ledger. Every balance sheet account has a reconciliation with supporting documentation. Journal entries have clear descriptions and support. Accounting policies are documented. There are no significant open items or unresolved questions. We maintain this state of readiness throughout the year, not just at year-end.
Most companies hire a full-time controller when the complexity of the accounting function exceeds what an outsourced arrangement can efficiently manage — typically when the company has a significant internal accounting team that requires full-time management, multiple entities or complex consolidations, or a transaction or regulatory environment that requires dedicated on-site presence. We help identify when that point is approaching and support the transition when it happens.
Yes. We regularly work with foreign private issuers and companies with cross-border structures, including IFRS reporting, US GAAP reconciliations, and multi-entity consolidations for companies with domestic and international subsidiaries.
In most cases, we can begin within a few days of finalizing our agreement. Our onboarding process is straightforward — a brief discovery session, a clear statement of work, and secure access setup. We do not have lengthy intake procedures that delay the start of actual work.
