Outsourced Controller Services for Growing and Mid-Market Companies
What makes us different?
The controller is the operational leader of the accounting function — the person who owns the close, ensures the accuracy of financial statements, manages the accounting team, and maintains the discipline that reliable financial reporting requires. For many growing companies, hiring a full-time controller is either premature or impractical, but relying on a bookkeeper to fill that role creates gaps that consistently surface at the worst possible time — during an audit, a due diligence process, or a capital raise.
Corviniti provides outsourced controller services that give companies controller-level accounting leadership without the cost of a full-time hire. We take ownership of the accounting function — managing the close process, overseeing reconciliations, preparing financial statements, and handling the technical accounting questions that arise in a real business. We operate as part of your team, not as an outside vendor.
The distinguishing feature of our outsourced controller service is technical depth. Our professionals are Big 4-trained CPAs who can handle revenue recognition questions, equity accounting, lease accounting, and other complex issues directly — without escalating to a separate technical advisor. That capability is what separates a true controller service from sophisticated bookkeeping.
We help with:
- Monthly and Quarterly Close Management: Own and manage the complete close process — journal entries, account reconciliations, subledger tie-outs, and financial statement preparation — every period.
- Financial Statement Preparation: Prepare GAAP-compliant income statements, balance sheets, cash flow statements, and statements of equity on a monthly, quarterly, and annual basis.
- General Ledger Management: Maintain a complete, accurate, and well-organized general ledger with proper account coding, consistent policies, and clean supporting documentation.
- Account Reconciliation Oversight: Review and approve all balance sheet account reconciliations, ensuring every balance is supported and open items are resolved promptly.
- Technical Accounting Issue Resolution: Handle complex accounting questions — revenue recognition, lease accounting, equity instruments, debt modifications — as they arise during the close, without separate escalation.
- Management Reporting: Prepare monthly management reports, variance analysis, and KPI dashboards for management and board review.
- Audit Preparation and Support: Maintain audit-ready workpapers throughout the year and manage the annual audit process on management’s behalf.
- Accounting Team Oversight: Manage and develop the internal bookkeeping and accounting staff, providing direction, review, and quality control.
- Accounting Policy Compliance: 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 reporting workflows that improve accuracy and efficiency over time.

Frequently Asked Questions
A bookkeeper records transactions, reconciles bank accounts, and maintains the general ledger at an operational level. An outsourced controller manages the full accounting function — overseeing the close process, preparing financial statements, reviewing the bookkeeper’s work, handling complex accounting questions, and ensuring GAAP compliance. The controller brings technical accounting expertise and management capability that bookkeepers do not provide.
A controller is focused on the accounting function — financial record-keeping, close management, and financial statement accuracy. A CFO operates at the strategic level — advising on financial decisions, managing investors and the board, overseeing capital allocation, and leading fundraising. Many companies need both; some start with an outsourced controller and add CFO-level advisory as strategic needs develop.
Yes. Most outsourced controller engagements are structured as a co-sourcing arrangement — your existing staff handles day-to-day transaction processing, and our controller provides the oversight, review, and management layer. We manage the team, review their work, and ensure the close process runs correctly.
Complex transactions — equity issuances, new financing arrangements, revenue recognition questions, lease modifications — are handled directly by our controller professionals. We analyze the accounting, prepare the journal entries and supporting documentation, and ensure the close reflects the correct treatment. This is what distinguishes our service from bookkeeping — the technical capability to handle complexity without outside escalation.
Audit-ready means that at any point in the year, your financial records are in a state that could withstand audit review — reconciliations are current and supported, journal entries are documented, accounting policies are applied consistently, and there are no significant unresolved questions. We maintain this standard throughout the year, not just in the weeks before the auditors arrive. The result is an annual audit process that is faster, lower-cost, and less disruptive.
Most companies hire a full-time controller when the complexity or volume of the accounting function requires full-time dedicated management — typically when there is a significant internal accounting team requiring daily oversight, multiple entities requiring consolidation, or a regulatory environment requiring on-site presence. We help identify when that transition is approaching and support the search and onboarding process.
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.
